"You need a new cylinder head" what were the symptoms the mechanic based that diagnosis on?

And did he just happen to have a spare one in the van?

Its why I try and do everything myself, you'll be pleased to know I didn't break the return pipe when I changed the forward glow plug on my 2030.

Well, in response to some of the questions, yes the engine has had all kinds of problems.
It starts up right away and it sounds pretty good. But that’s where it all ends. There’s some kind of white smoke or steam or vapor or something blowing out of the exhaust.
One day all the crankcase oil dropped out of the crank case. I’m not sure where it came from. It might’ve come from that filler thing from some kind of pressure. I really don’t know.
The mechanic says there is antifreeze in the crank case and other people have said that too. But the antifreeze is obviously going somewhere, because in the most recent episode every bit of the antifreeze disappeared, including that which was in the expansion tank.
So obviously something internally is wrong.
The head hasn’t actually been removed yet. The guy showed up too late in the day to finish. All I have on that score is the photographs that I have included thus far.
Here’s another photograph that I shrunk in size so it would fit on this site.
Thanks again.

Are you sure he didn't just say head gasket?

Think the best practical advice to the OP right now is to proceed, with caution (keep/photo/label all parts, don’t pay out or commit more than absolutely necessary, etc.), with getting the head off to diagnose the problem. Don’t buy any parts (gaskets or heads) until your(/a) mechanic has diagnosed the problem, which will need the head coming off. Any outlay on parts now could turn out to be a waste down the road - we’ve all been there. Cool your heels, get it apart, find the problem, then go from there. Plenty of help on here, as you’ve already seen

Yeah, I guess I jumped the gun. He said it could be the head but he hasn’t taken it off yet. And me, knowing that the problem is never a rubber band (it’s usually the whole slingshot!) I started looking for the part.
As noted, I’ll wait till he takes it apart and find out what the verdict is.
Thanks again for the advice. I wish I were able to do these sorts of things myself. As soon as I get a wrench in my head, however the tool immediately following will be a crowbar, a sledgehammer, or vice grips, none of which seems to improve the situation!

The head should be repairable unless badly corroded. Failing that you may be surprised when else that same head has been used so worth looking around. For example, I used to have a 1957 Humber Hawk, when I worked for Roots Groupe in the late 70's they were using the very same engine in new delivery vans called Fargo if I remember. Good luck

Well I’ve already located the head in New York State. I guess it’s an original Volvo one that the guy just happens to have. Of course I won’t order it until this week when my guy is supposed to look at the engine.
Thanks.

I strongly doubt you’ll actually need a new head. Wait and see and check if yours can be repaired.

Same as what I got the workshop to do when I rebuilt my 2040. Not very expensive either. IIRC.

Does infer from this that you are in the US? If so then pretty sure that you will find spares for the basic engine are much cheaper from a Perkinss or a Shibaura agent, or even a ford agricultural dealer as I believe the tractors are also sold under the Ford name in the US ihi-shibaura.com/english/aboutus/

Yes. I am in the US but the funny thing is that the Perkins people don’t seem to have the part in stock. If you go on the Perkins site you don’t see it. I believe the engine is called an M2. And I don’t see a head for that nor do I see a head for the tractor equivalent..

The head may be slightly different. There was an article in one of our mags a couple of years ago about the replacement of the head on a 2040 (4cylinder version of the same engine) which had failed when the injection pre combustion chamber broke free - not repairable. A Perkins head which had some slight but irrelevant differences - and a different colour! - was used. It was half the price of a green Volvo one. Heads so rarely need replacing as most damage, usually valves can be repaired so I guess very few are ever sold, even in the US where there are far more of these engines in use than in Europe. Perhaps you need to find a really good Shibaura or Perkins engineer or parts man who can identify the head and find the Perkins equivalent.
However this is jumping the gun a bit as you won't know what needs doing until the head comes off.

It is almost impossible to diagnose a fault over the net, but losing coolant could be a fault of the heat exchanger rubbers, or the clip coming lose, happend to me and luckily I tried all the clips and one was at fault before I started panicking

Would that put coolant in to the crank case, however? Because that’s where some of it at least it’s going.
