Thanks Brother.
I just put new aluminum heads on my 350 rebuild, and realized that I had to install a weak valve spring to measure for correct pushrod length after having the block decked. The ol "rope a dope" trick looks good to me. 👍
Thank you so much for making and sharing this very informative video. I now feel more confident that I can change my valve springs without removing my heads.
Thank you for this video! I didn’t know how I was going to change my valve seals without taking off the heads!! You’re a life saver!
Glad it helped
Amazing!! Cool trick for solving this problem. Thank you sir for a well made demonstration.
Hey man THANK YOU SO MUCH you just saved me at least 6_8 hours of back breaking knuckle busting to replace an exhaust valve spring on #1 of an 2004 4.0 I6 jeep wj I just bought at auction for 600. Great shape other wise. I did comp. test 1st cyl. 65 psi all others 155-165. Once again THANKS FOR THE ROPE TRICK. Cheers from Jacksonville Florida
You're welcome.
Always appreciate your videos. Your instruction is clear and concise. Thanks!
Did new seals, springs, push rods and 1.6 rockers on my lt1. Your rope trick was great. I used small rubber tubing since I didn’t have rope but worked just as well. Thanks for the tip.
Very nice Broke a spring on my boat motor Im doing plan B method today Thx Dean
Great video, thank you for taking the time to make it.
Thanks, and you're welcome
That's easy to fix
Great video man! Exactly what I was looking for and really loved the rope method. Keep em up!
Thanks
Really appreciate it
Gettin a rope to hold valve up so I can see what spring to order tiil I get it.
The lever is only 9 bucks and it works great. The rope is the way to go!
Great video! Thanks for the little tips and tricks.
Thanks. Glad to help out
Great video.
Great video learnt a lot thanks
My headers are tight to the spark plugs and I need to use a box wrench on a couple plugs. For that reason, a compressed air fitting won't work. I like the rope trick a lot - it should work fine for me! Thanks!
Great video!
Very informative just put in timming chain in my 88 chevy dulley 454 block but learning to fix low compression?
Yeah that's easy to fix, just shave your head's on your motor
My goodness, man you explain that great.
Thanks
Thanks for the advice.👊
You're welcome
Great!
Hi, i subbed about a week or so ago. Been catching up on your videos. Enjoying them all! Might be a last gasp of winter up here in Minnesota this weekend. Then hopefully put K10 plowtruck away and get out my summer square! Thanks
Thanks for watching. 😊
Squarebody Stuff Plan B worked great on the boat motor. I have two bad intake valves springs number 1 and 2 cyl Went bad at the same time New one on me Thx again Dean
Glad it helped out.
Great vid buddy
Thanks
Never heard of the rope method, love it thank you sir
You're welcome
All three ways to change valve springs are great thank you !
You're welcome.
Thanks for the video! I think I've done the valve springs with every method possible, I personally like the compressed air method best because it's faster for me, but if there's no air, the rope is second best way, I also like the bolt on handle better than the twist-up spring compressor, because it's easier for my big fingers to get to the keepers, nor do I have to use grease to keep the keepers in place, but either way, both methods wil get the job done. I wonder how many inexperienced diy's didn't leave enough rope hanging out so they can pull the rope back out? Lol
Thanks for watching. Several different ways to skin this cat, but wanted to show how I do it. Not leaving enough rope sticking our is a good learning experience. Lol
Hey I’m going to change valve springs on a 350 chev and I’m just wondering how much air pressure I should put in the cylinder or if I should just leave it continuously pumping in like he did? Thanks
You'll have to have continuous air going to it.
If you put the piston at TDC, can the valve fall in?
Not sure if it's been mentioned in the comments yet, but using the compressed air method, it's best to do it with the engine still bolted to the trans in the car.
Put the cylinder at TDC, put the trans in 5th gear and then apply compressed air. Having the trans in 5th gear will help keep the engine from turning over, that way if you do drop a valve, it likely won't fall all the way into the cylinder and you may be able to grab it (depends on the size and shape of the combustion chamber)
Yeah the compressed air method, aka "the way the pros do it" comes with its own risks.
I have a triton 4.6 2004 ford expaditoon the Ford dealer found the valve spring in the oil pan now car shield is telling the to put and new valve spring on and the truck will be fine is this true
very helpful thx...
Have you had any problems with the studs pulling out say with a comp cams high energy 268 cam with 454 lift
Nope. Should be fine with that cam. The 268 is a great all around cam for small blocks and big blocks.
Nice video, I was wondering if that cheap leverage tool would work (1995 K1500, 350/5.7). What do you mean at 6:22 when you 'cut the threads' on the nut? Do you have to do this in order to use this tool?
You don't have to, it just makes the nut easier to turn . Or find a regular nut that fits.
Well it worked great! Springs replaced
Now the rope in a fucking stuck!
Do you know where to get that style of valve spring cap?
If I remember right. Those were some comp cams retainers and locks.
Is that cup you put on top of the spring called the retainer?
Yes
In a 4.6 Chevy, can one or two valves be changed, or does all the valves have to be changed? Thanks anyone. Just trying to do it myself, and not spend a lot of money.
You can change just the valves that are bad, but its a good idea to replace them all while you have it apart if the budget allows.
hi there ,
how you identify your valve spring need replacement?
If upgrading the cam you'll need the correct springs. If it is a high mileage deal then I use the when in doubt, change them out thought process. You can also use a spring pressure gage to check the spring pressure
Do you ever have any issues with shimming the spring height?
No
What’s the best way to know when to put your rope in (just before TDC) if you can’t see your crank because you’re pan is still on?
I like to use the plastic straws off of brake cleaner or carb cleaner cans to stick in the sparkplug hole to get a feel for where the piston is at.
@@SquarebodyStuff Ah ok. Good idea. Thank you. Any risk of damage to the valves or piston should you go past TDC with that little straw in there?
No, it's soft enough not to hurt anything
@@SquarebodyStuff Thanks dude 👍🏼. Do you have a video putting the rockers on and setting zero lash?
Yes, here it is.

Can you do this with the engine in the van?
It's a pain, but yes.
Ha ha ha ha ha ha
Did you measure or set spring height with shimming and measuring im getting confused on some say got to get the spring height set.
I don't worry about that on this level of build.
