- HOW TO VIDEO: Valve springs are one of the most critical, and most often overlooked, components in your racing engine. The incorrect selection of the racing valve springs is one of the leading causes of engine failure. In addition, many racers suffer failure due to the incorrect installation and improper handling of the valve springs. Watch Brian Tooley show you how to properly change the valve springs while the engine is still in your car.
Just got the tool, along with a btr stage 2 turbo kit in the mail a few days ago .. can't wait for my project to be running!
Thanks for the great customer service and great quality parts !!
Exactly what I needed to see. The valve seals being pushed down like that. Only video to have it!!! Thank you!!
"Hide the hammer from yourself" Man you got that shit right! I've botched a seal or two that way. I'm like lightning with a hammer. Never strike the same place twice
haha made my night with that comment. Thank you sir.
That is hilarious. "never strike the same place twice."
What a great video! Thanks Brian!
Awesome thanks for those couple little tricks guys
Best vid yet!
Sweet video.
With a ls2 na stage 2 cam kit, what is the life expectancy of the valve springs? ( street car) are there symptoms of them wearing? Much appreciated, and awesome tutorial videos.
Thank you.
How much psi are you supposed to run in the cylinders? Will a small pancake compressor sufficient enough?
When you press them are they is their room between the seal and the washer u put on the bottom or does it sit all the way onto the washer ...
I bought the cam kit with springs from BTR and just got it installed. I didn’t press down my valve stems but they set right in place like the stock ones. My oil pressure is lower now without the tune but I’ve heard a tune will fix it. If not would that likely be the cause of my pressure issue? Just wondering what others think this is my first project. Thanks!
How do I get one of those tools for me can you please let me know thank you much
What is the rope trick?
Thanks
ok what about installed height?
Preference between this Comp Cams tool and the LSM Tools version? I like both, just interested in your opinion, since you do these jobs daily (er, hourly, probably!) Thank you in advance, your contributions to the market are much-appreciated! ---==Temio Williams, Outlaw Performance, Yuba City, CA 95991
How much psi can you give the cylinder, I see you just hooked the air line up. But do you have to turn the regulator on the compressor down?
Just a guess here, but typically a car is around 120 psi when doing a compression check. That'll be a good start.
Awesome
What's the cost for this job if you take it to the shop range from
Hide the hammer! Good one! I try to not contact the engine parts with a hammer anyway, put something in-between, (and not to fingers) I hit the valve stem a few times like that, I started using a socket on the retainers!
what is the air pressure you put in the hose to hold piston and valve up compression?
I've been trying to find out the same thing!
If I run the stage 3 can what stall is recommended and will stage 3 work with stock pushrods
Why jeopardize all that work over $99 upgrade? Do it right, do it once
Hi, I’m looking for a valve spring compressor tool like the one is this video, that will work on a 2004 4.3L Chevy Vortec engine. I’m replacing the valve springs to fix a misfire issue. The engine is in the vehicle. My internet searches have all ended up with valve spring compressors for LS engines. I have bought two different brands of the “jaw” type compressors but they keep popping off the valve springs. I’m begging for help.
It being a 4.3 that's the same as a sbc gen1 style. Theres hundreds of different ways people change those. I changed the springs on my 400 SBC I use to race but while I was in college it sat alot and some of the springs on opened valves got weak. I just used the air to keep valves up and used the valve spring compressor tool to hold down the spring. u bolt it to rocker stud and press down enough to get locks keepers out. It was on a s10 blazer I had it in. Hope the best for u.
What is another method to keep the valves from falling. I dont have an air compressor, i heard of the TDC method but havent found videos that do them.
KASOR8281 here is a link. What I don’t like about this method is pushing up in the valve with the piston you are pushing of the edge of the valve. Myself wouldn’t want to do that. I picture bent valves. Even slightly is failure.
Learn to find TDC from watching the push rods and you can feel and hear the compression stroke on the cylinder you’re working with. Ensure using something to go inside plug hole. Then I would use the air. This way is something stupid happens with your compressor or hose or fittings. Your valves don’t drop into the cylinder. Which means heads come off.
Here is that link but I don’t recommend it.

String method
what size is that valve lock ??
Would a pancake compressor work with holding the valve up?? Thats all i have at the moment
I just did my springs today with a Briggs and stration pancake compressor and didn't have any problems
i am wanting to go with the btr stage 4 cam in my 2013 5.3. I am new to the LS world. what else will i have to change and swap to make it work? it is a bone stock engine now.
How much PSI to hold up the valves while doing this?
Did you find an answer for this?
@@lalonbs0092 I have done some reading and few people mention 100 psi
My order status says processing, it's been 5 days...
Where did you buy tool
They made it
I don't think I'd be using the hammer on the retainers either
When you press down on the seal should it bottom out on the top end of the guide or should there be a bit or room?
Did you ever find the answer to this? Doing an install now and wondering the same thing. The seal WILL NOT go down far enough to bottom out even with the proper tool.
@@isaachill3869 can you send a pic of what you're working on? Honestly I forgot but maybe a pic will refresh my memory.
@@charlesclemons741 I’m not sure how to send a pic. I’m installing new dual springs on LS3 heads. Everyone is saying there should be about 1/8th of an inch between the seat and the seal though with the new one! Does that ring a bell?
@@isaachill3869 that sounds right. I remember having to order additional seals because I destroyed some during the install. But that spacing sounds about right.
@@charlesclemons741 haha! I did the exact same thing!! I ended up ordering more seals and the btr tool for it 😂😂 thank you for answering so quickly! Cheers 🍻
How about yall includ 1 of those tools in the valve spring kits yall sale since you can't use the claw style tool cause that's the only 1 that can be found in a store
They can but that’ll raise the price another $60-$80 I’m sure for springs
Can't touch this hehe, hammer
Richard Holden get him a deal
Nice video. However, I would NEVER hammer on a valvespring like you did at the beginning. Then you say the first thing you want to do is hide the hammer!!! I don't care how long the keepers have been in, a magnet and a small screwdriver will always loosen them up.....
Rubber mallet works good and won't hurt anything.
Put a socket with a magnet in to give it a few taps works well on stock springs .
The claw type valve spring removers WILL NOT even almost damage your springs! You must be trying to increase sales of that over priced tool you're using.
Give us a call Anthony. You'll quickly discover we NEVER upsell anything to our clients for profit purposes. The tool used is an industry standard for LSx applications, and we stand by its quality and use for these cylinder heads.
Don't mind me, I'm just disgruntled that I have not seen one for the Ford 302 =)
F that claw spring compressor tool. I used one on a 4th gen LT1 build several years back. Got the job done but hated it.
Bought this basic tool shown and will be swapping springs soon to BTR’s .685 LS7 springs. Wish me luck. ;)
This tool is perfect for LS heads. I bought one and glad I did. Its really good on in car cam changes. Btr knows there stuff.
Try a Mallot.... NOT a Hammer😂
