Lookie what I found...

[Yamaha V6]

I purchased a 95 MTX with a known "blown engine". I have an oil dipstick that doesn't push in all the way, and I found chunks of metal in behind the throttle body butterfly. There was a half-inch of coolant in the intake plenum.

Here's what I think may be a chunk of piston ring in Cyl. 5 head runner:

Of course, there was also coolant in various other locations...

The rest of the engine pull & subsequent teardown will continue this week, with more pics if what I find is interesting.

Them is some thick coolant passages.

If you are going to yank the heads please get me some pics of the combustion side of the head. With all the other debris I would think the head would be pretty well chewed.

Any use for those pistons yet? I want to be able to say that one of Fred Hurder's cars is running my pistons.

Nope, sorry. I needed them at one point to build a block up, but found an alternate shortblock before they arrived. Right now, they're sitting in the box in a loft in the garage, along with a 3.2L oil pan, some covers, a couple of heads, etc.

As soon as I use them, I'll let you know so you can claim parentage.

Thanks for those pix! The engine I'm rebuilding was also "blown" according to 2 different mechanics. But I have seen nothing at all unusual, definitely not what you have in your engine. I've got it disassembled down to the short block, so I'll know soon if those guys were pretending to know my SHO. When I started pulling the motor apart I soon found one of the rear pug wires was not connected. They might have been too lazy to take the time to check the rear spark plugs!

Fred,

It's funny that you should use that phrase for the topic. That is the almost the same thing I said when I found the sight below after removing the intake manifold from a gentleman's car. "Looky what we've got here." I thought it may have been stuck under the manifold and fallen when I picked it up. But after a closer inspection of the fuel rail damper after its removal from the number two cylinder's secondary port, I realized that the valve stem had worn a deep groove through the rubber and a "sand dune" of oil-based crud was built up in the turbulent areas around it. That took a while. This engine was lucky that the damper wedged itself into the port rather than boucing up and down on the valve tulip.
