One of my EGR base bolts stripped and the hole was massive so I tapped in 2 M10 x 1.25 bolts. I am trying to get rid of a leak on the base of the EGR, the surface seems to be uneven for now I believe this felpro make your own gasket stuff is holding up any suggestions on what to seal the surface with? Will this effect the drive? My car gave me a Code 32 on the way home from the gas station after tapping the hole with no gasket.

Another issue I believe, my car only has 15 Hg of vacuum at idle. Is this normal? It does bounce between 1 Hg. I wonder if this relates to the EGR or possibly my Idle..I just adjusted it to the best of my knowledge getting the car in closed loop at 550 RPM is ridiculously hard..had car running for along time yesterday.

 

im no expert on gasket, but the cut your own, if u have the patients and a stedy hand should do ok, use some rtv gasket seal too, just dont let it leak into the EGR hole. but like i said, im no expert.
good luck

 

Well, just last week, month, and months had no EGR code..decided to tap the stripped bolt and cure a leak now I get Code 32 after awhile of driving...wtf...did my EGR go bad or something?

 

I broke those same bolt off a while back and had to tap them out, and when I put the egr back on I just used that copper(orange) Rtv stuff and no issues at all, youll know it if leaks...sounds like popcorn.

But id look over the wires and the vac lines connected to your egr.

Id try to help more but I have a 1991 and my top section of the EGR looks nothing like yours..sorry

 

I put high temp RTV down on the EGR base with Felpro make a gasket. Then I removed the EGR cleaned it with a wire brush and put some RTV on the base of that as well, maybe the inlet tube is leaking because im reusing the gasket? I dont know...might break out the propane torch tomm and try to spot a leak. Maybe my EGR is just bad, but 15 Hg sound low to me.

 

my EGR looks nothing like your either..mines more of 3 post looking things and a wire plugged in. mines a digital i belive, yours must be a michanical? eddi woul know more then me

 

Is there a difference between the manual transmission EGR and A/T EGR? I will probably just buy a new one, but advanceauto only shows one for the M/T

 

idk, i didnt think that the tranny had anything to do with the EGR but that shows how much i know lol i have a M/T and mines a digital style..thisISNT mine but its what my looks like

I dont know much about that EGR since its a vaccum one.

15" of vac is a little low i think? Mines making a little less then that but its got a cam and ported heads, so Id look at all your vaccum lines arround the EGR, the back of the manifold. They might be cracked since those things are old. A vaccum leak makes the car run bad I know that from experience though...

IIRC about 18-22" of vac is a good number for a stock V6 thirdgen. Depending on the altitude you live at, and to be honest I never checked my vac in " when my car was stock so I dont know for sure. Search a bit and im sure youll find something of someone will chime in.

 

Bought this

Hope it is the correct EGR for my car.

 

It looks like the right one, you could of just bypassed the EGR. You need it but at the same time you can go without having it. Its just emmisions stuff.

 

I read some threads on here, seems people are split about whether it effects the car or not. I got it for $30 bucks, I think this is just the newer version of that old EGR on my car. Hope it works, till then I will drive with the annoying orange engine light.

 

Got the EGR didnt come with Orifice washers dont know if that matters..

 

2.8Ls make less vacuum then the sbc, 15" is on the low side, 16-17" is normal, you said the needle fluctuates, so you might have a slight misfire, vacuum leak at a port, a dirty injector. Check your ign. timing, you might want to bump it up to 12*.

 

Update: Fixed the Code 32 I believe. I bought a new EGR (Wasn't needed though), and put it on still got the code. Then, I took it apart (everything vacuum related to the EGR) and blew compressed air through the lines. Alot of metal gasket material came flying out of the input to the solenoid, must of been from the deteriorating gasket at the base of the EGR pipe. Much better throttle response, and no code..woot. Going to check my vacuum levels soon.

Also had to change my spark plug wires...1 broke in half easier than bread...stupid wire set-up, bought 2 packages of spark plug wire hangers and re-routed them.
