What’s wrong with this picture?
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!:eek:
It is not going to look pretty inside that motor. |

Look way down that tube and you will find the missing part! :eek: |
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.
|
i can spot the problem - you haven't moved your new coffee table into the living room yet.

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

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.
|
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!
|
But....but.....but the IMS is rarely an issue per a lot of forum members on here :rolleyes: You have quite the mess there good luck with the repair .

I'd call that relatively rare. ;-) Sent from my SM-G930T using Tapatalk |
This is a 3.6 Carrera engine that I picked up cheap. My Porsche mechanic friend tells me that these engines are more susceptible to imsb failures than the 3.2s. I can’t verify the veracity of this but I’m looking forward to seeing what sort of collateral damage ensued!

Which IMSB update is on your broken 3.2? Can you transfer it to the 3.6?
|
it's not an LS1?
haha somebody had to say it Quote:

However: your proximity to raby's shop, (and your subsequent adherence to his religion), makes me unsurprised at your "testament" that IMSB related failures are imminent for all of us. Sent from my SM-G930T using Tapatalk |
I have the pro version. An expensive bearing. I can use it if it’s not damaged but I’d be surprised if it survived the mayhem when that rod let go.

Sorry about the rant but I don’t even want to talk about the $500+ (okay, only 400 US) that I just dropped for an engine rebuild 101 course from another of our favourite gurus which turned out to be a 4 hour feckin PowerPoint explaining to me basically everything that I already knew about these engines... :matchup: |
Well I could be all upset and rant and rave but what good would it do? I'm not happy but it was either fix it or sell it as a roller. What happened immediately before my IMSB failed probably had nothing to do with it. The other parts that failed were probably collateral damage too, but some kind of foreign debris must have gotten into the oil that was splashed into the IMSB and caused it to fail. Porsche should have used an oil-fed plain journal bearing here in its design of the IMSB IMHO. Since NeWArt now has an engine to rebuild with a similar issue, I wanted to share my painful experience.

And kk2002s, yes my true permanent solution is my daily driver, but not really as I just sold my Acura and got a BMW (with a BMW extended warranty though)! |

Sorry I don’t have it any more and have to leave it at that for now. I did see it though and it looked a lot like the picture of the broken one NewArt posted above except it was dual row. After being without my car for over 6 months now perhaps I’m more philosophical but I don’t think you can read anything into what happened in my situation and write off all the LN ceramic IMSBs. Maybe I should have had my oil changed more often or switched to the Joe Gibbs oil or installed spin on oil filter. My car was 15 years old with 68,000 miles and the oil was always changed at least once a year and always with way less than 15,000 miles between changes. At least LN gave us something better than the original Porsche design. And when I had the IMSB replaced the Permanet Solution was also on the market but I thought it was overkill at the time.

RE: RND replacement engines
NewArt,
Just saw a message posted 'today..' on Planet9 by Charles Navarro: SSF Auto Parts has 2.7 RND replacement engines on clearance as well with Nickies and IMSicon retrofit- that might be an option for less than a refresh on your existing one. |

Well that’s what I think, I’m not an engineer, but it’s my opinion. |

If you see my thread in the tech and performance section of this forum, you will see that I just missed out on the one and only 3.2 that RND had on clearance. Sad, it would have been a perfect solution. :( |
