i need some other than bad news - EuroBenz - 03-28-2011
After my brother used the car for about 200 miles, he brought it back with 2-3 quarts of oil left in the engine and a clanking noise. Every advice I heard was bad. I changed the oil and bottom oil pan gasket ( I was planning on it anyway) and still clacking that you hear more trough the exhaust pipe (straight 2") especialy when idling. What non-major things can I try before getting into more complicated things?

Straight-swapping in a new engine instead of trying to fix the fried one.

Couldn't just be something simple, like a valve adjustment. I found some turbo diesel engines for sale, they just have unknown condition. The car still drives as strong as before, its just the noise....

You can try using a long screwdriver against your ear to isolate the location the noise is comming from, or just buy a mechanic's stethescope. First thing would be a full oil & filter change, maybe a bit heavier of viscosity. Even if it is scrap, you might get some time out of it to source an engine if the car is worth it.
Or just flog the hell out of it....

Head is cheaper and easier.
More than likely bent valve. Welcome to my world.

What do you mean by head? And how cheap can it be in your opinion?
RE: i need some other than bad news - winmutt - 04-01-2011
I mean by swapping in a used head from the junkyard. Depend entirely on the price at the yard. Here it is about $50.

I say look for a turbo w123 on craigslist with a strong motor but tired body, and steal the drivetrain for your car.

Surprise, surprise! After driving around today, everything seemed to get back to normal. Shut it off then on again, everything good! Shut it off and drove to Tilted Kilt, and same problem. Engine seems to give up at every stop light. I'll have to hold on the brake and push the gas for a bit to keep it alive. I'll try a diesel purge. Could it be a dirty injector?

Valve adjustment?

It certainly could be.

I just saved a bunch of money on car insurance!
If it were an injecter issue, supposedly you can crack the line loose and have no change in rpm. I have tried this technique and not had any help trouble shooting. But It might work for you. I recently had an issue that sounds very similar. Just didn't seem to idle right at times, seemed a lil down on power. Went ahead and did a valve adjust and it was all down hill from there. Ended up doing a compression test finding cly. 2 and 4 at about 300 cold and 250 hot. 1,3 and 5 were 400. Pulled the head only to find the valve not seating.(On bench, turning cam by hand) seemed as if they would contact seat and pull in from the side. After disassembly found valve stems worn. Seats and guides ok. Condition: poor idle (low rpm,rough) tap/knock noise from top end, and had lick a thump sound from intake and exhaust.

i'd take the lower oil pan off
RE: i need some other than bad news - makin' smoke - 04-19-2011
Most possible is an injector. If a nozzle drips or gets stuck open, it will knock like crazy. The technique I suggested in the previous post should show that. The knock should go away when line of the injector is loosened. The knocking caused by compression is called "nailing".I had a bad injector that came and went as I was driving before. Maybe that is what happened when it cleaned up for a few starts.food for thought if you end up breaking the motor down; had someone tell me about a motor nailing that ended up being a bad oil ring. The oil drawn into the combustion chamber was acting as extra fuel just like a bad injector. Also a bad injector usually has blue or grey smoke. You should pin point the knock, top or lower side. If on top, use a steth or screwdriver/round bar/broomstick like yankneck suggested. you will be able to hear a difference. Let us know what you find.
