Magnum lifter removal ?

[rustytoolss]

Is it possible to remove the lifters without pulling the intake ? Just asking . Thanks Also do you think roller lifter would need to be replaced with over 200,000 miles

No.
To remove the lifters you need to remove the spider and dog bones first. This requires removing the intake.

As far as replacing the lifters, as long as they haven't gone soft you should be good, at least with a mild cam.
New lifters or old, disassemble and clean them out real good before using/ reusing them.

That would be quite a trick.

Never had a magnum apart

Also, but I'm not 100% sure on this, you may have to pull the heads to get the taller roller lifters out...

Na, the stock rollers lifters come out without pulling the heads.

Yes it's possible, but you won't be able to get it back together with the intake manifold on and you may **** up your Spring Steel spider that holds all the lifter bones

Good to know.
I know retrofit rollers don't come out of a LA block (which have shorter lifter bores) with the heads in place, but I wasn't positive about the factory rollers in a Magnum. Never had occasion to try.

As a note, with Johnson Magnum lifters the 4 end ones won't go in with the heads on.

They can come out with the heads on but its difficult because the head gasket interferes with their removal but it can be done .

Thats why I made sure to say “stock”

How about some video proof. We can watch Richard do it right in front of our eyes.

It may just be LA blocks with aftermarket heads that they won't come out of. I've got Morel hydraulic rollers in my 273. Lifter bores are sleeved with sleeves maybe 1/16 above the top of the bores and my lifters will come out and go in with the heads on. I used 302 heads on my motor.
