Hello. i have noticed a pulsing HISSING sound near injector on the alternator side.
it is sweet down in the injector seat. how can i figure out what is wrong? i suspect a blown gasket.
but not sure.
it is a tight spot. but if i spray brake cleaner down where the injector is to loosen the dirt. diesel and oil.
and use air compressor to blow out the residue.
could i spray soapy water down there. if its a gasket would it make bobles?
i had a leak on the injector pipes a year ago. on the same injector. so all the pipes is new.

Sounds like injector washers , happens when injectors come loose n carbon causes a lift , u need get them replaced and injector seat cleaned of all carbon , brake fluid over night good to soften carbon

If its a 1.6hdi its a common problem.
You could use washing up liquid mixed with water to find out where the leak is.

little diesel smell. but it is a black sirup(gunk) down at the bottom of the injector. i dont know how tight 4nm is. but the injector nut was loose. i could turn all of them 2 times before it startet to feel tight. then i tighten them with care. the sound is still there. but not as high sound.
