True Roller For 94 to 95 opti conversion?
 

I ordered an electric water pump and a cloyes true roller "jegs part # 02209-3145", I read that this was the timing chain to use with an electric water pump so you don't have to buy the expensive $350 timing chain to run the water pump.

I opened up the box upon receiving the chain and examined the rollers on the chain, and to my suprise the metal covering the bearings has a slit where it looks as if it was wrapped around the bearing. I thought the entire point behind a true roller was that these metal sleeves were one peice and not pressed together. Someone please enlighten me.

Why can't we use a gear drive with an LT1, is it too noisy for the knock sensors? If so doesn't someone make a quiet gear drive? Or does it have clearance issues with the timing cover?

I'm wondering why it costs $80 for the wire adapter from the 95 opti to the harness, is there any cheaper out there or should I just ask for my free vaseline and take it like a man. :)

If you are referring to the harness that goes from the OPTI to the PCM, my local dealer wanted $145 for it. I found it online from Caspers Electronics for around $40 shipped, which is a pretty good deal. Here's a link:

This is for the 95 to 97 OPTI's. I did have to trim down a piece of plastic on the plug that goes to teh PCM, as it was keyed a bit different than my harness, but it works just fine.

Im interested in the gear drive portion of his question. Love to have that on the vehicle, may be noisy, but they don't break or wear.

A gear drive would be a knock sensors worst nightmare.

Thanks for the info atlantagajoe, I once had a quiet gear drive on a 406 sb chevy in my old 73 camaro and it made very little if any noise at all, I believe it was a summit gear drive with the aluminum cover and all. This was about 9 years ago so I may not remember it too well. Anyone have any idea on the true roller question in my earlier post, I need to know so I can either order another or send it to the machine shop my motor is at.
