Cracked head (intake) but 2 different stories from 2 different mechanics !

Liners shimmed 30 thou over spec???????

That's ####ed. You're asking for a cracked head and blown gasket with that setup.

 

Liner protrusion should be set somewhere in the ballpark of around 3 to 5 thou (depending on the engine). 30+ thou is way too high.

You're it!

 

Basically the Mechanics saying, he cut the counter bores and shimmed 2 liners, to bring the heights up to spec. Normal stuff. Sounds like a decent Truck, if they’ll stand behind the warranty and make it right. You’re going to lose any money spent at another Mechanic.As far as the other small things go, that’s what you can expect when buying a Truck unseen. You bought it anyways already, after seeing it. The high oil pressure is not right. I wonder if a blown compressor head gasket could also be causing that. You’ll need to get to the bottom of it. At this point, the best you can hope for is their cooperation. I’d be slow to make any accusations, since you really don’t know the problem yet.Its probably cheaper at this point to work with the original Mechanic and Seller. Burning that bridge, even if you win in the end will cost you a lot more. Give them the benefit of a doubt. It’s easy to guess at the problem, whatever it is, it can be fixed.

 

I know of another CAT owner that had high oil pressure at idle - and the problem was a sticking Oil Pressure Relief Valve.

Uhhh...did you even take the time to read this thread?
Truck was sold as is no warranty.
Warranty would only apply to work performed but he can’t take the truck back

 

Some dealers mechanics (mechanic A) invoice the dealership for work done to trucks for sale. As stated in first post. 6 months warranty left.

That is how I understood the post.
Have a good day.
