Hello all!

Had a race this past Friday night and, for the second time, the oil pan gasket blew out right behind the oil filter. This happened the first time a week earlier. Found out the bolts close to the oil filter were loose so I replaced the gasket, added some RTV and made sure to properly torque all the pan bolts. However the gasket blew out again.

Has anyone else had this problem?

The engine crank case is still vented and not clogged. The oil pressure, based on my gauge, is about 35-40 psi at WOT.

planning on taking the pan and block down to nothing and having them resurfaced flat so they mate together well. However if there is a simpler solution, I'm all ears!

I know a guy who had this issue with Vanguard's. His engine plate/ frame was twisting. Welding some flat stock around the underside and drilling the mount holes through it corrected it in his case.

For the sumps that use a gasket I use the rigid silicone around the o ring area. regular silicone just wont work. also torque sump bolts  down and then loosen up and retorque. I would recommend a little blue Loctite on bolts with retorque.
