the oil pan cannot leak fuel.
what makes you think this? smell? did you actually find liquid gasoline?
many of our cars have flooding problems. have you ruled that out?

do a search for -pulsation damper- if anyone says anything about leaking fuel they need to check into that b/c it is possible that your car could catch on fire

if your car floods at all, your oil will smell like gas

my car does the same thing currently....DONT DRIVE IT!!!!!!!!

there are definitely some threads for this. go to the one that is titled "I smell gas...Lots of it" it has the pictures that will show you where to look. but it is a small brass drum looking thing underneath the intake and you can see it without taking any parts out. it has a small screw in the end. and if you start your car and look at it there will "probably" be fuel coming out. it is on the passenger side pointint towards the front.

i doubt your PD is leaking that much fuel. (im not saying you dont need to check it!) in my opinion, if it is leaking enough for you to catch it with your hand, its probably the crappy rubber fuel lines going to the injector rails. (the clamps on these are crappy too)

RX-7Impreza

on the contrary,

the screw in the center of my pd came out and it spits fuel like a son of a biatch. it is always good to check

hey pj

I just read your psot on the other thread and the reason mine is coming from the screw hole in the pd is because my screw worked itself loose. in other words i have screw loose sorry i couldnt resist the bad pun

it is just a suggestion and i doubt your problem is the same

With the engine not running, you need to pressurize the fuel rails. Just turning the key to the on position does not do this. You have to jumper a yellow in color electrical connector near the r/h strut tower. It has two wires going to it. It is not connected to a thing. You get a piece of wire and put one end in each socket of the electrical plug. Then turn the key to on. The fuel system is then pressurized and your fuel leak should start to drip. Just keep looking until you spot the source. Don't run the engine at all until you find the leak. Go to http://www.iluvmyrx7.com/Technical_I...ice_manual.htm and download the fuel section and you'll see the above procedure for pressurizing the fuel rails. Worse ocmes to worse, the fuel leak could be under the intake manifold and you'll have to remove it to find the leak.

Be sure to check your PD and the screw coming out or backed off, when the screw comes out or backs off it restricts the fuel going thru the dampner to your injector rail. This restriction could cause backup press to your hoses and if there old and brittle or the clamps are corroded they'll leak to. You need to jump the fuel system and find the leak. If the dampner isn't pissing fuel another indication the screw is out is it will have a hissing sound coming from it. They only **** when the baffle ruptures. Mine wasn't pissing out it was hissing and I could smell fuel. I popped the cover off the screw was just rattling around and you couldn't even blow thru the inlet tube going thru the dampner, once I put the screw back in I had no restriction. I replaced it with a new one from Mazdatrix.com 120.00. Hope this helps, let me know. Gary

That may or may not have been your leak. If it was, it's not fixed. Even w/ the screw out it shouldn't leak fuel. The diaphram is ruptured and you need a new PD or you could JB weld it. My screw was in and I had no leaks but I epoxied over it for insurance. Many people have done this w/ out any problems including me. The concenses seems to be that the rubber fuel lines provide enough flex in the system to "dampen" the fuel pulses as the epoxy won't let the diaphram screw move any more. The screw just limits the travel of the diaphram. If you crank it down you'll surely rupture the rubber diaphram.

If your leaking that much fuel I'd look seriously at all the rubber fuel lines and even the injector o-rings.

NO, DON'T JB WELD THE SCREW IN!

Buy a $10 metric banjo bolt and replace the PD.

We just went through this on the fc3s.org mailing list.
Someone posted the Earls fitting that replaces the PD with a metric banjo bolt.&nbsp Unbolt the old PD and screw in the new metric banjo bolt - pretty easy.&nbsp Sorry, I don't have the part number with me - maybe someone else does?

what the hell is a banjo bolt

JScott

EAR-807691 from Summit 12mmx1.25 thread.

This would be the preferred way to fix it. With it already leaking I'd definately replace it w/ the banjo bolt. Mine wasn't leaking yet and I tend to keep an eye on things so the epoxy worked for me.

Amm..All of this is really good info, however; where exactly is this little screw located? I have looked for it but I cannot find it. I am sure it really isn't all that hard to find but I really could just use some help, thanks.

FDxc

i have the same problem like all of you.. ok does anyone have PICTURES or diagram? maybe it'll help me and others understand better.. ack.. i h8 leaks.

FDxc

i could still drive with this leak right? ... Is this engine oil?
