Hello. I have a grey market L1501DT. 809 hrs. Bought used just under 800 hrs.
Used a number of times for 1.5 + hr work sessions plowing snow, moving dirt, manure etc.
This spring - first time out ( not used over winter - ran fine in fall). Oil was noticed on tractor and ground. Stopped work. Upon inspection - oil was in radiator. With radiator removed, we pressure tested cooling system and it held 3-5 seconds before slowly leaking out.
Since then:
1) Got parts manual for L185
2) Replaced head gasket, water jacket gasket, oil filter
3) cleaned radiAtor, parts, gasket surfaces etc
4) head was air pressure tested at machine shop
5) Head and radiAtor carefully re installed, proper torque for bolts etc
On initial inspection we suspected the head gasket and the o ring was slightly compromised at the oil port/ stud.
First 15-20 min test run was fine. Next day worked 1+ hr to get engine hot and flush radiator. Oil light began flickering while in use after a while. Checked oil - oil was out of engine - into radiator again.
Note:Cooling system held pressure after engine stopped and still hot.
Next we plan to remove front cover and inspect frost plugs - I AM SEEKING ADVICE/SUGGESTIONS - what to look for, what to inspect etc. Thank you
