I have a 1999 f-150 2wd w/4.2. On the front of the intake manifold there is a metal tube molded/pressed into intake. This tube has a hole in it and is leaking. Is there a fix for this or does entire manifold need to be replaced? I used JB weld on it and it worked for a while but then it softened and started to leak again. Any help would be appreciated. Thanks
this happend alot in the 1997-1999 4.2l's after about 100k the manifold would leak into the top end...i think i heard that ford had a callback on that but im not sure, but the best thing to do in this case is to replace the manifold...
I found a replacement Ford OE part.. # F75Z-8555-AB. This is the exact part to the one that continually rusts out.
First I cut off the old tubeflush. then I took a small ( and I mean small ) hacksaw and cut throught the remaining piece that is still in the manifold. I then could get the piece out. I then coated the new piece with gasket shellac and made a homemade driver out of 1/2" pipe by cutting one side off. I used it to drive the new pipe home. Works great and no leaks.
