1) The crossover on the exhaust side has started collecting a fluid. It seems to be leaking out from the connection. The fluid is black but has no odor. My coolant level does not drop.
2) Is this the overboost control? It gets dirty/fogged under the nipple with oil. What does this part do and is it normal for it to mist like this?


This is a 90 350 sdl w/ 168K miles. 68K miles since rebuild. Uses 1 qt of oil every 3000~4000 miles.

Thanks
