Good morning all.
I am having trouble with the filler cap on the cam cover leaking.
i have not yet found the correct three eared cap and so far I have avoided buying the reproduction one.
This cheapo `tin pot` cap has worked very well for ten years but is now leaking.
I have cut a few seals out of various materials but with only short term success.
Can you suggest a source for the correct seal or suggest what material to make one from.
The search facility on this forum is still not working.
I have checked ebay and the local car parts shop and I have oil deflector plate over the No4 cam.
Any advice will be welcome

Eric, I bought replacement seals from QED (part # 103029) https://qedmotorsport.co.uk/product/oil-filler-cap-seal/ but that did not completely solve the issue.

Strange, that did solve the issue for me...


Not my original idea, copied from John Clegg & others...

Feel free to copy the design...

Thanks Phil, I have ordered a couple.

I have gone to silicone on my NA and boosted vehicles.
$2 or £1 because they dont distort like rubber.

Off piste: How long does it take to fill the sump with an oil deftector like that fitted? It's bad enough without.

No difference in my experience. And with the deflector, less frequently adding, as a bonus!

I find the deflector need not be bolted on as it is trapped by the cam cover studs. john

Thankyou Phil, That`s fixed it.
I bought two of the seals you suggested and had to fit both to obtain a satisfactory fit. I assume that was because the cap is rubbish from China. Another leak stopped. OK for now.

Glad to hear Eric
