rocker arm adjustment

[Veltboy618]

I had the engine running with the temp up & the valve cover off about to tighten one of my rocker arms because it was making a tapping sound hen I noticed I wasn't getting any oil through the push rods on the pass. side of my engine. I pulled the push rods out & none of the rods were clogged. I could see right through the hole in them.

Was the loose pushrod close to the back of the engine?

It was a couple loose. I dont remember which ones. While I had my engine out & on the stand I tried to adjust the valves. This is what i went by...

With the engine OFF and spark plugs removed so that you can rotate the engine with less effort.

1. Get #1 piston to compression TDC, Cam gear at 12 o'clock crank gear at 12 o'clock.

2. Adjust the intake valves on cylinders 1, 2, 5, & 7 by loosening the rocker nut until play is in the pushrod then just take the up and down play in the pushrod and tighten the rocker nut 90 degrees

3. Adjust the exhaust valves on 1, 3, 4, & 8 in the same manner.

4. Rotate crank 360 degrees to get cylinder #6 to compression TDC, Cam gear at 6 o'clock and crank gear at 12 o'clock.

5. Adjust the intake valves on 3, 4, 6, & 8 in mentioned manner

6. Adjust the exhaust valves on 2, 5, 6, & 7

Getting the '0' lash is the same as I posted originally. Use the "up and down" rather than "spinning" the pushrod.

Obviously this didn't work & a couple of the rocker arms were too loose. I tightened them down a lil to quiet the sound a little but its not totally quiet I guess because there is no oil.

If several of the pushrods were clicking,and thereby allowing the oil psi to slip out of the gap formed when the pushrod became loose,that MAY explain the lack of oil on top. I would start by re adjusting the rockers, then double checking them while running, get all the noise out of them, then check oil flow.

If you had the car running with the valve cover off you should have had oil all over your wheel well. In all of the engines I've ever built it's not just a dribble of oil but literally large squirts that get everywhere.
