My comp spring broke after 3,000 miles. I have been hearing a ticking sound over the past few weeks, and the engine has been running rough. I thought it was an exhaust leak (since my EGR was leaking were it connected to my headers). I stripped off the EGR, blocked it, and I still had the sound. After checking the plugs, and header bolts I finally pulled off the valve cover and part of the spring had snapped off. I can send anyone pics who wants to see it, since the file is too big to upload.

Supposedly these springs are good up to .600 lift, but I guess not.

 

sigh 918's... sigh...

 

Just curious, have you been letting the car warm up to operating temp before doing any hard driving?

 

Yeah, I always let it warm up if I'm going to drive it hard. I'll even let it warm up for average driving.

 

Comp had a problem with some batches of these springs. You may want to look into it.

 

Actually I just read in a recent thread that you can call comp, tell them your 918's were bad and they'll send you a new set of 921's or something like that, someone please clarify

 

thats what you get for buying something made in mexico

 

A buddy of mine works there and he told me the same thing

 

...welcome to 2006. 918's FTMFL.

 

I broke one too over a year ago. They replaced it for free and wanted to know what batch it came from,box number, etc....

 

Just bought a Vengence cam and Ron doesnt use the 918's due to that reason, a bad batch. Comp gave them a different spring which is so far holding up fine.

 

You're suprised?

Swap in a set of PAC-1218s or PAC-1518s and be done with it.

 

Call Red at Comp Cams (warranty manager type) and tell him about your issues. He'll get you taken care of.

XBROKEX - Are you kidding me? I guess you'll never want to run a caddy race lifter, L92 heads, and a whole SLEW of other parts from GM on your car. Heck, you should probably start tearing into your car now and rid yourself of such parts....you might still be able to roll down the road, but I doubt you'd have combustion!

 

you can call chris mays also at comp. they sent me their new 918s (old 928s) as a replacement for free this week. little better specs on the new ones.

 

You mean they sent you the 928's as a replacement for your old 918's? CompCams is good people. Call them.

 

I will call over there and see what they can do for me. I have an order in for PRC Dual Springs right now, but if Comp can replace them, I'll have to cancel that order.

 

Did you happen to note the Batch number from the box by chance?

My car has some recently installed 918's, but no issues YET...

 

I just spoke with Comp and they are awesome to deal with. They are sending me the 928s as soon as they get them through QA. They also let you choose between money towards the install cost or titanium retainers. Great people to work with, they took care of this immediately.

Oh, and my batch number is 054524. I guess there have been a few others from this batch, but not as many as other batches.

 

Good and Bad news for me...lol...

Good that they take care of you.
Bad that my batch number is 052xxx
