Hello freinds,

does anybody know how to pull the rivets which hold the little pan under the stock Intake?
Is it a good idea to head up the area arround thr rivet with an flame?

I want to clean my spare intake and the accociated Heads which belongs to a '69 460 cid.

Thank you for your help

Years ago, I was about to center-punch the rivets and drill them out. Then I wondered how I would attach the pan again. I thought of tapping the holes, and using screws with some thread locker on them.

But after looking at it more, in my case, I decided to try to poke out and use a lot of solvent to remove all of the coked oil that was between the pan and the underside of the intake. I kept working at it and got it cleaned out pretty good.

I assume the purpose of the pan was to try to keep oil off of the hot underside of the exhaust cross-over passage in the intake.

As far as torching around the rivets, I wonder if that would be abusing cast-iron, would not want it to crack, or distort the shape of the manifold, or else it won't seal well to the cylinder heads, and end up with coolant leaks there. Those are my thoughts, anyway.

 

Hello Torky2,

thank you for your response.
I am with you, the the purpose of the pan was to keep the hot oil off the hot underside of the cross-over passage, but I wonder why there ist not one or two drain holes to let the oil -which maybe reaches the inside of the pan -flows back into the engine before it will coking...

I also think that torching is not the best Idea as you wrote.
So the best way is to clean the manifold with lots of cleaning solvent (PF145)

Thank you very much and sorry for my english, it's not working perfekt at present day

Hello,

Please forget what I wrote regarding the drain holes. I just found out that there are two drainholes, but in my case completely leakproof. I thought that was just a stamping in the pan.


thanks

have a nice week
