Just a heads up to any of you who are not aware to this problem,
if you own a 4d56 or 4m41 (2.5 & 3.2l) they have the commonrail diesel injection pipes pass through the rocker cover to the injectors from the fuel rail...
If you ever experience the engine
Lack of power (substantial)
Or u feel sumthing is a miss in general especially just after a 30,60,90,120 etc interval service
Have a good look at your engine oil level and take note of it, if it rises or oil smells like diesel fuel (raw) then under no surcumstances should you start it or drive it to even get looked at or fixed,
If the oil level rises and smells like raw diesel there is a leak at the injector pipe to injector and it's pumping raw diesel straight into the engine, two reasons why this is really bad to drive it
1. Can haudraulic the engine
2. The diesel fuel will escape out your breather in rocker cover and gets recirculated straight back into the intercooler, as diesels basically have constant air going through them and they are regulated by revs via the diesel pump you can experiance a (full throttle) sensation and in extreme circumstances turning the ingnition key off won't even stop the engine from powering on at full revs, (very bad if vehicle is moving) worse case senario if stationary would be conrods hangin out the block, the diesel injection pipes have a specific tension they are meant to be torqued to and if any of you do your own valve clearance services then I be more than happy to pass on any knowledge I know in this area just pm me
