... Even better would be a drilled camshaft that would have small
oil ports in the lobes, or even right next to the lobes, to get the
lifter faces wet.

But anyway, what's the common wisdom on preheating. Granted, in an ideal
world, preheating is probably a good idea anytime it's below 40, but it IS a
pain for those of us who are forced to tie down outside and have no access
to electricity. At what temperature point are you comfortable starting
WITHOUT a preheat? (If it matters, this is for a Lyc IO360 that will start
easily down to about 10 deg).

Any mechanics care to comment on what they have seen happen to engines which
have routinely been started cold?


I have sump heater that will keep the oil warm. I keeps the rest of the
engine moderately warm. I will plug it in when the temp drops below 50.
Sounds a little high? well If I can keep the oil warm and reduce the
stress on the engine components at startup I will. Easier on the starter
ring gear and the case (IO-540).

I suppose these guys have a patent on that cam so that Lycoming
can't use the idea in factory-new or O/H engines without paying big
royalties for it. It's about time someone did it, though. Glad to see
it's available. Lycoming should have done it themselves a long time
ago. Surely it's not because they didn't think of it.
