The car listed above is a diesel, w210 e320 cdi. Just did overhaul a month ago. Tested atscan all 6 chamber pressure good and similar, no leaking of coolant and engine oil level okay. EGR and EGR valve good n cleaned, turbo good n cleaned.
Reason for overhaul, engine oil pump stuck and jammed after adding a stop leak. I wrongly add whilst engine not hot during changing engine oil.
After overhaul, starting good, but still using old glow plugs.
Whilst driving I hardly don't see blue smoke. On accelerating only see a puff of black smoke.
Any advice please. Tq

Additional information: during overhaul, 1 of the conrod found a bit sticky but was make good. Exhaust and inlet camshaft was polish and make good also.
