Rgvkiwi 10 Report post Posted January 13, 2020 I have bought back my old M3 for the 3rd time.....but it needs a bit of maintenance. Most urgent is a leaking valve cover gasket. BMW have the gasket in tock but not the spark plug seals. Just wondering if you can reuse the existing seals? Quote Share this post Link to post Share on other sites

Rgvkiwi 10 Report post Posted January 13, 2020 Thank you. Is it the case with these that aftermarket aren't really good enough? or are aftermarket suitable? Quote Share this post Link to post Share on other sites

KwS 2425 Report post Posted January 14, 2020 I'd also recommend the rubber seals under the bolts too, if they havent been done. +1 for genuine seals, the Victor Reinz one i got at one point just didn't quite seal as well as the genuine one I also used. 1 Quote Share this post Link to post Share on other sites
Rgvkiwi 10 Report post Posted February 9, 2020 Thank you for all you help. Im wanting to do the SPorts club SPrint at Hampton end of the month so need to get on with this. Anyone have any suggestions on BMW OEM parts suppliers? I know on some car forums there are existing parts discounts available for preffered suppliers etc. Quote Share this post Link to post Share on other sites
