Hi Guys:
I thought the following would provide good data on a variety of fronts. First, the facts.
As most of you know, my truck had an injector problem at 14,400 miles. Injector #1 stuck open. As part of the repair, I asked for fuel and oil samples, which were provided.
Yesterday I received from AV 3 oil analysis kits and 1 fuel analysis kit.
The fuel sample taken was from the fuel in the tank when the injector gave. It was taken from the out line post OEM fuel filter. The truck has a pre-OEM Nicktane (large CAT filter) as well. Both the CAT and OEM fuel filter were changed at 13,500 miles, so only 900 miles on both units at time of injector failure, and the sample taken after going through both. There was a half-tank remaining in the truck. One notable fact: I did not have the sample bottle available when the repair was done. The sample was captured and provided in a 12-oz. Arrowhead water bottle. After receiving the kit, I simply opened the AV bottle, poured in the fuel, and closed it fast. What and how much of an effect the capturing method will have we'll just have to see.
The first oil sample was of the oil in the crankcase when the injector gave. It had less than 150 miles on it. When I checked the oil while waiting for the tow truck, it was clear, yellow, no soot, the right level, and no smell of diesel. After the repair, when I went to deliver the oil for them to put in the crankcase, the dipstick showed very sooty oil, and smelled of diesel. They obviously ran it some. Delo 400, Baldwin 1440s are the components. Another caveat: They didn't have a sample bottle. The sample was provided in a 16-oz glass juice bottle. Same comments as above as to sampling.
The second oil sample I sent out was of oil dropped at 15511, 1007 miles on it, consisting of a 600-mile round-tripper to Vegas, and the rest a mix of city and highway. I wanted to get any diesel residue out of the crankcase, plus check for any problems. It was sooty. I'm hoping fuel-in-oil levels here are very low. Another caveat: No sample bottle available. The sample was given to me in a STP fuel-injector cleaner bottle. http://www.dieselplace.com/forum/smileys/Disapprove.gif
The last sample will be taken at my next drop, at 2500 miles, in as sterile conditions as I can swing, and I'm really looking for this sample to indicate all is well and good.
As a point of order, I have had a UNI installed since well before these samples were ever put in the truck, so aside from the potentially non-sterile sampling techniques, we might get a good indicator of how the Uni is working in my engine.
I'm also hoping to see good fuel results as to Nicktane, sampling technique be damned.
I've asked on all paperwork that George be informed.
Cross your fingers for me, guys.
