Default Oil leaks and transmission leaks

so did my oil change yesterday and noticed two tings.

oil leak around passenger-side turbo. now im not sure if it is the turbo, or more likely, the valve cover gasket/etc. i can see oil on both and am assuming its the valve cover, however; if the passenger side turbo is known to leak from a specific area id like to know to fix it asap!

transmission fluid. jacked up the car and a pool of what looked like transmission fluid poured out of the bottom cross-member. now the fluid was clear on the ground, but apon wiping up with a paper towel, looked pinkish. my question is where could the transmission be leaking? i looked all over the unit as well as up into the bell housing and saw NO, path of fluid leaking out. now, my coolant temp sensor oring is shot and is seeping out coolant as i can see it pink stained around that area. is it possible that there is oil from the valve cover seeping out can flowing over the coolant picking up the pinkish color? or that the coolant is flowing over the oil picking up its viscosity? or is it more likely i have a transmission leak on my 6 speed?


thanks for the input guys

My money is on the cam adjuster seal.

Coolant.

Could be auto trans fluid if someone put the wrong stuff in, but your six speed removes that possibility.

You have to check the back the off engine for coolant leaks and also the after-run coolant pump under the intake. If there is a coolant leak, there should be traces on the transmission bellhousing or in the V-bank of the engine. If those show no signs of any leaks and coolant is coming from between the engine and transmission, the crank rear main seal flange could be leaking.

Oil leaks need to be checked with a mirror around the valve covers and tensioner seals. Start from the top and work your way down when searching oil leaks.

replaced the aux pump last year, can see colant residue on the bell housing, and no transmission fluid around the rear main, so im thinking it is the cooltan temp sensor and the bad o ring causing the trouble.

4driver4 - your right on about the cam tensioner, how much of a PITA is that to do?
