Its very hard to read into people on the net, and sometimes hard to convey exactly what they are saying.. LOL.. Thats the bad part about the net and posting on forums..
Its rare for any 3800 to damage a wrist pin, its almost unheard of... Can it happen?... Sure its always possible, but uncommon... The L36 and L67 both use a floating wrist pin design... More than most I have seen 3800's spin rod bearings, this is usually after the oil has been contaminated with Coolant( Dex especially ), The bearings become pitted and its all downhill from that point...
Oil pump failures are also very uncommon on the 3800's... If a Pump is in good shape upon inspection I would reuse it in a rebuild... But with the inspection any scoring or scaring in the timing cover would cause me to replace the timing cover and pump..
I have my Old L36 sitting waiting for the day I build it.. Never had any oil pressure issues with it... Always had great oil pressure.. Didn't even have a wrist pin issue... I do think I was getting ready to pop the motor tho, Cylinder 4 has some massive piston to bore issues, Sounded a lot like bad piston slap when I pulled it..
In any event the real way to know what the oil pressure is would be the mechanical gauge..
Cman I agree... Fram oil filters = Skull with crossbones here
