Comp Cams installed, ticking noise, base circle problem?

FOXCOUPE · Jun 25, 2006

I just picked up my car today after getting a pair of Comps 262's and springs installed in my 99GT. As i was driving i could hear ticking coming from the right side of the car so as soon as i got home i opened up the hood and started listening. At idle it's not much louder then before but as the revs come up the ticking does get louder. I can hear it coming from the head (used the old srew driver technique) but nothing from the valve cover and yes the injectors are ticking but this is louder and only on one side. I did a search on this and found that a couple of years ago Comp had issues with cam base circles being out of spec but they were working on fixing it. Where is the base circle loctated on a cam shaft and how is this causing problems? I'm not capable of doing a cam swap so i have to pay to get it done. At this point i'm already several hundred dollars out now and if i call comp and actually get them to replace these under warranty i still have to pay more cash for another cam swap. Is there an alternative route? What about shimming the cam thats out? How is this done and what would be the down side of it?

Whats ****y about this is that this was gonna be my last mod casue i wanted to keep it simple with this stang. Just some basic bolt-ons and a pair of cams with a tune and thats it.....anyways any info u guys can share would help alot thanx.

Sounds very much like the timing is one tooth off on the pass side.
It is very common for the chain to jump 1 tooth on that side and cause a tick.
I had to realign the chain 3 times the first time I installed a pair of cams.
The tension on the cam on that side will make the chain jump until you get the tensioner installed and adjusted.
Get it checked and hope you have not bent any valves.

I bought a comp cams 270ah and valve springs but it's sitting on my closet for more then 3 weeks now. I cannot find any one to install it here in vegas. One place I found they want 1500 $ cause they said they have to take the head off and I know that is BS cause I have seen lot's of picture and video of cams install without head off.

I hove your problem is small , can you please tell me how much cams and valve springs install cost you ? Please

Thanks

the spring change will require either the heads to come off/ shaved reinstalled or you can use air to keep the valves shut and the Ford special tool to remove/replace the keepers.
I have believe it or not used soft rope stuck down the sparkplug hole, then gently rotate the crank so the piston pushes the rope into the valve to keep it shut.
When the spring is changed rotate the crank the other direction remove rope and move onto the next cylinder.
Sounds getto but is very effective.

i just installed my cams and they are doing the same thing my mustang shop told me it isnt timing and that you need to adjust the lash on the cams so im doing that this week it isnt hurting the car it is just gonna be noisy until you fix it

Yeah i'm hoping it's nothing major and can be easly fixed. Hey does anybody know what actually happens when the base circle specs are out? I mean whats making contact in a way it shoudn't where is the noise comming from?

Do you know how the cams were installed, did they degree them in or lock the cam gears in place using the Ford or Anderson tool and install them that way? If the cams were not degreed in, the issue you are having is the installer's fault and not the cams.

agreed.. This sounds like a install error to me. I would bring it back ASAP.

BS... there is no way to adjust lash on our cars. we have roller followers and hydraulic lash adjusters. as long as they are installed with the same follower you should be ok.

Don't know if they were degreed. I did bring it to a place that deals specificaly with Mustangs and these guys did some work for me before with no problems at all. I'll call them today and see if they did degree the cams and the car is definetly going back cause i'm not drving it around like this. Something else i should mention is that the car has idle issues now aswell.

Did they tune it also or just install and go?

FOXCOUPE · Jun 26, 2006

I haven't spoken to them yet but i've learned that to properly degree cams the motor has to come out and i know they didn't do that so as far as i know the cam are not degreed.

Did they tune it also or just install and go?

They did the install only cause i was planing to get a custom dyno tune done by one of the local tunner guys after.
