Hey guys been a while but i have yet another problem im wondering if i can get some help on.
In march of 2018 i decided to change the head gasket valve stem seals and all upper gaskets. The truck has not moved since first tearing into it and now its near a year later and no progress still after multiple times trying to fix it and im at wits end.
Ever since busting the original seals i have not been able to keep the intake from leaking. The head was torqued in sequence at different torques until reaching spec. The head gasket is on the correct orientation as well so i dont believe thats my problem. Now this is my 4th time reassembling the intake and the 3rd head gasket ive put on and it still leaks.
The head and intake were all taken to the machine shop so i know they are all flat. The head has been surfaced as well as the mounting surface for the intake. All 3 pieces of the intake manifold have been surfaced at their mating surfaces. Its leaking where the head and intake meet as well as where the lower and middle of the intake meet. Im using felpro gasket kit PN: MS 92964-3 and felpro head gasket PN:9388 PT.
What do you guys think my problem here is??? I will be taking it all the way back down to see the cylinder walls again since the last time it sat for months and now i can see rust and what looks like crystallized antifreeze in cylinder #4. It just doesnt make sense to me that it leaks in the same spot 4 times even with another intake and after having everything sent to the machine shop.
Any advice will be very much appreciated im almost ready to just tow it somewhere and let them deal with it but ive always worked on my own things and even though i run into problems i figure it out or you guys help me along the way just wanted to check in here before spending unnecessary money.
Thanks in advance
Thomas.
