Last week I replaced the intake gasket (and everything else along the way) to help curb the oil leaks. I drove it around Sunday and noted that it held gear a little longer than before due to TV cable adjustment compared to before. The shifts were good and crisp so I thought it was only better than before. I did hear a slight tapping once or twice after a hard run to 3rd gear, but the "noise" was too subtle and went away before I could attempt to investigate further.
Monday night it held 2nd gear until I let out and it may have overrevved. The tapping noise is not there when cold, but now constant warm and has the sound of a lifter problem. It is louder after warm up, and loudest at ~2000 rpm (or it seems that way). It will build noise and make the most noise when I lift the thottle at very light driving ~2000 rpm. To me it's bizarre that it gets louder when I lift.
engine unopened at 230k mile as far as I know.
no oil pressure gauge.
It's not a knock sound, but more of a tap.
I was going to pull the intake and start examining lifters, but wanted responses before my random search begins.
Thanks,
Scott
