It seems my timing chain is lightly grinding the timing chain tensioner. Didn't notice it doing this before the cam swap.
I replaced the timing chain and tensioner when I did the cam swap.
Do I need to go back in and change the gears too?
I am mostly worried about the tensioner material clogging the oil pickup screen.
Any ideas?

maybe order one of those double rollers and ditch the tensioner all together. If you think the gears are bad i have a spare set of gears i'll give you. I know there good shape and about 40k on them.
Yes im pretty dang sure you can ditch the tensioner with a double roller. However you will have to remove your balance shaft. Check the pics in this link at the bottom of the page.
It even says "Single Roller Timing Chain with new GM cam chain tensioner (left) vs. Double Roller Timing Chain (right):"
All the pics I find of the double roller do not have a tensioner installed. And i think the tensioner would not be wide enough to fit on both chains. The double rollers are alot tighter and do not stretch at all. All of the v8's Ive built i ditch the tensioner with a double roller. Im sure its no different in your case.
Regardless if you would like to try different gears, i do have a spare set that i know are to be good when they were pulled. Just let me know and you can have them, just pay shipping.
Ok on the same link i gave above, read this. I just found this:
"The double row set is designed ONLY for engines with the balance shaft removed (which requires plugging an oil feed hole on the rear side of the engine) or disabled (by removing the balance shaft gear). This set has a much tighter fit, so the timing chain tensioner is no longer used. We have found many engines that have had aggressive cams with high load valve springs installed, typically have their timing chain tensioners break after a short period of time, causing cam timing to become inaccurate, and debris to fall into the engine. By eliminating the tensioner, another weak link has been removed."

I think I might jump on those gears. How much do you think for shipping?
You don't have to completely remove the balance shaft to use the double roller, just remove the balance shaft gear, and somehow keep the balance shaft from moving.

I don't think taking th gear off would cause a problem with the shaft moving, if it rotates, it wouldn't matter and I don't think the gear controls the thrust on it.
It might be feasible. Anyone have an engine with no balance shaft? How bad is the shaking?

Ususally, when people remove the balace shaft, they have also upgraded the internals, and had them balanced well enough that the vibrations that would have been created from balance shaft removal are minute. My guess why the balance shaft was installed in the first place was to save on time balancing bottom end parts to exacts in the first place. You can find most everything from either Intense, which I believe stock all the parts you need to do the single roller chain replacement, including cam gears and such.

The balance shaft is there because the 90* v6 cannot be fully balanced by the crank no matter how well it is done. Its a fundamental design problem with the 90* v6, which is one of the worst naturally balanced motors ever.

I am pretty sure I will bite the bullet here and install a double roller.
The pic of that engine damage got me scared.
I will get it done sometime, and post results.
I will especially keep you posted Matt, and let you know if it helps.
I won't remove the balancer, just the sprocket.
I should be ok just leaving it otherwise alone right?
Hello every one, ozzy here ive been looking at this page for weeks now finally joined. So my question is why is it that every turbo build forum just ends...
Just ordered some Toyo 315/35/17 tires for my 17x11 rims. Hopefully I can get them on the beginning of next year. Will post pics.
