Boost leak test results...a little help please

[bigbro6785]

Ok I finally got a boost gauge and did a boost leak test. When I installed my boost gauge I took the car for a test run to see how much boost I was making. When I would take off I would get about 10 psi, but as soon as I hit 4500 rpm, it would drop right away to 6 psi.
I did the boost leak test and found out that my stock BOV was leaking air at as low as 4 psi, so I know I need a new BOV. There was also air leaking from the big center screw on the throttle body, and also from where the injectors connect to the IM (mostly the 2 center, and a little from the one on the far right). My question is how would I go about fixing these 2 leaks? Maybe a little lock-tight on the screw? Are there gaskets between the injectors and the manifold? Thanks for any help.

The BISS screw uses an O-ring to seal against leaks. In older cars, this O-ring tends to dry up and get either brittle or deteriorate. You can try to find a replacement O-ring at an auto-parts store or hardware store, get one from the dealer, or from a vendor. Here is the individual O-ring, and here is the O-ring, new BISS screw, and new cap together at SBR. When I replaced mine, I replaced the whole set. The old O-ring was flat and gray and had chunks missing from it. The new O-ring was round and shiny and black. Big diference. Don't use Loc-tite on the BISS.

The injectors also use rubber o-rings as lower injector seals, but they're quite thick. Here is the link to find what they look like.

Good luck.
