Ok... So, I did a HG for a friend a couple months ago. Instead of having the head milled etc I put one on from a known running motor. I pulled it off in the right order, put it on in the right order with ARP's. Its a Felpro composite gasket.
The friend was in SUCH a hurry to get the car going. And not exactly the easiest on cars. I got it running, just so happens he was at the house, we let it get warm everything seemed normal. We did not do a compression test etc, he was just supposed to drive it home, put it thru a heat cycle and drive it back in the morning when we could go over everything. What does he do? A 7k launch in front of my house at 1am and banged gears all the way down the road. He blew off a i/c pipe and my other friend who was following him happened to be able to help him get it back on at the corner gas station. Then what does he do? Rips out of the gas station again, tried racing my friend all the way home etc.
So, he's very hard on cars even tho I told him to just limp it home basically.
Tonight he brought it over because it has been overheating etc. His fan does not turn on so I think that is another big problem .
I had him leave it at my house for the night. I did a compression test it went 110, 90, 45, 90 I tried putting some oil in the cylinders to see if the rings would seal up or what. After a little oil it went 120, 120, 110, 122. I'm now confused because when I run the car there is other conflicting things going on to me. Such as when its not heated up there are no bubbles in the coolant with the cap off. But once up to temp there are bubbles like a blown HG. Once its slightly over temp it literally blows the coolant out the cap hole.
I'm going to assume that the HG is blown at this time but.....
I'm trying to determine if I have any fault in this situation? The car seemed to run fine when I was done with the 1st HG job, we let it warm up for a very long time, had no issues with getting hot etc. I'm thinking the abuse the car took extremely shortly after the HG was done has contributed to the current failure, or the fact that the fan is not working. How do I move forward? He's not a close friend, but he is a close friend to another friend I have and he is local. I really dont want to build any ill will or bad name for myself as it only takes one loud mouth to ruin a reputation.
Also, he has said he had to drive it a little while when it was very hot. I'm thinking the rings might be washed out from the heat causing the low compression numbers. Also, if the HG is blown now, how can it still build 120psi compression? (I know that is below service limits).
Sorry for the stupid long post. Any help is appreciated.
