Dodge Journey 2014 Problems

Any time you have a dull, thudding or clunking noise inside an engine, it’s best to not drive it any farther and have that noise checked out. You may be right and the problem is an injector, but if it’s a serious mechanical problem inside the crankcase, you may find it suddenly lets go with catastrophic results.

Even if it doesn’t fail completely, you may be doing extra damage to the crankshaft, con-rods and bearings (and more) by continuing to drive the car. The problem could also be with the gudgeon pin(s) which secure the pistons to the con-rods. This is also something a mechanic would investigate.

The fact that the noise comes and goes with engine speed could be related to changes in the oil pressure masking the noise as engine revs rise. Bottom line? Have the car checked by a mechanic who should be able to pinpoint the noise. But be prepared for major expense if the engine has serous internal wear or damage.
