Now here's where we get to play stump the 9er and pretty much everyone else on the planet, 'cept for yours truly, since these are all home-boy specials made in the deepest dark wee hours of the mornin when nothin else in my bag of tricks would enable me to "Get R Dun".

The 2 on the left have similar, yet opposite functions of one another, which problee won't help much, but I mean really, this is WTF are these, yakno clown

The one on the right I'll just straight up give away since there's no way anyone is liable to get WTF it is other than a custom made 1/4" drive tool I made for one lousy exhaust manifold nut on my old Talon with a 2.0 Mitsu engine. This nut was located in such a weird position that I couldn't get on it straight with even a 1/4" drive ratchet and socket, no matter how hard I tried so I came up with this very short drive tool that was really only long enough for the 12mm socket to fit on it.

In later adventures with this same fastener I had access to my wobble socket extensions that let me get on this nut with a short 3/8" 12mm socket, but that night I was in a shop away from my main set of tools and just had to make do with a cuppla pieces of 1/4" key stock, a saw and a welder, so .... grinning

I have custom built and fabricated tools too. Some of 'em look like they fell outa the tool bag that woman astronaut lost in space while working on the Hubble.

Without seeing other angles it is hard to tell, but the two on the left look like adaptors to allow a socket to be driven by a spanner rather than a ratchet, or between imperial (standard) and metric.

GAK, these aren't sockets, though from this view, that's a good guess. They're made out of solid rod stock gently massaged into shape with the help of a lathe at about 3am, after which I welded the nuts on 'em so I could use a 1/2" X 12" drive extension on 'em in conjunction with a 3/4" socket on one and I think a 15/16" on the other to use as driver and installer tools as I was tryin to get my ride pieced back together.

The question is, what was I driving and installing confused

May have been the freakin' space shuttle for all we know. I've got tools I made for just one stinking project, which entailed the use of mills and lathes and mig welders because (1) the correct proprietary service tool was unavailable or too expensive, (2) No such tool exists anywhere on the planet for the operation at hand, (3) A large hammer and chisel are outa the question, (4) but may be effective in a fit of rage.

I wish I could say I'd managed a ride on the space shuttle, but I never did get to slip that one under my belt, and looks like I never will now either .... sniff, sniff. But ... remember I said I was tryin to get my ride back together.

Think bottom end of a Mitsu and a performance mod grinning

BTW, though I'm not immune to fits of rage, age and wisdom has shown me it's usually cheaper to just walk away, fire up a cig and ponder the problem rather than start flailin at it with my 3lb ball peen I affectionately call "Baby", hell, from time to time I even sneak it a mooch .... I'm kinda odd like that spinning

Timing belt tensioner tools, 4G63. 4G64 ??

These work for a 4g64, 4g63, g4cs and I think even the newer Evo/Eclipse 2.0s and 2.4s but they're not for the timing belt. I didn think about it but I do have a particularly ugly timing belt tensioning tool I made, so ugly it won't be showin its mug here, I assure you!

These are 1 driver and 1 installer used in a bottom end performance mod on the above engines. Here's a hint after I did this mod I blew off the oil filter a week later, caught it right when it happened, popped on another filter and 3-1/2 qts of oil and went on my way. 1 wk later I had the same thing happen at about 6500 rpm passin on the highway and wasn't so lucky (headexplode)

What do I know.. I have a Pearl Yellow 1994 Mitsu 3000GT VR4 with only 5,700 miles on it. I hardly ever drive it let alone work on it. No mods either.

Ok, Ok .... they're drivers and installers for removing the balance shaft bearings and then installing new ones that are solid, meaning they lack an oil hole that's intended to lubricate the front and back balance shafts in their bores. The nuts are welded on 'em so you can use a socket and 1/2" extension to hold 'em so you can pound 'em outta their bores then the seat cut on the tool holds the new bearing on the driver so it can be driven in the bore to then block the oil ports in the block that feed the bearings.

This is done when you remove the front and back counter rotating balance shafts from the bottom end. At about 14lbs of reciprocating mass driven by the crank they consume hp for every revolution of the engine and their only real benefit is to dampen out a transient vibration in the bottom end that occurs between 3k and 3.5k rpm.

Removing the balance shalves removes their parasitic hp drain and then installing new bearings with the oil holes blocked off also gives a healthy increase in oil pressure too, which is what wound up blowin my oil filter off twice, with the second event havin taken out the crank and rod bearings and puttin the old Talon to rest for good.

With right at 200k on the clock, and about 135k of that under my heavy right foot beatin the hell out of it daily, and needin an engine rebuild with the complete suspension needin rebuilt too I scrapped the ol beast and snagged an Eclipse with about 1/2 that many miles on it thumbs

Oh...now I see. Sorry, never removed the balancer shafts from any of my Mitsubishis. The only thing I do remember about them was that it was a popular mod on the 1986-89 Chrysler Conquest and Mitsu Starion G54B 2.6L, although I felt that the smooth engine and pleasant whine the balance shafts made were desirable traits.

BTW, thanks Mrkim for posting these. It has been interesting to try and figure them out, even for somebody with limited workshop experience like me.
