Vlave covers and TB

mustangspartan · Oct 31, 2011

Ok guys i bought the trick flow heads with a whole plan of attack in my head of reusing my 1.7 cobra RR and valve covers

Jumped the gun a little to fast.. So i got the stud mount 1.72 Scorpion RR and also a 1/2 spacer for the cobra upper to lower. Im also running the BBk 70mm throttle body. Now from what im understanding to clear it all im going to have to run the foxbody valve covers and at least a 3/8 inch spacer.

Looking at these and then buying the breather hole. Then the 1/2 spacer should be good. Idk if anyone has done this before or is running a something like this for a setup. I see a decent amount buying the foxbody TB adaptor but looking at it i shouldnt need it..

Any input on this would be great..
Sorry search engine was not working for me..

I dont think you need a spacer with the fox valve covers.

I don't know if those valve covers will clear the RRs, they kind of look like the stamped sheet metal ones that come on the 94-95s. Also remember that if you're going to use an intake spacer you'll probably need to extend the EGR tube. Depending on what covers you get you might not need a spacer

Egr is going bye bye and the reason im looking at these one is they have the same hieght as the foxbody cover at 3.5 inch. Hard to find also fox covers in my area

There's lot of other 5.0s that have the same valve covers. Lincolns. Mercurys. Etc.

Deleting the EGR is dumb.

Deleting egr gives you 1000hp and 40mpg.

There is no real benefit to EGR delete besides not having it there.

That was enough for me to delete it though lol

OK i know taking out the egr is one thing and this will go back and forth and back and forth and wait back and forth again right on this topic. Its the same as when people talk about cats. I think they both work for what you want and also on a vehicle that is mostly stock. I do not like that with the amount of ethanol that MN is now having standard unless you run non oxy gas (which i do) gums up the system. Taking my stuff apart just after 90k and seeing how much crap is everwhere and how gummy my system is, is more then enough for me to not believe in a control system to help you from cold start damage and reburn a little spent gas that wasnt 100% used. But each there own and blah blah blah.
(yes i do know that at wide open throttle it turns off)
Also a ton of room is now available for me to install long tubes..
So nobody has tried these im guessing...

Paul · Nov 2, 2011

It has nothing to do with cold start damage or re-burning spent gas.

g36 monkey · Nov 2, 2011

it cycles unburned fuel back into the intake. its not used under a load. you don't lose or gain performance from it.

It's to meet state regulations for environment.

If you don't have an inspection, I would wait for it to break then delete it. I wish I wouldn't have spent the money years ago to fix it because I thought deleting it would be too much of an undertaking. Now I know how easy it is, and havent looked back.

The Egr will dilute the incoming air/fuel mixture that will make a quenching effect on combustion temperatures which help with NOX. A benefit of this is it reduces the engine's octane requirements which in turn lowers the danger of detonation (spark knock). All egr systems will cause carbon build up it depends on gas used and also driving habbits for how fast this will be achieved. The pump puts air into the heads when the engine is cold and then into the catalytic converters when it is warm. The Thermactor control valves serve to direct the flow. This is all the included if you do a delete kit. 1. getting rid of the pump 2. getting rid of all the EGR system. By deleting the system im actually gaining two things. 1.more room 2. a pump causing some drain on the system.

Sorry the EGR alone is for Cold start diesel engines. PFE and DPFE systems are all used in 96 and newer fords. Correct me if im wrong but the 5.0 uses a Backpressure system.
On a back pressure system really any modifications done to the exhaust will now make it worthless. Too much flow for what it is designed for unless you want to upgrade or modify the EGR.

That is all im going to say about this and again going back to the original ? anyone run these covers before??

Paul · Nov 3, 2011

Looks like Google helped you out.

Still, there is no advantage to removing it. EGR increases fuel mileage, reduces detonation, and removing throws a CEL and can cause drivability issues. Plus, it makes the car run cleaner! I'm no environmentalist, but it is a benefit to some.

In my sticky thread in this forum, I showed that fox valve covers fit over aluminum roller rockers and I had no spacer between the upper/lower intake. Unfortunately, those pictures went down with the old host. I can try to get them re-hosted for you.

I went tru hell trying to get egr to work on my car.

mustangspartan · Nov 6, 2011

Sorry but google is not as cool as my mobile equipment technician degree. its a nice tool to use here and there for reference but thats about it..
Ok cool beans on the vavle covers didnt know if the aftermarket fox style was identical to the standard fox covers. The search came up with really nothing

Sucks a lot of stuff didnt come with the transfer..

russ8825 · Nov 6, 2011

The trickflow valve covers also have a lot of room.

mustangspartan · Nov 7, 2011

Was looking at those already but the fact they want a decent amount over these ones is not in my budget right now.. Maybe on the next build.

Mrstangerbanger · Nov 7, 2011

Im running chrome foxbody valve coves and have no problems at all .. Im also running a 3/8 spacer for my intake... U have to grind off the baffle inside the valve covers and they will clear no problem.. I can send pics if you need them

mustangspartan · Nov 8, 2011

Hey thanks if you want to post them or send them ill run it threw my photobucket. Im just wanting to make sure that people can also see so if they come to the site they can see what has been done and what works

I was expecting the baffel for sure and got the 1/2 spacer for the cobra intake.. Im hoping the TB wont be a issue from what ive read so far it shouldnt. Always good to get people that have done it to give you a heads up..
