Need some general questions answered

Seen a check on here that entailed putting your fingers under the egr valve and lifting up on it to see if it returned to its resting position under its own spring pressure. Well mine did but it's chock full of black greasy shit. What does that mean? And I have an RJC power plate. If my egr were leaking, would that plate stop it as it has the "egr block off" in it.

Also tried my old FPR because I finally got the pressure loss to replicate itself today. I tried relieving the fuel pressure before the job by doing what I read on here, which was to pull the fuel relay when the car's running. Well I pulled my plug and the car kept running. Does anyone know how this can happen?
So I did the other trick I learned on here and pulled the fuse instead. When I pulled the rail gauge and FPR there was still the same amount of fuel as there was when I did this job a while back without relieving the fuel pressure. Lol. Why does everything I read about on the internet never work in real life lol.

The oil pressure switch is a redundant fuel pump power source. When you pulled the FP relay, the backup kept you running.

It takes a long time for the car to run out of gas doing it correctly. Anytime I need to work on my fuel system I just let it spray out and get it over with.

I was thinking most people unplugged the pump connector at the tank.

EGR could test good but the stem could have a leak. http://www.turbobuick.com/forums/threads/egr-valve-leaking.394677/

The typical installation if you are still using the EGR is to drill a hole in the power plate. I guess the power plate could double as an EGR block off plate, but I would be curious to see if the gasket burns out and allows flow into the intake anyways. If you pull the fuel pump fuse and still have fuel pressure on the rail you aren't relieving the pressure. You could pull the fuse and try to start the car and run it out of fuel which I have done before on regular street cars but I wouldn't do it to my Buick. These cars have enough gremlins without trying to feed em

So if I don't want any more leaks, just fill the egr with epoxy and get a new check valve then?

 

[Raeban]

Some people like epoxy and swear by it. I have used it for various applications but usually when I don't have another option. I saw someone post a picture of where they tapped the EGR port and fitted a pipe plug that was pretty slick. That may have even been Earl's intake. I know others have the port welded up.

It was me. I'm pretty happy with how it turned out.

TT chips disable the EGR. If it's there are no leaks it's not affecting anything.

Earl is that a wood plenum spacer?
