Hello,
My Corolla's injectors seal (which are saw like a rubber ring(not little O-ring) on the injectors in holes which they are entered in their manifold) are a little cracked and after many years lost their elasticity.
Around 2 of 4 of injectors on the injectors manifold we can see gasoline mark around injector entrance hole on the manifold. I've never seen even a little drop of gasoline, just see the gasoline mark(Like the mark of gasoline vapor).
Question is: is this dangerous for motor? I mean will be this gasoline mark(like gasoline vapor mark) on the manifold dangerous for catch fire or it is not very important? And why just 2 of injectors makes this vapor mark?(despite all the injectors sealing rubber rings are a little cracked)
Thank you very much

Anytime you have a gas leak, you have the risk of fire.

Just remove the fuel rail and replace the seals.

The fact that 2 are leaking and 2 are not is just luck.
