I know somebody knows..........:banana: I would imagine its tighter coils towards the bottom, but I need to know for sure. I dont feel like having to replace the head again.

Oh heres the picture of the tighter coils towards the top:

 

anyone... I need to get my head together.

 

I can't say with 100% certainty but I beleive the tigher end of the coil goes underneath the retainer. The looser side goes on the head surface itself.

Someone correct me if I'm wrong but I think that's right.

 

Thanks for the reply man. I appreciate it. If someone could verify that, that would be cool. I just would like to know 100% before I go slapping things together.

 

I will look at mine today before I do the valve seals and post back.

 

No, the tighter coils go down, against the head.

I have a nos original head out in my garage that I used to verify, I will try to get a pic.

 

 

Well, I never noticed this. I just put a head together for my 1G. They have to be up and down becasue I never looked when I installed them...Oh well I hope it does not change a whole lot...oops!

 

Sweet. Thanks for all the replies. That yellow mark must be the enamel coating the service manual mentions, it must be all worn off on my springs.

Thanks!

Correct

 

Does it really matter???

Ya, the spring rate will vary a lil more with it the other way....But how much?

Is it enough to have to take apart the head and re-do it?

I didnt even look at mine, just tossed em on.

 

I don't think it would really matter but who knows. If I had put them on without noticing and found this than I would leave it alone personally. If it has a problem it shouldn't break anything, just have problems running correctly.

 

IT matters alot in all reality. Think of the weight difference between the tight wound and loose wound coils. If you have them upside down it WILL float the valves because of the inertia would be higher. Get them put in right side up or you'll be doing it later.

If anyone wants to argue this matter look into Comp cams Beehive valve springs they're designed with a smaller coils at the retainer for a reason.

You nailed it. My stock EVO8 springs are bee-hived as well.

 

I just went out and checked my disassembled head. I kept everything in it's proper order. You are in fact correct, the tighter end goes on the head and the looser end goes to the retainer. I stand corrected. I tried to apply logic and apparently it doesn't apply.

 

Ahhhhh Shit. So, I'll be the one who asks.
What will happen if i don't rememdy my fuck-up?

I didn't know they had a specific direction. So I just put them on too.

The car runs, but like poop. I think because of the disconnected (not plugged) vaccum lines, incorrect fuel pressure and n/a ECU.

But bottom line. What will happen?

 

Your car will blow up, and you'll end up like White91TalonTsi.

What WILL happen? Probably nothing.
What COULD happen? Increased likelihood of valve float. You have put the heaviest part of the spring on the end that gets shot up and down thousands of times per minute. Think of it as the opposite of getting Ti retainers.
