Car Forum / Volkswagen / Water Cooled Volkswagen Cars / February 2007Whole lot a shaking going on
My 85 A2 Jetta Turbodiesel has just recently started a vibration at idle. Idle speed is about the same 8-900 and reving it somewhat does not smooth it out. Cold start can be on or off. Starts well. Seems to be running great, just seems to be shaking more than it has in the past. Any ideas? Slightly out of time?? Broken or wore out front motor mount or other , pump timing needs adjusted, low compression in 1 cylinder. fuel injectors are loose or leaking in the head . injector pump fuel line leak, or valves need adjusted. > My 85 A2 Jetta Turbodiesel has just recently started a vibration at > idle.

See if the vibration lessens. later, dave (One out of many daves) > Broken or wore out front motor mount or other , pump timing needs > adjusted, low compression in 1 cylinder. fuel injectors are loose or [quoted text clipped - 9 lines] >> >> Any ideas? Yea, a very good answer. Mine sagged once and it was rubbing metal to metal. >I vote the right side engine mount (cushion). <g> > Take a block of wood and use it on top of a floor jack to lift the engine [quoted text clipped - 18 lines] >>> >>> Any ideas? > My 85 A2 Jetta Turbodiesel has just recently started a vibration at > idle.

Carefully lift the engine with a floorjack and a block of wood with the engine idling to see if that stops the vibration. Also check the V-Belts to make sure that they are adjusted properly. Does the '85 Jetta TD have a throttle body and a carb? later, dave (One out of many daves) http://vwdoc1.tripod.com/ >> My 85 A2 Jetta Turbodiesel has just recently started a vibration at >> idle.
