    what purpose does the bar running from the transfer case to the engine block serve?
    i have one on the passenger side that is not bolted to the engine, it is however still attached to the transfer case. do i need this? it makes exhaust work a pain in the a$$ and it rattles occasionally against the exhaust. is there supposed to be one on the drivers side also? i'm also leaking transfer case oil where the bolts attach this rod.

    I would suppose that you're running a 208 also, its there to help support the aluminium transfer case, I've never seen one leak at a bolt hole however....put the bolts back in and when you need to work on the exhaust just remove it! might try some sealant on the treads to the t-case bolt! Later

    What case do you have?? It doesnt matter actually,.... its there to support the T-case. Yes I would say you should keep it. As far as the leak goes I have never seen that, the bolts dont go all the way into the case itself, they should have a "bottom" to them. At least on my 208 they dont go all the way thru. I have removed the support for work and never had it leak. And finally no, there is not one on the drivers side.

    it's a np203. and yes it leaks. i tried to take it off to do some exhaust work only to get a gear oil shower. it was arousing, yet hard to clean up.[​IMG]. as far as aluminum goes....i should be so lucky[​IMG]. my t-case about wore me out while installing the part-time conversion kit in the GRAVEL driveway!!!

    HUH! Aroused by a gear oil shower. LOL!! I would keep it personally. Just get a longer bolt for a bellhousing bolt, and put it back in. I would think it was put there for a reason. I am a believer in more is better when it comes to bracing. That and someone at GM got paid alot of money to figure out it needed it.

    Yes there is a support rod on Both sides of the Tcase back to the engine, at least on the 1983 208 there is, I would suspect that someone before you has put a bolt to long for the casing hole and cracked the inside of the casing off hence the leak at the hole, again sealant at the bolt should seal it off.
    Good Luck

    yes it's important. The 203 is a HEAVY PIG. those were added to help prevent the bell housing breaking or ripping the bolt out of the back of the tranny. They had a problem with that happening the first few years (including my 75). Also if your truck still has it's proper 4x4 TH350 that showed up 76 or 77 there should be a cast bell housing cover with 2 rods off the bottom going to plates at the motor mount to again help sprengthen the bell housing.
    There never was one on the driverside.
    Now I find it hard to believe you have a leak at those bolts. They should not be drilled through. My 75 never had the bar but it does have the holes and not drilled through. I have a bar that I'm adding but my exhaust is in the way. The lady's 79 has the rod but I have had it off several times and again the holes are not drilled through.

    i'm telling you the truth! since posting this i went out and pulled the bolts out at the transfer case and out came the oil....out of both bolt holes.
    there is only one support rod to the transfer case(passenger side) and one from the bell housing to the engine block on the drivers side.

    My 79 with an np203 has the same bar, but mine does not leak out of those bolt holes when the bar is removed. I'd agree with the post above on someone previously cracking the bottom of the bolt holes with too long of bolts.

    I started with nothing and I still have most of that left! - <a target="_blank" href=http://www.echobit.com:81/k5/> Pictures</a>

    My K5 is set up with a Turbo 400 and NP 205 from a 1980 1-ton. The t-case came with that brace, so I installed it. [​IMG]

    Knight you MAY be thinking of the supports from the eng mount area to the bottom of the bellhousing. (the flywheel cover.) There is supposed to be 2 there. My 86 w/ a 208 only has 1 brace to the T-case.

    Those bolts should not leak, much less pour out.

    Both my trucks have the support bar on the pass side and both have 208s. Neither one of them have oil comming out of them when I remove the bolts.

    Good answer Grim. I have a question for you or anyone else who may have added this bar. What modifications are you making (or planning to make) to add the support bar in? I wanted to do that to mine (75), but I haven't seen the improved strengthened version up close to get ideas from. Thanks

    No sir, there are TWO support rods that go the engine, and back to the t-case, has nothing to do with the bell housing, maybe they just elected to put the second one on mine for farts/and giggles? Or where physic and KNEW how much abuse I was going to give it?

    That's strange that yours are drilled through. Get yourself some teflon tape for the threads to seal it up. Also weird that you only have one of the rods off the bellhousing cover. Does it have the boss for the second rod? On my 79 there is a totale of 3 rods. one off the side of the transfer case to a bell housing bolt and the 2 off the bellhousing inspection cover to the motor mounts.

    yep! only two bars. the problem just got worse!!!!!
    the bolt that originally held the brace to the bellhousing has been broken off below the surface, i guess that explains the reason it was just hangin' there. the only way to tap the bolt and extract it is to drop the transmission.
    i've decided to move it to the bolt up above it, the one where the dipstick tube bolts. the problem with that is i'm going to have to have it extended about 1 inch. then there is the matter of exhaust work if the bar is again in the way.
