exhaust work
« on: April 12, 2014, 03:14:49 PM »
Does anything need to be changed on the exhaust system when switching to the ranger manifold? 
 The front flange on my cat rusted off. My exhaust behind the cat is almost new.  It would be pretty easy to weld in a piece of pipe where the cat was.  But I'm wanting to get a ranger header as soon as possible.  Will the stock down-pipe bolt to the ranger maniofld?  I don't want to put any money into my exhaust just to have to modify it as soon as I find a ranger manifold.

thanks art, does it look like the ranger header dumps out at the same location and angle?

No, it dumps out at the back but if you shorten the pipe it will line up, Fred Morgan showed me his and it was hooked up to his original system, he said it was a piece of cake to do it.

I got my  manifold! 
How are you going to do your egr port?  I was hoping it was a female thread and I'd be able to put a plug in it. Do they make a cap that will thread on it?  Or should I just make a plug and weld it in ?

Good way to crack it if cast iron. Any way you can drill/tap for a slightly larger common plug?

I'm cutting that tube about 1/2" from the header, heating the nub & pinching it closed then welding the seam. Should be 10 minutes work.

If working right it does not. It is off at anything approaching full throttle and off at idle. It only works during cruise when you don't WANT power.

egr makes your intake dirty, show me clean exhaust pipe, the by products that come out of your exhaust eat up your valves and seals, it makes your engine run so much cleaner, i understand its to get the left overs and burn it, but at the cost of wear? and the pcv vent, scavenge that off into your exhaust, the fumes that come from that can gunk an egines intake, engines are living organisms, they need clean air too, sorry, its a pet peev

Friend of mine long time ago took all that junk off of his dually and put a Vac-U-Pan system on it, cleaned everything up and never had any leaks and got 3 more miles to the gal.. :D

I made a "cap" for the EGR fitting on the manifold.  I could have welded it shut, but this way if I ever switch to efi, I've got a  fairly easy place to put an O2 sensor.
I took an original EGR elbow. cut the male threaded section off, then tapped the hole that was left and threaded a bolt into it. Then cut the bolt of flush .

On a Ranger header, you can saw the threads off and then tap the hole metric for the O2 sencor. (I THINK)(HAVEN"T TRYED IT YET)
Its better to be a has-been, than a never was.

Depends on the sensor size I guess?, but yeah you could whack the threads off and tap it, you got over a half inch.

The sensor is a 18 X 1.5 MM with a .649 dia hole for tapping. And you can buy an extension for the O 2 sensor that could be welded to the header it taping was not possible.

Cheap non-foulers for spark plugs make a good bung once you mod them a bit. The big one for big 18 mm. plug as he says.
