The original engine in my '89 expired do to spun bearings (all of them!), so I put in a little over a year ago, a '94. That engine had good bearings, no copper showing on any of them, so I put it in as is.
Last summer, I started getting some tapping under light load, which I attributed to bad lifter or lifters.
This morning, I started getting a much louder knocking, along with the squealing that the other engine did.
I have only run Mobil1 15-50 in this engine since I dropped it in.
I thought these were supposed to be strong on the bottom end. Is there any trick to making them live long-term?
5.0 is looking more tempting, or even another car.
I can't be swapping engines as an annual event-my wife would leave me!
BTW, it still has good pressure (modded stock guage).
