i've got the astra mk4 2L turbo coupe (Z20LET) and some big probs.
1st when i started the car today i could here a loud tapping noise from the engine, i had a look but could not find where it was coming from,
i think this may be connected so i'll say the rest, last night i (by chance) looked at my engine after a long drive can the hole right side of the engine was covered in engine oil, earlyer that day it was fine, and theres no way it could be a leck cause it looks like it's been spraying the hole right side, top and bottom with engine oil, plus after that on the way back home whenever i went past 2000 revs the turbo kicked in and was hissing, a bit like it was supercharged, but it's not,
and now today it's tapping, and it's LOUD and gets louder when i rev it.
i think the engine is sha*ed but hope it's not,
i have it booked in for next wednesday but don't no if i should use it til then.
please i need help,
