Engine oil problem... Updated

I've been 'doing up' a mates (air/oil cooled,) Yamaha Diversion XJ600. The bike was in a flood and as such the engine was filled with water.

The bike's engine was emptied, a new oil filter & oil change was done (by the owner,) however, the oil is all 'milky' again (caused by condensaition still in the engine I presume )

What do I need to do prior to changing the oil & filter again to get rid of the remaining water/condensation in the engine prior to doing another oil change Is there an engine flush product that would do the engine some good prior to changing the oil

HELP!

P.S. the bike is all done & ready for MOT, just needs the oil sorting out first

You can get flushing oil for cars, not sure if this is sutible for bikes though. There are also again, many engine flush products for cars etc.

Flushing oil tends to be thinner by it's very nature, what I'd do is get something like ZX1 (bonds to bare metal, about £20 or so) bung it in, then either flushing oil and run it to temp and refresh with good stuff, or a couple of changes (run to temp) of the cheapest oil I could get (car 20/50 will do fine, you know the reconstituted stuff).

I wouldn't bother changing the filter each time, but remove it and flush with petrol, only replace with a new one when you put in the good oil.

O, and let your mate know "wet bikes" are a different thing altogether

Cheers Mark.

Is that the friction reducing stuff

I'll give it a go - buy 5 litres of crap car oil & some good stuff...

Any more suggestions (except burn the bloody thing )

I always thought that water that gets into the oil eventually
evaporates if one runs the engine.

I heard exactly that too, just go on a nice long ride-out!

(That surely must be the best solution to a problem if it is true!)






(apart from maybe if shagging gets the water out of your oil hehehe)

I wouldn't go the flushing oil route personally.

If the bike has run OK, just do a couple of oil changes using some cheap stuff.

It doesn't take very much water to turn oil milky, and if you get water inside an engine it tends to "bead" on the oily surfaces so won't drain out freely.

Short of a complete strip (probably unnecessary if it didn't sit for long while full of water) just keep changing the oil till it's fairly clean. It'll cost a bit in oil, but that's the price of fishing a bike out of a pond.

My oil in the SV emulsified a few weeks ago when the cover blew off for all those rainy days.

Did a long run (450 miles) and it has all gone!!!

So it does work

When I dropped the oil out it wasn't too bad at all...

I've replenished it with new stuff (& a new filter - cheers Hein Gericke deal ) I put it in for its MOT yesterday & it passed (just needed a rear reflector 66p )

Chuffed to monkeys 12 months ago it was under 12 feet of water...

Ye gods Cloggsy, I know it rains alot in Yorkshire but pray tell how he got in 12ft of water Parking in Hull docks?????
