Rover 200 & 400 Owners Club

Hello. Please can anyone help? I've oil collecting in spark plug holes - about half an inch every 500 miles. Not all fill up equally. I renewed the rocker pillar o rings at their bases and also the seals in the rocker cover to no effect. Could it be the PCV value and if so where is it and does anyone have a part number or advise where to get one? Thank you.

I have similar issue and have also replaced the lower o ring seals and checked the top seals and it still happens - car does not burn oil or lose oil but it does collect around the plug bases. Not found a cure but just take out each plug and get rid of the oil and run on every so often. Seems to work but the oil does come back and so the cycle repeats.

There's another post on here from June 23 which deals with this plus..... embedded within that thread is a link to a previous post on the same topic.

Apologies but I can't attach a link.

I did replace the seals on mine and it worked however, I've probably done less than 100 miles since so maybe its too early to say.

Yes.... and yes, you're right, same original poster. Apologies for not joining the dots

Hello. last possibility could be the pcv valve. Any one know where it is and a part number?
