Audi ur-quattro 10V right engine mount replacement

Parts required:

• 443 191 381C Engine mount
• 443 199 443 6mm spacer - may be present and can be reused
• 857 199 386A Heatshield
• 857 199 765A Press fit bolt (x2) - optional
• M10 Nylock nut
• M8 Nylock nut (x2) - optional

Procedure:

• Remove right headlight
• Remove right undertray
• Remove inlet concertina hose
• Detach fuel feed and return lines (MB - silencers are NOT interchangeable)
• Detach single bolt holding cold start valve line on back of inlet manifold
• Undo air filter housing clips
• Pull connector off side of metering head (MB - also unplug fuel frequency valve)
• Swing/fold fuel injection over the back of the engine - injectors stay in place
• Remove air filter box - one remarkably long 13mm set screw
• Remove two 13mm nuts (care with spacers and grommet 'dishes') holding oil cooler bracket to chassis leg
• Pull oil cooler bracket off captive studs - lines stay attached - may be difficult if blocked by oil cooler lines
• Remove any remnants of old engine mount heatshield
• Top nut of engine mount should now be visible beneath turbo/downpipe
• Wire brush protruding thread using penetrant oil
• Remove top nut - how you get ANYTHING on it is your problem - may require extra ballast weight on engine
• Loosen lower 13mm Nylocks several turns
• Jack up the engine until the mount rattles
• Spin off the 13mm Nylocks, pull the engine mount down and off
• The captive studs are press fit bolts - they may be optionally driven out and replaced
• Remember that the new mount will need a 6mm spacer - you may need to jack the engine when fitting the new mount
• Do NOT forget the heatshield

This is a good opportunity to inspect the exhaust manifold with a mirror, checking for cracks and missing nuts or studs. Very little remedial work can be done with the head in place.
