Hello - My wife's 216 (15300 miles on the clock)! developed a misfire which turned out to be oil in the no 2 plug well which had pushed the plug lead out. The others had oil in as well but not so much. Surprised it ran with everything under oil. I've met this on my K series Rover 75 which has a special sealant spread over the camshaft carrier which leaked. I've searched this site but not found anything - maybe I'm not looking right. Looking in the manual there are o rings under the cam bearing / rocker assembly "posts" which seems to be straightforward to swop. Trouble is I'm not able to find any to buy. Could be I've not got the right name / description and I prefer them to hand before I start. Please can anyone put me in the right direction. Thanks

Have a look at https://rover200.org.uk/forums/topic/15849

Thank you Colonel - I didn't find when searched but I am 70 and grapple with computers!

That link takes you to another thread on our forum about a fix.

Good luck

No sealant on the honda engine. The gaskets are commonly available on eBay just make sure you get one with the four circle plug seals (not just the other gasket)

Hello. I've checked out the links but the engine top cover gasket sets appear to have the four seals that fit the top of the plug holes - ie underneath the cover. They do not seem to be "o" rings or have I got this wrong. I'm after the o rings that fit underneath the rocker shaft mounting posts or is it the same thing? Thanks.

Am resurrecting this as I have same problem with my 416 honda D Series.

What was the outcome?

Remember the aftermarket for Rover is non-existent so look for same part but as a Honda

Well the first part was a doddle. Just got to see about fitting them now. I'm happy doing the more mechanical stuff but engine work does put me off..... but we'll see.

Cheers info and guidance.
