And you think it's the lifters that went south, not the cam?

 

so what do you notice when this happens? Reduction in power, flakes in the oil? Im running Valvoline Vr-1 which is supposed to have a lot of zinc to help fight wear like this, but it still has me worried.

 

The ones that I have found are from guys wanting to upgrade for bigger heads, or a bigger cam shaft. There were no audible signs of failure, nothing on the drain plug.

So if you're coming up on your 1 year manufacture date, pull it and inspect it.

 

I have access to my warranty information through GM. I found that I had all 16 lifters replaced in 2004 @ 31k miles, which was 2 yrs after I purchased the vehicle in Oct. 2002.

I asked a performance tech who I work with about the VR-1, and he said that it's a very good product. Matter of fact he had just purchased a six pack for $45. I mentioned that was a little salty for my wallet, and he then recommended an additive called TX-7 (http://www.polydyn.com/engine_treatment_information.htm). This can be added with an oil change.

 

So emailing my rep at comp on this issue I have sold a **** ton of cams lately am curious on what they say on the issue..

I'll keep you guys posted..

 

Buy that **** on Amazon. $31 for 6 quarts and free shipping with Prime.

 

I'll be curious to hear their response.

 

x2 me too

 

When i pulled the comp cam (212/218 low lift) with 40k miles on it, it looked brand new. This is with LS7 lifters and yellow LS6 springs. This was 10k miles ago. I plan on a cam swap in the next few months and will report back with my findings. FWIW i also run rotella t oil.

 

The result of Ls7 lifters, with dual springs on a Comp Cam @ 50k miles. (.228/.228, .588/.588, 110 lsa)
