I drove the car home from work the other night (1 friggin mile) and before I made the driveway I started hearing a nasty rattle.
I thought the t/o bearing might be a little loose. I drove it back up there today and found the noise was coming from under the
left valve cover.
Pull the valve cover and find the #8 exhaust valve rocker loose. I adjust it, start it up and all is well. Drive 7 miles to my buddy's
shop and at mile 6.5 it starts rattling again. Pull the cover again thinking I did not tighten it properly, and readjust it. It is quiet
for a few minutes and starts at it again. :wtf
After several attempts to quiet it, it becomes obvious the the set screw in the poly nut is not seating inside the nut and is
sticking out above it.
So I either have a lifter that has dished out on the bottom or the cam lobe is going flat. Pushrod is straight, roller rocker is fine,
oil pressure is good, screw in stud tight, valve travels freely, not many options left.
Went cam shopping at Jegs. Got a Lunati 292/292 .512/.512 coming for it. That should make it nice and lumpy.
