ok..all of my emissions are gone, but i still see 2 things attached to my exhaust. 1 is a tube that comes from the middle of the pipe and is blocked off, the other is connected to the intake manifold, i took it off and there's a gasket with a small hole in it..cranked it up and it ran fine (i could hear exhaust through the tube) what can i do with this thing??

second is a tube going from my master cylinder to the intake manifold. is it like a vent or something? i removed it, crank, HUGE leak, put a stud in the tube on the intake mani..runs fine. whats it do?

REVHED

Mate, the line that runs to the master cylinder is for your brake booster. Put it back on there.

grr..ok that one can go back. but what about that tube going to my tailpipe??

If the gasket has a tiny hole and is kinda shaped like a triangle, you can plug that hole up.

the hole is circular..the gasket is kind of strange. almost an oval..only 2 of the sides dip in.

2 sides dip in?

It is a metal elbow type thing that has a rubber tube connected to it and the elbow mates up to the intake manifold... I'm pretty sure you block this one off.

if you are standing on the side of the engine with the exhaust manifold, this tube connects on the left side. it has 2 studs coming out of the intake manifold...with a gasket that looks like a restrictor plate(the hole in the gasket is much smaller than the hole in the tube/manifold) i cranked it and couldnt feel anything on the intake manifold, but there was a slight suction come from the tube..in addition to the sound of the exhaust.

Yes, cap it. Its in the tutorial. The one to the exhaust. The one to the brake booster is necessary, just like REVHED said.
