Spitting oil through tailpipes.

Hey Mike. Sorry to see a post of woe. But glad to see you here. I’m with Ramm & moper on this.
Have you kept an eye on the dip sticks oil level consistently?

The only place I can see oil getting out is the exhaust valve seal. But it would have to be a super heavy leak. If everything else is sealed well, that’s the only exit. I’d start with removing the header first to see if it is bathed in oil. Can you remove a spring on the head installed in the car?

I hate mysteries like this. Drives me nuts.
