Today was a service day. Oil change and valve adjust and recheck the torque on the rocker shafts I redid a number of months ago. All good there.
Last weekend while on the group drive they guy behind comment my car was smoking on decel sometimes. So while I had it on the lift and opened up I also ran a leakdown test. All was good with no cylinder lower than 97%. So rings are good. I likely have some tired valve guides. Just going to live with it for now.
I pulled the heat exchangers to check the new gaskets I put in a few months ago as I’m still getting some small backfired that seam to indicate an exhaust leak. Sure enough there was pretty clear evidence of leaks on three of them.
So I went ahead and replaced my exhaust seal rings to see if they might be the culprit. Here are the new rings in place ready for headers and gaskets.
We’ll see if this gets its all sealed up finally.
