Replacement oil cap

[krappy]

Recently I got a replacement oil cap for my Ph2 172 - Part No 8200062947 - but it doesn't seem to fit

The diameter of the cap is slightly larger than the original cap and means that the side of the inlet manifold runner interferes with it, and I physically can't secure down onto the engine.

It's a genuine cap from Renault too, same as what you can buy on the KAM Racing website - looks a little bit different to the original one:

Has anyone else experienced this? Short of grinding down the inlet runner or the cap itself I don't see how it can fit...

Just to follow up on this I had to file away some of the inlet runner - not a huge amount though as I also shaved down the cap itself a bit to make sure it had clearance to fit.

No biggie in the end but a bit disappointing that it required a bit of fettling to fit - posted as I was wondering if anyone had experienced this as well. I assume through the lack of replies that no one else had... 😅
