bleeding lifter?

[SFRacingGST]

Saw this on VFAQ after I installed my 3g lifters. Wondering if i should take them out and bleed them like they say to do below. All i did was take them out of the package, apply assembly lube to them and installed. The cams spin freely as is. My question: Am i going to have issues (bending valves) because i forgot to bleed them? Please let me know your oppinions and what you have done and how it worked out.
Thanks

Pull the lifter out of the head by hand (pliers shown for clarity)
Remove all oil from the new lifter - this also applies if you are cleaning and reusing the old lifters. Get a large paperclip and straighten it out. Insert it into the top hole of the lifter until it bottoms, then press on it lightly - you can now easily collapse the lifter with the paperclip still in place. If cleaning and reusing the old lifters:
Submerge the lifter in cleaning solution (brakeparts cleaner, carb cleaner, acetone). Soak it for as long as you can, preferably up to a day or more.
Insert the paperclip, depress the internal valve, and pump the lifter up and down until it moves freely and the fluid coming out is clean.
If you have the time, repeat the above at least one more time.
Remove the lifter, turn it upside down, depress the paperclip, and pump the lifter until no more cleaning fluid comes out. Set the lifter aside to dry for a while.
Submerge the lifter in oil, depress the paperclip, and pump the lifter to fill it with oil.
Remove the lifter, turn it upside down, depress the paperclip, and pump the lifter until no more oil comes out. This will leave a thin film of oil for startup.
The lifters will clatter for a few minutes at startup when empty like this, but that is better than having them too full of oil and bending some valves.
Drop the lifter back in the bore - it doesn't really matter how you line up the oiling holes in the lifter, they rotate under normal use.

Have you started the motor yet? If the lifters were full of oil they would bleed down to normal height within a few hours of being installed, so you'll be OK

I just have the head torqued down and still havn't done timing. im guessing i should take the extra step and do it. But i turned the cam by hand a few times after assembling the head and it seemed fine. Any suggestions?

My advice at this point is to stop worrying about it.
It's only dangerous if you turn over the motor immediately after installing lifters that have not been bled.

When I pulled my new ones out of the bags, they were full of fluid, pumped up and solid. If they were that way after sitting on a shelf for who knows how long and after shipping, I don't trust them to bleed down when I drop them in

I drained the fluid from them, pumped them up with clean oil, and then drained that before dropping them in their cozy new homes.

Personally, I wouldn't take the chance for something that only takes a couple minutes. But then again, I tend to be overly anal sometimes

Just my .02

EDIT:

oops... re-read and realized you already installed the cams... so I dunno. Pneumo's got more green than me, so he's probably right

Not to bring this thread back from the dead but I have two sets of 1g style lifters that have sat in brake parts cleaner for two days and not one of them (32 total) will move one bit. I put a paper clip in there and it goes in about 2 or 3 inches maybe. What am I doing wrong ?

Wiggle the paperclip around. There's a second hole deep inside the lifter, the paperclip needs to go down this second hole. You'll know it when you find it since the lifter will compress easily.

If you still can't seem to get them to move....You could do what I did, but I think its very risky...Take a paper clip and get it completely bottomed out and then bend the paper clip so that it forms a 90 dergee bend....Then turn the lifter upside down with the paper clip still in it and lightly tap it with a rubber malet...I had the problem because I left them in brake cleaner for almost a week... then Oil for a week as well... Happy bleeding

Listen to this guy! He knows what he's talking about.

I've had lifters that don't want to bleed down on their own. The last time I put the head on the RWD I ran into this. The lifters that correspond to lobes on the base circle are the worst, the ones that are slightly open self-bleed more better since there is some pressure on them. I had to pull all the lifters and bleed them before I could install the head. I went many years never bothering, but I started doing it with the EVO (did probably a dozen cam swaps in that car), and I now feel it's 5 minutes well spent.
