A question on my '68 3020

I have not been in here for a while, the old tractor has been doing pretty good. Baled a lot of hay with it already.

Today I noticed that some oil is coming down the back of the block, and rolling down the side of the bell housing. It appears that it is coming from the head gasket at the rear. Does anyone know if this is a known issue with these tractors. It does not look like a lot but enough for me to see and notice.

Also it appears to have a little bit of oil coming out the blow by tube. I mean after a full 8 hours of running it, it will drip a little bit. Is this something that I should be real concerned about, could it be related to the leaking head gasket?

On that same note, that dang foam stuff behind the engine, I've tried to look it up on JD but cant find it, anyone have a part number? And the only way I see to replace the foam is to pull the operator station out, is that correct?

Thanks guys.
 
As to the foam, R56059, @ almost a hundred bucks!

It's in the PC under operator's station", CONTROL SUPPORT AND ASSOCIATED PARTS, Key # 15.

As for the foam I replace it when doing a clutch job(tractor split). I bought a bulk piece of cab interior and cut/glue in place. This is better as there aren't as many holes for the dirt to filter in under the dash. I just slit the foam so it forms around the linkages or lines.
 
There is a port at the back of the block that allows oil up into the head and to the rockers i would wait till in needed to pull the head the little oil coming out the pipe is not a lot to worry about
 
I agree with Kent. I would not tear it down for that small leak. The back right corner is where all 3020's and 4020's start to leak with enough time and hours. As for the foam I would not worry about it being gone. It was to help keep dirt out of the dash. They just rot up with time and hi pressure washers get hard on them as well. Or do like the other poster said and make yourself one. Deere has gotten very high with those kind of misc parts. I have six 3020's here now and have 4 that we use on the farm one has 9700 hours and has never been worked on (but needs it). Tom
 

Thanks for the info. I may just pull the head and replace it since we are done with the season and I have off this week. I finally got most of the hydraulic leaks fixed (need to rebuild steering still) and it bothers me to see oil running down the back &amp; side like that. I pulled the hood off, it don't really look like that big of a job except the exhaust manifold is pretty rusted so I think it would come off with the head in fear of breaking bolts off. That and the head looks heavy as all get out so I will have to use the gantry to get it off.
 

If I decide to wait to change the head gasket at what point is the oil leaking down too much. I ran it some more yesterday. After wiping the right rear side down and running for about 2 hours I can see the oil running down the side. It goes from the head down the bell housing area. The thing I noticed is that it takes a while for it to start leaking, it has to be good and hot.
 
OK so called my local JD dealer about head gaskets and bolts. He pulled up the gasket pretty easy but the bolts asked for a block # so I ran out and got it, my block # does not match anything they have listed. My block # is a R40850R with a 13E113.. serial. Which made me concerned over getting the right head gasket. So he is going to call a "guy" about it and see if he can make sure the head gasket and bolts are correct. Anybody have any input here?

In addition is there any other gaskets I should be getting at the same time for the job? I do not plan to pull the exhaust if I can help it.
 

Nevermind found a gasket set through SMA (tisco) and ordered it for half the price of just the head gasket through deere.
