Thread: valve set on a 318

Tweet

My high dollar 318 has a valve tick.

Been a while since I built a 318, how much turn on the rocker nut to adjust? I'm running roller rockers, does that make any difference?

over all you can get some valve train sound with roller rocker arms . back rocker off till you here noise draw the nut till just stops then a 1/2 or 3/4 max if that will not shut the valve train sound down you have other things goning on .for race stuff they will may make some noise we never went past 1/4 of a turn .you have the 318 magnum ?

Adding that a exhaust manifold leak can sound like a rocker adjustment.

No exhaust leaks.

Don't think its a magnum.

Thanks.

YEP that and noisy injectors rocker hitting valve covers

Nothing hitting. Does dodge have the same valve sequence as Chevy? Looks like there is no way to adjust these while it's running, I'll have to set them on the backside of the lobes

looks like rocker shafts are upside down-------- and with the adjuster nut/screw the way they look, you need longer pushrods

I want to sell this pos.

Why do you say that??????????just because you have a collection of minor very basic mistakes???????????

It's a big collection. And the biggest, most basic mistake, was buying this steaming turd.

Ok, finally got some feedback on my 318. I was told the valve sequence is the same for a sbc. Was also told the pushrods are symmetrical: can't be up side down. His opinion is that I probably bent a push rod.

Oh, he said ROCKER shafts look upside down. How do I check?

It's a sunny warm day in GA today (65) so I took a crack at it.

I put it TDC#1 compression stroke, and broke the rocker shafts loose, pulled the push rods.

Nearly all the rods on the right (pass side) were bent and all the rods on the left were straight. What would cause that?

How do I check correct rod length before I buy more?

The oil holes in the shaft are visible, they should be down against the rockers. That could cause enough friction to explain the bent pushrods.

Didn't I tel you the shafts were upside down in October?????

Yes, but I misread it and thought you said pushrods.

It's been on back burner since.
