or at least I think it is but what do you guys make of it?
ive been getting a decent amount of oil appearing on the outlet end of the aftermarket front intercooler. its dripping onto the radiator support rail below so we're talking about an unusually large amount of oil here not a trickle and its gunky borderline milky oil. not the usual mist spray of oil but inside the silicone elbow hose there was a nasty pool of it. i cleaned that out 2 months back and its all returned. no mayo in the oil filler cap or engine breathers.
now ive noticed oil around the elbow on the inlet hose side of the intercooler and the hose joiner from the turbo outlet to metal boost pipe leading the intercooler also has a wetness around it . both ends very wet. i cant tell if it oil contaminated with water. i can test for that easy enough tomorrow but engine wise compression is spot on and there is no oil in the upper intake pipe pre-intake manifold (bar a tiny amount of mist on the bottom) and there is no smoking at all. it drives nice but ive noticed a roughness to it especially at 2500rpm any gear. 60mph is rough at those revs but go faster and its not so bad.say beyond 3-3500rpm.
ive noticed the brand new expansion tank fitted 6 months back is no longer nice and clear but has developed a light brown residue inside it but im not losing any water and oil consumption doesnt seem OTT.
not sure if its related but i have oil leaking off the oil filter even though thats on nice and tight (well not overly tight as they say hand tight is enough). engine breather is clear and the firetrap is new. ive not inspected the turbo yet but could do with some thoughts as to whether this level of oil is normal or if the turbo is dying as far as the seals go.
the turbo is an IHI watercooled VL7 and im not sure if its possible for water to cross contaminate with oil if galleries crack into each other .....
oil pressure takes a step drop to about 1.4-1.5 bar on the gauge when the motors hot but it used to stay at 2 bar when hot all day long.
im just a bit lost now on ideas and what it could be.
