Default new exhaust manifolds

Just thought I'd relate what happened to me a couple of weeks ago and what I learned.

I've always had an exhaust leak at the rear of my passenger side exhaust manifold.
For my Christmas present this year, I figured I could pay to get the gasket replaced. My luck being what it is, I knew I would probably break off all the bolts if I tried to do it...and I didn't want to ruin Christmas.

Anyway, the shop told me the bolts came out very easily. The only problem was that one of the tabs on the manifold was broken and literally fell apart when the bolt was removed. When the other manifold was removed and sanblasted, it too had many cracks around the bolt "tabs". Both of them were just junk.

Luckily, a local retired Ford mechanic had a set of almost NOS '61 Ford manifolds. The driver's side flange didn't meet up with the exhaust pipe exactly, but was close enough so that the pipe could be heated and twisted the 1/2 inch or so for it to align properly.

We also discovered that the exhaust valve mechanism was messed up and the pin and spring were malfunctioning - no wonder the car ran so bad when it was cold.

To wrap up this long story, the shop installed the new exhaust manifolds and rebuilt the exhaust valve.
Now, the car runs terrific - even when cold - and the "ticking" sound of the leaky gasket is no longer.

I never thought the exhaust valve could make so much of a difference in warming up the car or in how it runs, but it does.

Make sure yours is working properly!

Default RE: new exhaust manifolds

If you need a new exhust valve, they do reproduce them for about $90. I agree they make a tremendous diffrence in the cold weather. What also makes a diffrence is cleaning out the crossover passages in the intake manifold. The one in my 1960 was completely closed with carbon buildup. Warm-up is much better now.
