HELP GEAR KEEPS JUMPING A TOOTH!!!!!!!!!!

[Cory96EK]

ok so basiclly i got a PMR. I got it some what built an when we set the timeing an we turn the motor over with a wrench after about a turn an a half the intake side cam will jump a tooth on the timing belt. its the gsr timing belt and nothing in the motor is locking up because without the belt on everything spins freely. also if we rotate the motor in the opposite direction it does the same thing on the exhaust side cam...............PLEASE HELP!!!!!!!!!!!!!!!!!!

Make sure the timing is correct. Also set the tensioner after you've spun it over a little. Sounds like you have something that is binding. Don't spin the motor backward. What water pump are you using? If you have a 19 tooth water pump and a gsr timing belt that could be problematic.

[Cory96EK]

all the timing marks line up an the water pump is gsr the only thing that isnt gsr is the head. idk cuz when we take the belt of everythin turns freely.

IDK then. Is there anything in the engine or a bent valve.

[Cory96EK]

naw the motor has never been cranked because this issue came about an we didnt want to bend a valve. idk this shit is on my nerves

[Black4DrEK]

I dont know what happend to the other thread you made..

But I Asked if you "clayed" the motor.. To check your Piston to valve clearance and ect.....

If everything mentioned above is Correct..then..hmm.... ^^^ I would check this^^^

Stop turning the motor clockwise. Problem solved.

you SURE the tensioner isn't moving? I was sure mine wasn't til i looked after my belt came loose and it was in the completley loose position but the bolt had no less torque on it lol.

[Black4DrEK]

Nevermind I saw the other thread, It was in the All motor section..

Since you DIDNT clay the engine or anything and your SURE your tensioner is doing its job, I give up! GL

[Cory96EK]

if the springs r aftermarket an the cams r to is the valve lash stll the same

[Cory96EK]

im pretty sure that the tensioner is staying tight. we think we may be haveing clearance issues so where gonna try an re adjust the valves

[SPOOLIN]

make the clearance triple or quadruple what it should be and see if it will rotate fine....and then youll know.

[Cory96EK]

ight ima try that an see wut i get

[Cory96EK]

i found out wut it wuz the dumb ass mechanic never adjusted the valves when he got it back from the machine shop so they were so far down they were hittin the pistons

[Starrfire]

^^^Well I'd do something about your valves then, like get some new ones. Several members pretty much nailed it on PTV contact.

[Cory96EK]

FUCK ME!!!!!!!!!!!!!!!!!!!!!!!!!! OK SO I FIXED THAT (oh an the valves were fine they werent bent or anything) BUT I RAN IT FOR TWO DAYS AN THE FUCKER JUMPED A TOOTH AGAIN. I think its this damn ebay timing belt i got ima try a gates an see where that gets me. an also the plugs seem to be fialing out???? any suggestions???? cuz my car sounds like a subaru

[blackshine007]

Check your compression. Make sure to check the valve clearance while cold and make sure the measurements are exact for both intake and exhaust. If the compression is low and it's valve related, you might have burnt up a valve due to improper adjustment.
