So, what fun and games this pile of sh#t OM651 engine is providing. The Injection pump appears to be leaking underneath from some sort of gasket, has anyone had this? Does anyone have knowledge they would like to share on removing the pump? I've whipped out the engine as it's impossible to...

I recall seeing that the twin turbo set-up used on the OM651/CDI220-250 engines, are wastegate type as opposed to (more common) VNT/vari-nozzle type. Anyone know if this is the same for all engines (because this was a document relating to OM651's fitted to Sprinters) and if they ever give any...

I know this is a previously discussed topic, but I thought I'd just add to it... Whilst in Germany on business trip the other week, I was chatting with a taxi driver about the OM651 engine (as you do!). This taxi firm runs a large fleet of W212's, with a mixture of CDI200 and CDI220 engines...
