LT5 Hydraulic Valve Lifter

[A26B]

Thanks to the technical expertise and research by our very own Pete P. aka "The Greek", the best lifter available for the LT5 engine has been found. Pete measured many valve lifters to find the one that most closely matches the OEM lifter, Melling JB 2236. I have edited a drawing to compare the OEM to the Melling, in such a way that can be better understood.

Jerrys Gaskets now stocks the Melling JB 2236 under PN 17120991. Our price is better than most and very close to the best we could find. If you need new lifters, we would appreciate your consideration.

Ah! Many thanks Jerry and "Pete the Greek" for the info! (Now maybe I can get off my dead arse and complete my article! Stay tuned!)

Jerry,

The Mellings are the ones Pete used on my motor with the intake cam
regrinds. You can see from the pics that I have posted the lifters are in excellent shape after over 2500miles on them.

What would be really nice, is for someone with excellent technical writing skills to assimilate all of this into a procedure from valve stem height to preload, with incremental steps & photos. Paul, is that the article you referred to???:worship:

I thought once I got the cam timing I could work with Pete on that, I took some intials photos and did some testing when I got my regrinds

[A26B]

I think it would be good to do the Tech Article based on stock cams and then insert a special section specific to smaller diameter base, reground cams to insure the preload calculations and the procedure are clearly depicted and not left to interpretation of instructions.

I would also suggest that the draft of the Tech Data Article is reviewed by a few experienced members or builder/tuners. It's not uncommon to see things published/released that contain errors and confusing commentary.

The Solutions Section is an outstanding source of information but it contains revisons on top of corrections and can be difficult to read and retain it all to get to the bottom line. It's a living source that does need to be reviewed and edited constantly to "weed it out" so to speak. But that's a subject for a whole 'nother thread.

Yep! Zackly!

AND...W/ your permission, I'd like to use your lifter diagram in the article...Beats sectioning one, "fer sher".

I have some photos of cut-apart litters that might be useful. I need to do a bit of photoshop work first, then will send them to you & let you decide.

By all means, use the lifter drawing if you want.

As always, thanks Jerry (Pete and others too) for this info. For the layman folks like me that don't understand all the technical jargon yet, what does it mean in reality since I rebuilt my motor with the Sealed Power HT-2236 parts?

[XfireZ51]

Cliff,

I am sorry to see that this has developed into a adversarial situation. I can tell you that I had originally purchased the Sealed Power lifters from Rock Auto on the recommendation of none other than Marc Haibeck.
Marc uses these on his rebuilds. However when I brought them to Pete for the reground intake cam install, Pete gave me a call to say they would not work due to clearance issues. That's when I got the Mellings, which was Pete's suggestion from the outset. Who knew? An SBC lifter is an SBC lifter right?!
As Pete says, the LT-5 is a very finicky motor and you really need to know her little quirks, which guys like Marc and Pete certainly do.

When I ordered my Intake regrinds from Pete he also recommended the Mellings. I found a great source for these and passed that back to Pete and to Others as well... Now they are even cheaper than the $10 a piece price point.

[GOLDCYLON]

What!!! $10 a piece price point? So...how much for each lifter as I am not sure about price point?
So.....what is the source?


PM sent with the info

[Pete]

This is a first i hear about this.
Hope you all kiss and make up.

On Dom's situation the Sealed Power lifter would sink into the lifter bore too far,meaning the base circle of the regrind cams would not touch the lifter.
Those lifters will work fine for stock cams

Regrinds only have about .010 base circle.

Did you do a valve job at the same time? Lifter height has a lot to do with valve stem clearance. I received Jerry's lifters two weeks ago he had on his web sight and had to send them back (they were in plastic with no name but Jerry said they were identical to stock). Those lifters were also different than the lifter shown a couple weeks ago on his web page in appearance. Jerry's lifters had .030 inch less lifter height than stock (distance from unplunged plunger to top of lifter). Those original lifters Jerry sent me (he said they were identical to stock) would not work with a Pete regrind. I asked Jerry to stock Mellings JB 2236 lifters (which are in fact identical to stock) which he did and I received a week ago. Summit Racing also stocks Mellings JB 2236 lifters at my request. Pete uses Mellings JB 2236 with his engine rebuilds and they work perfectly and are most closely matched to the stock (original) lifters in looks and in measurements. E-mail I have confirms the discussion I had with Jerry as well as with Summit Racing regarding Mellings JB 2236 lifters.

The issue is simple. I received about 4 variants of the Sealed Power HT 2236 from Advanced Auto several weeks ago (all in Sealed Power Lifter boxes) and took a lot of measurements. In that shipment were 4 different variants of the Sealed Power HT 2236 lifters. Only two of the 32 lifters in that shipment were like stock lifters. I also bought a Mellings JB 2236 lifter from Summit Racing which was identical to stock lifters. (This is all shown on the third page of Solutions). http://www.zr1.net/forum/showthread.php?p=117492&post117492

In a moment I shall put those details (several posts) back up on the third page of Solutions. I have to edit those posts however as I took them down the other day because I have Pete's regrind cams in the mail and have to change the details in each post to accomodate the actual base circle diameter of Pete's new regrinds. The posts related to lifters and valve stem clearance are however within .010 of being correct as they are written now. I shall provide those new details this next week (including details using a stock camshaft) depending on Pete's camshaft regrind actual new base circle. In the mean time you can take a look at the third page of Solutions. http://www.zr1.net/forum/showthread.php?p=117492&post117492

Jerry has been getting some of my posts deleted lately (a post last night related to lifters) and I cannot be sure he will not get those Solutions third page posts deleted also. I think because I suggested he correct his web site lifter picture as well as the lifters he stocks to Mellings JB 2236....we shall see. Jerry has been making a lot of comments related to Solutions lately also and I cannot be sure that Solutions will remain that much longer either. I and Jerry do not talk any more I think because of the Lifter issue and then his blatent attack on Solutions and his verbage related to my third page of Solutions which he still has not explained. (see post number 7 of this thread). I guess there is a reason Jerry did not mention any of this in his first post of this thread. Which post Jerry told me in e-mail he would not post as an advertisement but rather send key rebuilders the fact he now stocks Mellings JB 2236 in e-mail.

I might also add that Jerry may also get this post deleted shortly. I do have a copy of this page on my computer and shall keep posting as fast as Jerry deletes untill such time I am banned if that is what it takes to make sure everyone understands the issues related to lifters. I called my post last night that Jerry deleted The new 360 deg camshaft. That is what basically happens if you get your valve stem clearance wrong or use the wrong lifters (or for that matter get a valve job done) as several can attest to on this Forum including Paul Workman who I also am no longer communicating with because of the same issues. These guys just do not want to talk about rebuilt engines that they had to remove and rebuild because of this oversight or the fact they do not know the details of the lifters they sell.

If the administrators of this Forum ban me I shall just post this on the other forum because I happen to think it is very important but so far not discussed technical information related to LT5 rebuilds.

Cliff,

Yes, my heads received a valve job at the same time by a person that I consider a professional and all the precautions were taking by him in regards to valve stem clearance, seals, etc. as well as confirmed with lifters and also knowing that I had regrinds from SGC. He worked with Jerry on getting the correct seals as there are issues with those too. They were in communication between the designer of the regrinds and the person working on the heads (GVD). I'm not going into all the details, but will say that I have stock lifters (original) other than 8 that were replaced with the Sealed Power units all identifical to the stock units. When the camshafts were degreed in everything seemed to be in check and the car runs great. Only taken to 7K RPM after break in and held together so far.

As for all the badgering and accusations, your posts are quite annoying to say the least. I hope that all can be resolved and forgiven or forgotten in the end, but no need for these issues to get personal or ugly in public. Jerry has always been to me and a stand up guy as well as others like Paul so I find it hard to accept here between these friends. I consider you a friend too even though you are quite new to the organization and have made significant contributions since. I appreciate your information as always, but it confirms the need for some clean technical articles as Jerry suggested since it is confusing for use information coming from threads and posts as recommended. These have their use no doubt, but so much valuable information that would be great in a more organized manner for use by others. I hope you can find some peace in all of this and take a good look at your posts with some reflection.:handshak:

As a small business coach, I can tell you the dumbest thing Jerry could do is screw people on this forum. He's a good businessman and
an LT-5 enthusiast.
