oil in intake

well hey guys ive been in ashville for two weeks on a job at the blue ridge paper plant. i got back today and decided to drill the intake for my boost gauge and noticed some oil in the intercooler pipes. it wasnt a lot but still enough to get my attention. what would cause this? is it something to be worried about? i saw a thread about this before but now i cant find it.

oil

A certain amount is to be expected. There will always be a residue in them.

It's residual from the crankcase vent. A certain amount of oil vapor get into the intake from the CCV. If the oil level is overfull it can be worse than normal. The only way to eliminate it is to reroute the CCV and vent it to the atmosphere or install some sort of oil trap inline with the CCV to prevent the oil from getting to the intake.

thanks guys im wondering if that residual oil in the intake will get sucked into the boost gauge and cause problems. also ive noticed that there is some bluish white smoke at startup which seems to be worse when its cold out coming out the exhaust, is this from that oil in the intake

A dirty air filter will increase the amount of oil in the intake as well. When it is clogged the engine will pull air from the place of least resistance. As far as the smoke goes that is normally a good indication of injectors failing. Hope this helps.
