Default Broken lower TCT bolt

As the topic states I noticed one of the bolts on my tct was loose and I had a very minor oil leak from there. I know it's from there because I cleaned the engine after I replaced the valve cover gasket and a few hours later I had a small film of oil under the TCT. Anyway, anybody have any pointers how I can extract that bolt? It's the lowest bolt closest to the exhaust manifold. Thanks in advance.

It won't have much pressure on it once the top part of the bolt is broken, it sounds like someone over-tightened the bolt. If you don't have one already, get yourself a bolt extraction set and it should come out without much fuss. They are pretty cheap to buy.

Weld a dag off the broken off stub and grab it with some side cutters and twist.

I would but the broken off part is recessed inside the threads. This is the service port of the tct and not the actual tct itself. Could I just unbolt one of the service port bolts and just spin the part until it clears the bolt stub? Also the bolt is tiny so I don't know where I could get such a small extractor.

So it is the cover, NOT the bolts mounting to the block, correct? The two bolts holding the small plate on? [img]http://www.inlinepro.com/s1/images/PRODUCT/medium/158.jpg[img]

If so, yes you can unbolt the other bolt to get the broken out. Might want to replace the little gasket in there as well. Do NOT loosen the bolts that hold the tensioner to the block and re-tighten. This could cause damage if the tensioner is not reinstalled properly.

Yes correct the brass ones that hold the tct in place are fine. I tried taking out the other bolt and I couldn't move the plate, all it did was drip a drop or two of oil. I just bought a small manual extractor, I'm going to see if I can pull the bolt out with this when I get home. If I can't do it, I'll just buy a new TCT and seal this one. I mean I don't know if enough oil pressure can build up in the cover to push out the broken bolt, or if oil is just going to seep out. BTW does anyone have the dimensions of that bolt in case I can extract it?

The plate will come off its just stuck. Wrap a cloth on it and use some pliers.

You can take the good bolt to Lowe's or any hardware store and get a replacement.

Ok update time! I got home, I used the extractor but I just ended up driving the broken bolt into the threads. I unbolted the other bolt, and pulled off the plate, then with needle nose pliers I grabbed the little bit of bolt that was sticking out of the body of the tct, carefully I unscrewed it and voila problem solved. I ordered two new bolts and a new gasket for the plate from Honda. I also removed the old gasket and I cut up a box of Golden Grams into the shape of the gasket and placed it where the slot for the gasket goes, I placed the old gasket over it. I cleaned all the mating surfaces with rubbing alcohol and bolted the plate with the one good bolt and one I picked up at the hardware store and torqued to 8 ft/lbs. I drove the car for a little bit and so far no more leaks, now I'm just waiting for the parts to come in and I'll change them to the OEM ones.

Thanks everyone for all your help, these forums and a good set of hand tools and you can pretty much fix anything with these cars.

Dude...Honey Grahms would have worked better. But I did use Triscuts once.
