Thread: Head bolt sealer

Tweet

What works best for sealing big block head bolts? Last time I used ARPs white sealer and had leaks. Years ago I used Indian head sealer but the new stuff seems to set up quickly. Also, did Chevy big blocks ever use an oil slinger between the lower cam gear and balancer? Some day I might get this 454/496 back together again Thanks Keith

yep the white oil base ARP is crap .i used it on my 572 18 years ago first and last . i use the form a gasket 3 or teflon brush on sealer made by permatex you should not need any oil slinger

Pat, I'm going to use the teflon sealer. Should I torque the ARP bolts to their normal specs or should they be tightened to their moly lube specs?
