Most of you consider yourself knowledgeable in cars.
I thought it would be fun to post some automotive tools to see if anyone knows what they are.

This special tool is not home made, it is available through a commercial company.
Anybody know what it is?

Sheesh...a wing nut, a carriage bolt and something taped to the end. Somebody actually takes credit for producing such a thing?

Yup, and it is truly ingenious

Spare tire hold down...know that isn't a tool. So this has to be a device used for measuring something.

.....for aligning something....

(wot's the prize?)

Club admiration for your great intelligence and good looks

Gonna have to settle for great intelligence...

HINT: one end is a very powerful magnet

I think that just made it more confusing...

OK, the give away hint:
There are 16 of these that you use all at once

Oh hell! A lifter puller-upper for changing cams without pulling the intake manifold in a V8. Are you serious?

Good job Matt

Let me dig through my toolbox for the next challenge

Sure, but what the hecks the wing nut for?

Butts against the cylinder head to adjust the "reverse pushrod" length.

Exactly, the magnet grabs the lifter, you pull it up (but not too much), then you snug the wingnut against the head or guide plate to hold the lifter up. Then simply slide out the old cam/slide in the new cam all without removing the intake manifold. Saves several hours of work and an intake gasket set ... the tricks of flat rate mechanics ...
