V8 lifters....

[GURU]

G'day all, anyone heard of, or known it been done before. Taking the hydrulic lifters out of the 3.5's and fiiting solid state ones??

Think this would over come my problem of running on angles... But I run a P76 which the oil feeds from the lifters up the pushrods to the head from memory.....hmmmm.

Any other idea's ????

Yeh I have some ideas but i wont mention them Kids might read them.

will you be changing the cam to a solid spec cam? If so won't the style that you get with a solid lifter cam be a touch aggressive?
lots of the hillclimb bloke used to run p motors maybe try something along those lines If you know any one that doze that.

Yeah, I’ve used solids on 3.5’s ………….. but only on race engines where the std hydro’s run out of steam at 6K rpm. They should work OK on most cams but depending on the manufacturer of the solids you will probably need to shim the rocker posts to get the correct clearances …….. Solids make the engine sound like a bag of nails at low rpm, but at 7K any V8 is gonna sound sweet

If you’vbe got oiling problems at weird angles then maybe using a baffled or even a dry sump might be a better answer

yeah dry sump is my prefered answer...but $$$ is the killer...

Sump has good baffes in it already, I haven't tried this motor in anything but a Rangie and it had no problems, but it never ended up on it's side.

just other people that use it have had issues on angles with oiling probs

If you use solid lifters you will need to have very good tolerances in the rocker gear or something will go bang, will be a bit lumpy and maybe not the best for vehicle that will mostly be using low down torque to propel it.

Geez anyone would think it was black arts or something.
Holden V8 lifters are the same dimensions as Rover ones. Get some solid lifters for a Holden.
If you have a P76, you can drill holes in the lifters similar to the P76 ones. You may need to machine the lifters around the waist.

You will need some method of adjusting the tappets. P76 have bucket tappets. You could drill and tap the head to put adjustable pedestals/ mounting bolts on each tappet. I bet Holden parts would fit.

Finally you would need a solid cam grind . They are quite different to Hydraulics and you would probably get excessive acceleration on the ramps, and hence valve bounce using a hydraulic cam and solid lifters...
A lot of hassle but still I bet miles cheaper than a dry sump.

Another idea. You could get one of those "oil pressure reservoir" thingos from the US. They have a strong spring attached to a piston inside a tank. You can set them to give oil pressure on startup eg drag racer or to start pushing oil in on loss of oil pressure.

Or you could just run the Hydro Lifters because non of the buggies we have built with rover V8s have really suffered from this problem. I cant remember a time when my buggy has had a problem other then when its been on its roof for a few minutes. And even then it comes good within a minute or so.

Gday Das

i would have though that coz the lifters are under pressure and as long as they are getting feed that the lifter its self wouldn`t be affected by angles .

It`s only a suggestion but i would be looking more at the oil pickup because if it`s not picking up oil i don`t think it would make much difference which lifters , the solid may not rattle but may need constant adjustment as they wear coz of lack of oil .

Only ideas .

Give Darren at Mcnaughton Engine recon a ring on 02 49501640
He's in the Newcastle NSW area and builds P76 hill climb engines, he should be able to set you right.
