S/n- 1jm362 oil in coolant a lot fast no visible coolant in oil. Changed oil cooler with reman cat. Tired floating oil out of rad got a ton of grey sludge but still keeps coming was just using clean water over filling coolant system letting it flow out rad cap. Have done this on 980s and 988s warm them up good in about hour all junk has floated did this one for three hours aND still looking for light at end of tunnel. So my question is what can fill coolant system with 2 gals of engine oil in 30 mins with out any in oil ? It has coolant through turbo but I pulled lines and ran for 2 mins with no sign of oil. Does water pump have pressureized oil feeding bearing ? Maybe oil cooler fixed the problem. Didn't test old cooler.... I got some cascade going to try that in am maybe that will do it . Any thoughts welcome my minds been off all day just couldn't quite mentally get into this one.
Only possible way of mixing engine oil in coolant is Oil cooler.
Cascade or a similar non-foaming detergent is the only thing that I have found will work if you get oil in the cooling system. Don't be shy about how much you dump in and you may need to repeat the dose, it just depends what the sludge looks like that comes out the first time. Run the engine at least 3-4 hours at operating temperature before draining the detergent/water mix. After this process it will need rinsing a few times with clear water before you add coolant.
Hey nige just posting some results on a few threads . This thing was a bear to get cleaned out. One flush I had 25 pounds of cascade but finally got it.
TBH I haven't found anything better for cleaning cooling systems even if it takes a few pounds of it to finally clean up a really contaminated system it will get there in the end.
