Some lessons learned!
Bought an 87 Shelby Z a few months back. Had to give it some TLC, but overall is an awesome car. Been driving it for about a month and noticed an exhaust leak, found it was blowing at the clamps at the front and back of the cat. Welded it up only to also realized it was leaking at the exhaust manifold. Oh yea, fun job coming up.
I pulled the head, had all the part for 87. Installed new HG, intake/exhaust gasket, new flange gasket, put head on, went to set up new timing belt, when I realized the belt didn't seem to fit right as well as grooves wore in on the aluminum crank seal housing from the old belt. I take a closer look and notice I'm installing a new 87 square tooth timing belt, but all the sprockets are round tooth.. what the heck again..
So after much research and trial and error, I learned:
- 89 2.2's was first year crank shaft was 1inch, round tool crank shaft sprockets are 1"
- 84-88 2.2 were square tooth, .900" crank and crank sprocket. so couldn't shift to a square tooth allthough I tried as I was able to get the square sprockets easily and not have to buy a belt.
- 84-88 2.2 timing tenioners are shorter on the backside, 89 2.2 timing tensioners are a bit longer and pulled the timing belt out about 1/8" from the block farther than the 84-87 tensioners. I had a 87 timing gear tensioner on it initially when I bought it which is why the belt was rubbing the crankshaft aluminum seal housing. Got the 89 tensioner, 89 round tooth belt, and
Walaaa. up and running w/o any timing belt rub any more, as well as all exhaust leaks fixed.
So I have an 87 head w/ two piece intake and garrett turbo sitting on top of an 89 common block.. hoo yah.. Just wish I noticed that when I bought the car, would have made this job so much faster to complete!
Lesson Learned! Gotta know what you "REALLY" have, before you start working on it.. LMAO... :thumbsup:
