Hi, had the spark plug tube o-rings replaced by a mechanic because oil was in each spark plug tube cylinder. After the repair, there is still oil in the spark plug tubes. I know some videos online that sealant is used in addition to the o-rings to stop the leaks, but Eric the Car Guy says not to use sealant, that it can clog the oil passages and that the o-ring is specifically designed for that particular application by itself. Any ideas on how the oil is still getting past the o-rings or how to fix? Thanks.

It could be improper valvecover gasket torque, it could be a defective gasket, it could be the mechanic billed you for parts he didn't buy or install.

ETCG probably recommends no RTV because most people don't give it enough time to cure, and use way too much. If you can wait 24hrs for it to fully cure, I see nothing wrong with putting a light skin of RTV on the spark tube seals. That said, when I did my VC gasket I only applied RTV on the corners of the gasket and have only negligible weeping in the spark tube seals.

I remember when these cars were fairly new and they had a light coat of Honda bond on the tube seal.
