bit of an usual one guys but here goes....
So I have a R34 Rb25DET Neo with Tomei spec 2 cams, cometic triple layer head gasket, ARP head studs, high, mount, greddy plenum, pfc usual kind of stuff everyone has now days...
I was driving it yesterday down the fwy, when I pulled off the fwy I noticed my temp was at 106, I wasn't far from my mates house so I kept driving to his house, keeping an eye on the temp and it wasn't increasing as I was moving, I know this is still bad.... Anyway as im just about to pull into his street I notice my oil temp is almost maxed out on my temp gauge. So I shut the motor down and let it cool.
We found the cause of why the car got hot, simple coolant leak under plenum, repaired leaked, refilled with water, rebleed system and all seems fine now. The problem I am concerned about is now when it idles it seems to be a lot lumpier then it ever was before with the cams. I drove the car about 40km home, cracked gate a few times and all seems to be as normal.
I am wondering now if maybe serious damage has been done inside the motor after heating it so much? I am doing to dump all oil and water this week and change out the plugs, prob do a compression test also just to make sure all is OK.
Any ideas? anyone heard of this before? Should I check anything else?
