Them roller tips are not heat treated like the more expensive ones. And check your valve stem tips for groves. If you find dips on them, then put some harden lash caps . 😊
302 Ford is as reliable as a hammer fix may be a PIA but you’ll get it. Beautiful car!
If the sound is coming from one side , then switch the flat spot rockers to the other side and if the tapping noise goes away then you found the problem. Stethoscopes are @ 10 bucks a must have in your toolbox and they work just like the ones the Doctors use on you.
Awesome 😎, I’ve had a problem with this style of roller rockers before. I solved it by replacing the whole set. My buddy just tore down his new sbc with new comp roller lifers, and cam, with less than 100 miles on it. He found 10 of the new Comp cam lifters broken. I believe that 99% of the parts were getting are junk before we ever get them.
You are 100% right these companies don’t take pride in there parts or work anymore or they are so money hungry they move there companies out of the country where quality goes down the drain
Sometimes in the lifter itself, the cup that holds the check ball and spring inside the lifter comes out of the bore causing the lifter to lose pressure causing the tapping sound. It is always a good idea to disassemble the lifters and inspect them
Never hurts to thoroughly inspect every part before using.
Takes less time than doing it over, 1, 2, 3 times. 😱
Happened to me!! I replaced a couple lifters that were noisy and the tapping went away
It’s going to be the rockers , especially with flat spots.
Damn fam this is all that ppl need for content.idk man. This is just like being there working on your car with you. Talking about all this stuff and just being good. Ty for all the extra knowledge. I know for a fact the next time I'm running into lifter noise that I will be remembering the video and looking for what you just went out of the way to show. That would be what I call a pretty cool dude a good friend or whatever. We obviously don't know one another but I'm just glad to have something to look forward to a couple times a week. Keep it coming
This sounds like a typical Canfield Head valve geometry issue. They moved the valve locations from stock slightly like the highport. You either need the correct guideplates or better yet a rocker with an offset cup like a shaft mount design. I have these heads on a twin turbo fox body cobra.
When I had these on a NA 302 engine with a Z303 and Motorsport stud mount rockers, the valvetrain made noise but cut 1.62 60ft on motor in a sn95 heavy cobra. Those heads prepped right will absolutely fly. For the foxbody cobra, we took a basic shaft rocker and machined the pedestals to align with the valves to eliminate the guideplates completely.
That’s exactly what I was thinking. I’m going to modify the guide plates and see if I can get proper pushrod and rocker alignment
I've ran those same rockers and they didn't last, even tried trick flow and scorpion rockers and they have failed. Out of the many rockers I've used the only 2 that worked great with zero issues and that have lasted was the Harland Sharp's and Comp Cams Molly. Some of the other ones had ears from the snap rings break off and get into the oil pump and locked it up twisting the drive shaft. Also a great idea is to make sure your oil drain plugs have magnets built in and stick an old speaker magnet to your oil pan to help catch any metal that may work its way to the pan.
😎Glad you mentioned magnets👍
I like em on the oil filter too.
You'd be amazed 😲😲 what they catch.
With only a magnet on the drain plug you can see what's happening.
I’m having the same exact problem with my link bar lifter and brand new rockers! Eagerly awaiting the follow up video!!
My plans as of right now are to before setting each lifter preload, use a drill to spin the oil pump. Make sure each lifter is fully pumped up
The black 04 wheels look mint on the calypso
Man your channel is awesome 👏 I just got my first fox and the calypso is looking like how I want mine to look like mods wise I plan on eventually painting mine the strawberry red later on keep up the awesome videos!!
🔔😎 That sleeve on the TB is a step that is ruining airflow. You'd have to see it on a flow bench to believe how bad that is.
Beveling/tapering the air filter edge helps @50 cfm. Beveling the inlet edge of a stock TB adds 70 cfm.
Think what airflow does.
JMO..... OCD 😁😁😁
All autos have that tap guys.
Hey bud. Love your channel. Dig your passion for foxbody stangs. keep up the education for the young folks. And for some of us old guys also.
Could be so many things. One of the best ways I’ve found to figure it out is with a dial indicator on top of the suspect rocker and just the usual suspect. If pushrod length checks out then you are left with lifter, rock, and (hopefully not) valve guides. Another possibility is a valve tip that is shorter. You can take all the rockers off and run a straight edge across the top and make sure they are even. A tip I can give if you use a dial caliper to take some measurements is to wait a second after tighten back down the rocker. It can take up to a minute for the preload to show in the indicator. This makes you think right after you adjust it and it’s tight that all is good but while you are putting everything back together that lifter takes the preload and the measurement changes after you’ve moved on.
good catch on that stick, flat spotted rocker, Id go ahead and replace them too!
@brew2l what rockers did you order? I have always had very good luck with Scorpion Endura Race rockers in my engines. They are still affordable and Made in USA still 🇺🇸 I also toured their factory when they were in Ft. Lauderdale. Very impressive.
Hell Yeah
From what I see in the video… I agree that it is VERY likely the Roller Rockers. Definitely good thing you took the valve covers off and checked them considering the other issues you found! Shows how important it is to address engine noises as soon as possible. 💯👊🏾
I’m hoping 🤞
@@BREW2LFOXBODY Me too! 😬
Those rockers are trashed. Even if it were only one, the other 15 are close behind.🙄
Great video man hope you get it fixed in time
I chased this problem for weeks. Ended up being the oil galley plug at the top of the block under the intake manifold on the back china rail. I was getting low oil pressure readings too. Not sure if your getting low oil pressure.
I would look at setting the lifters dry to get lash perfect . If you haven’t yet it has always worked for me . Having them full of oil can cause the valve to hang open a little bit .Then prime them . But I’m sure you know all that . I hope to see you at FordTakeOver. I’m planning on being there!!
I set them dry the first time actually. See you there brother
Appreciate the information, I was not aware of that!?
I only use the pushrod twisting method on hydraulic lifters.
When you feel them drag, then set your preload.
JME/JMO 😎
I have a set of those rockers with the same problem ..
I feel ya ..when I got my motor back together I had to adjust mine twice n I think I have one lite tapping probably going back in.
I hate rocker chatter the worst! 😡
If roller rockers tick new, they're shit immediately.
Strong springs ruin rockers.
Face it.... RPM causes repeated repairs.
I have a tick on the passenger side too. But I'm running new push rods( stock length) and new roller lifters. Stock pedestal style so they just get torqued down. Tick will come then fade then come back and fade. Any suggestions?
What heads are on that engine? I had cheap Procomps and the engine, clatter for years. Finally changed them for a different set ProMaxxes. Still has a meshing sound but with the aggressive cam closing rate it's nothing like before. Can hardly hear anything with the hood closed.
I put some 1.7 proform on and couldnt get them to shut up. Chatter chatter chatter. Car ran perfect but sounded like a sewing machine. Ended up going to the scorpion endurance rockers so they would clear factory valve covers. Looking forward to seeing yall at FTO. Thanks for the content
Yeah those things aren’t the best. Kinda hit or miss with them.
• I Love All The Advice & Tips You Give In Your Videos Man, Currently In The Process Of Swapping Out Head Gaskets On My '89 L.X.
You've Helped Me So Much Man, You And Foxcast & Everyone Else Deserve More Recognition Keeping These Cars In Motion, I'm 22 Yrs Old And This Is My 1st Car ‼
Man this makes me happy hearing that! Keep the torch lit 🔥
@@BREW2LFOXBODY especially with the younger generation!
hope the head gasket swap goes well and quick so you can enjoy your foxbody this summer!
@@BREW2LFOXBODY • Thank You 'Sir ‼
NEVER SELL YOUR FIRST.
I did 56 yrs ago. Regretted every day.
I have my Son's high school car from '90.
Restomod 63 Fairlane Fox fuelie T5 etc.👍👍
😎
Yeah I think you are on the right track, I would most likely suspect problems with those lifters, and should be
replaced before it takes out more parts, very wise you decided to replaced them if they feel like they were sticking.
And the one with the flat spot, was a concern.
Man you keep talkin bout ford takeover.. i wish i could go! And its not that far from me either 😕 but i got a ticket to the tooth fairy.. and this one dont leave change, just carries a bfh, a pick, and a set of pliers. I hope its a great show for those that get to go tho. Not mad, just jealous 🥺
Some noise that I thought came from my value train ended up being a hose that touched the header. Hope everything gets better soon.
Oooooohhhhh looks like ProForm rocker death! Literally chased the same noise, and it was those cheap-ish rockers
I hope that’s it. We’ll find out tomorrow 🤞
Hey I was wondering I have a 1986 5.0 Can you adjust the original rockers
I love how you did the tail lights! Bad Ass
Thank you but the previous owner purchased them from LMR already tinted.
🔔😎
Add valve lash caps to take up for pushrods too long.
Get a GOOD set of rockers.
Remember strong valve springs ruin rockers pretty quickly.
IMO if you get 20,000 miles from cheap rockers you're really lucky.
Good rockers are close to $400.
😎BTW
check EVERY part before you install them.
That bad polylock should have been inspected during installation.
You must have OCD when installing stuff.
🙄
I strongly prefer at least 8 oz of Lucas at every oil change. It actually does help reduce wear on those high friction areas.... Pushrod tips, rockers, etc.
THINK.. if you've got 300# spring over the nose, that's about 480# on the pushrod tip's tiny surface area.... Which is about 2,000 pounds per square inch... And your turning that thing 6,000 rpm.
HARD ON ROCKERS ????
What size the MAF and intake pipe please⁉️
Shoot everyone is scrambling.... Dropping my heads off tomorrow at the machine shop... New set of head gaskets and new tune... hopefully it will be at Ford takeover if not bringing the daily 🦊
I love the grind!
idk what to do with my EGR vacuum emissions stuff idk if that's my leak
I Really liked my Erson roller rockers 🙏🏼😇😎🌅
Are you going to the lmr cruise?
i adjusted my 1.6 scorpion rockers with trick flow springs on gt40p heads 3 times and it still won't stay running without raising the idol to like 1200
the second time i adjusted it. they started making that noise. i was told it was just lifter tap and to use marvel mystery oil and it will go away but i didn't try that yet.
but i need to get it running right. it's been months and i don't even want to look at the car anymore lol. i'm pretty sure the rockers are still good. i don't know what to do.
i had a thermal heat gun and number one cylinder isn't as high temp as the other ones. think it could be number one spark plug or wire. and they all vary a good amount in temp. anyone have any ideas please let me know
i was also told i might need my injectors shaved down since i have the explorer intake on
1/4 turn past lash will chatter 1/2 turn past lash on base circle stops the chatter normally. Those rockers are probably shit!
I’m still working on the schedule for Fordtakeover, but it’s not looking good at the moment. Hopefully we can get everything done, and make it to the event. I can’t wait to see the Carbon 🦊 and meeting you in person.
I hope you get it sorted out brother! I’m pulling for you ✊
@@BREW2LFOXBODY thanks Bro 😎. I might just have to drive the daily, and stop in for a little while, and then head on to Arlington Tn to my Daughter’s to stay. lol 😂
I think your on to something. If nothing else, new rockers would be worth doing. Love the content as always!
I hope so. We’ll know for sure tomorrow
Joe Steve Gowan if you know him, told me to crank the adjuster down 1 full turn after 0 clearance and lock it down, I was skeptical but when a legend speaks I listen, haven't had a single issue and I've given it pure hell.
Damn 1 turn? I might have to try that
@@BREW2LFOXBODY yeah I was scared. Lol, but it worked great. But it was after draining/compressing the lifters. With pumped lifters it might be a different story.
your cam manufacturers generally have a recommendation to secure the lock nut past zero lash. Most recommend from 1/2 to 3/4 turn.
@@pimpovic2 yeah I know, but the guy that told me 1 turn builds race engines and is the race winningest builder around, so I trust him.
@@RedHammerBodyShop 👍Anderson used to recommend 1 turn on their cams and they changed to 1/2.
I went with the Trick Flow 1.7s!!!!
Great rockers ✊
Hey brew2L, is your fuel line at the rail missing the safety clip??
Many are.
Never hurts to safety wire everything.
(Airplane mechanic 😁😁)
I should be at ford takeover, hope to see you and the carbon fox!
Nice! See you there!
My lifters have been ticking since rebuild about 4 years ago and get less when it warms up
Have you tried thinner oil?
@@BREW2LFOXBODY the car used to run on 2050 I put 10W-30 in it when I change the oil this time. But everybody tells me the Ford racing lifters are known to tick. I use my stethoscope and everywhere I touch on the valve cover has the same ticking noise like all the lifters do it but they do quiet down some quite a bit actually. And if it's really cold outside they are a little louder but like I said they quiet down after it warms up.
@@BREW2LFOXBODY I forgot to add they are hydraulic also
@@billpace3489 same here, I was running the comp cams short travel lifters and it was quieter after I would make a pass or get on it real good, im not so sure if it was the heat in the oil or they were bleeding down too quick at idle and needed high rpm and oil pressure to pump up fully?
@@vrm86gt I didn't build this motor so I'm not sure what's going on. I'm not that much of a mechanic. Can I Street raced many many moons ago I had a great mechanic and I've never had a car that lifters tick unless there was an issue, but the car still does what it's supposed to do and when the turbo kicks in it still feels like everything's right it's just scary here and ticking.
You definitely found an issue with those rockers get rid of them it's not gonna get any better also that Polly lock is junk do yourself a favor and check your pushrod length get some new ones and definitely a new set of rockers
Roller rockers ordered
Hey Buddy great video I jst want give you and everyone else a heads up i had bought new Ford High Performance roller lifters (not the OEM style) I had 8 that would not pump up. i had to order another box and 1 of them was missing the 2 keepers in the top that hold the lifter together.
Oh hell. Good info
Yea i was having same problem keeping rockers adjusted and knocking.
thank you for all you do brother you are a great motivator keep up the great work love your fox bodies hopefully I can have mine as beautiful as yours one day! See you at FTO brother
Sounds like something is sticking. Like a valve guide holding the valve or a lifter getting stuck in its bore.
I'll stick with my crane cams 1.72 rr that came factory on 93 cobras. Yeah I have a brand new set in the box from about 8 years ago lol!
I wish mine was as easy as pedestal mounts… 😡😳😂
When you get lifts above ,510 and springs around 280# over the nose, stock lifters are limited. Then 6,000 rpm. 😲😲
Beats the shit out of rockers quickly.😎
John, those 1.7s are ok even with HO cams, but when adding high lifts and springs 🙄 ouch.
Remember what they were designed for. Low lift/ pressures with the sled pivots to last 109,000 miles
Not for race engines.
@@hotrodray6802 That's true!
35
I think your lifter bores are wollered out and causing the lifter to chatter at idol
