damper marks. crank thread probm

[Monterusto]

on my 89's crank damper there are 3 noches right middle and left none are colored.i understand the middle is white. which one is yellow or the first. and or whats what. i think i might hit them with a paint marker.

i also got a problem with my threads in my crankshaft. i pulled the crank pulley and grinded the first bit of threading. i couldnt get the bolt back in.(i tried bangin it in with the air gun. no luck) any suggestions.

Get a tap and run it down the threads.You may have seriously cross threded the bolt with the air gun.

does anybody know the thread bolt size for the crank damper?

Please do a search on the damper notch and bolt size issues. They were both recently discussed. A diagram of the notches was also posted and explained.

In clockwise rotation, the first mark should be yellow and when aligned to the "0" mark on the tab indicates the #1 cylinder is at top dead center (TDC). This mark is used for setting the tension on the 3.0L's timing belt. The second mark that passes the "0" index in the clockwise rotation direction is the white mark and indicates that the #1 cylinder is at TDC when at the "0" mark. This index is used to position the crank and cams when removing the old timing belt and installing the new one. The third mark that passes the "0" index is not colored and not used for the timing belt procedure on the SHO engine.

than. by the wAy i got a tap. the tap\bolt size was 308m-14x1.5

You may already have this fixed, however, here's the thread in which I recently related the solution to this problem.

when i was pulling the crank timing pulley its too bad that i didnt put a socket in the end of the puller in the begining (i did though cuz the puller got hung up on the fender. my autozone puller didnt come with a removable cap on the end of it(its kinda useful). anyway got my tap at a local hardware store for a whopping 28.99/17 snap-on. woulda saved ten bucks if i knew but im happier than a shtty pig cus i got it running again. for some reason it feels like it got a stronger top end(above 4500).i just replaced a cps and put the olt timing belt back on would that be normal? thumbs_u

How "old" is the old timing belt? That would have been a "free" opportunity to replace the $35 belt (Gates T248 from RockAuto.com) without any extra effort. Even proper re-tensioning an old stretched belt can regain some of the lost cam timing and horsepower, but only a new belt can recover all of it. Replacing the CPS should not have changed any power characteristics. The CPS either allows the engine to run when it is working or not when it fails.

im too sure of the age but it looked good for now.either way i forgot to install the cps clip, so when i get the money or in another 5000 mi or so i guess il take care of it. im about to run a timing gun and check for any codes which should tell me something about the belt(given the correct installation)?? by the way should i worry about that clip?any temp ideas if so?

My 13 year old 148,000 mile original timing belt still looked good. That doesn't mean it was. Looks are deceiving on those belts. Although it might have been far from failure, replacing my belt helped restore performance.
