As everyone knows the 3.8 is & remains littered with engine problems. Mine first blew @ 64k. Under the " lifetime drive train" they replaced the lower end. When it blew again @ 22k beyond they refused to do it again, sighting they did not like my record keeping...
It is the same problems that everyone else is having, bearings wearing way prematurely... Well we have, on my motor determined that " pinging " is why the bearings are wearing so quickly.
So in the analysis of why, we now believe the the source of the " pinging " is due to the contamination of the Mass Air Flow sensor, sending faulty signals to the computer. In return the computer is sending improper signals back to the injectors & creating " pinging " or the premature spark of the piston while it is still in the up stroke. This creates unique marks on the piston rod bearings. From the banging/premature firing of the cylinder. It also causes your piston rings to wear prematurely & may explain the oil consumption issues... Will advise on that.
What is the cause of the contamination of the Mass Air Flow Sensor?... Yep my aftermarket K&N cleanable air filter. Specifically, the oil mist from the filter contaminating the Mass Air Flow Sensor...
So it is going to be a full rebuild, crank machined to accommodate a lil better oiling, complete head rebuild, as surely the valves will also be effected by the " pinging " or poor fuel/air mixture. And the replacement of the Mass Air Flow Sensor & a Factory Paper Air Filter...
I think I am going to find out.. Sometimes the " Cool " thing, ain't such a Cool Thing!
