Oh thanks! Something else to keep me awake at night. That's one of the problems with owning a vehicle without a local garage that's knowledgable with it. No one else here will touch it except Can Tire and I swore I'd never go there again. On the up side putting in a different motor fixed a lot of problems. I like many others had broken bolts and now it's quiet when I start it up. I was also having power issues around the 80 KMH mark and that's cleared up. And I always had a weird sound from the engine comp. that never changed. It sounded like a belt problem or something in that area as it was constant. The sound was there sice day 1 in '96 and never changed and two Nissan places wern't able to diagnose it. And since it wasn't causing harm the answer was to always leave it alone.
One other question for you...what RPM should I be at around the 100 kmh mark on a level road? I'm around 2800.
