Camguard Use

[1TJ]

Ed, this is a thread hijack but since you've been looking at all of these components and oil analysis results, do you have any opinions of which new parts available today for Lycomings provide the best chance of a long, happy life?  I'm about to start my overhaul after Thanksgiving and will likely source a new cam and lifters, and I wonder about the materials, heat treatments or other post-processing steps, for the cam and lifters at a minimum.  I know that Lycoming has recently switches to a "hyperbolic" lifter and I wonder why they did it, and if it offers any advantages over the straight barrel.

 

I'd also love to hear your opinion on the possible merits of the Ney Nozzle or Centrilube mods to address Lycoming cam lubrication in conjunction with an Oilamatic preoiler rig.  To me, it seems like combining one of the cam lubrication mods with the preoiler would go a long way towards reducing the distress on Lycoming cams and lifters.

 

I've got a case of Camguard that I'm ready to start using again, but I'll be down for a couple of months...

Thanks in advance!

I do not recommend the Ney nozzles or the centrilube cam. Neither of these offer any benefit at startup and the cams will have made hundreds of revolutions before receiving any oil from these mods. They only supply oil when there is pressure and the nozzles only spray when the oil is warm. The preoiler has some merit but it is not worth the cost.
