UT400 First Oil Change Overfull Milk Chocolate What to Check

[Homeowner A]

Picked up an essentially new 2022 UT400 with 9 miles on it.  Decided to change the oil because it's probably never been done.  Pulled the dipstick and noticed it was overfull then went and pulled the drain plug and took off the filter and it was like brown water running out.  What should I start checking?

You have a blown head gasket

How and why?  

[Joe Breaux]

You have water in your oil...bad gasket  or cracked head allowing water to enter the cylinder..then runs down to oil. Mine did it twice. Had to replace head to stop it.

You might check the coolant level and its condition as well.

The coolant is at the right level and looks good.

No loss in coolant but high crank case lube levels?  Wonder where the extra crank case volume came from? 

Maybe try refilling with correct oil to correct level and run it a bit to see if the contamination reappears. 

Don't forget, if you have a wet clutch system, most UTVs do,  to buy engine oil compatible with wet clutch operation.

Good luck.

One other thought.  No telling what was put into the crank case or what may have leaked into it before you got it.

Any evidence this machine was in a flood or run in water above recommended depth?  Its a low mileage machine on its second owner. Did you buy from a private owner or a deaaler?

Can you see if the old oil will settle anything out of it?  Give it some days and see if it starts to separate.  You can help it by warming it up in a jar then letting it sit for a few days. 

These are more just guesses on my part.

I've done that and used Valvoline ATV/UTV 10W40.  Haven't had a chance to run it very much since, but everything is at the proper level.  I've run it with the coolant cap off everything seems normal coolant is proper color no bubbles or other funny stuff out of the ordinary.

This one hasn't really had an owner and it was part of a surplus auction when Tractor Supply closed out this model from their stores.  This is just one of several from that lot.  I purchased one of those units from the individual that bought the lot.  It does look like it was run in some water or mud, but no evidence that it was in a flood or in very deep conditions.  May have sat outside in rain some I don't know.  Not really faded or dusty or anything.  Nothing seems to settle out of the old oil.  The old oil was like dirty pond or creek water very runny pretty much like straight brown creek water.  Very overfull and to the point that steam was coming out of the exhaust.  It was all the way up near the upper portion of the dipstick.  Probably had double or more liquid in it than the ~2.5 qt recommendation. I didn't run it very much like that before I decided to change the oil.  Coolant is full looks good proper level and now the oil is too,

Maybe you got lucky.  I'd check it every start up and every shut down.   The OEM oil in my Hisun 550 (with Coleman stickers) was a tan color that alarmed me, but when changed it didn't separate and there wasn't any sheen present either.  I sort of wonder if they use whatever they have hanging around upon assembly and just ship it with garbage oil in it.  Who knows. 

Good luck hope it stays in good shape.  You'll know before long.
