After taking the car from the mechanic after about 5 weeks, I started working on the remainder of mechanicals, there car was throwing codes for:
*secondary air system
*lambda sensors
*oil in coolant
*coolant temp sensor failing
*coolant hose rubbing on ac wheel
*oil cooler leaking oil into the coolant
*mirrors not folding or adjusting
I also wanted to look at the fuel filter and crank case breather hoses its a common oversight.
On the 2.8 there are 2 breather hoses, the first one (1) can be replaced easily while for the other (2) one intake manifold has to come off:
