Do it and you will see a clear difference in build and engineering. Other things to look forinclude lifters that are moving loosely in their bores and weak valve springs. It is noted that the repairs are quite costly but it is also noted that it is cheaper to fix a problem than to wait for something else to break and bear the double expense. You can single out the faulty connecting rod by performing a cylinder-balance test. Both the rod and the crank journal it rides on []. The largest side load occurs during the power stroke, when there is a combination of inertia and gas loads that will push the piston sideways towards what is referred to as the major thrust side. even took the valve covers off, made sure all lifters were operating normally by visual looking at the valves to see if they were sticking while running. I have a 3800 series 2 supercharged engine and the tapping noise is coming from the front top of the engine so I checked the oil for any signs of metal on the dipstick and there werent any. Aside from this configuration, there is a reverse configuration in which the gudgeon pin is fixed to the connecting rod rather than the piston, which is implemented by using an interference installed with the small end eye instead of the gudgeon pin journals in the piston, which functions as a bearing.

The gudgeon pins are an interference fit in the rod. These side loads can have an extremely detrimental effect on the operation of the piston.

However, some manufacturers use the rarely known metals in order to produce the gudgeon pins whereas the others rely on the regular stainless steel which are forged in carefully controlled conditions. The double swivel action of the fully floating pin decreases the tendency under the heavy-duty conditions which are used to restrain the gudgeon-pin from sliding side by side. I had that once and changed out one of the injectors and the problem was solved. As for your comment that none of the faults where expected did you do any research into the vehicle and its common faults before you purchased it? Would that be main bearings?
