BE Exhaust manifold surgery....

[198686d]

Thanks to the help of so many of you, I'm progressively increasing the complexity of services on the BE I never would have attempted before joining the Forum.

Now for the next: In very simple descriptive language (as if you were explaining it to an average 7th grader), how do I remove the exhast manifold. Going to have it sandblasted and finished in black or chrome or ? I will take photos, but unless I know what I'm doing they will be photos of train wreck.

Remove the 5 nuts where it is attached to the head. Remove the coupling where it is attached to the exhaust pipe.

Jack: Sounds straight-forward and simple...like all thing BE, however, I'll bet there's more to it than one first expects.

I'll get on it.

Hehe, I bet that's it, carbs will come loose but that's fine.

Jack you are evil :wink:

 

[jlaird]

Evil? Me? Naaaa, this is not rocket science guys.

When you get the nuts to the head off, remove the fuel input line to the carbs and just tie the carbs and intake to the fender so it is out of the way. Heck, you will not even need to adjust the carbs when you put em back and the only disconnect is the fuel line. Throtle and choke will be good to go.

Now you can get to the exhaust connection to the tail pipe easly for removal and reinstall. I always have a prob getting that joint to seal so I use a bit of muffler paste on my finger to wipe around the connection before I mate them.

black or chrome or ?

You are talking about a powder/ceramic coating, right? Chrome and high temp paint doesn't stay nice for long. Of course, with black paint you can touch up, but its a pain.
Google "ceramic exhaust coating" to see what I'm refering to.

Checked with Mr. Powder Coat here in St. Louie.....he says you can't powder coat anything that will get hotter than 400 degrees. And, right, now I know I can't chrome. So what is the best thing to do after sandblasting exhaust manifold?

thanks,

Ceramic, otherwise forget it, it came from the factory rusty.

May be that HE doesn't coat anything that will get hot, but there's a whole industry that does just that. I went with JetHot...kinda pricey, but a great job.

If you'll pardon a dumb question, what's wrong with high-temperature paint? I've never done this before, and I might sometime soon, so that's a genuine question.

It is not as durable as the ceramic materials. When you put it on an experienced rusty manifold the rust will eventually come back. If your into low cost and you're willing to redo the paint every couple of years (or put up with some rust) there is nothing wrong with high temp paint.

The ceramic coaters claim their product reduces underhood temps by keeping more heat in the manifold or header.

O.K. So there just a bit more to it than removing a few bolts.

Put it still sounds doable for my low level of ability.

 

[198686d]

ceramic exhast coating sounds like the real ticket. I'm checking out places near here that do it. Any idea of approximate cost?

that looks great

JetHot did the header pictured above for $183 (includes shipping).

No idea on costs, but you can get a free estimate

Cost for headers for my big healey was $225.

Exhaust temps coming out of the exhaust ports is over 1000 degrees, so the exhaust paints on the shelf at your local parts store, will quickly come off the headers or exhaust manifold, say a good 6-12 inches down form the head, form the collector or exhaust back they work OK, as the temp quickly drop as they go thru the exhaust. The cerramic coatings will withstand this sort of temps, but over time they will too disapate, well atleast on racer headers they do, probably last a lot longer on street cars. Jethot is a nice, tough finish, if it's in the budget, go for it.

 

[198686d]

That is a lot. But, it's still an option.

thanks,
