Part identification

[alterastro]

Me again! :-)

Can somebody identify this part for me? It sits on the top rear of my 2.8 and is leaking oil so me thinks it needs a new gasket but I dunno what it is!

Cheers

I got nothing ... anyone else help here??

Does it sit near or on the rocker cover? could be some kind of crankcase breather valve.

Yes it's sort of cut into the rocker cover at the rear nearest the bulkhead

It's ya vacuum pump for the brake booster.
The later rd28's run one instead of the typical one on the back of the alternator it runs of the cam.

Thanks. Is it just a case of undoing the bolts, lifting it off and replacing the gasket or is it more involved do you know?

Yeah pretty straight forward .
