Tappet adjustment 3.3 turbo

[Greg930]

Easiest method, my book says both intake and exhaust .10 mm cold, but also says adjustment should be done with engine installed, and at TDC ..065 to.085, anyone know the best way with engine out of car, and which is the gap I should use, .10 or .065 to .085

Not sure where you read this, perhaps you can elaborate.

Valve clearance with the engine dead cold (ie no running for 12-24 hours) should be (.004) inches (or .10mm)

It's even easier out of the car, since access is easy. Set engine at TDC for cylinder 1. TDC mark on pulley should be lined up with case parting line and distributor rotor pointing to #1 wire/mark on distributor. Set intake and exhaust to .1mm/.004 in. Rotate engine 120 degrees so pulley mark once again lined up with case line, set #6. Continue through firing order.

I think the .065mm measurement would be if you're using the "backside" method of measuring between the rocker-arm face and the cam itself. I personally do not like this method, but here it is:

Thanks guys, Chris I think you are right about that being measured arm to cam, taken from factory repair man. How you doing Mike? Dist turns counter clockwise on the turbo, so which way do I rotate on pully 120

[Greg930]

Mike I can just take cap off and figure, rocket scientist not needed for that one, Ha

The pulley will move clockwise fro the engine to go forward.

Thanks Chris

if you try the back side method for at least one of the cylinders it will give you a better feel for how tight they should be when you measure the normal way. I had troubly with them being too loose and noisy until I tried the other way with it out of the car. the drag on the feeler gauge has to be tighter than you would expect. but now that i have the right feel no more noise and it runs much smoother
