New Timing set options?

[TurboZ24]

The other thought is maybe these issues really arn't timing chain related, but maybe oiling related? I know Colin was having some oil control issues.

I have a large cooler too keep the oil temp under control, a high volume pump, and external oil pressure control (so minimum pressure is alwasy over 25-30 psi).

Are you saying that anyone who builds a 3.1 up, they'll need coolers and a high volume oil pump?

No!!! I ruined a perfectly good block and whole engine due to a high volume oil pump on my first motor.

Curtis can get away with the HV pump due to the extra oiling capacity he has from all the external cooler/pressure and line setup stuff. HV pumps require higher capacity oil systems. You'll starve the pump otherwise, I spun a cam bearing in the block (thus ruining a perfectly good block) from oil starvation.

I was only having low oil pressure during the end of the engines life due to so much shit (like the debris from what you see there of the chewed gears) from worn bearings.

The engine when it was brand new had great oil pressure and still ate timing sets.

I know about the HP oil pumps. My old 66 GTO had one and ate the main bearings. Only found out when we took the engine out to fix the rear main seal. I just figured the stock oil pump would be good enough.

It's kind of odd it seems. When the wagon's 3.1 was in Domenic's car, it ran a melling timing set without any issues at all. Just throwing out thoughts and Colin, didn't realize it was only a late in life issue with yours.

That pump is doing great in my turbo hybrid. Thanks Colin.

Not completely sure how many miles were on my old chain and gears. My speedo doesn't work since I swapped the transmission, so no odometer either. I'm guessing it was between 30,000 and 40,000km.

I pulled out the "good" (8mp) camera to get a few shots. Don't worry, I resized them down to 640x480...

Not quite as bad as I thought...

[torq455]

That dosen't look to bad at all.

[Superdave]

damn.. someone needs to talk to Pete Jackson about making gear drives to fit the 660.

Timing chains are soo....60's
after streaching one in my 355 i've been running a noisey Pete Jackson for the last 3 years with no problems at all

[torq455]

yeah.....noisy, i hate that!

[onefastV6]

That would be awsome if Pete Jackson made a kit for the 660.

Here is a quote from Summits website

"Better performance--accurate timing
Replace your timing chain with a Pete Jackson gear drive. Unlike timing chains, a gear drive doesn't stretch, so your cam timing stays more accurate. Pete Jackson builds its drives with dual idler gears, making them more stable than single idler gear drives. A Pete Jackson gear drive is as easy to install as a timing chain and will fit under your stock timing chain cover. If you want things nice and quiet, pick the "quiet" drive, or choose the noise drive that whines like a supercharger. Minor machining may be required. "

[Nightingale]

well I was planning on running a turbo or supercharger in the future anyhow so whats a little more gear whine gonna do heh..

[geoffinbc]

I saw a gear drive in the store yesterday that said "Machined For More Noise" I could totally see some poser installing that and claiming to have a supercharger.

I wonder just how quiet the quiet drive is....If I can't really tell, might be worth it.
