I would like everyone that has built / repaired broken engines to look at the top pic in post 43 and answer these questions:

Do you feel that lack of oil for a few minutes caused this damage in one cylinder? ( Look at the piston and rod bearing shell. )

If not lack of oil, what do you think caused this damage?

I would love to see that pile of scrap separated into ferrous and non ferrous. There are three round looking pieces and one with threads...

Foreign object damage. That rod bearing looks fine, as does the big end of the rod.

The OP started this Thread 2-29-12. then posts again on 3-03-12.

We don`t hear from him till 3-22,23-13, that`s a whole year.
Why don`t you answer some of the questions you were asked in that time?

Post some pictures of how your set up was before this Oil/Engine problem.
Show or list what filters you were using and show or list the filters the shop installed. Did you post another thread on building this vehicle? Post that thread. You must have some pictures of the build as you went.


Now we jump ahead another + year and you surface again.

Why start this thread of the problem looking for solutions, people jump in with answers, solutions and questions. You do not answer, why?

One thing I kind of get here is you do not do your own work of fabricating this engine swap, you farm it all out.

CHarlie,
The reason I haven't been online is due to work, and my fj40 was at my buddy's shop the entire time.

The Build thread is on another site:
mr manny benzo 40 - Pirate4x4.Com : 4x4 and Off-Road Forum

You are correct, I farmed out work for this motor conversion.
I've done, and continue to get my hands dirty...just didn't feel comfortable making custom motor mounts or spring perches.
Have you seen spring perches fail on the trail? Trust me, not a good situation to deal with.

I didn't post earlier, as there were no updates.
As me how much I enjoined paying 2 annual DMV registrations while it sat...NOT!!

I posted recently, only to provide an update.

Does not look remotely related to oil starvation.

That rod and piston are not stock OM617 parts either.

That kind of damage takes more than a couple miles of driving. I am leaning towards poor engine build and/or really worn parts. The type of thing that should have been easily detected with a functioning ear.

Perhaps really high EGT as well.

The pictures I posted earlier of internals were not of my original om617.

I guess the shop thought it was funny...definitely not appreciated

I mentioned this in a subsequent post.

What post? Your only post past 43 was this one that speaks nothing of wrong pics:

Hope to get more details next time I'm at the shop...

Currently no claim...expensive lesson.

In the end, even with just going by previous descriptions and no pictures, your engine did _NOT_ fail due to lack of oil pressure caused by a "too small " or " non bypass " oil filter.

For other readers: He took his diesel conversion to a quick lube place, they changed the oil, substituted a pair of regular oil filter for the Fram HP versions on the double filter remote he had installed. Lube place had him start / stop engine a few times to check / top off oil. He did observe oil pressure during all of this and it was OK.

A few blocks away on surface streets at low speed, the engine started to loose power / stall / have excessive blow by. The OP and a few others blamed the oil filter substituion as the cause of failure.

Even if the replacement filters are "too small" , 2 filters are going to have more surface area than a single stock filter. And. . .The engine was warm at the oil change place so lack of a bypass was not a cause either. ( Nor would a cold engine as the bypass is mostly there to prevent filter element crushing. ) Even if there was a loss of oil pressure, blow by will _NOT_ increase.

For some background, I've been in and around the auto repair business for nearly 40 years and have build countless engines , seen bent and broken parts. From your description, this was not the fault of the oil change place. Even if they dropped something in the intake, it would not increase blow by nor would the piston split in half in a few blocks. This engine was failing long before the oil was changed.
