pulled the spool valve out last night, no debris in it. once it was back together I activated the solenoid. in doing so it buzzed/slapped for about 0.125-0.25 seconds as it changed the timing. total timing change took about 0.5-0.75 seconds.
is this just a low oil pressure issue? I found an article from vw now that says minimum is 1.2-1.7bar/17.4-24.65psi. I thought minimum was right about 14 psi at hot idle?
I am running 0-40 fs mobile1 and at cold start 70* day op is north of 60psi idle. hot running 4krpm its bout 60psi. hot 2krpm Im close to 40 psi.

I am also starting to question the temperature (considering what was left of the seal) of the oil but I don't have a good way other than an external probe taped to the cct to check it atm.
