[Healeys] 100 lifters

[Stephen Hutchings]

I had my cam ground by someone that Michael recommended in the Toronto area, and they sent me to another place to have the lifters re-surfaced and hardened.
So, after this, I now have about the same number of miles on my engine (6000), so , while I’ve had no problems, I’m thinking I should take apart the valve gear and look at the lifters…I’m wondering what led to your investigation of the lifters, Michael?

I have been driving the car to build up some trust in it and it's turning in to a joy to drive. I've got M mods on this engine, cam, H6 carbs, M pistons and these new lifters. So far, so good.
