I can not find the name of this and what its purpose is, all I know is it is all carboned up?

 

EGR pipe or EGR tube

Exhaust gas recirculation = EGR

It cools off cylinder "explosions" by mixing exhaust gases with incoming air so ignition in the cylinders is slower, so low temp, and less NOX(toxic) gases are produced
Also reduces pinging/knocking by keeping cylinders cooler

Computer controls the EGR Valve, which controls the amount of exhaust gases mixed in, based on the Load on the engine, higher load would normally cause higher NOX production
EGR system wouldn't be used at idle or lower RPMs or when engine is cold

 

Thanks, I was thinking it had something to do with that. I am old school from the good old days of carburated/mechanical timing with none of this crap that makes engines basically consume their crap. Slower ignition, that is blasphemy when talking about power

 

Not really, EGR allows for more aggressive spark timing, its actually more power if you run Regular gas at medium engine load, because no pinging/knocking
On high load, i.e. throttle wide open, the EGR system is not used, same as O2s are not used, to give maximum power at that time, but the Richer mix has its own cooling effect

At medium loads for best MPG and power, EGR is a benefit

People think the same about Cat Converters, they steal power, they don't, an old clogged Cat(or muffler) will, lol


The old carb/distributor systems without ANY emissions stuff, I grew up with them as well, were POS compared to the EFI/distrbutorless systems with emissions stuff

Emissions stuff added a layer of service work, but so did tri-power or dual points, PITA tuning, and have to tune at least once a month for a daily driver
People delete an EGR system because its easier and/or cheaper to do that than to repair it

I think the biggest problem with EFI/distrbutorless systems is that they are TOO RELIABLE, lol, you DO NOT have to work on them monthly so when there is a problem most don't know where to start looking

 

I hear you but I removed my cats, I built a straight pipe and it was amazing how much more power I had, the engine ran way better and has better gas mileage than when I bought it new. The EGR is placed in the most ridiculous place making it not even worth replacing on Ford Rangers. For me, it will get a blank plate installed on it and the intake will get a blank plate on it. and that pipe will be removed. For the PCV system, I made a plate for the crap oil separator/PCV valve and capped the intake where it hooked up. Did a little mode to the valve cover and nothing but an open PVC system now on this engine, it's crazy how much oil and carbon buildup happens on the Duratec engines it's just crazy and it does nothing more than kill the engine in the name of saving the earth but my gut tells me it is...
buy a new car from us.

 

I believe you, but as far as the Cats its not possible unless they were bad, no Ranger engine ever came with back-pressure in a stock exhaust system, in fact they all came with factory scavenging exhaust manifolds, develops lower pressure at mid-RPMs

As long as you didn't do the original "PCV" system then that's fine
Original crank case ventilation was a hole and tube on lower block or upper oil pan, just pointed down at the ground, and dripped oil constantly, as miles got higher and with it blow-by, more oil dripped out
Now that would get sucked into the intake with a current PCV system, but that's what catch-cans are for

EGR is a personal choice, unless you have to pass emissions tests
