    No man just changed the bell housing, buy a core and switch over the insides. Youre going to spend the same.

    If youre car is awd and you have alot of mods, I would change it, because the integrity is already broken. and with all that force that is going on in there i wouldnt want to risk anything else happening. but i guess you could weld it if you wanted to. And mainly its free.

    Chances are that it would be ok. But, to be on the safe side, you might want to have it welded.

    to make the long story short... blew up a motor, put on new head, and another block i had in my car... all ran fine for 3 days. Heres what happend:

    on the 3rd day, the clutch started to feel like jello. So we thought it was the slave cyl, replaced it... still not working. but at the same time, there was this horrible squeeling noise, figured it was the throw out bearing. Went to replace that and realized the bell housing was cracked under the top hole on the intake side of the tranny, towards the exhaust side. Also the top hole on the exhaust side is completely broken off, on the bottom of the block on the exhaust side the ear is broken off.

    Now when it was taken apart, there are not marks on the flywheel, pressure plate, disc or input shaft.

    The one odd thing is that the line up pins that are in the block are now stuck in the tranny.


    What would have caused this to happen? Any ideas are greatly GREATLY appreciated. Just a little background in case anyone needs to know, ACT 2100, RRE Lightened flywheel, and a new transmission. And i hope this makes sense... as to i am about to go insane....:mad:

    Clutch housing bolts hadn't been torqued and worked loose.

    Hey I have a 92 AWD 5-speed trans sitting around over here with a cracked bell housing (the part that bolts to the engine block) and with some huge chunks broken off it. I was wondering what year trans I could pull off another bell housing and bolt it up?? Any info would be nice. Thanks.

    You should be able to use one off any 1G trans as long as they are the same IE FWD AWD. The only difference that i can for sure say is the 90 have different levers and spline count.

    Ok,

    heres the problem

    Recently the bolts connecting the bell housing to the block came loose..Making it hard to put into gear and it was grinding into the gears. I tigtened them up and all was fine..until yesterday, when I realized this was happening again. I looked uder the hood and car and all the bolt were tight. Then I realized that by the bolt that is closest to the bottom motor mount, the block was cracked right after the bolt and that the bell housing was shifting because of that everytime I pushed in the clutch. So a mechanic thinks that it can be welded, I need to know if this is possible. He is talking about welding the crack and then welding a plate to the motor mount w/ a 90 degree angle to the bolt and thread the bolt through the holein the plate and back into the block. This may be hard to understaand. I would like to know any input..

    Allright, ever since i put in my ACT 2600 my gears would grind like crazy and never go into gear. I snooped around and realized that 2 bolts were extremely loose from my bell housing to my block I tightened them up and the problem was resolved. But it keeps on coming back. there always coming loose, bolts arent stripped or anything just like they unthread themselves. Im think there is alot of flex between the B.H. and block that is causing this. also my pedal feels real sloppy no pressure. any one have a clue? :confused:
    Thanks,

    its possible that there streched. try getting some new bolts, and see if that helps. also are your torqueing those monsters???? ALSO are you sure you got all the bolts in on the bottom???????

    Also, use some lock-tite on the threads.
    Have you recently had the timing belt replaced? It sounds like you might be getting some vibration that may be causing your bolts loosening. I had a problem on a car I picked up and the rear balance shaft was 180 off and causing vibrations that the seller though was bad bearings. Its bolts were coming loose in the bellhousing from that. :rolleyes:

    I use lock tight every time and I torque them down to specifications and i just had my timing belt done 10,000 miles ago. Still dont know why, I'm gonna go out and do a lot of steps to it. Check the slave cylinder, master cylander, mess with the pedal assembly, adjust the something rod. hopefully i figure this out soon can drive it any where.LOL
    thanks alot guys,

    Well for future reference, you should get new bolts and use Locktite.
