OIL LEAK 08 SUZUKI DF140Z

[Birdman59]

I have a 08 Suzuki 140 HP it was over hauled in San Diego with a New Short block, Engine holder, Oil Pan etc,,,My Boat now is on Kauai Hawaii I notice Oil Film on top the Cavitation Plates and checked the oil dip stick and it showed half oil then I started the motor on the trailer and ran it 15-20 minutes turn off and checked the dip stick and now it only shows less than a 1/4" oil on stick! were is oil going? I wiped off the cavitation plates after I started it and since then no more oil film on the plates maybe coz its low already??? The work I had done was done by Suzuki mechanic at Shelter Island can't find him coz lose all my text in the stupid verizon cloud ! Now what should I check for? What else! I took off the complete Cowl Panel no leaks The Oil filter and cooler look new! I can't remember if he put a new cooler but it looks new! I just drained the oil and there was around 3.5 qts I took of the oil cooler it looks good but I'll have my friend connect it to a pressure hose to see if there's any leaks! It does look new though! Any other ideas and thoughts to resolve my Problem would be greatly appreciated since I live on a small island and there's not many Mechanics Thanks

Just a word to the wise (or unwise as the case may be). For heavens sake, don't leave the dock when the dipstick shows low oil level -- especially if know the engine is consuming or leaking oil which are the only two reasons engines do that. That is simply engine abuse for one thing and asking for trouble besides. An engine running on half it's oil is asking that oil to lubricate. Proper lubrication requires proper oil temperature. Yes -- there is an oil cooler on this engine. But think about it. If an oil cooler is required when all things are normal, is it adequate when only half the oil is present. That warning system works on oil PRESSURE as well as oil LEVEL. Those are two different characteristics. Understand them to save yourself some spendy repairs.

Silvertip - Copied your post from the other thread because it is good advice about running with the oil level low. It's in both places now.
