Question about 2003 Dodge Sprinter

1 Answer

My problem is with the 2.7 litre crd mercedes motor. it is fitted to my jeep grand cherokee 2003 model. Oil pressure drops suddenly but only when towing my 2 ton caravan/trailer. Pressure recovers but suspect it has been the cause of vehicle dropping into limp home mode. Any ideas?

I would only suspect that the oil is heating up,and a oil cooler may not be enough,a extra cooling fan,and a extra cooler for the oil might help,also thicker oil,if possible.Thicker oil only if the engine can handle it.Some of the newer engines have to have 5w 20,or 5w 30 weight motor oil.Thicker oil would only make it worse if this is the case.But I do suggest a synthetic motor oil,full synthetic.I hope this is helpful,if so,please let us know,thank you.

My jeep CRD 2.7 started to misfire at low revs in the mornings but seemed ok when warm. the injector on cylinder 1 then started to leak and it went into limp mode, this was repaired.A few weeks later it as...


Austrian assembled Cherokee's have a 5 cylinder 2.7 Mercedes motor. These are a serious piece of kit and put the US product to shame. Sadly they still suffer from the usual reliability issues . The worst of which is the habit of blowing the injector seals . As the engine is a tight fit and removing the rear two injectors require dropping the motor, this can be a very expensive problem and can happen as early as 40000kms. Still a great machine!!
