740 2.4 TD GLE - D24+T Budget overhaul

[volvo-dennis]

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
