Hey all,
I own one of those ocean tractors. The V1501 - 56498 block with the Universal conversion 5432 on a boat.
I’m a novice but I’ve done a a fair amount of work on the engine myself over the years. I’m starting to tread water with this situation.
Appears there is oil in my coolant reservoir tank. Yet to see any coolant in oil. but loss of 30% on dipstick after 4 hours of running. No “milkshake”.
Ran a compression test. 380/390 across all. Tested cold and not WOT(my mistake).
My first cold leak down test (ever), believe I was at TDC, @80psi showed:
Cylinder 1 - air intake lite, exhaust lite, dipstick no, crank case slight,
Cylinder 2 - air intake good amount of loss, exhaust lite, dipstick lite, crank case lite
Cylinder 3 - air intake good amount of loss, exhaust lite, dipstick ever so slight, crank case lite
Cylinder 4 - air intake good amount of loss, exhaust lite, dipstick no?, crank case slight
Did not see any coolant bubbles from leak down test.
Thanks in advance for any help diagnosing this!
