Re: Time to Speak - 26918 Spring Failures Hey Stan it was cool talkin to you as well. U should do the cam. The smaller the cam the less cahnce of them breaking.

Re: Time to Speak - 26918 Spring Failures I got my T1 cam & 918's towards the end of May. They seem to be fine so far.
If anybody in the Houston area has one fail and would like a metallurgist to look at it, I can take it out to the refinery where I work and have one of the metallurgists there look at it. They will be able to tell us what the failure mechanism was.

Re: Time to Speak - 26918 Spring Failures Yeah, thunder seems like people who work with ya. but Im thinking of rather than worrying about it (even if I got a replacement) just going with another spring. The isky's have been suggested to me.

I got my replacement 918 from them after mine broke, so they know about some of the recent breaks. Jason works there so i know he's filled them in on the breaks.

increased spring loads will be required. COMP Cams 977-16 valve springs and COMP Cams 875-16 Pro Magnum hydraulic roller lifters are strongly recommended.
This was discussed when the XE-R lobes first came out and then people to decided the 918s were adequate.
BTW, I'm not here to support COMP. To me it sounds like a bad batch of springs. However, I point this out to those in the market for a cam now who may have forgotten, or been unaware of, the debate over using 918s with XE-R lobes.

Re: Time to Speak - 26918 Spring Failures It looks like Comp is consistent. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> Knock on wood, I've put 1,300 HARD miles on my 918's with no problems. These were bought/installed in early April. We're starting to use the new Manley springs here at the shop. Only time will tell how well they hold up, but so far so good.
