So , you have every answer on what it ISNT, but cant say what it IS? I thought you have yet to recieve the lifters from tim, but how do you know the bearings arent showing signs of heat ?

Im pretty sure you know the answer, or have a strong opinion on what caused it. But, saying it, might cost you some sales .

Just what oso needs, more sales guys and politics. Did you dogn up here to give tech insight, or just to tell everyone how superior your product is?

I did some googling like havoc40 suggested, and stumbled on this topic where on another site they were comparing johnsoms vs morels . Here a guy claimed his "swedged " axle came out of his johnson lifter.

Well it's clearly the LIFTERS fault. Not sure what the debate is about.

Lol it may not be a lifter problem or a camshaft maybe a block problem. Maybe the lifte bores are on the wrong plane from each other. Nobody from a company is going to say what they think here. That's why he said everything needs to be inspected.
Yep he will not want to come back.
