Decided to attack the fuel leaks.
I noticed when running today the car was leaking fuel in two different places, one more than before. I knew the manifold had to come off. one problem, even the top manifold could not be removed without lowering the engine (contact with cowl) I thought I would have to remove the whole k-member with engine/trans attached. Sit and think....
Came up with a simple plan to get me some room with the intake man.
Unbolt 6 k-member bolts (leave struts bolted) and disconnect the steering Coupler, raise car. well, it worked.
Removed the manifold/serp belt/alt bracket and started her up. Fuel leaking out of #8 injection line at the pump, it was loose, the second time this has happened. Checked line-to-injector, no leaks. BUT!!!
On the passengers side the injector return lines are leaking, well.... seeping. The drives side is dry as a bone.
Lift pump the culprit? Too much supply volume/press????
The lift pump I am using was set at 6.5 psi, 120 gph. Put a pressure gauge on the fuel drain and adjusted lift pump (internal reg) to the recommen 4.5-5 psi. Well the return lines still leak on pass side.
My thoughts
-prob too much lift pump, trying to return excess fuel at idle (it's gone push/leak out somehwere>? Excess fuel bad for lift pump??
-or the routing of the fuel lines (fuel tank at higher elevation than engine)(a.ka. fighting gravity. I noticed on the c2500 pulled motor from, the return DOES have the help of gravity. Electric
return fuel pump???
-Fixed injection line leaks, car runs 100% smoother.
-fuggin weaping freeze plug
-could these solid engine mounts be vibrating the car apart? loctite all bolts
Included a couple pics of the manifold since it is off.
Is the top intake the L65?
What makes it the designation L65?
Took a look at the manifolds with the CDR port on it. should I drill/tap for a hose barb fitting and attach it to the intake? This atmosphere vent is not so eco-enviro.
Port the intake? i've ported a set of cast iron heads and one aluminum set. Turned out alright on the flow bench and the cars they were installed in.
Suspension: let the car sit at ride height, and my oil pan skid plate is about four inches off the ground
May fab some 1/2"-1" strut spacers, yes a lift for the Camaro. Yet, it doesn't sit any lower than any 4th gen V8 F-body w/lowering springs. I ahve dealt with the issues of Lontube headers on a lowered LS1 F-body, my old one. I had Eibach springs about 2 inch drop and pacesetters. Bad bumps on the highway would casue a ball of sparks. Not good, but 2 years of driving and being careful I never blew through the pipe.
but with this car I don't want to be careful. I want to drive it like I stole it. Everyday. I guess we'll find out.
that is all.
