Hi Graham, Since you're going to pull the heads off anyway (right?), before reassembly I recommend getting a set of ARP head bolts (if you don't already have them) and a tube of their thread sealer (part #100-9904) for the head bolts that protrude into the water jacket and the intake manifold bolts. The nice thing about the thread sealer is that in addition to sealing the threads it is an excellent lubricant to ensure more accurate torque readings. I've used ARP's thread sealer and their assembly lube (part #100-9903) on the last five engines I've built and haven't had a problem with any of them.

I know you'll have to throw away some new head and intake gaskets but whats $50 compared to what an engine costs Torque all bolts In the right sequence to half spec'd and take a coffee break, then torque to full spec and then start the engine, run it for a while and retorque once more ciao Med Vennlig Hilsen/Kind Regards/Cordiali Saluti Andr� Broe Jensen -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Graham Wooden Sent: 11. januar 2004 00:39 To: 'The Chevelle Mailing List' Subject: RE: [Chevelle-list] Wow - Engine runs but leaks from head gasket :^( They are the cheap Felpro set. I believe I torqued them to specs, which now makes me believe that I didn't. At any rate, I am about to go through them again and re-check.

Could be the head bolts weren't torque properly originally or possibly sitting with only air temp warming and cooling, they may have loosened up. Dale McIntosh I've stopped 98 spam messages.
