Leaking injectors

[Ty#0318]

I've found fuel in engine oil. Started with checking injectors. They leak.
Two of them are very bad and the rest are not the best.
Is it normal that oil is mixed with fuel in this case?
My injectors:

Do You know what injectors are they? Are they correct?
I've found that I have no original fuel pressure regulator...

Do YOU think that replacing injectors will solve my problem?

Re: Leaking injectors

Maybe be the lower intake manifold gasket is damaged andleaks fuel into the oil valley under the intake

Re: Leaking injectors

the bosch is the original regulator for these.
Id check the pressure and make sure its in spec 38-40 psi

Re: Leaking injectors

When you say they leak, where are they leaking?

If they're leaking between the rail and the inj's, which your photos seem to indicate, then there won't be fuel in the oil. UNLESS the lower o-ring is bad and the leaked fuel is drawn into the intake by engine vacuum. (Unlikely) If the inj's are passing fuel (IE, not shutting off all the way) then, yes you will have fuel in the oil.

I'd be inclined to think that the regulator is bad and is passing fuel into the sense line thence into the intake.

Have you checked the plugs? If one or two show way rich then maybe those injs are passing fuel. If they all show rich then I'd go back to the regulator.

Have you done a fuel system pressure test?

Just my :2cents:
