I was in my friend's shop yesterday and saw this
First, I asked what was wrong with the motor and how many miles? BAD rod knock to the point that he told his mechanic to shut it off, because he didn't want a hole in the side of the block and have to explain how it happened to the customer. 60,000 miles on the mill.
Second, why drop the whole motor? He said his mechanic dropped the whole assembly out in 40 minutes! He's done hundreds of them and prefers it over trying to take the motor out the top, because it's much faster.
One curiosity to me is the twisted appearance of the balancer shaft
The water pump had been replaced about 1000 miles before the rod knock started. He speculated that someone used an abrasive wheel to remove the old gasket and some of the debris got into the front of the engine, which lead to a plugged oil orifice and galling in the rod bearing. He put this placard on the top of the motor while I was taking pictures.
The oil filter was still on the motor, so I asked if I could have it to cut open. The contents may help prove or disprove his theory about the gasket material.
This is what I found in the filter
All metal and virtually no gasket material. I've cut many oil filters and have never seen anything like this. This is orders of magnitude more metal than anything I've ever seen.
It is possible that the grit from the abrasive wheel doomed this engine. The oil had been changed about 3,000 miles ago.
We are going to take the pan off and get some pictures of the bearings. I'll post them when I get them.
