OK, SUPERSTEVE. I have 120K not miles Kilometers so about 72K miles. I just replaced the 2 oil vent hoses in the back of the engine. She is a Oct 2000 vehicle 4.4i (rare in Italy) don't really trust many mechanics to do the work. I must be honest, when I replaced the 2 hoses I thought I had to undo the U shaped aluminum tube on the top of the engine. I just loosened the bolts and the tube, didnt remove it though, but did wiggle it loose a bit. After I replaced the hoses I managed to put the aluminum tube back in place. This problem did exist before I replaced the 2 oil vent hoses. I dont have a diagnosis tool to test the fuel pressure.

What hoses should I check? Where is the air intake boot? Is that where the air filter for the engine is?
