Hi, I'm doing a head gasket job on a K-series. Now, I've done this before on my own car, also a K-series, and the cross-contamination was such that oil leaked into the coolant, with the oil itself being as clean as a whistle. In this case I simply flushed out the coolant system until clean (although having said this the contamination was never that bad).
I have just lifted the dipstick on this other example, and judging by the huge build-up of sludge, I reckon the whole engine is FULL of oil/ water emulsion. What's the best way of cleaning all this out? My ideas so far are:
- Engine flush using proprietary engine-flush (Forte or similar)
- Taking off the sump and attempting to wipe out (?) the sludge, or use a degreaser like Gunk or something.
- Filling the engine with oil then draining, changing, repeat til oil is clean.
Any help gratefully received.
Thanks
