My knowledge of engines is very limited, so again, I seek some proper advice please! My 1.9 watercooled engine had a bad crank oil seal leak and required the exhaust helicoiling. So, she went into the garage, had the engine out, seals replaced etc. When I picked her up she had a distinct loss of power and ran like a bag of *rubbish*. I had a friend look at the engine and he did a compression test which showed low comprssion in 3 of the cylinders and very low in one. I took her back to the garage. He also did a compression test and told me the same. He advised that the engine was worn and I should look for a new one. My problem is that before I took her to the garage the engine was like a rocket, and I'm gutted. Would the timing affect compression? I think the mechanic messed with the tappets and as the adjusting screws are worn it is very difficult to get the timing back to what it was. Before I shell out for a new engine should I get a new set of adjusting screws (which are quite pricey for a set), or does low compression mean my engine is shot regardless? Please help
