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.

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.

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

I mentioned this in a subsequent post.

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.

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.

I'm bumping this so it does not fall off the edge of the earth. This thread is a prime example of those with little knowledge of engines falsely accusing a shop of wrong doing

One has to agree this had nothing to do with the oil change. Circumstance where the piston finally just totally let go perhaps.

My original thought was far too thin of an oil may have caused more blowby than normal. This shuts down the engine basically or limits it to extremely low power with the excess blowby. Attempting to shut off the injection pump. Not that the thinner oil did any form of mechanical damage.

When buying a used engine for a 616, 617 or 603. A compression test is almost mandatory. The odometer readings are not to be trusted at all. So a pretty worn engine will still sound reasonable. Yet wear wise may be very long in the tooth.

I have never experienced more liars than when it comes to the car business. Most knowingly doing this unfortunately. So you have to do your homework.

I used to ride a Suzuki 2 cycle, 3 cylinder motorcycle, and it had a long tube with holes in it inside the muffler. I had no idea what the rational was to have that tube in the muffler. I do know I had to periodically clean the tube and make sure that the holes were clear. I was on my way home from work one day, and all of a sudden the bike started losing power. The bike would not go more than 40 mph. After I got home, I pulled the cylinders, and found a hole about the size of a quarter in the top of the middle number 2 cylinder piston. An examination of the exhaust tube mentioned above showed that most of the holes in the tube were clogged and must have caused back pressure in the exhaust which caused the hole in the piston. Replaced the piston, cleaned the tube, and everything was back to normal.
