CMI headers
I just bought a 2005 525 EFi engine with the CMi sports headers.
The headers was tested with a leak down test by the previous owner right before i picked it up, and i have done 2 different pressure test's with the headers fully submerged under water, and not a single air bubble was detected.
Yesterday i started the engine on a stand, and i could see some liquid in the starboard header.. The port one was dry.
I stopped the engine immediately after i noticed this. It was running maybe 4-5 min..
It did idle fine, no misfire or anything. Extremely loud though, they gonna love me at the harbour
I don't understand how this can be water when the headers have been going through the tests with flying colours.
Can this be fuel? Can a bad fuel pressure regulator cause this, or a stuck open injector/ injectors?
I did clean the injectors a couple of days ago, but did not pressure test them. And they only opened when given 12v.
Another thing is that, after i started the engine i went my sister place to pick up something and the first thing she said was, that i stank of fuel.
And so does the oil, so it must be, right?
