Need a little rocker arm help
I bought the 360-2 heads for my 416 about 10 years ago. I might have 1500 miles on the motor now. The car has pretty much sat since 2007. I get it out a few times a year. Anyway I fired it up yesterday and the valve train was unusually noisy. Solid lift cam but something was off so I shut it down and pulled the valve covers. Oil everywhere which was good but I grabbed an intake rocker and it was real loose on lash. I just set the valves maybe 200 miles ago. Looked at push rods and could see they had a bunch of heat in them so I pulled the rocker shafts. Sure enough I had 3 rockers that mushroomed the push rod cup and beat up the adjust ball. Looks like lack of oil creating heat.
Shafts are fine, cleaned them up on the lathe with emery cloth but prior to that a couple rockers were starting to get tight.
I don't think I have an oiling issue here as far as the oil pump, pressure etc. I'm wondering if I'm letting the car sit too long between firing it up and I'm dry starting the motor. Or do I have a rocker arm issue?
A friend of mine who's and engine builder, mostly GM stuff looked at the rockers and asked me why there's no bearing (aluminum rocker to metal shaft) and also why the oiling holes in the rockers don't have a channel from the center of the rocker to the oiling hole? I told him that's the way they are unless there's something better out now that wasn't around when I bought the heads.
I also have one intake rocker that wasn't machined all the way on the oiling channel.
Bad rocker
All the rest where done right
exhaust rocker arms, no groove for oil.
Push rods
Where do I go from here? I've been out of the Mopar scene now for 8 years doing other projects.
I know I need new push rods and rocker adjusters.
Where can I get the rocker adjusters? I believe these rocker arms are Indy's. Do I need to modify them for better oiling or move on to a better rocker?
I need to get the car running by Friday. I'm committed to an event and the car needs to be there.
Any help here would be appreciated.
Thanks Brett
