So last week on my way to school I was pulling off of the freeway and started hearing a loud clunk from my motor so I pulled right over. I had been battling some pesky oil leaks from my dipstick and oil supply line to the turbo for a bit now so assumed one of the leaks had grown and I lost enough oil to spin a bearing. I added some oil, started the car, noise was still there even at idle. I had the car towed home, turbo had lots of free shaft play and I chipped a fin on the compressor wheel. The car wasn't even low on oil, the oil supply banjo bolt was clogged, it ended up having a piece of rubber from a rubber coated washer I had tried to use to stop the leak on the supply line.. Dumb move.
So I ordered a 20g compressor wheel and a rebuild kit for the turbo, but decided to go ahead and drop the oil pan since my car is out of commision for the moment.. ILooked like a bunch of glitter in there OMG the number three cyinder rod had a good amount of play to it, the bearing was almost non existant.. None of the other bearings looked too bad, but had metal shavings starting to clog the oil passages. I cleaned all that i could with brake cleaner and qtips and replaced all the rod bearings.
I realize that this deserves a full out rebuild, but I have neither the time or the money right now to do that, so I need to get this car running as best as possible without pulling the motor. I have plans to get a 2.4L block when it gets warmer, but I need this car running at least til spring when I can ride my motorcycle everyday.
Tomorrow I plan to take some clean oil and run it through the motor in hopes of flushing out and remaining metal shavings. Is there anything else I can do in order to make sure I dont just blow this motor and turbo as soon as I am done putting it back together?? I'll also poke around the head tomorrow and see if I can find any shavings that made their way up, I guess I should go ahead and pull off the oil pump and filter housing too huh?

And also, when moving up and down the number 4 piston, it makes an almost hissing sound, as if air was rushing out a small hole. I had some oil above the spark plug, looks like a bad valve cover gasket.. Even after I cleaned the oit out and removed the plug, the noise remains whenever that cylinder moves. Is this normal? I never noticed it before.

Thats a lot of information to take in at once...kind of confusing.

First off, let me start by saying that if there is that much metal in the motor and the #3 rod bearing was almost "non-existent" then that motor is on its way out or already left...needs a rebuild.

How did the crank journals look when you replaced the bearings?
Did you check the main bearings?
Was the #3 the only bad bearing? If so, you need to find out what caused it, and fix it, or it will happen again...
Yes you need to disassemble the oil pump and the OFH. Clean the OFH, check the pump for damage and clean it.

If your going to run this motor without a rebuild, then I suggest you go here

K&J Magnetics - Products

and buy some high temp neodymium magnets for the outside of your oil filter and your drain plug. These will catch ferromagnetic material in your filter as it flows through. Alot better than a filter by itself.

Im not sure about the air leaking from piston 4, you need to clarify more...
 
Destroyed engine bearings tend to put more metal in the oil than the oil filter can handle, clogging it in a very short period of time and causing dirty oil to bypass the filter 100%.

Guess where this dirty oil goes next?

Everywhere :notgood:
Including your Turbo, which explains why his turbo took a crap.

To the OP, I think your trying to put a bandaid over a bullet wound...it's time for a rebuild.
 
You mentioned you replaced the rod bearings w/out removing the engine from the car? Im assuming you did not remove the crank and have it turned or replaced with another good one? If you just replaced the bearings then dont expect the engine to run for long. I would find a good running short block instead and swap it in, take the head to the machine shop for a good cleaning and put it all back together.

I second that :thumb:
 
bottom line motor is blown no way around it...nothing u can put in the engine is going to fix any of your problems...pull the motor and do a rebuild ...if u try to fix it the way it is u are more likely to ruin the whole engine as a whole block head riockers ect...
