Windage Trays And Etc During Cam Break-In

I just want someone to explain to me how a windage tray, positioned between the oil and and the crank, and not the crank and the cam, can affect oil to the cam?

IMO, that is just INSANE, and makes zero sense.

If you allow that the articles are calling valley trays “windage” trays...that won’t matter either, because return oil flowing on the cam is probably less than 1% of the oil that gets to the cam.

Like I said, I can’t make the linkage that they are making.

I’ve said before, I have never removed a spring for break in. Ever. The last engine I fired off, I did. I lost a cam over the summer, and all I can attribute the failure to is a bad break in procedure.

So.....because I refuse to use slow, lazy, bottom end killing lobes, I’m going to cryogenically test every cam and lifter I use, pull the inners, run the pig for 20 minutes, install the inners and run the pig for another 20 minutes.

I’m getting old enough to know that there are way more failures today, and I think that is because the lobes are far more aggressive and we are exceeding the limits of the cam core and the lifter.

It wasn’t that long ago that you could buy hard face overlay lobes to keep this stuff alive. And that had its own set of issues.
