Anyone using the 440 Source Hydraulic Roller Lifters?

[bremereric]

I am using the 440 Source Hydraulic Roller Lifters bought last November...I had some problems with them when testing for pushrod length....I heard a click as I rotated the engine and then I could push the plunger in very easy with the pushrod...I contacted them via phone and they said all would be fine when the engine is primed..I wrote them an e-mail last week that they did not respond to.....wonder why?...I started the motor today and shut it down right away....sounded like collapashed lifters on both sides....engine oil pressure was good...when I rotate it with starter trigger no noise...no vibration felt on top of valve covers when rotating the engine....what do you think before I tear the top of the motor off? :clock:

Have you figured out your problem yet. I hope it wasnt/isnt serious. Has 440 source got back with you, they better I'm watching to see there response and i'm sure others are too, Im getting ready to purchase some heads and a stroker kit and I wont use them if they dont stand by there products. Good luck.

Check to see if the oiling band on the lifter rises above the lifter bore at max lift on the cam lobe.

My cam is only like 540 lift with 1.6 ratio rockers force the valve open about 577. I put one of the lifters back in the bore on a cam lobe that was almost at it's max lift....the oil holes are below the top band and it looks to be okay?

top on motor already taken off....

The top of that band should be a good .040" or more below the top of the lifter bore at max cam lift to keep oil in the lifter and in the crank and rods.

Their stoker kits can't be beat, some of their lower cost products need some modification for example..... I had to grind a little off the end of my distributer for it to fit in their bronze distributer gear....I had to also take some off of the other end (shaft) so that it would slide easy into the oil pump....

Kim Burns with 440 Source called and listened to what all I said, he admitted to the recalls last year and thought they had fixed an oil blead down issue, as it stands now I will take them out and await an RMA number for them...I did also order some Comp Cam BB roller lifters from Alantic Speed....they had them in stock.....$528.00 versus the $300.00 for 440 Source's...that's why I went with theirs....lession learned again...cheaper is really never better than more pricey...

My buddy Paul runs a higher lift cam than I do and he has been running Comp Cams hydraulic lifters for a year with no problems.....on another thought8)

I got my RMA number from 440 Source today so the lifter will go back Wednesday....I did slip a set of lifters back in on one of the cam lobes that was almost at top height and the top oil band had plenty left in the lifter bore...I plan on making a comparision to the Comp Camp lifters when they arrive before shipping back the 440 Source lifters...8)

Sounds like an internal issue then. Good to hear that are going to RMA them and stand behind their products.

How long does it take for the lifter to pump up? Aren't they filled with air, and the oil needs to displace that air before they are solid? Can this be accomplished by priming the motor before start up? Are the lifters pressurized with oil all the time, or only when on the base circle, or something like that?

If you prelube the engine properly, and the preload is set properly, the lifter will bleed out any air in a few seconds. I am glad they are taking care of you on this.

All instructions I have ever read states that is not needed to pump up lifters before installation, most do however suggest that you place them in a oil bath only for lubrication purposes....I pre-oil the motor with an 18 vdc Dewalt drill and rotate the engine at the same time with a remote starter trigger...I did this once Saturday and then again Sunday right before stabbing the distributer and starting the engine...starter it three times and the lifter tapping noise was so bad that I only let it run 10 to 15 seconds at a time to prevent any damage...Kim's comment was quote "that they had thought they hade corrected an oil bleed dwon issue"...end quote 8)

I got my Comp Cam roller lifters today and what a difference.....first of all the width of the top oil band is wider...thus the oil hole is about 1/8" lower....I think 440 Sources oil bleed off issue was due to the narrower top oil band and the oil holes being higher........also take a look at the pin that secures the link bar....which would you rather have...cleaning them up to put the motor back together....will keep you posted on the progress....can't wait to fire it up again...8)
