Hi there.
I am in the process of doing a overhaul on my high-miler D24+T. It has been more and more annoyning to start in cold weather, due to lack of compression. But lately, another problem showed up. The engine coolant constantly turns black. I have done a coolant system flush, but it only lasts a few days, then the coolant is black again. So, now it is "engine-out-of-engine-bay-time"... ![]() ...Black coolant ![]() ![]() Also a bit leaky at the cylinderhead. ![]() Pulled the engine out at a friends house, and took the engine with me home. ![]() ...In the process of disassembling... ![]() ![]() Finally got the head pulled off the block. ![]() Good 'ol crackhead! ![]() ...Cylinder wall on the 6th cylinder not so pretty. Budget overhaul = Just deglaze it, and then done ![]() ![]() New vs. old pistonring. Guess which one is the new ![]() ![]() Block-cleanup before a new coat of paint. ![]() ![]() ![]() Piston-prep for new rings. Cleaning the grooves with a piece of old snapped pistonring. ![]() Pistons ready for new rings, and new con-rod bearings... ![]() When all the soot and dirt gets cleaned off, it reveals a thing that had happened in the engines youth. Notice valve-marks on the pistoncrowns. I think the engine have had a case of snapped-cambelt. I have driven this engine for a lot of KM's, so I decided the pistons are OK. Budget overhaul, remember ![]() More pictures will come, as the project proceeds... Happy newyear, ladies and gent's ![]() / Dennis from Denmark. |
