Thinking out loud.

I could replace the midplate, but if you look closely at the case, you'll see the counter-shaft bore is oblong - which means a new case too. Believe it or not, these are very popular and parts are available, new, for them... including upgrades.

I'm pretty sure my Right Stuff tempenant (or permanary?) fix will hold until winter but the writing is on the wall... so what to chose - so far these seem to be the choices.

1) Doug Nash 5 speed ($3600)
2) New Super t-10 with upgrades ($2500)
3) fix and pray ($1000)
4) TKX at $3500
5) T56 - $2500 (found one for that with all the upgrades)

1) - complaints about clunky and a pain when cold - not just that but supply is questionable... that said, probably the least expensive option that will handle what I dish out.
2) - highest rating I've found is 325 ft lbs -though rumor is they can handle more....
3) cheapest - and it leaves me with a spare or sellable trans
4) they can't seem to come up with a price, but I think if I do this one, I'll spend the 'extra' and get the one rated to 900 ft. lbs (stock is 600)
5) requires replacement of my bellhousing so could be the most expensive (and could require hydraulic clutch change)..Could also be the cheapest, but it never works that way for me....

the tl;dr is I think the mid-plate is cracked... but I'm going to run it
so
they say you should pull the main shaft out to pull the midplate....
no, you don't


the came a gasket search. I'm not convinced the rebuilder made a mistake - granted, the gasket he used was leaking - but still, there's probably a crack here somewhere


more gasket fun



somewhere on here

see the dirty blank spaces? those were both sealed and clean 300 miles ago

then there was the moment Luigi was laying at my feet while I dropped a gasket sealant brush on him.... oops

replaced the bushings while I was at it



back in and leaking.... we won't talk about how it's sealed now

in other news, I can now use my laptop to program the Sniper


and in still other news

trans oil leak. Yeah, I get it, I can always just add lube AND the level will never get to critical... but still.

driveshaft out

new seal kit

trans out

bright side is there is no oil on the inside of the bellhousing

it might be that just the tail housing gasket was leaking, and yes, it's a lot more work to do it right


so sue me. The other side of that story is the counter-shaft may be loosening in its bore. Now, I can 'just' replace the case. Let it go long enough and it'll destroy everything

port isn't round - but I think I found the issue.... the header bolts were too long

yes dear-- i know the heads exhaust port aint round. but the PIPE (header tube) is......
long header bolts will do it too--but if it persists, try a round port gasket. its worked
great for me for decades.

this post makes little sense without another post done elsewhere

In wheel searching... I came across this at https://support.apexraceparts.com/hc...ment-Guide#htr

not sure I can stuff a 315 under the front but maybe a 295?

Another thing, I need to find some C7 flares.... maybe that would be the best way to get the tire/wheel I want under the car....
Currently, I think I'm -1.5 degrees front and maybe -1.0 rear.... now I've got to check


Okay quote and what is right now.
-1.1 F camber
-.9 rear

.30* TO (or 1/8" TO)

I was asked to measure steering angle.

all at 25*
3/4" TO
3.6 degrees (I think)
-1.75 camber inside
-1.375 camber outside

I sound 'smart' but the terms come from this article

you need round port exhaust gaskets. the 'corners' on the ones you have are where its leaking.
i have much better luck with round port to match pip[e side. put a round gasket on head and a
square gasket on pipe, and youll see why i do this. i also make sure if its a 2" pipe, i have a 2"
round port gasket not a 2-1/8" or 2-1/4"....

back to exhaust gaskets

and replaced


and back to 400# springs in the front

and done

[SuperBuickGuy]

shop full of C3s

time to fix an exhaust leak

guaranteed.... just like the last one


also did some fixes on the cooling system.
about the trans
it was overfull


which could be the leak... I'll know tomorrow...

PS C3
it's getting a rear suspension... the old one was VERY worn out... so it's getting a full upgrade



then a motor.... then a front coil-over...

We need a "Bummer Dude" button alongside the "Like" button. But good you found the leak and hopefully a little tightening will fix it.

Damm,
You are having more "T-Minus Launch Delays" than Boeing's Starliner.......

[Deaf Bob]

no
if you look closely, you'll see the gasket squeezing out between the tail housing and the main body.... bolts were loose

Dang.
locktite?

[SuperBuickGuy]

Where’s the leak from? Speedo hookup?

So. Track night in America.

f**k Washington, its traffic and the idiots who think choo choo trains solve anything.

Nothing is so annoying as reserving 3 hours to drive 1 1/2 hours then realizing at hour 3 that you're not half way there.

HOWEVER.

I got home, unloaded my car and saw a huge oil slick where the trans continues to leak. Probably would have blown it up at the track - so I guess I dodged a bullet, but still annoyed that I missed yet another opportunity to race.
