FYI Lifter issues still persist. I rebuilt a Pontiac about 6 months ago. Cam break in was successful but about 40- 50 miles later one Lifter failed. I thought "screw this I'll use a roller cam setup ". $1800 later, now my hydraulic roller lifters are ticking.

[@andrewevans1658]

I own a Rockwell Hardness tester but the problem is that testing will ruin the lifter. The diamond probe will leave a dimple making it unusable unless the lifter is refaced.

Good video and thanks for the heads up KEV Cars have gone down hill since fuel injection 1983-1987 Time frame. And as you can see the Industry for hot rod parts is heading south also . Anyone who’s been paying attention over the past three decades has already seen this coming

Ken- thank you for sharing this, I am having a lifter failure and engine was done right by Paul Knippen a well know builder. Thanks for sharing this.

[@Obgmarine]

Thank you for your video! I recently built a sbc with a hydraulic roller cam but used solid roller lifters. I spoke to 3 different cam company's first and all of them said yes absolutely you can do that as long as you tight lash it. They all suggested. 006 to .008 Hot lash. Which in this Engine was .003 cold setting. So far so good!! Engine masters did an episode doing just that and the results on the dyno even showed an increase of about 10hp. I'm just happy if it lives a long life. I guess time will tell. Thanks, Mike

[@arlanmaxwell9932]

I am actually waiting on lifters for my build. Thank you for shedding light on the subject. May your engine light never come on!!!!!!

[@Moody.Trails]

IMO, the manufacturers are pushing away flat tapped cams and lifters on purpose with bad manifacturing. That way, they are promoting their more expensive roller cams, lifters and all other aftermarket parts, (Spings, rocker arms, etc.) needed for roller conversion. I am in the same situation. Soon, I'm gonna replace my cam and I'll pay extra for roller upgrade, just for the peace of mind.

[@Haffschlappe]

Government want no rebuild ICE engines

[@flinch622]

Well... typically two things lead to bleed down: plunger/body tolerances too big, or check ball assembly is not doing its job. So I arrive at an odd question: we really going to recommend hyd rollers from the same sources that cranked out hyd flat tappets that didn't work?

[@sidewyndersshed1676]

I have just rebuilt a 91 dodge 360LA ( factory roller cam) I decided to do something that would never have crossed my mind 20+years ago. I am re-using the 32 year old lifters. They have not bled down, and show minimal wear. I did disassemble and clean them. This for a slightly modified engine, for a daily driver, nothing extreme, I just don't want to tear it apart again.

[@closertothetruth9209]

i have seen similar issues on other US channels regarding recent lifters but havent experienced it here yet. Hydraulic rollers became my favourite as soon as i finaly learnt they existed as an after market product in the early 90's

Thanks for the videos. My EngineTech lifters in my Buick 350 chattered from DAY ONE. Luckily I don't think ive wiped a lobe yet... motor still runs good. But ticks away. Ordered two more sets and I'm praying I get a good set.

I can clearly see circular rings on the faces without the need for a magnifying glass. I told them they were defective. How much you wanna bet they'll rebox and re-sell? And that new camshaft? Already toast. Burned in 1K miles even though I was very specific about cam break in.

Ok I just had exactly what you are describing. Installed cam, adjusted lifter preload, followed break in procedure to a t and used break in oil. Next day I fired car up for test drive took it out engine started chattering. Just like you said lifters bled down. Ate the cam and lifters. Never had this happen in my life.

[@spmotorsportsmachine5645]

@@je862 i believe its more to do with the cams lobe profile not being ground on an angle, no angle no lifter spinning = chewed lifter.... did a 350-454 swap in a 72 vette, put two comp flat tappets with there magnum series lifters, both of them chewed the lifters up within an hour of run time.... 2000-2800 rpm varrying rpm up and down for 20 minutes. switched over to a howards cam/lifter set and 0 problems so far. only has 15k on the motor but he only drives it in the summer so. this will be his 3rd year and i got my fingures crossed they never wipe out lol. also the only reason i say that the lobes are not being ground on an angle, in my belief its due to 90% being roller with straight cut lobes, its like they forgot how to grind a cam

I just got wind of this about a week ago from a HI-PO engine builder. He said the exact same thing. That's a crying shame. Almost everybody has pimped out quality to save a buck, while screwing the customer. Dam!

[@tenthousanddays2103]

4 months ago I built a 375 hp 396 engine for a customer with a 65 Corvette restoration project. I used the comp Nostalgia cam and matching solid lifters. During the 20 minute cam break in it took out 5 lifters in varying degrees. The lobes remained, the bottoms of the lifters got chewed off. Peeled the engine down, cleaned everything out, got another cam done, nitrite hardened , and got a set of EDM hole lifters, thinking they would be a slower moving part likely to be older stock and thankfully it worked . So I would say that solid lifters are not immune.

[@snocrushr]

[@mickemmett6828]

This has been going on for decades, I remember changing a cam and hydraulic followers 30 years ago on a Vauxhall Cavalier, as soon as it warmed up and the oil thinned out the engine would stop due to the rockers no longer pushing the valves down as the oil ran straight out of them.

[@hectorortega9131]

[@donnatalielucasheimbigner7598]

I had a Ford3.8L V6 with hyd roller cam. Replaced the OE cam & lifters. 3 of the new lifters were bleeding down. Cam company replaced them, & 2 of those had issues. I swapped lifters to make sure it wasn't valvetrain problems & the issue followed the liters. The cam company was excellent & allowed me to use the old OE lifters after they were verified as good. ZERO issues with the old OE lifters with over 250,000 miles on them. Note that the oil was RELIGOUSLY changed with Castrol oil & an OE filter between 3500 & 4000 miles with the vehicle used about 70% on the interstate. But still, crappy new parts but good old parts. Thankfully they were not wearing out on the bottoms creating trash in the ENTIRE engine, creating the need for a complete tear down & wash up.

[@halseyknox]

I totally agree about the bullshit of being sold shit!....I have been stalled on completing my FE build for these exact statements and comments. Guess my option for my current lifter scenario is to have the ones I bought Rockwell tested or look for a set of N.O.S lifters and rebuild them and have the piece of mind....

[@anthonysoulard9938]

I bought hi-rev lifters from speed pro for my 318 build and sometimes they bleed out and rattles like crazy !

[@johnbradford2852]

Great info... there is one economical method to test hardness that involves bouncing a ball bearing off the part and watching the height it rebounds. I have used a balldrop hardness tester to see if hardened or not in my engineering career and can say that it does work... just dont expect to report an exact number since it is literally releasing a ball onto a flat metal surface and seeing how high it bounces. If you have a part that is known to be correct (aka a known "good" lifter) and the test part you can see the difference. You can make one by bouncing a steel ball bearing inside a tube from a given height on two parts and see the difference. I will be doing this on my new hydraulic flat tappet lifters on my BBC and seeing how high the old ones bounce as reference. Good luck to all of us playing Russian roulette with our engines.

[@nv1493]

So true. I decided on the extra bucks for a (retro) HR cam and lifters in my 454 rebuild for this reason. No guarantee on anything these days though.

[@The_Rudz]

Great videos Ken. While the engine is in the car, is there a quick way to verify if the rockers are out of adjustment or if there is an issue with the lifter? I have a faint tick or tap coming from the driver side bank. (350 chev, hydraulic flat tappet).

[@carlt6932]

If you can figure out which one is noisy push on the rocker arm on the pushrod end. If it springs up and down it is bleeding off. Or if you keep tightening and it stops pecking for a second then starts back it is bleeding off.

[@goldcat1844]

It seems like there is issues with hydraulic roller lifters too. I put a comp roller cam and lifters I'm my chevy 4.3 and it was fine for 30000 miles. Then I noticed some valvetrain noise. I found metal powder in the heads but very little in the filter. I removed the lifters and 3 of them fell apart when I turned them over. The cam looked ok but the lifters were disentigrated.

[@ChadDrake4185]

Just lost 5 of 16 lifters in 14 minutes on a Ford 390 FE. They were Sealed Power lifters and a Melling MTF4 cam. The lifters are too soft and I didn’t know to check hardness before I tried to break in. Also, one if the lifters collapsed and the plunger just ranked. I followed all breakin procedures and I used VR1 with Lucas ZDDP additive. Plenty of zinc. The Sealed Power lifters are total junk. I cleaned everything up and reinstalled the old Ford cam and old Ford lifters and it’s all good now.

It sounds like bad heat treatment on these parts. I know because I’ve been heat treating for 25 years and seen bad loads. I believe if these parts are being heat treated in China then quality is out the door and this is the end result. Most of the high quality aftermarket companies use American heat treat shops and things are done correctly. At least most of the time. If you want high quality parts use get your parts heat treated is a company with aerospace approve furnaces and employees. This will guarantee 100% that you will get high uniform strength through the part.

First step is put the name of the failed lifter here in these comments. Make, model, serial info. This way people know. Its a bit frustrating hearing people tip toe around saying the names. If its melling, crower, sealed power, comp, summit, speedway, jegs, howard, if its an ebay/amazon item use the store name and say it. Then whatever comes up most, its not the distributer, its the manufacturer to look into and follow up with.

[@gullreefclub]

The simple problem is that the manufacturer of lifters are being made basically by one or two makers overseas and the buyers (companies selling this junk) are doing zero quality checks of their own and not rejecting this substandard garbage and basically screwing over us the consumer. Both China and India business mindset is one of if no one complains and if they do discount the item and say sorry and they will never do anything to fix the problem until companies say sorry and discounts don’t cut it. The reason for the garbage parts is simple untrained work force and junk equipment being used to make the product in multiple factories that make a little bit of everything and don’t specialize in one area of manufacture

I could not figure out which lifter it was. Cam appears fine still has some of the black coating on the lobes. lifters bases showed still had slight dome on the bases..I took all the lifters out and opened and inspected all of them. I could find nothing wrong. they were all pumped up hard still and I had to put them in a vise with a ball bearing compressing them. all just bled oil out the hole but one it had some air bubbles in it. I am going to run a new set of lifters. what can cause the lifter to act this way. it had no miss and 50 psi oil pressure..? some said my oil pressure relief valve could have stuck temporarily and caused it to lose pressure, and damaged a lifter.. could one have just failed In the way I described? this has me stumped..I have good oil flowing from the oil galleries to the rocker shafts. Thanks to anyone that can offer some thoughts on this..Break in was fine with no noises ..

[@gregmaggielipscomb9246]

Sounds like to me you have a lifter that won't pump up or hold pressure, You will need to replace it if you can. You might try taking it apart and cleaning and inspecting it under good light and magnification looking for any defects, You may find it has/had a piece of dirt or some foreign material in it and servicing it might correct the pressure leak problem.Just remember to put some rev-lube on it when reinstalling.

I'm thrilled that you started a firestorm while this problem, It's total BS that we spent good money on a supposedly quality name brand company and get a bunch of Chineseium crap part,, I'm so pissed off about this and I think you for getting this information out to the public, I'm at the build stage of my 350 where cam choice is my next investment, now I hear this about junk a$% lifters,,, looks I'll go outside of my budget for a roller cam which is something beyond the intended use for this project but it's cheaper than screwing up a brand new balanced bottom end,,, insert screwing fit here,,,, drunk sailor style

I'm having issues on two 350 chevy engines lifter issues can't get them to stop ticking on new lifters smh 🤦 😤

[@davidreed6070]

I built a supposedly nice la engine It is now apart do to the rattling lifters from China. A took off a cover, cranked the engine. When I stopped cranking it, the lifters would bleed down within 5 seconds. Never seen this before.

Also got people that are just trying to get their vehicle back to a functioning level to be able to get to work and back daily.

[@tmags4661]

its now 2022, I put together a big Chevy with quality components, and it sounds like shit thanks to junk lifters. Gonna tear it apart and switch to roller. I wish I had seen this video before ordering and installing parts :( ...

We’re having the same problem.. Rebuilt the top end on a 5.8 ford Windsor, figured we’d do new lifters since we got it all apart, we’ve went through 2 sets of new lifters over 1/2 are bad. We’re going to be installing the original factory lifters!!

[@tractor629]

BTW, these are roller lifters, over half of them would bleed down right away and a couple wouldn’t pump up at all!!

Had a professional engine built for a jeep, Comp hydraulic lifters, it was built in Nov 21, its currently in the shop for suspected lifter failure after 3k miles.... just my luck

[@Mikes600r]

@@je862 so yes it was a bad lifter / camshaft.... they think the lifter wasn't turning as it should have been and the lifter wiped the cam.... unfortunately I do not have the camshaft or lifters, the engine builder sent them back to comp cams for reimbursement

[@Dannysoutherner]

Question is - is there enough flat tappet market for companies to bother with? It is mostly old car enthusiasts running flat lifters isn't it? People like me...

[@UcantBeSerious03]

thanks

It's time for a class action lawsuit

[@MikeyB_1972]

So much for my big block Ford 460 build for my cobra

[@ck4181]

Is the bleed down problem happening with roller lifters too?

[@electedsphinx4086]

Hydraulic roller lifters have the same internals as flat tappet like he said it’s 50/50 for each lifter to fail

[@lit549]

Ive had alot of issues with bleed down. My current engine is a "custom built" engine with all new parts, ls7 roller lifters rattle everytime i crank it. Builder claims its normal🤷‍♂️ 5k$ engine!

[@duaneafields]

First step is put the name of the failed lifter here in these comments. Make, model, serial info. This way people know. Its a bit frustrating hearing people tip toe around saying the names. If its melling, crower, sealed power, comp, summit, speedway, jegs, howard, if its an ebay/amazon item use the store name and say it. Then whatever comes up most, its not the distributer, its the manufacturer to look into and follow up with. If you keep getting bad fries at your Wendys, because they've been sitting, next time you go, ask for no salt fries, they'll make them fresh. Then ask for a salt packet at the window.
