The spring is there mainly to put the proper tension on the belt during installation and as long as it's properly tightened you should be okay.

The question is, how did you tension the belt w/o the spring?

well someone came over to help me out. and what we did was with a crow bar i held the tensioner securely in place and he just tightened it where it was. Theres no whinning coming from the belt.

does the intermediate shaft have to be lined up anywhere?

does the intermediate shaft have to be lined up anywhere?

Nope, the only ones of concern are the crankshaft and the camshaft. Often times the intermediate shaft will move when reinstalling the timing belt, that is A-Okay.

Thanks. I fucked up and turned the crankshaft. Have it lined up now but now sure how accurate it is now? As long as the ot on the vibration dampener lines up with the mark on the cover then its ok?

Also the mark on the head for the camshaft is really thin right?

That's right on both accounts. So long as OT lines up with the mark, you should be fine. And the Cam marking is on the end of one of the teeth (tooths?) and lines up with the notch on the head.

added some pics for removing the cam sprocket seal and o ring


Cam sprocket /distributor rotor/plastic cover removed. the bolt has a star head
Also noticed the sprocket and distributor rotor are notched to fit onto the camshaft.


camshaft cover /seal/o ring.
undo the 2 bolts and you can start turned the cover loose.


seal replaced. I used a flat head screwdriver to pound the seal from the inside out. Then used the old seal to pound the new seal in.


new o ring


Once I slid the cover on halfway by hand, I used the bolts to slide the cover in all the way.


a pic through the front grill. you can see the mark for tdc on the head which you match to the mark on the cam sprocket gear. This is incase you move the camshaft when you tighten down the bolt.

Great writeup! Used this last month to do my timing belt (along with a bunch of other things).
