Title: Oil passages
Post by: Wrenchpuller on July 22, 2026, 04:58:57 PM

Hi all,

Currently stripping my engine to do all the seals etc. Just a question on the top oil passage behind the oil filter, is it supposed to look like that?

Picture attached
Many thanks

Yes, that's how they are. Well, the drill hole looks correct.

Hello! Thank you very much! I've read the odd bit on this forum since getting a 400 about a month ago, thought id finally make an account! I'll save the rest for the introductions section when I get around to it  ;)
