There are actually two kinds of engine fitted to the series 2 33. Early (1987) engines in the 33 and Sprint used the 1.7 with solid (shim adjust) tappets the same as the 1.5.
From later 1987 the hydraulic tappets were introduced. All injected engines use the hydraulic tappets.
It is easy to tell the engines apart. If the engine has hydraulic tappets it will not have any rocker covers, the cambox completely encloses the camshaft. If it has solid lifters it will have a rocker cover on each side (usually red painted) with four 10mm headed bolts holding it on.
If you are buying a solid lifter engine, remove the rocker covers and inspect the cam lobes as they can wear away at the tops.
Don't know about roumania or the UK but in Australia and NZ- (UK spec cars) there were quite a few of the early cars without hydraulic tappets.
I'm not happy to hear that my little engine hasn't hydraulic tappets and I must search all the pieces(like coins)and a good mechanic_it's so hard to find here.
Thanks for the answers,from now I'm sure.
If your engine has shim adjust tappets you could try your local VW/Audi specialist.
I have fitted a hydraulic tappet engine to my car but the cars with single lobe cams (105bhp 1.5 and early 1.7) have shims the same diameter as several VW/Audi models and fit straight in.
Setting the tappets isn't that hard, you just need a set of feeler gauges and a micrometer or vernier caliper.
Measure the clearance between the cam lobe and shim, write it down, remove the shim (you can do this with a couple of screwdrivers) measure it (it is often stamped on the shim anyway) and then subtract or add the thickness to get the correct clearance.
Sometimes you will find that you don't need to replace all the shims as you can often find that an incorrect shim on one valve is correct for another. Work out the shims you need first then you may be able to swap them around and reduce the number you need to buy. Good luck, I hope this helps.
