    tapping noise!?!?!??!?!?!??!?!

    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,

    cheers

    are you sure its oil? maybe a longshot and im prob wrong but mine used to tap like that when i drove, found out the o/s cv boot joint had come loose, spraying grease up one side of the whole engine bay (making a mess of the alloys too).

    Don't run it, get it checked out ASAP, also check your oil level, a major leack should lower it.
    Tell me what you've done, not what you're going to!

    Engine oil tends to be inside the engine. If it's outside the engine then something is stuffed.

    Tapping in the engine after oil starvation could mean big trouble. Don't run the engine again, or you'll only do more damage. You might be OK just needing big end shells, run it much more and it's new engine time.

    sounds like a major oil seal failure around the turbo. hope for your sake that nothing is damaged!

    Ends, through oil starvation, could it have been maybe crank oil seal?, but yes turbo oil seal failure seems possible, either way it soesn't sound clever. Under warrently by any chance?

    2 out of 5 bars is 400ml. Astra dip sticks are 1 litre between empty mark and full mark.

    Oil has a habit of a tiny amount looking like gallons.

    Just to make you feel a tad more optamistic about the issue, I got to work one day in my old escort and there was OIL everywere..... My initial thought was buggered seal... Turned out to be a hole in my oil filter ( probably caused by a stone ).... I did not have any taping noise but probably would have if Id driven it any longer....

    Get it checked by a mech and DONT drive it anymore until it is fixed...
