    Reman engine no start than start with detonation.

    So I changed my engine. I had a misfire at first. Got that figured out. Had a knock sensor code that zi clear it. (Do you torque your sensor? I did, even the old engine had same issue. Installed new sensors). Any way issue is that it starts cold just fine. When hot it will crank no...

One time I took a old chevy pick up for ac work and they did $400 dollars work to it and it worked for a week. when i took the truck back they replaced the compressor for free because they give you 30 dsys warranty. Ither time i took my Prius to Toyota dealership...

    2006 Tahoe-White smoke on start up

    It appears to be working. And this is why it didn't work just cleaning the old one. I think i sprayed 20 cans of advance auto carb cleaner bottles in there and there still was stuff there to clog the litter drain hole right under the nipple for the hose. Just wish I could get the $408 back...

    2006 Tahoe-White smoke on start up

    I did get the oil out Saturday, it was good until Tuesday when the smoke came back. Since then i have installed the oil catch cans and smoke went away. Today I installed the new cover and the catch can catch very little, maybe just the residue from the hose. I think that is the fix. Will...

    This is 32 miles of driving and i think that this is just the residue from the house. I think my problem has been solved with the $140 part from Amazon. Thanks for all your input.

    2006 Tahoe-White smoke on start up

    Well. I looked inside the cylinder with a camera and found that oil is coming from the top of head somewhere. Hard to tell but top of cylinder head is wet and you can see oil at the head gasket area. I think if i redo my heads and the gasket that will solve my problem

    What about the oil in intake problems with the ls engine. I got the borescope today and looked down my intake and there is a pool of oil in there. What do you guys think about cleaning out the intake and installing oil catch cans. Cuz I'm thinking that the car is only 95% of times it only...

    2006 Tahoe-White smoke on start up

    What do you guys think about this. If the oil is getting in the cylinder on start up that would mean that when car is shot off the cylinder should stay dry untill start up at which point oil gets past the rings untill it gets hit and seals again. So I just got a borescope from amazon. So if i...

    2006 Tahoe-White smoke on start up

    It dosent make sense, with all the smoke i get on start up. It got to drip down from heads cuz when you shot off the engine the oil cant just drip up in to the cylinder. Should i gamble on the heads and change them?

    2006 Tahoe-White smoke on start up

    The mechanic was saying that the oil ring may be gummed up and sticking to piston and some how that makes the oil go by in start up. But as soon as it gets warm it starts working as it should. I was waching some videos on YouTube about soking the pistons in trans fluid, or injector cleaner or...
