+1 for the M44 timing case conversion. The 1994-1995 M42 timing case also has the updated guide which replaces the (awful) deflector sprocket. The M44 case differs in that the oil pump rotor is 11mm thick instead of 9mm thick (or something to that effect) so it can provide a higher volume of flow. However, it has no provision for holding the crank position sensor, so you will need a machined adapter. Metric mechanic sells one, I think.

Yup NLA from pelican just got the email, I was hoping it was the other part number posted at the beginning of this thread they had said was out of stock. Guess they leave the part listed just to mess with us ahah.
Just out of curiosity has anyone actually had a chain skip teeth or other timing issues due to just the cam sprockets being worn, and not due to a worn tensioner, chain, and/or guide being the real problem? My pulleys are pretty sharp looking but the tips are all oil varnish, no wear has happened there in a long time, as in the chain doesn't make contact with the top 1/3 of the sprocket teeth, making me wonder how it could have worn down so much or if the wear stops once it gets to a certain point? Obviously they are NLA so i'm going to have to run it as-is anyhow but it seems unlikely a properly tensioned double row chain would skip teeth on what is still left of the sprocket.Last edited by J0dylan; 01-11-2018, 09:42 PM.
