since im posting iv got an oil pan leak can i do a qwick fix and put liquad gasket around the seal or would it be to hard to clean the oil off for it to stick
anyone have any ideas im gettin another motor in a few weeks so i just want a qwick fix

and another refering to welding a diff i know nothing of the sort but have a cousin inlaw that has a welder and as welded other diffs he wanted to know if the 3rd member comes out my expression was
is it easey to do,easey to remove from the axel or do i have to remove the axel then take it out??,easey to muck up as its my only diff? its a tempory till i get a lsd and i dont want 1 wheel spinin
i went to the woodburn drags and i am joining nxt weekend my cars bone stock etc but it looks so fun and i seen some slow cars i could race and have a chance
and i want to see what ill get before i start doin the usall upgrades
any pics,information,threads in your favourites postem up

THE END

 

ok iv done further searching and found this pic is this a good reference for some one thats welded a diff before im assuming its a 12a diff but not sure as this guy has a 13bt


my major q is can i remove it without takin the rear axel out ild like to do it in a day

 

it is a 12a diff

 

you got to pull the axles to pull out the dif

 

thanks

 

Tach works off the trailing. If the wires in the bay are good, you may need to pull the cluster and check behind it. There is a single wire with a bullet connector coming off the dizzy, make sure that connection is clean and solid, then trace the wire to the fire wall for any breaks or abrasions.

 

will do tomorro thanks for your input
what actually is the little bullet thig?

 

the little Bullet Thing..is just a One Wire connector,that looks like "a bullet" for the Male end of the connector..goes into the other half of the single wire Connector(female)...An example..the sensor on the bottom of the Rad on an S4..the pins on it ..YOU can use Female type bullet connectors if you break the Wires to the sensor.(overdone,but I think you should get the Picture)

 

well it awnsered half sorry i didnt wright out clear enough what i was refering to
the wire that the bullet connectors on what is this attached to i know where it is and what it looks like but what is it for what does it do

 

I believe the wire he's referring to is the signal for the Tach. If it's not making a good connection, it might explain your tach jumping around like that.

 

well what i think trochoid's refering to is theres a lil capcitor type thing and the right side which has a wire and a bullet like connector but i dont see how this gives signal as it only has 1 connection and screws to the side of the dizzy

 

I'm going to go look at mine, BRB.

 

get your direct fire mod to work

 

did you setup the direct fire mod yet

 

Well, I went to look and found what you're referring to. Mine is disconnected, along with vacuum advance, and my tach works fine. It was getting jumpy in high RPM, but it was missing up top. Adjusted the timing and it's perfect now

BTW, I still have the stock ignition setup, not Direct Fire yet.

 

im on stock again still peicing togetger for the j109 direct fire

im gonna pull the cluster out in the afternoon and see

 

well i think the tach is kaput

soo tell me whats the best kinda tach i sould get and where did you mount yours was it easey to wire etc? any pics of one mounted would be apreciated

 

that capacitor is the condenser it keeps you from hearing engine noise through your stereo (electrical feedback). It's not a necessary part but it does a job. I finished my direct fire wanna see it? It's gonna be a minute dial up sucks.

 

direct fire.

 

man, my pics are always the worst.

 

smallest iv ever seen hehee
so was much improvement from the upgrade

 

well im just postin a pic of my new tach installed ill improve it later but for now its positioned where i like it and hope others like it aswell
i didnt go for the big tach with shift light because that just looks out of place and really aint nessecary
maybe took 30min-50min to install but wasnt hard and very easey to wire

enjoy

one question does it matter witch coil i hook the signal up to?
i tryed both neg and both worked the same

yay i can see my revs now

 

I would have sourced a stock tach, I'm not a fan of aftermarket tachs and you loose the buzzer. If you change your mind, I do believe I have an 83 tach. If you keep it, hook it up to the trailing coil, that way you will know if the trailing side of the ignition goes out.

 

ok well im havin a lil problem somtimes this tach decideds to stop and when i floor it itl go back to zero im positive its wired right
could it maybe not gettin enough power? through the stock harness
or maybe somthin interfering with the signal wire
i swaped amother dizzy in think the weights on the other were jammed but not chage if i rev slowly the tach wil do its job fine

 

has anybody rewired there ignition wires? meaning the coil wires,igniter wires and anything that goes with it

i may have a short or broken wire this is thonly thing that could be causing this pita problem
