Oil in Spark Plug Well
Had oil in two of my spark plug tubes so I changed the valves covers thinking that was the issue but It’s still filling up with oil. I know some cars have heads that the spark plug tube can be removed and oil sometimes leaks in from under the spark plug. Is this the case ? Any ideas ? Thanks

This is a well-known issue with Z33s. The valve covers have plug gaskets that get torn and leak. Do a search in the maintenance/repair and DIY sections for more details. Bottom line, you'll need new valve covers with fresh gaskets to ensure the leaks are properly addressed.

So common in fact, they have a kit for that. One of the first maintenance items I had to do when I bought the car. OEM 350Z / G35 VQ35DE / HR Valve Cover & Gasket Kit - Z1 Motorsports - Performance OEM and Aftermarket Engineered Parts Global Leader In 300ZX 350Z 370Z G35 G37 Q50 Q60
