Finally I need some help from all of you with heads and cam. My shop is having a hard time with the install. The Jeep has been torn down for almost a month now. Here is the break down.
Tear down went fine, flow test had some impressive numbers.
Reinstall Not so good. I get a call telling me the valve to piston clearance was almost non, and the cam was the problem. We called and got a new cam to test. Same problem with this one. So now they start testing the head.
In testing the head vs the factory head it seems it has a good amount of clearance with factory not so much with the P&P heads. So it seem that the mill is wrong but they all specs seem to check out per the porter and my shop.
So my question is, did anyone run into something weird while doing these?
Did your install shop test clearance?
My first thought was the cam timing, but now I have no clue.
I would like to PROP up the DR, Franks Racing, they have been overly helpful trying to resolve this over the phone. Franks Racing shipped a cam right out for us to test to insure it was not the wrong one.
Matt at DR, is confident that the heads were not milled and is willing to help however he can. He would like to see both his heads and mine for comparison. But this puts the Jeep down longer.
My next step is to ask you guys first, then test a thicker head gasket, then send the heads back if needed.
I HATE THIS!!! (insert smiley with tears)
