Smoke in hydraulic tank and 2 psi oil pressure
I have a 420c with smoke coming out of the hydraulic tank. The hydraulics work fine and have 800 psi on piston lockup. I also have 1 to 2 psi on the new 0 to 30 psi oil pressure gauge. Thanks

Just a shot in the dark. But is your hydraulic oil getting hot and boiling some moisture out of the fluid. Does your fluid look milky.
Surely there is no smoke coming from the engine thru the pump. If thats the case your engine would be full of hydraulic oil.

I would start with draining the hydraulic fluid out of the tank and pull the cylinders and manually drain out the fluids for each cylinder by pulling the cylinder rod back and forth to try and get as much of the milky fluid out of the hydraulic system as possible.

Hi,
Piece of an old gasket fall in and block the passage to the gauge?
I am kind of reaching there. Sounds like you have a serious issue....
Anyone work on the insides of that engine latey? Might have the oil pump timing out of whack. Also, if no work lately, might be a clogged up inlet screen on the oil pump.
