Case 580CK Blow-by issues

[CrispyCritter]

Got an old 580CK which had a problem starting. Following repeated attempts to start it, and using a lot of ether, we found out the injector pump (Roosa DB2) had a problem. (a usual 'ring' problem we understand)
Got the pump rebuilt. When running the motor now, the dipstick & cap blows out part way, blowing oil out. A LOT of crankcase pressure.

Question 1).........
Is using a whole can of ether before the pump rebuild likely done bad damage? (holed piston, busted rings, scored bores, etc.)
I read a post which stated an operator's knee accidentally pressing the ether knob on a unit which messed up a cylinder.

Question 2)........
Is it a straight forward job to replace liners and pistons etc. on the 580CK? (I believe the front axle needs to be removed to drop the sump)

Question 3) .......
Any recommendations to what other parts to replace in a 'minimal' rebuild process? (not a major work machine - what are the basics?)

Thanks for any guidance here

Ether and diesel engines are bad. What has most likely happened is the one cylinder has had its rings cracked and the lands busted off. I do not advise replacing a single cylinder as it can cause balance issue. All cylinders should be replaced. Pulling sleeves in and out can be a pain. When replacing the pistons make sure you check skirt clearance and ring end gap.
You can probably do an in frame rebuild. I would also replace the oil pump. I would also have the injectors tested.

Thanks for your feedback. I guess we live and learn.
Any recommendations for parts supply (on-line?)

Why dont you do a compression test first? Also make sure your valve cover breather tube is clear of any oil caked dirt.

Have you primed the new pump and got alot of fuel out of the injectors?

Either can be used if used correctly. Dont hold the can wide open while cranking it.
