And #2 main cap gone.
I found both pieces of the cap as well as both cap bolts in the engine bay. I haven't uploaded those pics yet. Coming soon.
That ALMOST looks like the #1 rod twisted off and sticking down between the counterweights? What's going on there?
i think it was the putter that poked the hole with cap parts..
410: No, I only found half of it in the pan along with the 2 bolts (which were undamaged!!). The other part of the cap is still missing
This happened a couple of years ago, and at that time I only took pics of the outside damage. I swapped the extra vented AEF (1.9 NA) for a 1Z and built a m-Tdi IP that I still run today.
Like I mentioned before, this engine still ran. All rods were completely intact. #2 rod did suffer some damage but I didn't notice until I removed it from the block. #1 piston also had a bit of its skirt broken off as well. All bearings aside from number 2 main cap were intact and believe it or not, the crank is in reusable shape. So, I guess I'm out one block, one rod and one piston.
Okay, here's some pics of the cap and bolts. After looking at everything a little closer, it does look like one of the bolts broke first, then the cap. The cap then breaks the remaining bolt at which point everything got ejected.
If you look closely at the break on the bolt on the left, the fracture shows signs of fatigue where the right side bolt was a clean break.
Mark, I would have to agree with you that this bolt was probably overtightened eventually leading to the failure of the bolt. Either that or the bolt was flawed but I doubt that.
This kind of damage is typical of a kickback when starting a motor on ether. I have seen this a number of times and ether has always been the culprit.
The bearing on number 2 cap was squished into a ball.
good god this is some most unfortunate carnage pics. Especially after just changing my main and rod bearings last week...
I think im gonna change my re-used (three times now) bolts for some 12.9 ...
