motoman Posted July 5, 2010 Share Posted July 5, 2010 (edited) I have a freddy intake for my rb25det however the part for the coolant comes off shown in the picture.Is there anyway i can get that to stay where it needs to be? I know i cant weld it because the IM is cast. Edited July 5, 2010 by motoman Quote Link to comment Share on other sites More sharing options...
mrflip69 Posted July 5, 2010 Share Posted July 5, 2010 You can weld it, that's what was done with mine; no leaks no problems. JB Weld or proper. You can replace the pipe with a proper fitting piece. Quote Link to comment Share on other sites More sharing options...
jc052685 Posted July 5, 2010 Share Posted July 5, 2010 You can weld cast aluminum. Quote Link to comment Share on other sites More sharing options...
motoman Posted July 5, 2010 Author Share Posted July 5, 2010 So i can weld cast. I guess you learn something new everyday. Quote Link to comment Share on other sites More sharing options...
RS Speed Posted July 6, 2010 Share Posted July 6, 2010 I've installed a bunch of these manifolds. I've always used gobs of silicone. Insert and leave it alone for a day to harden.... never had a leak. Quote Link to comment Share on other sites More sharing options...
90TSIAWD Posted July 7, 2010 Share Posted July 7, 2010 I just used JB weld on mine and wiped it with a wet finger (think caulking) to make it look decent. Works fine. Quote Link to comment Share on other sites More sharing options...
5thgenluder Posted July 10, 2010 Share Posted July 10, 2010 rather than start a new thread I thought Id just add on to this one. I am piecing together my rb swap and am curious. Whats the deal with all these knockoff Greddy intakes? Are any of them consistent or good? I was looking at this one. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=380248322210&ssPageName=STRK:MEWAX:IT Is it worth it to just save and buy the Greddy or are these knockoffs decent? I guess the return policy and feedback policy at the bottom of the page just give me a weird vibe. Maybe Im crazy. Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted July 11, 2010 Share Posted July 11, 2010 I have your solution. Mine did the same thing. Permatex makes a special type of bonding agent for this situation. Here is a link to my thread that explains it better. I tested mine a day or so after I did it. I grabbed it and tried to twist about as hard as I could and it did not move. You will need a torch to heat it up to get it off later. http://www.240sxforums.com/forums/rb-parts-f-s/130859-ebay-rb25det-intake-manifold-causing-problems-coolant-pipe-doesnt-fit.html Quote Link to comment Share on other sites More sharing options...

My personal experience and observation of others is that they do not sell cast manifolds. Only polished. If you order cast, they will send you polished. If you complain, they will say "our mistake" and offer a refund. That is, if you bother to ship it back and lose money on it. My theory is that they cannot cast a part well enough to leave it 'as cast' so they polish them to remove most of the blemishes. If you buy one, there will be a few flaws, but typically nothing your average HZ'er cannot handle. Quote Link to comment Share on other sites More sharing options...
motoman Posted July 11, 2010 Author Share Posted July 11, 2010 (edited) 5thgenluder: To be honest i would say the the one i got is a very good casting. There is minor flaws in it and its not polished like Wizardblack is saying. WizardBlack: What is the name of the stuff you were talking about i'm not on the 240 fourms.

5thgenluder Posted July 11, 2010 Share Posted July 11, 2010 I think I'm gonna go with the knockoff. If it real bad I'll swap it next year when I upgrade the motor. Quote Link to comment Share on other sites More sharing options...
