ive had it timed 6 times,they cant do it by light,the pinging is gone..if i shut down in drive no dieseling.the balancer's rubber is pushed out and shakes.how do i know which balancer to get? or is it even the harmonic balancer.ive spent so much money having it timed and mixtures im at a loss.i bought the engine used with 50,000 miles and really know nothing about it.also wondering why at lower rpm in drive it doesnt diesel.im using 91 octane gas,

Have you tried different octane's yet? Maybe you could get away with running your tank down, then only putting a few bucks of a different octane instead of a whole tank and see if that's the issue. Also, I don't know why the harmonic balancer would cause dieseling, but I may just be missing something...I'm only a weekend warrior when it comes to cars. Personally, I kind of cheated here and there with my car, and would just call the Summit Racing Tech Line. I think everyone that answers is a car junky, and they know their stuff. It's a 1-800 number and it's on their website. It's like www.summitracing.com or something...that may even be it.

If the balancer is shot, you'll never time it right, and usually the mixtures are based on the timing. Start with a new balancer from a pro street shop. How about taking a look at the distributor where all the timing begins?

It sounds like someone may have taken the balancer apart. There is rubber between the two metal surfaces. If it has been taken apaprt it may not have been aligned properly. That would throw off your timing. You can get a balancer the the salvage yards. Also do you think your actane is too high? Thomas S.

you may have 2 problems about dieseling, first you may have carbon deposits on the pistons and valves. look up on the Internet for a BG SERVICE CENTER NEAR YOU and have them do a decarb on the fuel induction system. than have the idle speed adjusted properly, if the idle is set to high it will also cause diesling. take your harmonic balancer to a napa or carquest auto parts store and then can probably match it with other balancers.

If your car is manual shift, simply turn off the eng., hold the brake with your foot and let out the clutch.
If it's automatic, simply turn off the A/C, leave it in drive and shut it down. (don't forget to put it in "PARK" after)
This will eliminate the dieseling. Your only other option is to remove the heads and clean the carbon deposits, or lower the compression.

Dieseling after you turn off the car means your heads have too much carbonization. The deposits are like embers(glow plugs in diesel engines) that continue to burn, the valves remain slightly open due to carbon deposits allowing fuel to enter and burn causing the "dieseling effect". Keeping it in drive when you turn it off causes it to stall, shutting off the engine.

You should have never bought a performance engine with 50,000 miles. You know they have been hard miles. It may be completely ragged.
