Volvo DP-SM water in oil

[whitehills5093]

At the end of the season (yesterday), I went to change my oil in my outdrive. A volvo
DP-SM. When I drained the oil it was milky greyish. There was no evidence of metal chips. I change the seals in the 3 oil plugs every year and have never had a problem. Any ides for how to diagnose the issue?

And use soapy water around seals & look for bubbles…I have to do the water pump shaft seal on my Cobra this winter…it was last re-sealed in 2006…so I can’t complain too much!!!

Did you carefully inspect each of those seals for damage ? Might have installed a bad one ? I did one time. Magnifying glass showed a flat spot on the O ring. I do CHECK the daylights out of any suspicious parts.

Possibly a propeller shaft seal going bad. You need to pressure and vacuum test on the unit to see exactly where the leak is coming from.

So the vacuum/pressure tester is like $300. Then I would need the puller and tools to replace these seals. Not sure it's worth it or I should just take it to a mechanic.

Do it a little wrong ? lots more parts & labor.

I think it's worth having a pressure and vacuum tester, because some seals are not that hard to replace but there are some where you might need a mechanic, esp if the drive won't easily come apart for repairs.
