Head Gasket Replacement - Steel Soldiers::Military Vehicles Supersite

Well, I found some oil in the coolant and have been running the Duce as a daily driver waiting for the next thing to break. I guess this is it, or the biggest on the list for that matter.

I ordered gaskets from Memphis Equipment.

Today I got her tore down. See the pictures....

The fourth picture is a drain on the rear-right side of the block to drain the coolant.

Its always handy to have some El Cheapo wrenches on hand to grind on and bend when you need to. I will have to buy a boxed foot to torque these bolts.
Anyone with a suggestion would be great.

Later,
Rut

BTW: Consumables required to get this far: One large Pizza and 6 pack of Bud Light. These were not supplied in the kit from Memphis Equip.

more likely cause of oil in coolant is oil cooler. have you found a positively bad spot in gasket?

I would take that oil cooler out if not already done. Mine was 1/2 full of a stuff I have not been able to identify yet, and really nasty. There are two o rings that seal it to the coolant supply and mine turned to dust when I removed it. If you got the engine set you should have every seal and gasket to do the engine. take your time and do it right!

Great pictures, Rut, thanks for sharing! Keep them coming!
Do these heads generally need a resurfacing prior to re-installation or is this unnecessary because of the split design (=less warping)?

When I rebuilt the top half of my Multi i had the heads shaved. one was .002 out and the other .004. I think .004 is the max for the multi but I had it done and it worked fine. I would think .002 is not much but with 22-1 ratio I would sure want to make sure all was square before I bolted it all back together.

don't forget to replace all the soft fuel lines while you are at it.

I will check the cooler also. I had oil and coolant leaks at the head gasket that were visible so it needed replacing. I only got the head gasket kit from Memphis not the entire engine set. bummer!

Went to town looking for heater hose couldn't find any. Goin to try Car Quest in the morning.

I am also trying to figure out how to torque a couple of these nuts when going back together. Guess I'm going to have to hit the Snap On/Matco guys.

Thanks for the Replies and Ideas!

There is a special wrench for those driver side lower cylinder heat nuts on the multi fuel. There is a discussion on this thread: All this for a freeze plug?!

and a link within that thread to another one where the wrenches are specifically discussed.

Thanks Clinto.. Good Thread. I had already read it a few weeks ago, but reading it now has much more meaning.

Funny, I have a set of Lycoming cylinder base wrenches in the box.. Cant remember if the larger wrench is 7/8" or not. If not, I have a welder and some sacrifice wrenches. Thank you Harbour Freight!

Looks like a good idea to hit the freeze plugs while I am at it. I hope I can find them locally and on Sat.

If I order an entire gasket set, does it come with new plugs? Looks like I will have to order anyhow because of the oil cooler.
