NO!!!!!!!!!!!!
If you do you will bend pushrods or break the lifter!!!!!!:yup:
THAT IS SOME 60's SHIT!!!!!!!
Please explain this, some manufacturers recommend it. Filling them with oil is more or less the same as those already in the car. How would you bend a pushrod?Quote:

You should use this on top of your pushrod and on your valve stem as well to prevent a dry start.
If you soak a hyd. lifter before installation your making it a solid lifter!!!!!
It is made to be filled with oil pressure from engine WHILE RUNNING!!!!
It will bend a pushrod or even break it if it is stock junk with pressed in ball because something has to give........You now made the hyd. lifter solid!!!!
it is made to also be adj. out of the box thats why it has a spring under the pushrod plunger!
ANY "REAL" ENGINE BUILDER WOULD USE ASSEM. LUBE AND YOU PRIME THE OIL PUMP UNTIL YOU HAVE OIL IN ALL PUSHRODS!!!:yup:
I'VE ONLY SOLD LIFTERS AT THE SPEED SHOP FOR 8 YEARS SO I'VE SEEN PEOPLE DO ALL KINDS OF STUPID SHIT...
Have to disagree. GM manual says to lubricate with oil and when I replaced mine with comp oem lifters the instructions said to soak them in oil to throroughly lubricate the bearings. I soaked mine for about an hour, worked great and nothing bent or broke.Quote:

Apply moley lube to the lifter foot, smear oil on the sides and squirt some oil onto push rod seat. Maybe some people will disagree with some of that but it worked for me.

IF YOU DON'T WANT TO BELIEVE ME CALL 1-800-999-0853 WHICH IS COMPS HELP LINE!!!
JUST BECAUSE YOU GOT LUCKY FORCING OIL OUT OF BLEED HOLE WHEN YOU ADJ. YOUR ROCKERS................I'VE SEEN 20 CUSTOMERS BRING IN BROKEN AND BENT SHIT OVER THE YEARS!!!!:yup:
WHEN YOU SELL THIS SHIT EVERYDAY AND WORK IN A MACHINE SHOP YOU SEE LOTS OF MISTAKES........AND THIS IS A OLD WIVES TALE THAT HAS CAUSED MANY PROBLEMS OVER THE YEARS!!!
Here's the instructions from compQuote:

Thank you for choosing COMP Cams® products! We know you have options in valve train
component selection and we are proud to be your manufacturer of choice. Please read this instruction
sheet carefully before beginning installation and also take a moment to review the included Limited
Warranty information.
Pre-Installation:
It is important for all new roller lifters to be washed thoroughly with mineral spirits or parts washing
solvent to remove all assembly grease. After the lifters are cleaned, it is recommended to soak them in
common engine oil to ensure bearing saturation.

WHY DON'T YOU GIVE THEM CALL AND SEE WHAT THEY TELL YOU.....Comp. that seeing that I'm watching the games with there rep. for AZ. right now..........!:yup:
I GUESS IT NEEDS TO BE MORE SIMPLE ENGLISH FOR DADDY TO UNDERSTAND.....THE BEARING IS ON THE BOTTOM OF THE LIFTER THEY ARE REFERRING TO!!!!
The ? "daddy" was should I soak them in oil overnight!!!!!:brick:
NO!!!!!!
BETTER YET CALL JHONSON SINCE THEY ARE ONE OF THE 2 COMPANYS THAT MAKES LIFTERS FOR EVERYONE.......BUT YOU KNEW THAT ALREADY................
We are getting a little heated arn't we?
Could care less!!!!! Just been doing this shit for a long time and seen MANY people Fu_k up there stuff be hearing a wives tale from the 60's.......Quote:

I'm only trying to help the poster, and disagreement is sometimes part of it. Unfortunately, sometimes personal digs are too.:rolleyes:
Sorry Papi............:giveup: Just letting you know what I see EVERYDAY in the speedshop..........My Major was in :slapboobies: NOT ENGLISH!!!! Between running 10's and slapping nipples I could care less about proper english!!!:moon:Quote:

Hydraulic lifter oiling
From comp cams:
It is not necessary to “pre-pump” hydraulic lifters full of engine
oil prior to installation and valve adjustment. It is actually undesirable to do
so as the “pumped up” lifters will cause the valves to open during the
adjustment process, rather than positioning the valve lifter plunger in its
operating position as it is supposed to do. “Pre-soaking” hydraulic lifters
in a bath of engine oil is a good idea, but is not mandatory. It does ensure
that the lifters are adequately lubricated on their outer surfaces prior to
installation in the engine. It may also result in a quieter engine start up as
the oil in the bath may displace some air from
the lifters plunger reservoir.
Crane cams
When installing brand new Crane roller lifters, you must wash them thoroughly in fresh, clean solvent, allow them to dry and then soak them in the same oil that you?ll have in your engine.? The new needle bearing roller assembly found in any new roller lifters is coated with grease for assembly and rust prevention purposes.? This thick assembly grease can hinder needle movement and prevent the flow of fresh oil to this critical area upon initial start-up.? A few extra minutes to carefully wash these parts can increase the overall longevity of your roller lifters.
Also from Crane:
Prime a Hydraulic lifter? - Remember the guy who told you that you must ?prime? a hydraulic lifter prior to installation? The old story was that you should soak the lifters in oil overnight and be ?pumped up? with a pushrod by hand prior to installing. Don?t do it! This may cause the lifter to act as a ?solid? and actually prevent the obtaining of proper preload.
From Edelbrock:
Install the lifters using a high quality engine oil. Briefly
dip the lifters in fresh, clean oil just before installation.
Do not soak the lifters for a long period of time before
installation.
Well looks like your research brought you right back to my original answer.
I've been doing this for a long time like I stated and not going to throw out uneducated guidence.:cheers:
