alright this is what happened i just bought a 92 talon 5 speed, and replaced the head with a new cyclone head, well when i fired it up it seemed as the timing was off, so we set it right but now at normal idle something is vibrating, i htink i bent 2 exhaust valves or the bearings something happened but at normal idle it vibrates to where the timing belt looks like its about to bounce off, but at 2,5K rpm, it sounds smooth as can be it runs like a champ though just at low idle it vibrates and makes a vibrateing noise NOT A PINGING or KNOCKING just vibrating, does any one know what it could be and what i can do to check???

 

you might be a tooth off when you put the timing belt back on, who knows, just check it........

 

I don't think theres anything special about the "cyclone head" The MANIFOLD is the special part, but not the head itself.

 

yeah i know its just the air manifold is open larger then stock, i know, i think i figured it out though i think i might have a bad tentioner or whatever , but yeah i check the valves and nothing is vibrating but the tentioner is moving its not supposed to so im going to get a new one and put it on hopefully thats it... then ill be ready to switch everyhting off my black 93 on to this one...fingers crossed....thanks for the comments also appreciate it...

 

Did you line up the balance shaft correctly?

 

I would have to got with Ninety7GSX, did you check the balance shafts? It's pretty simple to get the rear balance shaft out of phase and it will cause the entire motor to wobble like a champ. My new motor will be missing the balance shafts

 

yeah everything was lined up i took it to a mech, and he checked everyhting out said everyhting is fine , but the tentioners are bad..there moving and causing the belt to vibrate everything.....well at least i hope thats it so i can get it on the streets.....thanks though.

 

The timing belt tensioner? (the pulley tensioner or the grenade pin style tensioner?)

 

i hate when my balance shafts are fucked up

 

it was the pulley tensioner, its moving around, causing the belt to vibrate got a new oneim picking it up tommorow and installing it..hopefully thats it so i can drive it...thanks...oh yeah how hard is it to remove the front passenger window, any tips??thanks...some dicks, broke into the car to try and steal the system but it didnt have one anyway...$%&!!!'s
