Valve clatter then skipping
I have a 1991 4runner with a 3.0 w/111,000 miles on the odo. The other night it ran fine on the drive home, the next morning I start it and I hear lifter rattle for about a second, then most of it clears up. One lifter gets louder and louder, then the truck starts skipping on the #1 cyl.I pulled the valve cover and everything is where it should be, shims, buckets, lobes etc., I rotate the engine by hand and watch the cam open and close the valves like it should. If this was a chevy V8, I would say I had a collapsed lifter, but that isn't possible with buckets. Any ideas?
