About the only thing to do is remove the head and replace the gasket but have the head checked for warpage. I always at the dealer for years coated the head gaskets esp. on older and certain engines with a coat of #2 permatex on them. The older D6 & 9Us had a nasty habit of seeping along side the head and the permatex would eliminate it. I used the permatex on water connection pipes too.
Thanks SJ....I was afraid of that.....I do have some Permatex No 2 and also some Indian Head Gasket as well. I'll bet there isn't sealant on the head gasket now and that is the problem. The motor runs great otherwise.
I should have mentioned to make sure you change the seals on the ferrules between the head and block that seal water on most those older engines.On those ferrules and seals always put the more open end of the ferrule down in the block and the seals on them also look and you,ll see a little ridge of the rubber on the outside edge toward one end and put that ridge side (mold ridge) down in the block side too and then the head slips down over the more smooth part of the top side of it.
I have a NOS copper head gasket, listed to fit the D2 and R2, so I have to assume it's for a J series D2, which won't fit my later unit.
If someone has a use for it, I'd like to get my $50 back that I paid for it.

Alan...I have a later model D2 5U as well. I guess I will order from Caterpillar the gaskets. I know this will hurt a lot......
its not the compression release housing to head leaking?
My 4U is doing the same. I'll be changing mine before too long. Let us know if and where you find one. Thanks.
Well I found the gaskets....all I can say is WOW !!
The following is from an e-mail inquiry about the gaskets.
We do carry the top end gasket set for $412.50 and the bottom end gasket set for $742.50. These are engine gaskets sets-the seals in the bottom set are what brings that bottom gasket set up to a high cost. We also have the head gaskets for $195. These are a modern day heat resistant material with fire rings for $195 and the oil pan gasket is $42.50.
Plus shipping/handling-US orders-estimate only UPS Ground is $20-27
Can anyone tell me if this is about right or should I look further. A Cat dealer in Atlanta has not responded yet.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
