While the IM is off.....?

[Fat Audi 80]

Well chaps I have taken the plunge and pulled the IM and cam cover to paint them. Is there anything else i should do while the IM is off?

I have bought 4mm id silicone tubing to re new the vac lines.

Any BTDT's or preventative maintenance advice would be welcome.

Cheers

Steve

I'd replace the injector seats. Plastic ones are still available from Audi or I've seen a few people have made stainless ones.

Thanks Andy, i figured they would be made of chocolate by now and left them in place but masked the off.

Replace the oil pressure sensors on the side of the engine while access is good, also thermostat and coolant hoses while the going's good ��

Really best to replace them while you can. They are nearly always a point of boost leaks due to age/condition. Not expensive either.

This is a job I have planned for this year. I believe you need a long 13mm Allen key to remove the shrouds. I'll be interested in the part number too.

Consider vapor blasting for the parts. Should last longer than paint. Looks oem fresh from the cast.

Getting the old injector seats out will be a mare, mine broke into little pieces, lucky the head was off

Yes, and this was supposed to be a low budget, tins of paint only refurb...!

List so far is;

New Aux rad
New Cam pos sensor (Broke the plug during IM removal work)
New Lambda Sensor
Injector seats
Heat gun to cure paint
Silicone tubing
Various paints, primers, lacquers etc
New bonnet bump stops
Deox C rust remover (Brilliant)
Cam Cover Gaskets

Great list, thanks Ryan

Any time, it's worth giving it a good go over whilst there and then should be good for a few years to come with no issues
