Removed head, pistons looking bad
Well due to a failing head gasket my 4runner was leaking coolant out the side of the block, anywho tore down the motor with the help of my girl friend and this is what it looked like
and corrosion where the coolant was leaking...

aww... c'mon. thought you'd have pics of the girlfriend turning wrenches and stuff.
just kidding....
anyhow.... that's just wierd. you can still see the crosshatch pattern in #3 (last pic).
don't worry. I'll be rebuilding an engine right beside you.

Can't really tell, but it looks like carbon build up to me. Not something to worry about if it is that. Just pour some solvent (I heard brake fluid works well) on there and let it sit. Should remove it.
None of my girlfriends ever knew what a socket wrench was.

look at the intake runners (looks like #2 and #3) in the pic below.
brake fluid might clean up the carbon problem on the pistons (not likely, but okay), but not the oil in the intake.

looking at that, I bet you'd find worse looking crap on the inside of the upper intake manifold, and on the back of the butterfly valve on the throttle body...
go ahead, take a look, I bet you'll find the good ol nice black goo crap; I can tell it's hit you too form the one pics and being able to see inside the lower intake manifold a little bit
EDIT, ha, I was right... you post too quick man...

I've been wanting to add one of those, but I'd just assume change the PCV valve every other oil change rather then empty out collected oil every couple of weeks

if they were serious about it, they'd use centrifugal force to cause the oil to collect on the outer side of the chamber, then drain the collected oil down into the crankcase, not the valve cover.
a simple separator like in the pic above wouldn't do anything to the aerosolized oil

I think the intent is to re-burn the oil to it acts like some of that top-end conditioner that "Lucas Oil" sells.. kind of seals the valves and rings a tad if you're running it hard enough to blow out through the PCV system.
Either way I dont like it either.
