Water in Oil

[unclebraddah]

Bukh DV20.

Lip Seals on the Water Pump were bad and the relief hole clogged. I got a lot of water in the engine mixing with the oil.

I put on new seals and the after sucking, not draining the oil out it is still sluggish and hard to turn over.

I took apart the raised hand start and there was goopy glug in there. So I know I need to drain from the bottom. Ive run a few quarts of new oil through (The filters off and iIhave a new one) it. Today Im doing the oil pump.

Im thinking of filling the engine with diesel and letting it sit and then draining it. Good idea? Bad? What should I do to get all the remaining water/oil/sludge out?

DO NOT fill with diesel!!!!! You need to start engine to warm it up before you can drain **** out.

Got it

Thanks for that. Problem is I'm having a hard time getting it to turn over. Mahalo

I've no knowledge of your particular engine,but has it got decompreesors(valve lifters)?

If it has, and it's still hard to turn over,your problem is maybe a bit more serious than sludge.

I'd post this on PBO forum if I were you---you'll get loads of advice(some of it might even be helpful )

When I’ve worked on vehicle engines, if one had blown a cylinder head the oil emulsified with the water, one way of cleaning the oil system after repair was to drain the sump oil and refill with the same amount of diesel.

Run the engine at idle only so as not the damage the bearings for about 10 minutes, switch off drain sump again refill with correct amount of oil, turn engine over either by hand or starter but don’t start this will allow diesel still lying in pump to flow out at oil filter housing, clean up with rags.

Replace oil filter, top up oil, try starting.

Hot diesel removes a lot of sludge deposits from the engine casing, and gives a good clean out, works every time.

I strongly advise against this.

I agree in the case of a petrol engine but not a good idea for a diesel engine as the diesel in the sump could fuel the engine and it will run away and destroy itself.
If the engine is stiff and hard to turn, remove the injectors and fill each cylinder with a 50/50 mixture of engine oil and parafin and leave it for a week. Then turn the engine to remove the oil in the cylinders, change the oil in the sump and start it up. Let it get hot then change the sump oil again.

My engine manual states that to clean walls and the drive to fuel pump, drain 1/2 the oil,top with clean deisel, bring up to temperature ,stop drain sump refill with oil and hand crank a couple fof times and the engine is ready for service.
