Engine code and year might help.
Injector[s] failed?
What's the fuel pressure cranking?

You'd often get that P0251 code.
Do a leak-off test - I'm not a betting man, but I'd be surprised if at least two aren't gone.
The oil dilution would fit with injector failure too. [Don't fit re-cons BTW.]

I'm getting pretty jaded about common-rail re-cons in general. I'm recommending outright new only from now on.
Re-con Delphi ones never seemed to work successfully [but you couldn't convince a taxi driver...] and I've now seen two nightmare [non-Piezo] HDi ones in the last month - one on a 2.2 Relay and one on a 2.8 Iveco.
Both had excess[!!] leak-off and non-start; but the re-con replacements rattled and smoked their heads off - even though the supplier swore blind that there was nothing wrong with them on test. [New dealer ones cured both.]

| | ok so we think it is over fueling possibly an injector then running down the bores filling the sump up? i have a launch and see you can code the injectors with this but not had to do it yet? how easy or hard is it? how would you do the leak off check you mentioned? i get what your saying about using gen parts had alot of problems too. cheers for the help |

| leak of test is where you remove the leak back pipe and replace it with one attached to a messuring tube and messuse the amount of fuel leakin back on cramk for each injector
you can get cheap kits now
