So there are liners?

Yes. I know some after market kits came with liners. There are a few people with liners in their motors

Man, I hate to hear that.
What were the conditions when it let go? In 4x4 low range?

It was highway driving, I still don’t know what happened, I took really good care of it after the rebuild, did oil changes in time, never over revved, used quality oil and never overheated, maybe the mechanic left something wrong inside of it, I’ll get it towed home on Saturday and I will tear the engine down on Sunday, this time I’ll be making all of the work, I hope it can still be fixed.

The number 4 rod bearing spun, I don’t have enough money for a rebuild, the crankshaft doesn’t look too bad so I’ll just polish it, polish the rod and the rod cap and throw new bearings at it, if I can get 20-30k out of the engine, I’ll be happy.

Hi,

I think you should first find out what is causing that condition.

Sure you can polish it and back together but you may be doing this again and again.

Also what about the other rod bearings? How are they looking?

Looks like you have a misalignment, oil starvation or lugging condition.

I would polish and check dimensions and clearances with a good caliper and a final check with one of those plastigauge to make sure you have the right clearance.

Here I'm attaching for your review a very good document in .pdf to help you identified what is causing your problem.

Thanks for posting the Mahle trouble shooter. Looks like a lot of help for failures like this one.

Always glad to help.

I meant a MICROMETER, not a caliper. Sorry for posting the wrong word.

Yes, use a MICROMETER when you done polishing to check dimensions and you will know for sure where you at.

And then I will do the plastiguage step after.

Thanks, it was of huge help when polishing the crankshaft and replacing the rod bearings, however there is damage to the rod and the crank, not in the journal but on the sides, it has a lot of side to side play, I put it together and risked it all, it fired up and the knock went away and I could drive it a couple of days to college, as it’s my daily driver; it could have worked for a couple of months but it has lost compression, before the rod spun it only needed the glow plugs for the first start of the day, now I need to cycle the gp for every single start, so I’ll just park it till have the time and money to tear the engine completely and rebuild it back again :(

How did it loose compression?

It was a new rebuild, right?

New sleeves and all, right? What kind of sleeves did you install?

Chrome ones? Cast iron?

What do you think happened? I mean what did make the engine loose compression so fast?

Do you have any idea? I'm just wondering because If the rebuild was done right your should have been running the engine for a long time.

Just curious...

Yeah it was a new rebuild, the loss of compression happened because of lack of lubrication... lack of lubrication after the rod bearing spun, the rings suffered even tho I didn’t run her long after the knock started.

If I remember correctly chrome sleeves were used, I expected the rebuild to last at least 300k, maybe the machine shop didn’t make a good job in machining the crank, and my mechanic at that time didn’t see it while putting everything together, whatever happened caused damages to my engine. This time I’ll be a lot more through with the rebuild.

Thanks for the info.

I think I know what may have been done wrong.

You said that chrome liners/sleeves were used.

Let me ask you this: What kind of piston rings did you use?

I ask because when you have chrome liners YOU NEED TO USE ONLY DUCTILE IRON PISTON RINGS or you will ruin it...

If ductile iron piston rings were not used then there you have it.

You may possibly have some other problems as well, like you said.

What piston were used? Chinese ones?

Or did you reuse the old ones?

Did you use one of those chinese rebuilt kits?
