Does anyone know where I can find a set of MG logo valve covers? Olds 215 with Buick 300 heads. Roller rockers

David, If you mean oem., as in MGB GT V8, I suspect they will NOT clear roller rockers. Might be better to use taller after market, and add logo ? What does" Yella Terra" say ? Good Luck, roverman.

Thanks Art
Thought about that and will have spacers cut by semi Local with a new waterjet toy. He has fabed the rover/bop head boring plate and it's a beauty. I like the finned MG logo. Venting? Tall rover valve covers look like they would work?

Carl has the MG covers. He's been having an issue with blowby pressurizing the seals. IIRC there is just 1 threaded port in each valve cover, 1/4" I believe. Certainly not big enough to properly vent the engine, even the old road tubes were at least a 1" diameter but usually larger, so they can only handle something like 1/16th of the flow at the same pressure. Meaning of course that you'll need to increase the venting somehow. I think there is a second boss on each cover but a better choice is probably to use the fuel pump block off plate for a 3/4" vent line.

Jim
