Engine 5.0 lifter tap until oil pressure gets up. Adjustment possible?

I'll drink to that!

At 66 years old with HIgh blood pressure the hangovers are killer now and last 3 days... Not much alcohol consumed here anymore.... Enjoy your youth...

Some of the replacement lifters aren’t much better.

I’d try the seafoam treatment, can’t hurt.

But honestly if it goes away when it gets some heat In it I’d let it be. Take it out and beat the out of it, might get better.

See above. SeaFoam added to the oil does wonders, just make sure you change the oil afterwards.

Marvel mystery oil, it's still a mystery, like who took the bone from the watermelon and put it in the fruit salad.

Theres a technique to setting the preload in a pedestal mount type valvetrain but it isnt easy.

You take the setup and torque bolts to specs. Give time for lifters to bleed if already ran.

Using the valvecover edge mark the pushrods using a very sharpened pencil. The thinner the line the better in this instance.

Take rocker arm bolts and loosen them and stop when pushrods are at zero lash and draw another line............

Remove pushrod and measure the distance..........If within specs of .030" +/- .010" youre golden.....

If not get longer pushrods and the right thickness of shims under the pedestals to put it them in range..............

Good Luck

That is good advice CAMTWO1070

The zero lash is easy to determine with the engine running and the valve covers off or a modified vale cover (one the top has been cut off)
You loosen the rocker 5/8 nut and it starts clacking like F76k. You then start tightening the nut slowly.
As soon as the clacking stops that is zero lash. Than you can add the 3/4 turn down or whatever

You guys do know I would hope that to try to turn your conventional hyd. lifters into the anti pump up type is to only add 1/4 turn down?
That leaves the plunger in the lifter bore near the top. Where, at high rpm and high oil pressure and when the lifter would normally start to float...
It cant float much because the plunger is closer to the top already.
So you would see old budget hotrodders only go 1/4 turn down from zero lash

Yes the pushrods are easy to rotate with the engine running even with a gloved hand (they rotate and stop then rotate and stop)
The cutout valve covers is the way to keep your engine compartment clean (at least it helps)
If you have a high volume oil pump or big oil pressure it's worse for shooting oil over the fenders and on to the car in the next stall
In that case some people modify a set of valve covers and just cut 8 holes with a holesaw over where the valve adjusting nuts are
