what are peoples thoughts on heli coiling the hole or my uncle was telling me about some rubber insert with a new bolt thing. . . or just plain loctite.

You need to find a heli coil of the proper size and a new plug to fit.
(I seriuosly doubt the original size is available as a heli coil.. I have never seen one but that could be me )
And you need the proper tools to insert that heli coil too.

That fill bolt has a "build in" washer right?
(I don't know/remember the proper English term for that)
If you decide to use Loctite, apply it there, where you have the most surface.
And use the type that can withstand heat.
Some types of Loctite get soft with heat, allthough that is usually a lot hotter then a transmission I guess.

Succes.

 

You don't normally need a new plug. You drill the hole out to a larger size then tap it with the supplied tap, screw in the threaded insert with the supplied tool (everything but, the drill bit's in the Helicoil kit) then you screw the same plug back into the hole that was originally there.

The manual doesn't show the size or thread pitch.

The manual shows that the bolt has an integral washer but, there's also an aluminum washer that's used to seal the interface. My guess is you didn't strip this. I've forgotten the washer before and didn't hurt anything. The other option is a self tapping bolt that cut's it's own threads.

Personally, I wouldn't try to glue it which is basically what you're trying to do with the locktite it sounds like.

 

i can get it down to a little more than hand strength and i decided to go with some silcone rubber stopper (its called RTV and its blue) around the threads. this will hold for a or at least create some sort of seal until i can either have it retapped or a helicoil inserted into it. i wonder if there is enough room to insert a heli coil with the transmission still on the car. i wont be driving the car too much until i get this problem fixed. i really appreciate the feedback spitfireS and EK9

 

This stuff? I certainly wouldn't trust that even for an hour.

 

If it handtightens, can you drill a 1/16 into the edge and wire it to a nearby fin , ala race-prepping drain-plugs? That's splash lube in there; there can't be much pressure. I've had success in the past putting self-taps into steel oil pans, but am unsure about the AL case. Heli-coils take some skill. I've seen some motorcycle mechanics with some serious heli-coil skills, to include spark plugs in AL heads. Good luck, though.

 

yeah thats the exact stuff. . . its supposed to work decently well its just a temp fix though. it handtightens to a certain degree and if i spin it past a cerain point it begins to unthread and then rethreads again. im going to try to find one of these rubber cork thingies with a threaded hole in them that has a bolt which threads into that. the hole in the cork thing is smaller than the diameter of the bolt so the bolt actually expands the rubber into the existing or in my case remaining threads of the fill hole. this should last me until i figure out how/ when i helicoil it. im not overly concerned i just miss driving my baby. plus i feel like an arse stripping the thread. which i have to verify wasnt entirely my fault

 

Eh...just plug it with your thumb and cut it off...you have another anyway.

 

I have had that attitude my whole life, very impatient. It has bitten me in the rear more than once.

Do it right, just think what kind of hole you will be in if you are driving and that damn bolt comes out with all of your tranny oil.

If you wait a couple days and not drive it but fix it corectly, in one week you will not even remember the two days that you could not drive your car. just my .002

 

wrap teflon tape around the bolt. That will allow a tighter fit.
