1999 C70, Klaus suggested I repost for answer.

Does anyone know how deep the bottom hole in the block where the pcv system plugs in should be?

When I performed the flame trap replacement. I put a screwdriver in hole to check if it was plugged. There were no oily deposits or gunk around the system and the screwdriver went in only about an inch and hit something hard. Sounding like metal.

I assumed that the hole was not that deep and I hit some type of baffle and didn' pursue any further digging. Is this correct or did I just hit a very hardened oil mass that needs to be drilled out?


Previous post----I preformed the flame trap replacement with a kit from IPD (2E8705 Complete PCV Kit). All went smooth and all hoses in the correct place. The car runs fine but I am still getting alot of oil leaking out the filler cap and the PCV hose that connects to the top of the head where the spark plugs are keeps blowing off. (new oil cap gasket installed to). It appears there is a hard block somewhere but I don't know where it could be. The square hold in the PTC valve was also cleaned but it didn't look like there were any deposits. I am at a loss for the answer here. Any help would be appreciated.
