Any new news on this?

My nightmare has ended...drove home in my landcruiser last Saturday.
Still can't believe I have my fj40 back

It seemed to vibrate more then usual on the freeway, imagine the tires didn't appreciate sitting for nearly 2years.
Noticed an oil leak, valve cover gasket was replaced...will have to pull the skid-plate and investigate further.

Differences with this motor, over the old one?
Motor is from an 82 300D, so the turbo mounts lower then the previous (had to redo the exhaust).
Keeping the Original Mercedes Oil-Filter housing/system...no more spin-on remote-filter setup.
Max turbo boost is 8lbs...may bump to 10lbs as the previous.
the pyro is post turbo...where the old motor had the pyro at the rear cylinder.
Need to identify the new temperature ceiling.
I Also want to remove the EGR, have to see if the old parts work on the replacement motor.

Driving the fj40 around town yesterday, reminded me of how the sm465 manual transmission is sooooo not turbo friendly (especially with 35inch tires ).

I also noticed that the ALDA isn't hooked up, which was also the case in the previous motor.
I found that this wasn't very high altitude friendly, so I will prob. be hooking it back up.

I am also thinking of building a injector pop tester...maybe try rebuilding the injectors myself.

Regarding the old motor.
Other then a compression test (which recorded low), nothing else has been done.

I did pull the following parts before the shop sent to the scrap yard:
Intake/Exhaust/Turbo
Vacuum pump
Injector pump
Injector lines
Injectors

If I decide to add an inter-cooler, the later intake manifold seems to be a good way to go.

Did you determine what caused the old engine to fail?

I believe the cause was NO Oil Circulation, caused by the wrong oil filters that were installed by the quick oil change place.
My Universal remote oil-filter system did not have provisions for a bypass (common with universal), and prevented oil to circulate.

I know that excessive blow-by, lack of power and poor compression numbers was my new reality...all post indecent.
No other forensics was performed.

Just glad to have my 40 back...that's all that matters

glad to hear you made it back on the road. my 617 has been out of commission for 5 months now, still no re-swap.

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:

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:


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.

What a strange thread. I feel slightly pranked. Essentially no relevant information about the failure of the engine was ever provided.

97SL320 and others... thanks for trying to help the OP and other forum visitors.

Why destroy a perfectly good 123 or 126 after you pulled the engine?

maybe some one would want the body? what a waste.
