uhhhh... idk I bought from a guy in bellingham, years ago, said it needed to be rebuilt.
In my shed it sat until finally the 1.5 on the freeway.. .kerplowy.
So what did I do, had to put it in did minor gaskets, drove her hard
probably put a good... id say 75000 on it since. Finally did valve seals two years ago,
Present day, would go thru a quart every 4 days or so... for the last year or so. i'd only add oil when my oil light would come on
got burned on the two motors. one had spun rod bearing.... bad.. black ring lol
second one, came with dizzy manifold harness, full long block... said it " may " have popped a head
got it home, took the head off in 30 minutes. top looked good, I have pictures somewhere.
thought ya okay this will be okay to slap the rings and bearings in...
ehhh wrong, cracked piston ring gland in one piston. and the bearings were chewed...
WELL I figured, meh my motor in my car doesn't knock or leak or whatever.
So I rebuilt it. rings bearings gaskets hone.
block came pretty clean.... head I didn't really clean, just the surface and brake cleaner and a pressure washer.... didn't go all out on it. I wanted it together.
The z6 head I have is in great shape and the plan is to put it on asap. Which SHOULD be next weekend.
