Hi Guys. Reposting because my last post when clicked on goes to ebay ? ( Strange ).
The question is , is it a big job changing the Tappets on a Audi coupe 2.3, 5 cylinder ?
Thanks

Depends what you mean by 'big'.

I presume this is the 10 valve NG engine, rather than the 20v 7A.

You need to do everything that you would do to change the cambelt, plus remove the cam cover and camshaft.

Once the cambelt is off, the rest is quite easy - remove enough bits to get access to the cam, remove it, then change the Tappets. I did mine as part of a complete engine rebuild.

Soak the Tappets in clean engine oil for at least 24 hours before installation - otherwise they rattle like mad when the engine is first started. Also, if full of oil, they need some time to drain down after the camshaft is fitted. However, given that you have to fit the timing belt, water pump, front engine covers, crank pulleys etc. that isn't a problem.

If you do decide to do it, a couple of points:
1. The crank pulley bolt is horrendously tight. I had to acquire a 3/4 inch socket set and fabricate a locking clamp. Sticking the car in gear with the handbrake on wasn't even close to stopping the crank turning.
2. I can't remember if the head is alloy or not - if it's alloy, the camshaft clamp bolts have a nasty habit of failing and/or stripping the thread in the cylinder head - I certainly had this problem on the 7A.

Ian.
