How hard is that upper timing chain gasket to replace? Mine is leaking due to a bad PCV. I have not found a good DYI guide for this one.
Its a nightmare, to take off the cover you need to remove the motor mount bracket (the bracket that connects to the engine), and removing that bracket is about 95% of the labor and time. Its a nightmare because the (3) #12 triple square bolts that hold that bracket are torqued on hard and there is only about 2-3 inches of clearance between the frame rail and bolts.
Essentially this is what it takes.
* Jack up the car and secure with floor jacks
* remove splash guard (so when you drop sockets they fall to the floor)
* remove dog bone mount
* grab a piece of wood and jack up the passenger side of the motor a little.
* remove noise pipe, all the bracket and plastic near the windshield fluid fill tank and coolant expansion tank.
* remove passenger side motor mount
* remove the motor mount bracket from hell (this will require lifting and lowering the engine a few time to get a good angle)
* loosen the bolts that secure the dipstick
* remove cam shaft magnet
* undo the 5 bolts that hold the timing cover
* remove cover
* install new gasket
*reinstall in reverse direction
anyone who says its a 20 minute job has no idea what they are talking about
