Okay, for 15 points, can you spot the problem?

Is there a nut on that IMS center bolt? Wait... is there a bolt?

Edit: And it came from one of those silly cars that mounts the engine backwards (noticed tubing and harness).

Haha, clever boy!

Whatever it is, it also took the Oil Cooler!

It is not going to look pretty inside that motor.

NewArt · 01-18-2019, 04:46 PM

Look way down that tube and you will find the missing part!

Is that a dual row IMSB and it still failed? Maybe your cylinders won't be scuffed if that is what was making the knock.

No, it’s a single row.

Well FWIW my IMSB looked similar. The only collateral damage to the engine was a timing chain paddle on the back of the engine, part of the oil pump and the IMS itself. The crank, rods, cylinders heads, etc were all good and reusable. I hope you are in the same boat. And my block is finally in transit back to my shop from LN with 3.6 Nickies installed..

i can spot the problem - you haven't moved your new coffee table into the living room yet.

We’ll see. There’s always room for optimism.

Your engine fell out of your car.

BFeller · 01-19-2019, 04:59 AM

I m sorry to see that.

Thank you Paul for adding a sparkle into this dreary prospect!

FWIW mine was running too when the IMSB failed, at the valet parking of the Fairmont hotel at Mt. Tremblant before the first day of an HPDE. Shut it down and parked it, and restarted it one more time later that day so the 2 guys from my independent shop who were also at the HPDE could hear it. It sounded like a washing machine full of rocks running with no water in it. I also had very little metal in my filter or sump. My IMSB was an LN Single Row Pro with about 26,000 miles on it. I'm going with the permanent solution this time around.

Well, that’s some interesting information! Did you talk to LN about the failure? 25,000 warranty?

They're doing right by me. Stuff happens. Who can say for sure if the oil pump part, timing chain paddle or IMSB went first. I always stayed with Mobil One, didn't switch over to the Joe Gibbs oil after the IMSB upgrade, which was done at 42,000 miles. And all this happened after driving 10 hours from NJ to Mt. Tremblant in 100 degree Fahrenheit heat last July. I'll be happy to get my car back and do a few HPDEs this season,

If timing chain paddle or oil pump had gone first that should`ve left the IMSB intact. After paying over $800 hundred for a bearing that falls apart in 26000 miles I think i`d be a bit more disappointed to say the least..

So the engine was running, but was knocking... Were the ball bearings still in the race? What does the oil filter look like? You may have dodged a bullet.

NewArt · 01-19-2019, 06:06 PM

Yes, it’s odd that it ran. I only have the word of the guy who sold it. Not a lot of confidence. The bearing was completely destroyed. No race left. You can see the bolt at the wrong end of the tube. The oil filter had minimal debris in the pleats. I’m hoping to start the teardown tomorrow if I can get my garage above zero!
