Not really following your post on what the problem is, but I do not see how harmonic balancer would have anything to do with low oil pressure.

It could cause vibration in the engine sure, not sure how that would affect power either other than making driver want to not rev as high or maybe triggering a knock sensor?

Well harmonic balancer drives oil pump on our engines so if it comes out slighty it starts to loose oil pressure

As stated, the oil pump is driven by the clamping pressure between the pulley hub and the crank. A loose HB bolt has shown to be common on these cars. 1madstsv has his pinned, hopefully he chimes in.

Yea just wanting to know if any kit made for some other kind of vehicle will work on my car. Seen the ls kits comes with the guide piece for where to drill at and all bolts on to the pulley. so hoping something like that can work on mine

so had my slp crankshaft pin kit come in today for ls engine and i got to say whole process went very smoothly. would have been a pita if didn't have a lift but after taking air intake off and cooling fans out, got a right angle drill up in there and was a piece of cake. im not sure what kind of drill bit came in the pin kit but it drilled through the crank and balancer like butter lol. very satisfied with the outcome long as no more loosening up balancer, which it should be good to go now. highly would recomend the slp kit for 100.00 from jegs to anybody needing to pin theirs which sure isn't to many i seem to have bad luck with mine lol

Heck with it. For $100, it's an afternoon project to get me out of the house that'll add extra piece of mind as I mod further. Purchased.

HELP!!!!

My car is in getting work done, and they're attempting to pin the crank with the SLP part # 100250 "Crank Pin Kit for the LS motor" that I supplied them, per the above advice (see the web link http://www.jegs.com/i/SLP/847/100250/10002/-1 ). My shop is saying that it doesn't fit - essentially that the drill guide hole doesn't intersect the outer circumference of the crankshaft, and the inner circumference of the crankshaft pulley, to form a keyway!

Can anyone confirm that this is the correct Part #!??!?
