Are there things on cars you just can't understand?
I've got a clear idea of how an engine works, except for hydraulic lifters. I know what they do. I've pulled them apart, cleaned them, and reassembled them plenty of times. I know what all the bits look like. I've read the manuals and looked at the diagrams. But I still can't quite grasp how they work. Don't bother trying to explain it, because I know the theory. For some reason I just can't convert it into a working model in my mind. I've got a better idea of how black holes work than lifters.
there are a lot of things on cars i can't understand... pretty much anything under the car, or under the bonnet remains a mistery to me. i know how things work, but the details elude me to this day. i guess i don't pay much attention and can't be bothered.

Clutch-based LSDs. I get viscous LSD's, but not how LSDs with clutches work. ALso, i'll probably get bagged for asking, but hey, i'm new to this all, so, what is a stroked engine? I'm assuming its not simply one that has an overly amorous owner. Also, i'm not fully down with automatic transmissions (the dual planetary gearing confuses me).

I understand "stroked" to mean increasing the stroke (length of travel) of the piston to increase the amount of fuel/air in and compression, with obvious results. Don't know if it means something else as well.
And I have absolutely no idea how an auto trans might work, nor the least desire to find out. Never owned one and don't intend to.
To me a mystery - when they stop working, I buy another one from the wreckers. Especially when Escort ones could be had for $50 ono. I've pulled em apart, studied drawings etc, but they still make no sense.
Aaah, as long as it works - or replaceable, not too stressed about them.
L8a,
Prud

easy.... big gear, little gear. There's nothing to them....

Anybody else have this problem on anything?
Funny thing you mentioned abotu lifters, was talking to a few people about them and people thought i was on drugs when i said they exist in Inline 6 OHC Falcon engines. But gotta admit i can't picture it how they work.
As what a few people mentioned an overhead cam engine is driven by a gear and and a cam chain, some how the lifters are still there from teh OHV days. :oo1: :oo1:

Strictly they're called lash adjusters on the OHC as their function is related to, but different from the old pushrod lifters. See, I know everything about lifters, except how the bloody things actually work.
BTW, OHC and pushrod are both OHV (overhead valve), as distinct from old side valve.
