I had quite a bad oil leak on my 2001 Astra Coupe Z20LET which I admit I left for too long. During that time the performance gradually got worse and worse.
Eventually it broke down and when the AA came out and removed the spark plug cover there was oil inside the spark plug sockets, espcially in the first socket.
He took the spark plugs out and cleaned the oil up, put it all back together again and it ran again. After a few miles it broke down again and I got a tow home.
The car went into the garage where they replaced the cam cover gasket and cleaned up the oil. At this point the car was working OK, but performance was poor.
So then the coil pack was replaced and after that it drove beautifully again for a couple of weeks, and then performance dropped off once more. I took it back to the garage and they replaced the breather hoses, which has not really made any difference.
It has never really got back to the performance levels that it should have and I'd like to get it sorted. A minor oil leak has developed again.
I have lost faith in the garage that have been working on it and I'd like to have a go at fixing it myself.
I know the spark plugs in there at the moment are cheapy and I'd like to replace the spark plugs, the cam cover and cam cover gasket in the hope of getting my car back to its former self.
So my questions:
1) I have no experience of doing this kind of thing, what are the chances I will break it completely? it does not seem that hard, but I don't really have a clue.
2) Do you think it will actually fix it?
3) Anyone know this engine really well that lives near Weybridge that would like to do it for me for a reasonable price?!
Sorry for the lengthy post, hope someone can help. If not im going to have to try and find a new car as this one just isn't right anymore
