Valve gaskets leaking woes, Won't stop Options

[Wew]

Hi all,

I rebuilt my 1973 2.0 motor, which was already a 2056. I put new 2.0 heads on it with 1.7 rockers. Was machined for spirited driving.
I put the bigger 914 cork gaskets on as well.
They still leak. The straps for each valve cover are tight.
Any advice, tips and or tricks to end this valve cover leaking madness?
Not sure it increase pressure due to no vacuum port on the new heads has anything to do with it, but either way, I gotta figure out how to make it stop.
Please advise.

Thanks,

Gary

I had one with a slight bend that would not stop leaking. I replaced it with one from a spare engine and no more leaks. Also, make sure the crankcase vented adequately. Otherwise I've found glueing the cork to the valve cover and putting some grease on the cork where it seals to the head works the best. The grease helps the cork slide on the head without coming loose while you adjust the bale.

Hi Michael,

I purchased the air cleaner and oil filler for a 1975 model.
This was supposed to help with ventilation since the new heads are not vented.
It's quite a large line coming off the oil filler (i think 20mm) which ties into the air cleaner cover.

When you say the crankcase vented adequately, could you please elaborate on that?

Many thanks,
