Help with Yanmar 2210 maybe a blown head gasket but would like opinions

[Chris Schurmann]

Hello Everyone,

I just bought a YM2210 , it was not running when I bought it. I now have it starting but it is missing and blowing a white puff of smoke when it misses seems to be ever other time it fires. I'm thinking a blown head gasket and have talked to Steve "Spalding Tractors" he has advised me to post and see what other input I can get from the users in the Forum.

Here is a video of the tractor on start and while it is missing and blowing smoke. it takes a a few minutes to see anything I was hooking up jumper cables so it only shows the tractor there for a minutes which makes it look like the video isn't working but it is if you wait till I get around to starting it. https://plus.google.com/+Christophe...6043790075094959234&oid=111135562855269414034

Please let me know your ideals to resolve this problem.

Thank
Chris

Try removing the radiator cap, crank and watch for bubbles in the radiator. If you hold your hand over the exhaust can you feel any moisture when the white smoke comes out? Can you smell coolant in the exhaust?

I like this gentleman's explanation on white smoke. Reading Exhaust Smoke, basic Diesel diagnosis/Troubleshooting + related comments - PeachParts Mercedes ShopForum

Any water in the fuel bowl?

No water in fuel bowl. I wish it was that easy.

Update, please give input.

Okay as of yesterday, we thought we had just a head gasket issue . But after pulling the head it looks to be a lot more going on. note the value and nosel imprint in the top of the piston, I guy I bought it from said he had the head reworked 4 years ago. I think it was planed to low on the rebuild and I know it was getting water.

Here is the video of the damage please give me your feed back on as to why i am seeing imprinting on the piston. I not they had over tighten a value and that's why I see it's imprint. video link below shows it all .

I can't pick up the video. Is the imprint on one or both of the pistons? If only on one I would not think it to be the head. Maybe loose rod bearing on marked piston? I think I would pull the pan and have a look.

It's on both pistons they left out all the nosel spacers when it was put back together years ago.

try this link and let me know if it works please . https://plus.google.com/+ChristopherSchurmann/posts/D78VMDuRZP3
