egr system delete

[godfearingman]

Hi I have an 94 GT I'm in the process of fixing up and I'm wanting to delete the egr system especially the piping to make it easier to work on and for looks as well. How would I go about doing so and the car be drivable? Have to get the computer flashed to get rid of the the egr system in the computer?

You will need a chip with a tune to delete the egr or you will have a check engine light and idle issues.

I made a block off plate with some scrap steel. Made a cork gasket. Just traced it all from the EGR valve. Pretty simple. I think I used a JIC hydraulic cap on the exhaust, don't think the threads were 100% match, but it was close, got tight, and seals, all i can ask for....

I'm mainly wanting to get rid of the piping to make it easier to work on the car especially number 4 plug its a PITA to get to with the egr tube/pipe right next to it plus planning on installing headers once I get another transmission put in in the next couple months.

Just cap it off and leave it plugged in. Go to lowes plumbing section and get 2 caps, 1 for the header 1 for the EGR.

Thanks I hadn't thought about doing that, that won't affect the performanc of the car or throw codes etc?

Nope, it just blocks exhaust gases from recirculating.
What do you have the timing set to?

Don't know I've only had the car about 3 months now still in the process of fixing it up. I don't have a timing light but planning on buying one soon. Why will capping it off affect timing or something?

 

[lutter94]

When you buy your timing light I highly recommend this one. I love it. Has a tach, just in case you need to recalibrate your tach down the road or something.

I definitely don't have that kinda money to spend on something I might use once or twice was planning on getting $20 one from Harbor Freight.

 

[lutter94]

lol ok, at least get the one with the advance dial. its like 30 bucks. make one mark on 0 deg. and adjust.

 

[SNorange94]

It's not going to mess with your timing. Some people say that it leans out the fuel mix a bit, so when you time it listen for pinging.
I had my timing set to 14* BTDC and it ran great.

 

[godfearingman]

Just being honest if I had that kinda money to spend on it I would've done had my transmission replaced doing things when I can and have the extra money. Here's the one I'm planning on getting. http://www.harborfreight.com/xenon-timing-light-3343.html

this is worth the 10 extra dollars. dont forget your 20% off coupon.

 

[godfearingman]

What makes it worth the extra money? The adjuster dial or what?

 

[lutter94]

say you buy the cheap one. you have to mark the balancer at what ever timing you want to set it at. It's hard to check what its at currently without the dial.

With the dial, mark zero deg on the balancer, and fine tune the dial until the mark lines up. Want to set it to 12, turn it to 12, then set the dizzy. Want to try 10, turn the dial to 10. Otherwise you'd have to make multiple marks on the balancer.

 

[godfearingman]

Ok I've never used a timing light or set timing before

 

[ttocs]

good to know as I need to get one. The way I see it is that while a timing light isn't all that difficult/technical of a piece it would still be really easy to screw up and cause problems.

 

[lutter94]

It's real simple. Just be sure to unplug the spout connector before checking/adjusting. Any questions let me know

You guys are forgetting the cheapest block-off out there for the header! Cut the tube, pull the the screw part that screws onto the header off, throw a penny in it, and tighten it down. Ghetto? Mehhh Kinda. But fits perfectly, the copper will give a little bit and seal good, and if it ever blows out, it literally costs $0.01 to fix. When I deleted my EGR junk on the red 94, that's what I did. First penny would have lasted but my buddy "engraved" a X into it and wouldn't you know, it split along those lines. But the 2nd one was in the car for 6k miles before I sold it with no issue whatsoever.

Can't remember what I did on the valve itself, but I left it attached for the time being.

I think a 351W mechanical fuel pump block-off is the same dimensions as the EGR valve on the intake. It may be the 351C or something oddball like that because I'm pretty sure the 302 and 351W would be identical and I know it wasn't a 302 one because whatever size it was was something we don't stock at my store... Idk, quick search would probably turn up the correct one but there is SOME fuel pump block-off that fits perfectly over the EGR valve ports on the intake if you do remove the whole valve.
