'98 V70 D5252T engine vibrations

I can take a look on vadis for you, see which one goes where. Will do that in the next day or two.

The car starts & runs fine, but strangely the mpg dropped dramatically after the belt swap??.

In my head I was hoping the belt change and re-time would sort it out...no luck!

I spoke with a friend of mine today (Volvo technician) and ran the symptoms of your car by him. I told him the belts were just replaced and that the vibrations were there before the change. First thing he asked me was if the dynamic pump timing was set using VIDA. He reckons the pump timing was out a few degrees prior to the change, the garage just marked up the pulleys and banged on the new belts, never bothered to correctly set the timing, hence the drop in MPG and the continued vibrations.

Have you considered having it re-timed?

Saw this car today, nice chap. IP timing is retarded by about -5.0 degrees, however this wouldn't nearly cause the kind of vibration he is experiencing, it is particularly bad.

Suspect is a shot front engine mount (the one directly below the crank pulley), there is a LOT of engine movement on that end.

Was advised by my Volvo repairer that the front lower engine mount on my car is beginning to split (1999 V70 D5 manual 131k). They are not sure whether a new replacement (this is the expensive one!) will solve the vibrations on tickover (idle). As previously posted my car runs very well in all other conditions.
My tacho shows 800rpm at idle and I know that the specifications say idle speed is 810-840rpm for this engine. I`m thinking that my idle/tickover speed is maybe a gnats too slow......If I gently increase the rpm by 20 it smooths out......going to see if the idle speed can be increased a touch.
