Hey Steve,

I have been using 20-50 fleet oil (purple lable - too lazy to go check)changing every 3K miles or so...getting very good results.

I had a leak around the top of the primary fuel filter...only thing that stopped it was a new copper washer...nearly drove me crazy...have to change every time I change filters or ot will leak again!

Problem:

I have an 83 300D...tach operates intermittantly...I can't seem to find how it is connected to the engine...suspect a loose connection...any ideas?

Mike
