I belive it is the 61X.xx engine It's a 300t '82 the Odo reads 129k (but I suspect it might have been turned at the shady car lot I bought it from...)
I decided to set the vavles and button her up and do the work after another few thousand miles or so (the end of summer.) Teh sprocket looks good and for the most part, everything "seems" really tight in there...) the rest of the car has some issues that need fixed first and I suspect my transmition Still I've just read through three service manuals about the procedure and it doesn't seem "to" hard to change... A little grinding and a feed through the gears withthe wire "trick" ...(almost like an old bike chain removal) Almost wondering if I should do it while I have everything open and in the garage.... Wondering if it will make THAT dramatic of a improvment... but I don't want the thing flying apart on the road either. I hear that pretty much kills the engine... and thisis the one thing you want to keepup on on these old engines...
