Hello,
This is a query with the wifes 2000 Phase 2 Volvo V70 T5 250hp.
Last week the wife took the car to the local garage to have to Timing belt replaced. While in we had the water pump replaced, tensioners & aux belt.
However, a few days later she mentioned to me a rattle noise when the engine is cold etc. I didnt think much of it, untill I heard it. It *sounds* metalic-like - almost like exhaust heatshield rattle or something.
However, the exhaust is fine and wasnt making this noise before the timing belt and associated bits where removed/replaced.
Now today, I had a proper look and when the engine is idleing the engine vibrates A LOT. As soon as the revs pick up above 1000rpm it smooths out. (This is stationary, not in gear)
The vibratons on idle are making the entire car shake, in particular the steering wheel etc and interior trim etc. (The car does have a Poly top mount) but then so does my 850 and I have dont see my engine in my 850 vibrate like this or interior vibrations as bad as this!!
My question is, if the when the timing belt was done the inlet or exhaust cam moved a tooth or so could this be making the idle very lumpy and the engine vibrate?
Like I say, as soon as the revs are above 1000rpm it smooths out.
I understand ME7 is 'clever' etc, but can a ME7 engine not adjust the timing on idle? But as soon as the revs pick up, can the ME7 alter the timing to compensate?
Any help appreciated, car is booked back in with the garage next week, just wanted some help as to whether we should be driving it?
