Subject: Re: G9 gearbox
Hi Colin,
My LG6 engine was "rebuilt" by bozos (perhaps they retained the stripped threads in the name of originality!). I stripped the front of the engine down soon after getting the car, and of course the vibration damper had to come off to remove the timing cover. Needless to say, it had received no attention whatsoever, & was seized solid. It was pretty easy to dismantle, clean & lubricate...think I sprayed it with WD40...doubtless someone will tell me that was wrong.
Anyway...now I get a fair amount of vibration between 60 & 70mph, so freeing it off in my case perhaps was the wrong thing to do...ho hum.
Your friend's logic makes sense, especially if the oil used was a heavier grade, or it hasn't been apart & lubricated for years. Thinking about it, could you not use a stroboscopic timing light to check operation? A white mark on the damper rim (anywhere) should appear stationary at a steady rpm, but move whilst the engine is accelerated.
