Hello! I have had a nearly flaless 3.3 v-6 in my 92 Voyager. Before I took a recent trip from NE Nevada to Portland, I thought I detected a noisy lifter. Days after I returned, the noise was louder (not deafening). I drove into town (14 miles) and one top mechanic said I had a loose wristpin. He ruled out a lifter. Before going home, I made another stop. Then as I was preparing to go home, the 'Check Engine' light came on and the van started running a bit rough. I decided before it died to drive SLOWLY back home on the Interstate.
I beached the car for two months and started it this afternoon. No 'Check Engine ' light, but after it warmed up, the tapping noise returned. I was advised to try and put it in gear (s) and see what happened. Out of P to reverse, back to P and the noise disappeared! Put into a forward drive or reverse, the noise is apparent. Nothing in P or N. Rev the engine and the noise returns at about 25K RPM. There is no loss in oil pressure; car does not overheat. I hate the thought of putting another engine in this van, as I did this last year. There is a slight vibration now, which I thought might be a bad spark plug wire. It appeared as the 'Check Engine' appeared. Today, in starting it, I ran it for a half hour and no 'Check Engine" light
I thought it might be the power steering pump, but have ruled it out. Another mechanic friend said it might be in the bellhousing, ie, loose converter bolts. Is there such noise that can come from the converter? I had previously towed a vehicle from Portland to NE Nevada. There is no change in the transmission. It shifts fine, fluid recently changed, along with filter.
Any and all help is Appreciated. I miss driving this beauty.
