The video was posted last week.. Subscribers got the link!
We were awaiting spring break to end before we shared it, as too many people we’re away on spring break. The share will go out tomorrow, in the mean time if you are a subscriber to Rennvision, you can see it now.
Only 17% of the people viewing the videos are subscribers.. We can’t do any more free videos unless that number triples.
That said, post a pic of what you found in the filter. Keep in mind- if it was found in the filter it already passed through the oil pump.
I have an idea of what this may be.. Did anyone pay attention to the length of the bellhoysing bolts when marrying the engine to the tranny?
Also, keep in mind the oil pick up tube had a screen ... Something that big won’t pass through the screen-
I subscribed but must have missed the notification.
Please say more about this teaser: “I have an idea of what this may be.. Did anyone pay attention to the length of the bellhoysing bolts when marrying the engine to the tranny?”
I always keep mine organized in a piece of cardboard, just because they are so different. What is the possible cause of damage if they are put in wrong?
Cheap shops and people that don’t know any better will run these bolts in with a power tool... Or wrench them in by hand when they start to tighten up too early.. It’s classic that shops doing quick and cheap IMS work do this... All they care about is time.
A long bolt in a short hole will break through the engine case in the bank 1 timing chain well. One piece of debris the size of a quarter will break out, and fall onto the bank 1 timing chain.. The chain will act as a conveyor belt to delive this to the Cam sprocket on Bank 1... The material is caught between the chain and sprocket and either breaks the chain, or retards the timing. This results in an instant failure.
So far we’ve seen this failure 23 times... all of which could have been avoided.

No metal in my oil and none on my magnetic drain plug. Swirled my magnet throughout the oil up and down and nothing. Drain plug barely had any paste on it...The big piece pictured is about 1/4" that came out of the filter and is very brittle almost like a piece of carbon deposit.
Thoughts?
Very (less than a finge nail) thin, it just crumbled when I pinched it flat between my fingers. No ridges that I could see. Almost looked like an old flake of rust (bulbous) but closer to a flake of carbon.
might just be a thing not related to your current problem. something fragile like that would not have made it through the oil pump i don't think. regardless, i'd be cautious of turning your engine until you are certain your timing hasn't pooped the bed.

I think you should go back to my original Prognosis, remove the plugs and see if a cylinder has filled with oil (AOS)..
It seems to me that something this size could only come from the oil filter cannister, the oil pump, pressure relief valve, or the oil pickup tube. These are the only things between the screen and the filter. Everything else would have to pass through the screen on the end of the pickup tube. This assumes the screen itself is intact...Hmmmmm
I really hope Jake is right about the seized alternator. Since the smoke was on the left side (crossed from bank2 cylinders) so the bank1 long transmission bolt theory should be less likely.

before trying to turn it also...
