metal shavings in timing cover
I didn't use a case harden bolt when I pulled out the pin in the chain rail retainer. I had to tap it out and got some metal shavings down the timing chain case. Also a few plastic chips off of the retainer.
I was going to flush it out with carb cleaner or kerosene and drain the oil. then blow it out with compressed air.
Pulling off the whole front end isn't really an option since I don't have all those pulling tools.
P.S. Head took a while, but came off OK
