does a s4 motor have secondary injector or just the two? two primary but does it have 4 total?

 

Rotary engines are made to rn with Primary injectors below 3800 Rpm and above with Secondary injectors.
Best thing to do,NO offense is to Tap Google and punch in "How does a Rotary engine work?"
It is quick and will explain things real quick and you don't have to wait for answers!

 

i did google for the injectors but come up with different answers but never got a solid answer off of google that why. thanks tho i just replace the orings on my primary injectors thinking they were the ones leaking but the secondaries are the ones actully leaking so now i have to do that

 

Search YouTube great videos there on rotory motors and everything else

 

make sure you have everything sealed up good,fuel leaks are no joke!

 

The Op didn't mention any fuel problem.He just wants to know how many injectors are on the engine.

 

Looks like a fuel issue to me haha.

 

O rings..vacuum leak..I stand My ground.
I'm stubborn!

 

I was just pointing out that he thinks it could be sec. Inj. You prolly right though.

 

actually NO.....YOU are right.
Grommets are Vacuum leak.O rings would cause gas to leak at the rail.
but in a way the Op didn't even know he had secondaries.
So 50 to you..50 to me..heh,
We'll split it!

 

yes, FC/FD have 4 injectors. FB had 2 on the GSL-SE.

 

The first set of injectors that you rebuilt are actually the secondaries. The primaries are hidden under the s-turn of the intake manifold. To get to them, you will need to remove the top half of the intake manifold. Be sure to order a new gasket. If you attempt to re-use the old gasket or make your own with ghetto putty, then the engine will very likely develop a vacuum leak and you will be on this forum again asking why your engine runs like crap. The answer will be that you did not spend $6 on the correct gasket.

Now is a good time to replace the EFI hoses, clamps, fuel pressure regulator, and pulsation damper. Also, I recommend that you label all of the hoses on the intake manifold prior to removing them so that you know where to attach them when you reassemble the parts.

The 2nd Gen forum has a FAQ where you can download a free manual (the 88 manual works for all S4 models). It is not a good idea to work on your car without the manual, and especially note the torque specs for any of the aluminum parts. If the torque is not listed in the procedures, then see Chapter 30.
