My Alfa 156 1.8 TS is now sounding as a Diesel!?
After overheating the engine and the head gasket going I had the engine head checked and flattened, heaqd gasket and cambelt replaced, as well as the water pump and thermostat.
Now the engine is assembled again it sounds like what I would describe as a diesel engine. Although you donít really hear it when driving, when the engine is running stationary it is very clearly there. The engine seems to be running fine apart from the noise.
Does anyone have any idea what this could be? My car is being repaired by a guy who runs a one man's garage from his home and although I am sure he could replace a head gasket, he seems to be struggling to find out why the engine is making this noise. And he is suggesting that I have to pay for every attempt (and parts he buys) he makes to fix the problem.
Is it reasonable for him to expect me to pay him for every effort he is making to solve the problem and for the parts he has to buy. Even if this does not solve the problem?
First he told me he had to change some kind of a bearing (which did not help at all) and now he mentioned the tappets.... Do the tappets get damaged when an engine overheats, would all tappets be damaged or only a few and is it easy to see when a tappet is damaged or not? Any idea how many tappets there are in a 1.8 engine?
He told me the engine was flushed properly and he is using engine oil as advised by Alfa...
