Well here it is. I finally got my hands on it. As far as I know it went from Jason to three people before I bought it. It's been beat and abused. It had a bad rod knock and I suspected a rod bearing being shot.

Some of the ghetto stuff going on from previous owners.

So I pulled the motor to tear it down and see the damage.

Everything looked good other than one of the rods had no rod bearings. At all. There wasn't even any sign of them in the oil pan. Not sure where they went...

Crank looks good considering there was no rod bearing.

Rod even looks good for how bad it knocked...

All tore down ready to go to the machine shop.

Wow, no rod bearing? This is the first I have heard of a lower end failure of a D24T. How did the rest of bearings look like?

Everything else looked good. Mains, rods, pistons, and cylinders all looked good. Sending the block out to be hot tanked and have everything checked. I wonder if there is a plugged oil passage which spun the bearing? Idk. Hoping to get away with just polishing the crank, new rings and bearings. Don't know if that's going to happen. :D

I would suspect a bad injector spring on the one cylinder that had no bearing, the bad or broken spring in the injector would cause it to be overly advanced in that one cylinder, thrashing that bearing. Or if IRC Jason had a heck of a time getting that engine primed with oil after being rebuilt, maybe that bearing was damaged long ago..

I would like to use a Cat fuel filter like Jason used but the threads are different size. Can you look and see what Jason used to get it to work?(pic's)

Thanks

Yeah I'll get some pictures for ya.

So I ran into my first problem. Prechambers are loose on two cylinders. Anyone have experience with this issue? Been doing some research on it, and I can't find much info on it. Thought about peening the head to take up some space or welding and machining it out?

Doesn't the headgasket/block hold them in? And there is a ridge to keep them from rotating?

I have heard about staking them in 5 places, as in a 5-pointed star, the top positioned at the precup hole so as to avoid interfering with the headgasket fire ring.

Did the headgasket leak oil out down the side of the block?

That's the downfall to these motors and high HP. My last head that I sent out to the rebuilder needed three of the chambers replaced as they where cracked (this head came from one of my built engines that was running a maxed 10mm pump and super 60 turbo with large FMIC pushing around 25lbs).

The builder I use for my heads has many years working on these heads, they always pull the chambers and re-set them in the head.

Depending how bad your head is you might be able to get a different chamber to fit snugly in the head.

The builder I use is Aluminum head rebuilders in Portland Oregon.

Head gasket was good as far as I could tell.

Having no rod bearings caused the piston to hit the head and it's pretty loose. The other one that's loose isn't bad.

Thanks for the lead on that shop. I'll give them a call. I guess I'd like to find a more permanent fix for the precups.

Finally getting this motor back together. I need a piston oil squirter. Any idea where to get one?

If you can't find one easily, I may have some spares.

Anders also has lots of engine parts and may be able to provide one if you contact him.

Good. GOD. What did they do to that poor car. Sad thing is, it was pretty fucking fresh when I sold it if I do say so myself. I bet one of the retards ran it low on oil or as was mentioned a failed injector. I cranked the battery dead twice trying to prime oil pressure as I remember until I jacked the ass of the car up as high as my floor jack could get it. Never fired it until it cranked 40lbs of pressure or so. I kinda doubt that was anything that started to deteriorate while I had it, I ran the shit out of it for a coupe years (and daily drove it for that matter). Big difference there was I actually took care of the thing, was very particular about maintenance, ran quality oil, and always let it warm up before running it hard. Sad to see how people ruin something you put so much effort into. Granted I sold it and got my price, but after all the work and research/trial/error to make it into what it was, I still find shit like this annoying
!

Anyway I'm back around with another '84 760 GLE cuz I just couldn't stay away from these damn things. As I like to say, junk loves company and i've got plenty of junk.
