Removing intake manifold on stepdown

super-six

In the end, what's the easier way? Removing the inner fender or not? It's been too long and too many different cars ago. I can't recall how bad it is to remove the inner fender, but it looks like I can count on some scratched paint. Thanks.

I've found I can get to all the nuts on the bottom side just by feel. The exhaust pipe connection is easiest from underneath the car.

remove the inner fender. You can then do it sitting down. It also depends on how long the mannifold has been on and the trifocals of your glasses.lol

I agree with 1951 hornethardtop. As far as scratching the paint, you can minimize the risk by droppping the inner fender out the bottom. It also helps to remove the front wheel.

I finally decided to remove the inner fender and it was easier than I expected. Thanks to all for the replies. I had a bad vacuum leak that I couldn't locate and this is what I found:

I had a tough time getting the inner fender back on my 50 pacemaker. Everything I've read seems to disagree with my experience, are the swb cars much worse?

Super, Is that picture of the intake passage in your Twin H intake manifold and the rot out probably due to exhaust gas erosion?

Yes. There's more rot in the exhaust passages within the intake manifold.

Wow! How hard was that to troubleshoot?

I recently had both inner fender panels off my 51 Pacemaker, no problem what so ever. Needed to check valve adjustment, then continued to strip everything off the motor and firewall. Painted the firewall body color-- Had been black from before I bought it. Stripped and painted every thing under the hood. Lookin good now.

TwinH,

I checked all lines, vacuum advance, fuel pump, wiper motor, did compression test. Narrowed it down to gaskets or intake manifold. All gaskets looked good.

I wonder that if you cleaned up the visible holes and sealed them with something like J B Weld and then blocked off the heat riser passages by removing the heat riser valve and using a block-off plate that you could make the manifold reusable? You would have no carb heat and it might run a bit rough until things warmed up.
