The driver side rear lower head bolt on my car keeps leaking coolant. I always put ARP thread sealant on all the bolts, but recently when I changed the cam I tried pulling the one bolt out and resealing it again. After a few days, the leak is now much worse. The car runs great and has no coolant in the oil. The current block has maybe 10K on it because I got a refreshed level 10 bare block from DSS. However, the seepage issue was a problem on my old block as well so a block issue is pretty much ruled out. Are the AFR heads maybe warped somehow? Last time I had them checked out they certainly didn't mention anything. Anyways, I'm trying to figure out what to do at this point. Should I try throwing a new head gasket on that side and hope it works or maybe try torquing the whole head down five more pounds? Any suggestions would be great, thanks.
