Not trying to be a smatrass, but Dion Warwick would have a better chance of diagnosing this over the net. The shop that did the work should at least look at it again for nothing. If it is doing the same thing, I'd place my money on the same issue. But I am just as likely to be wrong.

He is right! If you have the kind of stong personality go back and demand them to have a look again. but if they are real jerks that dont want to deal with MK2's then stay away, dont go back cause all you will do is frustrait yourself and they could screw up somthing els... :wink:
By the way sorry about spelling!

Could it be your exaust manifold cover thats loose?
Or I would get a clanking sound every time I would drive up a steep mountain in 3rd gear with very low rpms. I would have to shift to 2nd.
is that the noise you get?? :?

just to clarify on this....that garage fixed that problem like last year, so it would be useless goin back....and no it doesnt sound like that....it sounds like its coming from inside the engine....and like i said before, you can hear it from first gear shifting at any rpm(2500rpm for example)to cruising in second and you would just hear that pinging sound goin at it....also this sound also takes place when i start up the motor in the morning, when the oil is low.

If its "pinging" try going to a higher octane gas and run some fuel injector cleaner in it or you could retard the timing. The pinging is probably caused by carbon buildup, and one of those "fuel injector cleaner services" shops have should do the trick. The other problem you could have could be rod knock (replacement time), bad lash adjusters, etc. If its is either of these the noise should pickup as the revs increase. HTH

the car has always been running off of 93 octane gas....ok i put in more oil today and it stopped making the noise...but when the oil is low again it will make the same sound...and yes the noise rises as the revs increases...im starting to leak oil very bad, i mean very bad.

Same prob, I think

I think I got the same prob. It sounnds like only the 3rd cylinder. It goes away most of the time. But sometimes its real bad. But I am still not sure what it is. Its a little worrying.

I made the mistake of switching to synthetic oil, and started a real bad oil leak in my '86. I switched over to Castrol high mileage oil with a quart of Lucas oil stabilizer, and it virtually stopped all the leaks. Instead of a quart every time I fill the tank, it is 1/4 quart every three or four tanks.

If it is making noise, sticking a turbo on it is probably not a good idea. If you have to pull the pan anyway, check the rod bearings while you are in there.

i hate to be the bearer of bad news but youve got rod knock, it will never go away and if you turbo it it will blow your engine sooner. you either need to do a full rebuild or get a new motor. when the shop did the bearings, "if" they pulled the crank and had it turned then its not their fault as the oil leak has caused low oil conditions which will cause your bearings to burn up. if they didnt, then they need to rebuild it right. either way the bottom end is toast.

Help, I think

Ok, I have got a 1G-EU engine, so it is only a SOHC. So could the timing belt be the problem?
Can someone explain what rod-knock is? I am still a bit new at all engine bits.

I wouldn't be calling on rod knock yet, My suggestion to this, is when you hear this noise, like when you first start it, take a long metal object, like a screwdriver, coathanger, etc. and put your ear to one end and the other to a place on your engine to identify where the noise is coming from. If it's louder on a particular place in your valve cover it could be a bad valve or stuck lash adjuster, if it's loud in between the spark plugs, maybe a bad wrist pin, etc. If it's loud in your oil pan, most likely it's a bad bearing. If you identify it as the noise being in the oil pan or in between cylinders, start pulling plug wires while the engine is running. Pull them one by one and listen to see where the noise stops. If the noise doesn't stop it's most likely not a bearing or piston, if the noise does stop, you've located the problem cylinder. Hope this helps ;)
