 Black Soot in 1610D Coolant

Hi All,
Haven't visited the Yanmar groups for awhile. Things have changed. Anyway, here's my problem. I've got a Yanmar 1610D. Have had it for a few years and like it a lot but.....there are two symptoms that worry me a bit.

First, the coolant gets black afterawhile. Black as in soot, not as in rusty or just dark colored. The soot seems to be on top of the fluid, mostly. Not a lot, but a bit. I drain everything and clean it every year but it comes back.

Second, I have one piston (its a 3 cylinder) that seems to knock a bit more than the others at low revs. I put new injectors in last summer which didn't solve the problem and seemed to make it run a little worse in some respects.

I'm thinking I may have a headgasket leak. Maybe. But note I don't have bubbles coming into the coolant or at least I haven't seen any. Any ideas? I'd really appreciate any help you can give.

Eric

If, as it seems, it is a leaking HG you should replace it before running it more. There's a Snap On sniffer (and maybe other brands too) that diesel shops might have. It tests a sample of coolant for I think hydrodarbons from the engine.

The Yanmar motor that I was working on last month had the same thing, and it had not only a blown head gasket, but the head was cracked as well. Not such a good prognosis, but I agree that you should check it out before running it any more. Good luck. Oh, the gasket is probably close to a hundred bucks, well, if it was painted green, anyways.

Thanks a lot, Auerbach and Mobilius. I appreciate your thoughts and advice.

I gather it's pretty much a slam-dunk, if one can still use that term, that it's a headgasket--at least. I assume that would also account for the uneven running with a bit more ping or bang in one cylinder.

Not to worried about the headgasket but I don't like hearing about the cracked head. If it's that can they be welded?

Eric,

Like the others, I'm almost certain that you have a blown head gasket.

As for welding, I'm not so sure you'd even want to attempt it. If the weld fails.....and they usually do.......you'll have to tear down the engine twice, and install a second head gasket, besides.

The money you save by having it welded will, in most cases, never remain in your wallet.

But, let's not jump to conclusions here. Blown head gaskets are quite common. Cracked heads don't come along nearly as frequently.

Be sure to have the head checked out before installing the new head gasket. You'll want to make certain that it isn't cracked before installing any new parts.

Joel

Thanks for the confirmation regarding the blown head gasket notion, Joel. Will start there--tearing it apart and checking the head before putting it all back together again. I gather a machine shop can check out the head. Then if cracked I get to look for a replacement.......

Thanks again to you all. You been very helpful.

Eric

Eric; I don't remember what they call the gizmo, but most machine shops have a magnetic thing where they use iron filings to detrect cracks in heads, etc. I've had them do it a time or two. Frank.

Make sure you pull your injectors before taking the head to the shop. Put them in plastic ziplock bags to prevent contamination. They are very finnicky about dirt, etc.

Good luck!

Magnafluxing. I think they have new techniques that work on aluminum too, but definitely get the head checked out by a good machine shop.

Terrific. Thanks again everyone. That's all great advice. Magnafluxing without the injectors it is!

Eric
