Hello all. I have a problem with the intake manifold heater hose connection on a '97 CVPI. There is a metal pipe with very fine threads that screws into the plastic pipe on the back corner of the manifold, also very fine threads. That plastic pipe/post is cracked, and the heater hose with nipple still attached blew out yesterday. I thought I could get by for a week or so with a hose clamp around the cracked pipe/post and reseal and rethread the metal nipple back in, until I can afford a manifold.
BUT...here's the weird part: the metal nipple is too small for the plastic! The crack has been tightened so it almost disappears, but there's a LOT of slop in the fit. The threads won't even think about engaging, even when the nipple is bottomed out in the pipe/post. I haven't measured the slop, but I would estimate at least 1/16".
I'm at a loss...did the former owner change something? Are all your manifold to nipple connections set up the same? Anyone run into this before? Could a major amount of RTV or Teflon tape hold the seal for a while (with or without pressure in the cooling system)? Does a new manifold come with the heater hose nipple already installed?
The intake manifold is all plastic, BTW.
Thanks in advance for your responses and HELP!!!!!
