LSx oil system nuances that the SBF didn't have!!!

[Terry Oxandale]

I'm not an expert in the SBF, but I've built a lot of them. So when I chose the LSx motor as a powerplant for my project, I figured there would be some degree of re-learning... but jeez, when will it end.

Last week I swapped the clutch pilot bearing out for the Porsche unit, and once that was finished, I moved on to another task. Today, simply by happenstance, I read about a welsh plug that is inserted into the rear of the LSx motors, into a hole that is otherwise open to the crankcase. No big deal I thought, until it dawned on me that the "hydraulic" method of removing a pilot bearing may also push this plug through the crank counterweight, and into the crankcase....which it almost did. I pulled the pan, and there it was, still in the hole (barely), so now I've got to go ahead and push it all the way through, and re-insert a new one into the outside end of that hole.

I can't imagine what I've not learned that will come back and bite me later.

you don't know what you don't know....

Reminds me of:

[T]here are known knowns; there are things we know that we know.
There are known unknowns; that is to say there are things that, we now know we don't know.
But there are also unknown unknowns – there are things we do not know, we don't know.
