Ran m20 with no oil, now sounds terrible😳

BMWs are tough. Drive it till it ventilates. It may last a long while.
I've taken apart a few M10's that should have grenaded, and yet they were still running.

Budget for an engine as soon as you can, though. Especially if you think track days are in your future.

Okay guys, I have an update about the car. Refilled it with oil and drove it around the block a little and after about 30 miles it seems to run much better!! It has basically all of its power back and doesn't sounds like a diesel truck lol. Still is a little louder than normal at around 3.5k rpm, and some odd sounds that kinda sounds like grinding at about 1.5k rpm and then it stops the noise at 2k, but it doesn't always do that. Seems to be all good!;D

really................. WOW............

Ok 1st your compresion is likely fine thats the least of your worries . Your rod and main bearings are SHOT.....

You need to drain your oil out and look for metal fragments, I am willing to bet that it comes out looking very pearlessent with lots of fine bearing material in it. After you pull the filter cut it open and look and see how much of your bearings are in there. That diesel noise you hear is ROD KNOCK, she be junk and every foot you drive is pure borrowed time.....

With as hard as it is to source good running M20 power plants used now a days, I would park it sooner rather than latter, and start looking for a good running M20 variant, or start collecting rebuild parts. Bearings, rings, water pump, oil pump and pick up, master gasket kit, head bolts, timing set, for bare minimum starting point. Hope you didnt fubar your crank too badly by spinning a bearing and need a new one, or need a few new rods and pins........

It WILL blow up in the near future and leave you stranded somewhere. Hope you have towing on your insurance!

Sticky?

sounds like your engine is fine and its fixed itself

For how Long?

Lol, I'm gonna take it to my local beemer mechanic and see why they say. I mean when I checked the oil there was little in there so it's not like it was bone dry. The very end of the dipstick had a dot of oil. :roll:

The engine is gone. That's it. Need another engine. Lesson learned. Check oil before you ever drive any other car.

There's nothing I can do? I mean it drives, just not very powerful and takes a while to get into high rpms, and it's loud.

Lubrication is a coverup by the government in order to rake in money and keep the paki's busy while we invade Iraq. You will be fine, engines probably on its period. Just keep rooting her until you wind up with blood on your cock. Only then will you know the truth.

p.s your engine is seizing up.

You are in denial. Your engine is history. You might be able to drive the car around the block, but anything further than that will require a tow truck to bring it back home.

its fucked..

don't keep driving it or it will chuck a leg out of bed

It's cheap to swap a whole working lump.

Okay for sure. I was looking at rebuilt m20s and they'd run me over a grand just for the motor.
