Junk yard find update and Lifter questions
--------------------------------------------------------------------------------
Ok, got new cam chain and pads in. cam has good teeth solenoid works. Borescope shows nothing to be conserned about with the cylinders. Goin to start cleaning the top of the head and lifters with head still on car.
now this has sat for 6 years. Head was rebuilt, new lifters valves seals etc. The top of the head is filthy. it was left open for quite a while..The hood was closed but the cover was off. Lifters have surface rust. I poured a quart of oil on top of everything to let it soak up.
Questions.
1. do the lifters pull right out from the top?
2. if so what is the best way to clean them? pull them and let em soak in a solution?
3. is there a test to see if they are still good?
4. I also have a 928. we run into issues with the cam timing gear. does this gear have history of wear?
I am unsure if my gear is new. it is rusty tho. so I am gonna clean it up and put a straight edge across the teeth.. Does anyone know what the dimensions of a new gears teeth are?
thnx
