I made 2 passes at Expo with my new Lincoln power plant On second pass i smelled oil, and at the turnout noticed oil smoke billowing from #6 zoomie tube.. A check of the cylinder in the pits revealed lots of oil in the cylinder.. Upon pulling the head it was obvious what caused the problem. Upon replacing the gasket I used the Mummert trick of removing the section of the gasket that covers the pushrod chamber in hopes to get a better clamp load.. I also gave the ARP studs an extra dose of torque till they were screaming for mercy We shall see if it holds.. Lincolns are notorious for blowing gaskets

Bad luck Royce! At least you know whats wrong and it could have been much worse. Robi is putting ridiculous torque on the 7/16" studs in his turbo engine and it doesn't seem to hurt the studs. Seems to keep head gaskets in now.Let us know what you pick for a cam in the 333 Y

Sure looked a lot worse when you pulled back into the pits RB, glad to hear a gasket was the problem.

Royce. Glad it’s an easily fixed problem. Would ½” head bolts and an increase in head bolt torque be a possible fix? John’s mention of more torque on 7/16” head studs is also a possibility but I’ll typically go with a larger stud diameter when more torque is required whether it is a stud or a bolt. With the engine already together, the choices do become more limited.

The Lincolns use 1/2 inch head bolts. I torqued them down to 130 ft lb so we will see how that works
