Ticking noise listen hard

[2006wrxtr]

Took the car for a drive after changing the plug. Made a pull in 4th gear to about 5k. Now I hear this ticking noise. Sound like it is coming from the drivers side valve cover.
oil pressure normal, temp normal, Fuel pressure normal...
Car always made a bit of valve train noise this seems to be the same sound but louder...
Here is a video of it listen hard and towars the end and let me know what you think.

does it have adjustable rockers? if so i would try readjusting tem all otherwise it may have a collapseing lifter

[2006wrxtr]

Broken poly lock is what it is.

Yea sounded like a rocker coming loose. I know been giving ya some input (and hope there working) but just wanna say that is a damn kleen car ya got.:thumbsup

I have run cranes,PVS, scorpions, comp cams, Proforms, and I can say that a lot of the rockers ya buy hold up but the Polys on some of them are sheet.
It coulda been worse, thank god for roller lifters. if you didnt have the spider on the lifters it coulda popped out and coulda caused some damage. One thing I do is put a dab of red thred locker on them after I clean the stud with brakekleen. Since its a hydraulic lifter you dont need to reset them for a loooonng time. So once there set there set.Ya can break the Poly even with the red stuff on. I Have had circletrack cars turn 7000 RPM consistently and they never came loose.

What was up with the car dying on ya?

......G' Damn thats a kleen car.:)

maybe i just cant tell from the vid, but sounds like its puffing too? like running on 7 cyl? Fell down on power too since the noise came along? check the plugs, it may have clipped 1 or more.

[2006wrxtr]

Well I replaced the one poly lock that I found broke and still the noise.
Guess what? I found two more that are broken.

How much of the stud should go into the lock? Mine are only held on by 4-5 threads. Is that enough? The locks are breaking right where the lock nut is.

Could the valve train geometry be off?
This is so frustrating...

[RanJer]

Oh no!! You didn't have your motor built by Forest did you?? :eek:

I have no input here, I'm just bored.

[badass88gt]

Get ARP stuff.

[2006wrxtr]

Get ARP stuff.

that still doesn't answer the ? if I have enough thread to hold on..

[juicedimpss]

its bent to have about half of the height of the poly lock threaded into the stud.
you may have a pushrod length issue.

yeah that is kinda what I was thinking. Going to pull one and compare it to the old ones that were in it. I think with my cam the stock length would be fine. But I can call Anderson on monday to make sure.

[badass88gt]

The only way to know is to measure. Do it right.

Anderson cant tell you with 100% certainty what size pushroud YOUR engine needs. Way too many variables decide that number.

yeah I thought the shop that put the engine together would have done it right...

[badass88gt]

You can check the pattern very easily without tearing into it. That will tell you where you're at.

Here's a write up. This article is on a Chevy engine, but it will work on QUALITY engines too....lol

thanks for the info......

[Brian98GTP]

I have a brand new pushrod length checker I'll sell you... :)

I'd measure the PR length on your own, add in whatever preload is recommended, and then check the wipe pattern to see if the geometry is correct.

yes that is what I am going to do. I really just want to put it through the shopd doors. I shouldn't be having this issue if they did the job right.

[Sprayaway Fox]

Since you have to take off the rockers anyways and doing it correct. See if your rockers are hitting the retainer side. A lot of cheaper rockers you have to shape the pocket so the retainer has a safe distance when its going up and down.

[2006wrxtr]

I used a dry erase marker to check the wear pattern on the valve tip here is what I got.
this is with the factory push rods in

Trickflow pushrod 6.8"

Looks to me like the trickflow is just to long.
Let me know what you think?
Thanks, mike

Stock length looks good, though the mark looks a little wide, the position is fine.

Get yourself some new rods that are stock length and you should be set.

Have you checked side-to-side alignment on the rockers, meaning are they centered on the valve tip or off to one side?

[2006wrxtr]

They look pretty centered to me. what does it mean if they are off to one side a little bit?
How long are the factory pushrods?

[MurphysLaw88GT]

is it 6.272? for some reason that # sticks in my head

[badass88gt]

Murphy's is right on the stock length. You want the rocker tip centered on the valve tip, you dont want them hanging off of 1 side.

I think the heads I have were cut a couple thousandths does that make a difference for the push rods?

[badass88gt]

That is one of many variables to pushrod length. Just go by whatever length gives you the best pattern, then order some hardened pushrods in the correct length.

[Brian98GTP]

Yes, having heads milled will affect pushrod length.... however, I don't believe pushrod length makes any difference at all with valvetrain geometry. If you change the pushrod length and nothing else, all you're basically doing is changing the preload on the lifter.
The height of the rocker fulcrum centerline in relation to the valve stem tip dictates the wipe pattern.
