How do you remove the timing cover, I removed the four hidden 13MM bolts under the oil pan, and all the 10mm (27) bolts on the case itself, I have spread 3/8" at the correct pry notch, its loose on both heads, can wiggle it, but concerned may damage it. (BTW all top engine parts are off and so is the engine mount on that side and the oil pan. Suspect there is a pin somewhere but can't find accurate documentation for this PentaStar 3.6L. Also the harmonic balancer was missing its alignment pin is that normal. Ordering new balancer, and full seal/gasket set.
Appreciate the help. This is a great web site. J

- Clean the engine timing cover, cylinder head and block mating surfaces with isopropyl alcohol in preparation for sealant application.

Engine assembly requires the use of a unique sealant that is compatible with engine oil. Using a sealant other than Volkswagen genuine Engine RTV Sealant may result in engine fluid leakage.

Following the application of Volkswagen genuine Engine RTV Sealant to the gasket surfaces, the components must be assembled within 20 minutes and the attaching fasteners must be tightened to specification within 45 minutes. Prolonged exposure to the air prior to assembly may result in engine fluid leakage.

- Apply a 2 to 3 mm wide bead of Volkswagen genuine Engine RTV Sealant to the front cover as shown in the following locations:

Three cylinder head bosses (1)

Right and left flanges (2)

Four cylinder head to engine block T-joints (3)

Cover to right cam chain tensioner gap (4)

Do you have some good pictures of the case cover itself? I would like to see the bottom, where any alignment pins are. Is the idler pulley and power steering pump pulley removal required? Looks like you could remove cover with out those or the frame member removed.

Is the diagram with the arrows the correct pry points for removing the case cover?

I have removed lower oil pan, and the 4 bolts that appear to hold the timing cover on, why do we need to remove the upper oil pan assembly?

Thanks appreciate your help, learning a lot. J
