Any update?

I dropped my truck off at this different shop wednesday at 12 pm. For a diagnostic. They said it will be done today (Friday). When they call I will update. Thanks for asking! I have been very impatient waiting, just anxious to know what's wrong.

The shop just called. The manifold gasket is blown. Also the truck is running on 7 cylinders and are running great. Just 1 isn't. He thinks its a piston or a ring. He said he doesn't feel that I need a new engine and he can repair this one. Now unless that 1 cylinder is egg shaped then we have a new issue but he said he just doesn't see that being the case since the other 7 are great. He said it will cost between 1250-1500$ I said go ahead and fix it. Thank you to everyone who has helped me.

It's more than likely one of the rear cylinders that has gone out. I would wager it's either a spark issue or a fuel injector issue on that one cylinder.

Edit: I probably should have put this in a different category. Sorry, admin you can move it where it needs to go.

No, I'm serious. The amount of time and money to lift a truck that much and put Dana 60s in it is impressive.

Agreed.

Ahh thanks yeah the guy said there was some SERIOUS time and $$ involved in the suspension and what not. the transmission is custom with a shift kit as well. First time I have heard of a shift kit and its pretty cool

Could always put it in neutral, **** the front tires, jack the rear up, mark the drive shaft and one tire, spin it and count the rotations on the driveshaft.

*edit*
I just realized we're spamming up the info thread. Whoops.
