vibration in motor/ Help
 

I have a 1987 turbo supra. love the car but it has a bad vibration coming from the motor it think. It starts around 1800 rpm. I dont know if its the clutch or harmonic balancer? I just had the motor rebuild. could it be something internal? I am stuck and would realy be thankfull for any help. Btw it dose it even if the car is not moving. Or if the clutch is in or out.

wierd.
my last engine blew up so i swapped it and the second day i got this new engine it has rodnock
well its not that bad but same here
when i hit 1500rpms or so it starts to clank but above that everything is fine.
i got someone to check it out for you though.
hit me up:gotnos:

I assume if the engine was rebuilt, then the engine was probably removed. Its not uncommon for the engine mounts to become damaged when removing the engine. Worthwhile checking the two side engine mounts and the rear one under the tranny are not loose or damaged.Are you running with the stock crankshaft pulley, the reason I ask is that if you change the pulley for one of those shinny bling ally ones there will be no counter balance on the end of the crankshaft.

Well glad its not what i thought it was.
One of those pulleys was my problem
the center one that keeps tension on the rest.
:cool:

There are all stock parts on it. I did have new pistions and arp head bolts with good head gasket also installed. But the rest is all stock.
