My alternator went bad yesterday so I'm in the middle of replacing it. While tearing down the car to put the new alternator in I noticed that when I took off the inter cooler piping (fmic) a half of a coffee mug worth of oil pours out of the bi pipes, inter cooler, and surrounding areas. All plumbing from the accordion hose to the throttle body have oil residue. This really scares me cause I know this is one of the symptoms of turbo failure, as when my ko3's went.
I recently replaced my spider hose because the cap where the n75 valve connects to snapped off, don't really know how long ran like this, but it couldn't be that long cause I'm under the hood at least every 2 weeks at minimum, to check for stuff like this. At the time of replacing it I noticed a large amount of blow by, there is always a little, but this time is seem like a significant amount more than normal. I chalked it up to the pcv system having a leak (cause of the snapped spider hose) and cleaned up the y-pipe and surrounding stuff.
The car was making full boost as of yesterday and with no smoke coming out the tale pipes. I do not think the turbo's are bad, but what could cause this much blow by to happen??
The car is torn a part now and would like to figure it out before it goes back together, just need to get it back together soon as it is my dd. Recommendation, Thoughts??
