Need to replace valve spring, don't know exactly what it is

[Vettezuki]

So kdracer73 help me sort a problem I've been having and discovered that one thing is for sure, I have a busted intake valve spring on cylinder 6. I know they're not stock, but can't find any record as to what exactly the are. I'm cash poor and would prefer to replace just that one at this time instead of all 16. How do I determine the correct replacement?

Check with the guy who built the engine that you bought it from. If he doesn't remember then I would go with what ever is recommended for the cam.

[enkeivette]

I'm pretty sure they make a spring pressure checker. You can just measure the diameter, measure the spring pressure, call comp and see what is closest off the shelf.

I'll look for the pressure checker. I remember Norvalwillhelm talking about it I think.

[enkeivette]

Is it a beehive or dual spring?

[enkeivette]

If you want to do it super cheap, enkei style, take off a good one, take it to a machine shop and have them measure it.

To keep the valves in place, move the piston up to the top for safety, and fill the cylinder with compressed air from the spark plug hole.

Thanks for the tips. I'd like to get this sorted this week if possible. I haven't driven the Vette since Ortega.

The issue with testing the old spring is that it will be weak (less spring pressure).

[enkeivette]

Which is why when he picks out a spring close to the measured pressure, he should move up on the scale.

[enkeivette]

But I doubt his relatively new springs will be that much lighter anyways. And if they were, it would be better to match what he has right now anyway.

Kinda what I was thinkin'.

Dual , BABY !!:laugh:

[94cobra69ss396]

What cam do you have again?

[Throttle Crazy]

Can you take a picture of it and text or email it to me?

[Throttle Crazy]

I called by friend over at CBM motorsports in Rancho Cucamonga and he said if I send him a picture he could probably identify them. If not he can pressure check the other valve spring on that same cylinder and match the spring.

[Vettezuki]

I'll post a pic tonight.

??? I don't get it.

...That's what I have.

I feel your pain brotha, that was the last time i got to enjoy the stang :(
Soon to come, a 95 snake eater :D *cough* Rons car *cough*

You can beat me right now because your car is lighter so it would be easier to push than mine. :lmfao:

[Vettezuki]

Maybe we could have like a box car derby and see whose car is fastest rolling down a hill. :huh:

[Vettezuki]

What cam do you have again?

224/224 114LSA .566 max lift

Basically it's small/moderate, but the biggest you can put in a ULEV (2001 Caamaro) vehicle and still pass the sniffer.

[enkeivette]

Three of the most common posters on here have dead cars right now, how funny.

PS. I'd win the soap box derby. I run synthetic in my diff and gear box. Also, I'd bring an oar. :P

Haha, actually Ron would prob win. He doesn't have a 4 decade old IRS.

[94cobra69ss396]

The Chevelle is still running.

[enkeivette]

Haha, ssssuck it!

Make that 4.... my trans is broken !

Emailed.

[Throttle Crazy]

I sent him the pics. He will call me back later. I also asked him if we popped the spring off and ran it over to him to test the pressure, is there a chance he would have one laying around. Do you have a compression gauge or leak down tester to put air in the cylinder and a single valve spring remover? If not you can borrow mine. Air up the cylinder, take the springs off, put a couple zip ties on the valve so it can't fall and take the air back off until you have the spring.

[kdracer73]

Dual , BABY !!:laugh:

Is it considered dual, if it is in two pieces ? I didn't look close enough the first time !:nutkick: Other ones I've done had dual. Now that we got it off, I know it is single.

[enkeivette]

Eek! I saw a 4 speed laying on the ground under a... nova? Down here at the pick your part in Chula Vista.

There are a few 80s and 90s F bodies in the stanton pick your part too. Get a T5 and make it work! Should be cheap and easy.

It is a 4 speed (auto)

For 900 bucks including 2800 stall converter , with upgrades, I am gonna get it rebuilt.

I don't want a manual trans....am I getting old ?

[Vettezuki]

I just remembered I have a set of beehive spring take offs from C5 ZO6 heads. I had Troy at Ford Performance Solutions test hte spring presure for me to see where I was at. He said the one I gave him off my head was at 120lbs and the Beehive was at 100lbs (virtually identical over the nose whatever that means.) he thinks I wouldn't have any trouble just using this.

Whattya'lls think? Maybe I could sell the set of ZO6 springs and buy at least the correct (matched replacement).

enkei, thanks for the link to the set of Lunati, but that's out of the question now. Phil's buds shop has sets of hi performance springs for like $140. If I could get $40 for my ZO6 springs . . . *maybe* . . .I'd buy a new full set, but I'd generally prefer to spend a penny right now.

Here's a pic showing them side by side. Click to make ginormous.

I was just showing an example of dual springs sold under that title. Just throw the Z06 springs in there. If he told you they were virtually the same rate, valve float shouldnt be a problem.

If you turn up with S shaped pushrods like Ron, I was wrong. :D

Yes. Haha. Autos can be fun, if you have enough hp.

[Shaolin Crane]

Ben i can ask my engine guy if he has any 120lb springs laying around

That'd be cool. I do like consistency where possible. Got your text. Now that's for 120lb single coil LSx springs?

[kdracer73]

How about some triple springs ? Might require some more mods though.

These came off a Pro Stock car.

I meant put all of the LS6 springs in there.

Thanks to Paul again! That fixed up the basic problem. I changed out the t-stat though and it seems it's running hot. I'll start another thread for that one.

Also, thanks to Shaolin Crane for hooking me up with a set of valve springs at VERY low price. I broke right now, so things tend to sit if they ain't cheap.

[Shaolin Crane]

No problem mang ;)

My pleasure ! Glad I could help :thumbs_up:

Don't forget to tell Chuck he's full of it.

[kdracer73 had a manual valve spring compressor, no leverage. His mechanic pal Chuck told him it'd be easy enough to push the springs down. Ha! It took both of us on a count of 3 to get enough force to compress the spring far enough to lock it. If I had to do this again I'll be borrowing the LS head spring compressor which just bolts in and has a lever.]
