Really need some advice on my troubles, techs please.

Friday I went and had my oil changed at the place that does all my vehicles and just about every other diesel in town. When I left I noticed a stutterin/vibration on acceleration. Took it back and found out it was nothing that he could have done. We thought it was water, but after inspectiong the fuel we ruled that out. Saw a little garbage in the fuel and changed the fuel filters. No improvment and no more garbage. Also after the truck is hot and I let it sit for 2-3 hours and start it up a lot of white smoke pours out. If it sits until the engine is cold again, it does not smoke. Took it into the dealership today. They found a few small problems on the truck such as leaking de-gas tank, dirty egr valve, reflash pcm. When it came to my problem they had no problem recreating it, but could find nothing wrong. They said 1 likely culprit was a bad Torque Converter, but no way to test that without pulling the tranny. I don't know what to do because they had 2 techs on it(I have full confidence in these techs, until now, this dealership is just unreal at how great they are usually.) and basically the final diagnosis is..... run it until it finally breaks and then we will know what is wrong. I tow a 13k pound trailer and don't want the TC going out on a trip. anyone have any ideas?

not sure if it would help, but I can pm a VIN number if you are a tech and need to read the OASIS(not sure if it will have useful info)

What year model and how many miles? Have you had the tranny serviced on schedule?

Ok, took it to 4 different shops, AAMCO said Ford TC's are crap and I should replace it anyway and they will do it for $700. Went to Mercury dealer in town that does Ford Diesel service and they said leave it overnight to do "cold tests" in the morning, didn't want to leave it. Called a buddy mechanic and he gave me the name to a guy who owns a tranny shop and he is awesome!!!! He drove it, and said there is NO WAY that vibration is from the TC. He said the TC would have started leaking by now if it was that bad. Hooked up the Snap-On Modis and it threw no codes. On the way back to work I stopped by another Ford Dealer that I have heard good things about. The diesel tech came out, started the truck up and said "it's the engine, this just isn't normal." He pulled the oil fill cap and there was some blow back he said wasn't supposed to be there and could mean head gasket. Looked down and said it looks like the damper was wobbling a little and that could also be the cause. This guy was awesome and actually knew what he was doing. He was just pulling a 7.3 to replace so he won't get to my truck until Tuesday. Guess we will find out what is wrong on Tuesday when I get the truck back to him.

Yeah well that guy is an idiot, blow BY isn't caused by head gaskets. That would be the last place you would see blow by.

You can go to any dealer start a new 6.0 and will see a small amount of smoke out the filler cap, anything more than what a ciggarett would admit is excessive.


The dampner possibly, if this is the case upgrade to a aftermarket dampner.

If he tries to get a head job out of this get a 2nd opinion, are you losing coolant? do you smell Coolant?

there was quite a bit of smoke coming from the filler cap. not sure he said if he said that is what caused him to think head gasket. this is all new to me so I was just trying to understand what he meant and could have gotten that wrong. I was told this guy is one of the top 5 ford diesel techs in the nation, but I know a lot of people claim that. I am likely to believe it because I wasn't told by him, it was from the owner of the dealer whom I have faith in as he is a very good guy in town.

the last dealer replaced the degas tank and i have no coolant leaking.
