port divider question?????????????????????

[strat1960s]

Well, I am in my garage changing out yet another header gasket and I found out what was making all the rattling noises in my motor. The welds that held my port divider in place broke loose. Now here is the deal; the port divider won't come out, I already tried, the other thing is that the rattling sound seens to go away after the motor has warmed up some.
What should I do? I don't have access to a welder or JB Weld.

Not trying to be sarcastic...I would go to the nearest pasrt store and buy some JB weld or equivalent and set it in place.
Sounds like it heats up and expands when hot which stops the rattle sound.

Good luck.

Look for some exhaust repair putty at the auto parts store. It is rated much higher on temp. then JB Weld. I used it to install my divider and it worked great. Total cost for putty was under five dollars.

Good Luck,

Hey, the same thing happened with me. What I chose to do was pull my cylinder head off and bring it to a machine ship. They heated the head uniformly, then tacked the port divider into place and machined the exhaust header mating surface flat to remove excess weld material. While it's a little bit of work and expense,

a) you know you're getting it fixed RIGHT--mine hasn't come loose and it was installed 4 years ago
b) it gives you the perfect opportunity to replace the lifters and pushrods--I pulled mine and discovered a sticking lifter and quite a few bent pushrods

Your call, but I recommend pulling the head and having the work done by a competent machinist. I think it cost me about $50 to get it done, and it was worth every penny to me--I had already pulled my headers twice to fix the problem with JBWeld.

JB burns. Tried it myself and it dries out and gets brittle and cracks apart into little chunks and bits. What I used was a brass epoxy. Rated at 750 degree continuous. It's a type of epoxy with 60% brass powder made for small boiler repairs and patches. Comes in a can with a brush. It's real thick and clings to almost anything. Including hands and clothes. There is a cheaper aluminum epoxy that is rated at 600 degree but still costs 45 bucks a can. It's machinable and drillable. You can run taps into it. I tried and it worked. I'll get the name of it asap if your interested in checking it out.
