I went to autozone, and they found one; but only after telling me 6 times that they didn't have anything like that it's a heater hose for a ford something. Just make them go look for prebent hose that's pretty close to the same diameter it may be a little bigger than stock but still seals up fine.



Also it has to be cut on both ends to make it fit perfect.

Didn't the tb mod eliminate the fast idle? Also, are you refering to the BAC when you say it'll get enough heat? Does the BAC really need coolant? [/quote]

bac doesn't need heat does it??? He was talking about the fast idle cam, it has thermowax that melts as the coolant heats up, turning off the fast idle cam. I mean the bac doesn't have anything like that, it just runs though a pipe on the outside of it... hmm.......

I went to ACE hardware and bought 2 hose connectors, threaded on one end and ribbed on the other, and a 90 degree elbow, everything brass...if this doesn't work, I'll go ahead and cap it, but I'd like to know what to do about the BAC...any takers?

well i can think of 2 things. 1. the bac valve had coolant in it from the factory, if they could have saved the $1 worth of hose and clamps then they would have. they dont have the coolant in the bac on the later cars and it works better.....

i'd keep the bacv, but eliminate the coolant. just plug the nipple on the rear of the engine and the water pump housing and be done with it. You can remove the small piece on the bacv which has the coolant flowing through it, it's just two screws holding it on.

I just took the line from the front and looped it to the rear so there'd be some coolant flow in those areas instead of none.

I tapped and plug the holes on the engine and the TB, after doing the TB mod, i just put my bac back on too https://www.nopistons.com/forums/pub...IR#>/happy.png

cool...now, I might sound stupid here, but that's never stopped me before: are these caps something I can get at any auto parts store? How tight does it have to be (pressurized system, right?)?



The brass fittings were going to work with some old hose cut to fit, but I think the more that I eliminate, the easier things will be.

um it has to hold about 15-20psi, not a lot.

After I do the TB mod to mine to my engine I'm garbaging that BACV.No need for it after that.Just makes it easier to work on and one less thing that could go wrong.Look at how many rotaries never had it?Theres a reason for that. https://www.nopistons.com/forums/pub...#>/biggrin.png
