    Default Updated timing chain tensioner???

    Where's the best place to get one? My car has jumped timing twice in the last year, and I'm sure my old school 220k mile tensioner isn't helping any. I saw that Gspec has them for $100, are there any other options?

    Did you mess with the cams? How do you know the timing is off/what are the circumstances

    The first time it happened the car had been acting the same, but was melting plugs at the track all of a sudden. I went through everything and found nothing. When I checked the timing with a light, it was high. I manually turned the timing back to stock, and everthing was fine. Recently the car started hesitating when I would use the nitrous. I checked the timing, and it was low. Turned it back to stock manually and everything was fine.


    Funny thing is the first time when it was high, I had to turn the distributor almost all the way retarted to get it back to stock. Now this last time, I put it back toward the middle where it's supposed to be, to get it back to the same spot lol.

    I know this isn't a normal thing to happen. I assume it has to do with the sudden shock the chain goes through when the nitrous first hits. I really can't explain how it's gone BOTH ways now.

    I got mine from the local dealership because it was a sort of "instant need" - no time for mail order, unfortunately.

    I was also fortunate enough to have access to a dealership account, so, I didn't get robbed. Necessarily.

    Have you measured to see if the chain is stretched? Should be able to do it with a decent pair of calipers. Haven't heard about this in SR engines, but, KA engines? Seems to be prevalent... around here in 240s, at least...

    I wonder what it's like to actually "finish" a car. Currently looking for something near Schofield, or something I can ship here.

    Didn't know you were still alive man!!!! My chain itself isn't very old, so I doubt it's stretched.

    By any chance,are you running a stock crank pulley? If so might wanna check that to make sure the rubber is not gone.

    Yeah if you dont want to spend for a brand new one just get one used from someone off the forum. Fatboy's should be fine as its low mileage.

    I also have a couple but im not home to send you off one.

    One if have off the ve motor and the other I originally bought new from greg. They wernt 100 bucks back then though. About 70 shipped w/ gasket

    Ha, I just went back and looked again. The $100 one is for N1 motors, the regular one is $70.

    Yeah the only difference from the n1 to the normal ve/updated tensioner is the n1 has finer increments of locking teeth. Other than that, the strength of them as far as keeping tension is the same.

    Oohhhhh you're referring to ignition timing, not cam timing. I thought you were talking about cam timing because you mentioned the timing chain tensioner and that by "jump" I thought you meant it jumped on the crank or something. I don't think the timing chain tensioner could effect the ignition timing in that way.

    Hes talking about the cam timing jumped as in skipped a tooth if im not mistaken. The new tensioner will stop that from happening. Ive seen it happen only a few times and thats because they were original very very high mileage tensioners.
