oil galley plugs
Help! I've got a stroked 289 to a 349 high volume oil pump, and leaks. I've sealed the oil plugs on the back of the block with gasket sealer. Two are doing fine, but one keeps leaking at high RPM. Im getting tired of pulling the trans, clutch, and everything else related. What will seal this thing up? I start tearing down Sunday.......again. Thanks

Those are the little threaded ones, like about a 1/8" NPT? Did you replace them with new plugs when you built it? Are you using a good quality USA made plug with no thread flaws? Use non-hardening Permatex, you should have no problems. You're not just gooping sealant over the top of the plug, right?

Thanks for the response. I took out the trany, clutch and related parts. previously the plugs were the problem because one of them wasn't run in far enough. That issue has since been fixed. I found out this particular leak is actually coming from the very corners of the oil pan gasket at the bearing cap. That's a new project. thanks again
