OK i was making 16 PSI boost no problem with my new setup, tonight on the way home i could only make 13 psi and the engines just not sounding right. Previously i had that woofing noise coming from before the turbo but it went away, still seems to have a miss of some sort, its kinda hard to explain, its just not crisp at the exhaust, like a lazy cylinder (valve? crack?).
Anyways when i got home i decided to pull the hose going into the turbo from the CDR, it seems to be really putting out alot of blow there, even if you put your thumb over it, it seems to pressure up some, also seems to be an excessive amount of oil coming from the CDR, there is virtually no blow from either the oil filler tube or dipstick tube. Valves? Cracked Heads? Any ideas anyone? To me the way i've seen the deteriation over the last 2 or 3 weeks i think somethings going to let go real soon and would like to avoid that if posssible (just cause i hate tow trucks and my truck makes good money when running). I don't think i'll make it another week without blowing something up here. I have never torn down a diesel before but looks like thats what is in the works here and if it comes to that i will be looking here for all the help i can get with this rebuild, so i hope you guys are ready for another hundred questions at that time. The engine itself is only using about 2 liters of oil every 5000 km's with my 8 hrs/day idling which would lead me to think pistons/rings are still pretty good.

Number 5 needs input here. <------- (Its an old movie)

Thanks!

Compression check? You'll know real quick if leaking or cracked cylinders or even a cracked piston are waiting for you and where.

Yes this is true but no time for compression checks at the moment. I was hoping for more of an idication off if i'm looking at the bottom end or top end. Comp test won't really tell me if its top or bottom end will it?If its pistons then nothings going in but 18:1's

NEWS FLASH ! ! ! ! ! ! Compression check reveals all ! ! ! Do not wait - get yours TODAY! ! ! !

Could do a leak down test also. Think you cracked a piston. Pay to play. By the way when you do the tear down pull one of the injectors apart a get us the nozzle tip number.

QM & gmctd suggested compression test.

DieselPro said, and I am also a huge fan of leakdown test. No guesswork here. Just listen for leak.


Are all of your injectors and glow plugs tight? Somebody here had that problem recently.

Remove all the glowplugs, remove the INJ1,2 fuse, Lift Pump fuse, unplug the ESO solenoid - will be easier on the starter motor, won't inject any fuel.

Comp check all cylinders, then leak-down check each - all cylinders should compare max to min within ~25psi, or ~50psi for hi-mileage engine.

Engine will run with ~100psi difference max to min, but is not a condition you would want, in running your 0-60mph time trials.

Looks like a compression test is in order then as soon as time permits. All injectors and plugs were tight at last check but the back 2 plugs behind the downpipe i couldn't see. What's the proper procedure for a leak down test?

Pay to Play? I have no problem with that whatsoever. Time is my killer, every day i take off work costs me a grand.:mad:

Can't you get the '95 and have the wife drive the acclaim?

:joke: :lol: :offtopic:

Thats the plan, once i purchase another phone for work as the one in the 00 is a hard mount.

Amazing how things turn out. Be sure and thank your wife for that. :)

No need to thank her, she has a 90 Astro Van with near 400,000 km's on it that is her daily driver. Body's falling off of it but it doesn't use any oil!

This is probably a stupid question but did you check the air filter?
I hit a bird once and the airbox got packed full of feathers.
What about bad fuel?

I did hit a prairie chicken a couple of weeks ago, broke my damn grill too, had to pick that sucker out from behind the grill the day after... ewwww. Air box has been off lots since then, don't think its bad fuel as the problem has been slowly creeping up on me, no codes or nothing, seems to be going down on power rather rapidly now from day to day. I'm keeping the camera handy, never know what might happen.

What about the fuel supply? Is the lift pump dead or getting weak?

Just checked the lift pump as it was a possibility after reading your post. I have 5 psi at idle, punching it hard it barely drops to 4 psi, haven't checked it under load but it should be acting just fine according to that.

Any real good diesel mechanics on here that live reasonably close to me?

Do you always buy fuel at the same station?

Usually get fuel in the same place, but i do get fuel from other places, always someone that sells in bulk, i also run conditioner, never had the WIF light except when i washed the engine. Like i said before this problem has been gradually sneaking up, if it were say a cracked piston shouldn't i be getting a code for cylinder imbalance or something? I'm beginning to wonder if a couple of cylinders are having a little chit chat with each other.

Hopefully not conspiring against you!

A cracked piston - or two, or three - would result in increased blowby out the dipstick, oil filler tube, CDR, or any where else you could 'unplug' to check it, with a lot more raw oil in the turbo inlet............

Do the compression test, a small crack in a piston will show up first as a loss of full compression. Keep running it and you could have junks of metal flying around. Also, check for bubbles in coolant, they usually indicate a blown head gasket, and sometimes tiny bubbles will warn you of a head gasket that is getting ready to let go.:eek:

CDR is the only place there's lots of blow, 0 blow at dipstick or filler neck. I've lost 4 -5 psi boost WOT and 2 PSI cruising.

Worth checking-- I picked up a couple psi of boost when I replaced the doughnut gaskets on my crossover pipe. Just take a look around the flanges, it is obvious if they're leaking as there will be soot around and on the flanges. Like I said, Its worth checking. Wish I could help more.

Althought that is true it wouldn't produce a miss like i have, just the woofing. Nor would it increase the blow from my CDR if the gasket was on its way south.

I have created a small video file of my engine woofing as heard from the exhaust pipe, anyone want a listen?

PM me so i can email it to you.

Its only 128kb in size.
