Have any of you folks ever seen any thing like this? :wtf1: This is suppose to be Delo 15-40 oil that was put in my 01 LB7. :eek: The amount of miles on this is approx 2800 miles. I have seen some strange things over the years but I have never seen oil perform like this before.:confused: It is the consistincy of jell-o. & has a light green cast to it. I think the place that changed my oil put in a gear lube by mistake. I am in the process of getting a lab to tell me what this product is. Also I am having two shops send samples to Chevron & Cat. The place that changed the oil said that I put in some kind of treatment which I have not.:knight::mad: By the way this stuff will not drain out of the pan, you have to poke & dig at it with a screw driver.:eek: At this time, until I find out what this stuff is the truck is setting @ the repair shop. I can't see any metal in the samples that I have taken but that doesn't mean it is not there. The oil pressure was very strange. I think its time for a new engine! All I can say for sure is that there is a hell of a pissing contest coming between me & the oil change place.

If it was gear-lube it should have a very distinct odor to it,but then again Ive never seen gear-lube come out of an engine.That green color seems really strange also,anti-freeze?Will be interesting to see the lab results on this one.

I would talk to others that have had there oil changed there and ask them if they have had troubles.

Considering the cost of a new engine (which is probably where this is headed), I'd be getting a few samples and keep one for the record. I'd even have a notary public sign a sample and date it, if possible. This doesn't happen very often, but when it does, the fighting between possible paying parties will go on for a LONG time. Do you have the receipt for the service done 2800 miles ago? Do you have receipts for all the service done in the last couple of years? The more you can doccument in your favor, the better.

It's likely one of two things happened. Either there was a gross coolant intrusion, which causes the potassium to react with the oil, or they used the wrong lubricant. The coolant could be from a blown head gasket, etc. Being a LB7, it's out of warranty, right?

If it were the wrong lube used, how in the world would they use so much of the "wrong" lube? I can't imagine filling a Dmax with 10 quarts bottles of anything before they'd notice the problem. Typically, an oil change place deals in bulk materials. They don't use quart bottles for anything, usually. So, did they fill from a drum? If so, I'd think there would be several customers having the same issues. Do you frequent the shop often enough to know someone honest in there? Perhaps you can get the scoop from the inside?

I would seriously consider getting a sample to Terry Dyson of Dyson Analysis; you can google his site. You're looking at BIG dollars here for a new engine. His kind of expert advice, even though it's expensive (less than $100), would pale in comparison to the cost of a new engine. He's one of the best, and he's often helped diagnose problems like this.

There is a third potential scenario... Someone could have sabotaged your engine, putting something in the oil fill that didn't belong. It seems implausible that you ran the engine for 2800 miles with something so thick that it won't even drain from the pan, so that suggests the problem may be more recent than your oil service. I've seen dozens and dozens of engine failures where engine oil was contaminated with coolant, and never seen this happen. With coolant contamination you will get out of the crankcase a light chocolate, somewhat foamy milkshake that is in all cases I have ever seen, actually thinner than engine oil.

When and how did you first notice this? What is the "fluid level" reading on the dipstick.

I would certainly investigate the possibility of vandalism, and if that is proven to be the case, you might want to consider two things:

1) Police Report
2) File insurance claim

Good luck to you... I hope you get it figured out

Last week Monday I noticed the oil pressure was a little lower than it normally ran. I chked the oil & it was full, but it didn't feel the same as Delo 15-40. This oil was install on 2-16-08. At first I thought the oil pump may be going bad, but with the weight of the oil I thought they put the wrong oil in, say like a 5w something for a gas engine. Saturday morning I took it back to where I had the oil changed at 2500 miles ago. These folks have been servicing our vehicles for some 5 yrs. I told them that I think they put in the wrong oil, they said no that the ticket showed 15-40, I said, I know but it just does not feel right & my oil pressure is jumping around. I asked them to change the oil & the filter again & that I would pay for this change just like any other. A few mins. latter is when they said the engine is all sludged up & the oil will not drain from the pan. Note the engine was hot not cold. I normally keep the truck locked at all times because of what is in it.

Can you post larger pics?

Can you post larger pics?
I'll try but I took these with my cell phone:(

That's definitely not Delo 400. I don't think your truck uses green anti-freeze, it should be the orange Dex-cool. One of the GM- techs on here might give you some better insight. Good luck.

wow the only time ive ever seen something like that was when i took a hazmat tech class. there was this insti gel chemical that you could add to any liquid and it would instantly turn it into a gel...

i would defiantly send a sample into a oil analysis place. that way you have a record of the substance. also keep all paperwork and anything else you can find that deals with the oil change.

good luck.

Bad looking stuff. Another reason I don't trust just anyone changing the oil in my truck. Let us know what happens and the results of the test.

Dnewton: I assume by "gross coolant intrusion" you mean a head gasket, cracked block, cracked head all extreem. I have had a coolant leak but not what I would consider gross, approx 1qt every 250 miles, this has been going on for some time. All "interior" coolant leaks that I have had experence with resulted with a change in amount & color, never a change in form, i.e. color like a milk shake, increase in oil level, etc.. I have never experence anything like this. I have been trying to find the leak/s. I had found a number of smaller leaks. e.g. turbo hoses, injector tubes, cold leak @ wtr. pump. etc. None of these repairs stopped the coolant loss. Compression test passed with flying colors twice. Pressure system pressure test passed 3 times. I was about to chk. the turbo hot when this happened. There were a number of oil changes during this time period & none of them resulted in the oil changing form. I have contacted Dyson & sent him a sample, Thk's for the info.. Also have sent smpls to two other labs. Yes this place does use bulk material. But this time though they pumped it from a barrel not the overhead sys. as normal. I just assumed that system was down for some reason. They used what appeared to be a 2 gal oil pail with the swing spout.

I've seen something like that before. It was in the bottom of the bulk tank that fed the waste oil furnace we had for 9 years. It was about the consistancy of warm mayonaise and had a strange non-petroleum type of smell. Grayish green in color.

Dnewton3 - is a winner :( With (1) lab reporting so far. Dyson is stating Gross Coolant Intrusion. High potassiun & sodium were forund. Good news, min bearing wear is indicated. ;) Still waiting for 3 other labs to report. Will give results. Still do not know what let loose as far as coolant. Hope to be able to repressure the cooling sys. yet this wk. & get coolant in the crank case. What ever small leak that existed at first is no longer small.:eek:

Well, you learn something new every day... Keep us posted

the exact same thing happened to a guy running valvoline blue in his 4bt. The last thing I heard was that he was still waiting on the oil analysis.

http://www.4btswaps.com/forum/showthread.php?t=2894

**Correction**:iamwithst

this was not a 4bt cummins, but was a 4.0 v6 ford gasser running 10w-40 valvoline
my mistake, after 4 years of college I still cant read.:smashfrea

With (3) labs reporting all are calling "Gross Coolant Intursion". I am under the impression "just my country boy mind" that the problem is Dexcool & multi grade oils. You would have thought the makers of Dexcool whould have known this would have been or will be a problem. Has anyone out there seen something like this using "I can't remember the names" the Green or Red coolants. There is one lab left to report but I'm guessing the results will be close to the same as the others. Due the jello like consistincy of the oil I am getting differing metal contents. I can understand this, they are no longer working with oil in the liquid form.

I'm with just about everyone else, all coolant intrusion I have ever seen (more than a few over the years) usually looks like a chocolate milkshake and the oil level is way over full. Look at the bottom of your oil filler cap, if there is no moisture there then I'm not totally buying the gross coolant intrusion theory, but crazier things have happened and I have been wrong before. I have to wonder what chemical/substance the labs are finding the points to coolant? and where/In what else could that particular substance or ingredient be found? Is it possible someone sabatoged you? it just doesn't seem right.

Jesse: I agree with you on never seeing this before. I have seen a lot of coolant in oil & yes it looks like a milk shake. All (3) labs point to High Potassium over 2000 PPM & high sodium as the culprit, I can't remember the sodium numbers & also high moisture content. When I contacted one of the labs, which was Dyson Analysis, their first question was have you had a coolant leak. Denution3 was the first to mention a gross coolant intrusion & potassium contamination as the problem. Dyson was one of the better labs as they e-mail an audio along with the fact sheet to explain what you are looking at & what it means. The only other time I have seen anything close to this was years ago on "OLD" gas engines from the northern part of the country that have sat for years through the freeze/thaw cycles. We are talking about 30s & 40s vintage engines. Again this is a first for me & just about everyone else I talk with. I am going to chk further but as I said eariler I think this has to do with the Dexcool & multi vis. oils.
Thk's for your input.

Well I guess the big question at this point is what are you going to do about it? Coolant in the oil system will destroy the bearings pretty quickly. Are you going to try cleaning it out, or is a complete overhaul in the cards for you?


Keep us posted and good luck with it

You are wright, there is high a metal content. I am not going to take a chance on the old engine & rebuil it. The cost to tear down, cook out, etc, etc, is so close to a new heart that I'm going to have a new heart installed. Yep it's only $$$$ but this is a hell of a lot less than a new truck. And there is not another thing wrong with the 01

Banks is selling Crate LBZ engines... need ECM, Turbo, A/C Compressor.

I wish you the best of luck. Sorry to hear your DMax is down for the count.

Mike, Hopefully if everything goes right, you will be back on the road next week sometime. Maybe you can make the trip up here for our Dyno Day on May 17th.....

Well folks this oil thing is still bugin the, the you know what, out of me. I'm going to do my own test :eek::D. Here it is. It will be a 1/20 scale test. The 01 LB7 would use approx. 1 qt coolant in 230 miles. The oil that turned to jell-o had 2800 miles on it. Thats about 3 weeks of driving. 230 miles of travel takes approx 5 hrs. Which at 1/20 = 15 mins. So here comes the good stuff:rolleyes:. I'm going to set up a dbl boiler on a propane burner fill it with 1/2 qt delo 15/40 & 1.20 qts.dexcool @ 50%. With a 1/2" drill motor hooked to a oil pump & running in solution I'm going to apply the heat. Heat will be applied as needed to attain & maintain 200deg F., going to use the Wife's meat thermometer:D. With the oil pump running, every 15 mins add another 1.20 qts of coolant & keep on trucking until I get to 2800 miles in 3wks. @ 1/20 scale. Just to see what happens :frankenst:uhoh2:. Let me know your thoughts, am I headed in the right direction? I more than likely will not get this done this wk end but next wk end for sure & will post results & photos. :eek:

:cool2:

Anyone know what happens if you put sugar in the crankcase with the oil and run it? Seems like I have heard it will turn the oil into a "jello" like consistency. We had an issue similiar to this on a 350 gasser about 25 years ago, and felt it was probably sabotaged.

Yes I have heard that before also. But the (4) labs I have sent oil smpls to indicate no carbon from sugar only high sodium & potassium from coolant. But get this the oil level has never increased.:think: Also I am sending another smpl to Chevron for them to find out what this stuff really is. None of the labs have told me that this stuff is/was Delo 15/40 to start with. The 1st thing I'll be looking for is a color change to "GREEN" using the "ORANGE" Dexcool:rolleyes:

Well. I don't know if this will help or not. But I do know that If you mix Brake fluid and Power Steering fluid, it will make Jello. and it will be a yellow color. Maybe they put alittle brake fluid in it on accident. Just a thought.

Perhaps the "Jello" had been accumulating in the crankcase for a longer period of time....... say for multiple oil changes. Maybe it took a little time before it could be detected on the stick or elsewhere? Just a thought.

My guess is either an error on the oil changers part, or a problem with the block, maybe a crack in the coolant passages. In any event, best of luck with your outcome! Get an attorney and keep all of the Oil Analysis' for evidence.

Mike mentioned that there was never any pressure in the cooling system. When we pulled the heads off, there was a massive amound of buildup under the valve covers. My guess is that either someone made a small mistake,,,, or the oil cooler is cracked and putting coolant into the oil system. As I tear farther into the motor, I will post more results. Meanwhile got to get Mike his new motor so he can get back on the road.

Well here are a couple of pics from the tear down. Turbo bearings were shot along with other bearings. Cam lobes looked just fine. I have never seen oil turn like this.

Here are a few more. I can't seem to get more than 3 at a time to upload.

More!!

Some MORE!! I figured out how to get more than 3 pics at a time...:coolnana:

I'm sorry, I just don't think that looks like coolant intrusion. Timthecarman, what do you think it is?

What does it feel like?

YUCK! Looks like jello!

That's exactly what it felt like....

Timthecarman:
They started the new LB7 Thursday sounded good at idle but were getting a boost code on increase in rpms. Morris says the motor is more noisy at this time. It seems the code is intermitent. He will call you tomorrow and chat about this. Other wise he said all went quite well. Got any ideas about the boost code?

As soon as Morris calls me I will help them figure it out. The possible noise might be something with the coolant temp sensor. If it isn't reading or unplugged it will mess with the timing and cause the motor to rattle a bit. Shouldn't be a problem.

Did anyone ever figure out what happened? Inquiring minds want to know!

Do you burn WVO or biodiesel?
