Engine has started leakin water into engine and doesnt seem to be oil pressure comin to turbo. Any1 experienced this b4 or know whats wrong?

 

[Mursal]

Low oil pressure because of the water, hopefully just engine oil cooler. See can you locate coolant pipes going to cooler and join together, just to test. Change engine oil .......

 

[daveydiesel1]

Have changed engine oil. When drained it the first 1-2 liters came out was clean water. Filled her with new oil and turned her on and stop light came on but engine oil pressure light didnt come on. So this mornin decided to check oil comin to turbo to see if theres pressure but no oil came out when i took pipe off. Also is engine oil cooler infront o rad?

 

[agrimax]

Am not overly familiar with the Forterra but am nearly sure the engine oil cooler has the oil filter screwed on to it....More likely the transmission oil cooler is in front of the radiator.
Does the engine oil pressure light come on before you start it? If the oil light does work ok,you'd be better cranking over with the stopper out (or wire of the fuel stop solenoid if applicable)and see if the light then goes out. Really needs a gauge screwed in to determine what pressure is actually there. Turbo will die very quickly if you start it with no oil feed..........I think the turbo gets it's oil feed from the filter housing above the cooler. So if there is a hole in the cooler,I'd have thought there would be oil in the water as well. So,would it follow that oil pressure would be lost to the coolant and therefore be prevented from reaching the turbo? @Mursal

 

[Mursal]

I would have thought oil pressure will be at turbo regardless of cooler condition. Not sure why it has lost all oils pressure, best not to run the engine without oil pressure. Take oil filter off and crank over on the starter (not running) until oil comes at the filter .......

 

[Mursal]

Is it clear water or coolant in the oil?

 

[daveydiesel1]

The oil pressure light never came on. Possibly doesnt work but the big stop loght came on. Wasnt wantin to start engine again incase of destroyin crankshafy. Any ideas how to do away with oilcooler and check for pressure then?

 

[daveydiesel1]

Is it clear water or coolant in the oil?

Its coolant. The oil was grey plus there was water at bottom of sump

 

[Mursal]

Best take filter off and crank until oil comes, don't let it start. If you have oil going to the oil filter, work from there. Can you have a look over / on top of the oil filter, have you a can type container with coolant pipes attached?

 

[daveydiesel1]

Yes there is coolant pipes goin into top of filter. Will that destroy crankshaft turnin the engine over if theres no oil bein put to end bearings

 

[Mursal]

If you Google 'Zetor Fronterra engine oil cooler images' you will see what the can type cooler looks like. If you have oil pressure in the filter and the water in the oil has a smell/colour of engine coolant, disconnect coolant pipes from cooler and join pipes together, just to test.

Mabe get wee look at it tomorrow if get minute and hopefully it will be problem and not need full rebuild

 

[Clockwatcher]

Coolant leak into the sump is usually via the o rings at the bottom of the cylinder liners, we have had a couple of forterras with this problem over the years

Best check the cheap and easy fixes first ........

I'd think that or a blown head gasket would be the leakage problem too and a pressure test with the sump off would determine failed o rings but why no oil pressure as well?

Have you ever seen them loose oil pressure b4?

 

[leone75]

The water in the oil blocks the oil filter it expands the paper in the element
Crank engine over with filter off when new oil.comes fit new filter and see if you get the pressure back

 

[daveydiesel1]

So does the oil enter the filter b4 the oil pump or after it leaves the pump?

 

[Mursal]

Oil enters the oil filter as it leaves the pump, there is a gauze filter before the pump, in the sump.

 

[daveydiesel1]

Ok al check that today. Wonder would the sump need to come of to check pump filter
