oil pump sprocket in phase? engine viration

[DSM_ThuNDeR]

hey guys I have recently completed my 2nd rebuild.... Today everything check out fine... except when I took it out for its first spin, the car would start to shake alot... I'm pretty sure its because the oil pump sprocket isn't in phase(I DID NOT DO THE SCREWDRIVER TEST). The engine at idle with the timing set to standard(8 degrees) seems to idle JUST FINE.. the motor is really quiet, + the compression test landed me with pretty good numbers(185 accross). The car usually starts to shake above like 2000K rpms(somewhere around there). The safc2 also shows no signs of "KNOCK". I have readed something like this but on another dsm site... its a 95 gsx. just wanted to make sure before I start taking of the timing covers again. any input guys>?????

You have described the classic sign of balance shafts out of phase.
See http://www.dsmtuners.com/forums/new...aft-belt-merged-6-7-cutting-belts-remove.html for the reference thread on the subject.

By the way, if you rebuilt the engine and left the balance shafts in place I hope you replaced the balance shaft bearings. The balance shaft bearings are more heavily loaded than the main bearings and often fail before the mains taking the valve train out in the process.

yea.... deff they were out of phase... and I did the screwdriver trick just to be safe... It actually there is something wrong with the steering columb and the front right tire can be moved really easily from left to right while the car is in jack stands.. going to have to pay a visit to an alignment shop
