When you replaced the calipers, did you also replace the brake hoses? Why did you replace the calipers?

Did you check the master cylinder for leaks and brake booster for brake fluid?

The tickeing sound can be an exhaust leak. Check the manifold gaskets and EGR valve gasket and pipes. The EGR pipe that goes into the intake manifold can also get blocked with carbon buildup, assuming yours has an EGR vavle.

Your oil leak can be caused by a leaky rear seal. Also, the valley under the intake manifold has a drain hole at the rear left that drains onto the bellhousing.

A pressure buildup can also cause an oil leak past the rear seal. You have to check the crankcase venting system. Take off the air cleaner housing and check the small pipe under the passenger side for blockage, mine had it. Clean it our if it's blocked. Next, pull off the driver side hose from the valve cover to the cold start valve housing. There is a small hole that can become blocked. Push in a small pointed object, a small drill or the point of a test light, to make sure it's clear.
