How much bolt is still there? may have to add a washer to the bolt or shorter bolt. 1 or 2 threads is not good.

Jeep cherokee 2.8 CRD smoking. Replaced the injectors without any improvment. The garage told me that the smoke will stop after I have driven it for a couple of handred miles. Is this true.


from what you say, they said," it was the injectors that were faulty",hence changeing them,you could have tried a fuel additive/injector cleaner which could have had the same effect.....try a can to 5 gallons of fuel and if no improvement within 100 miles,give them HELL.smoke from a turbo engine could be dirty fuel/compression low/air leak from the turbo pipes/lazy turbo,etc but this engine is not exaclty the cleanest on emmisions.so expect a SMALL amount of smoke when cold or when accelerating HARD.

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!!
