Help with Massey

John St. · Jun 9, 2013

I have a Massey Ferguson 135 with a 3-152 diesel. My problem is it blows oil out the dip stick and breather tube when running.
The oil pressure gage reads high and stays there. Does not smoke out the tail pipe.
Replaced pressure relief spring in the oil pump.
Did not solve problem.
Can someone help me with this, Please...

This would indicate excess blowby caused by broken compression rings.Could be caused by using eather to start.traper

Don't worry too much about the high oil pressure, a weak gauge can send the wrong message!, better high than too low!
The blow-by is another issue, it is either worn bores or broken rings as trapper has suggested. The good news is with such good oil pressure you could get away with a set of sleeves, pistons and rings.

All the previous comments are true but there are some things you should check.. Valve adj.. Every engine manufacture says adj valves first 200 hrs every 2000 after.. Nobody ever does this.. Make sure the breather tube is clean. check that there are no restriction in the air intake. 0.10 on the valves hot if i remember correctly. .012 cold. never assume anything. wouldn"t hurt to check the timing.MF said "we didn"t get them marks right on all engines" so the made a tool to check this. good luck finding one.. finding someone with a diesel timing light would be easier..
