I have an oil leak coming from behind the gear case. I realize that this could be an ordeal to fix but I want to try and locate all the case bolts and snug them up to see if that stops it. What I need help with is this. I would like to see a picture of the bolts so I hit them all while tightening. Some of them seem to be hidden from direct view and I don't want to miss them. Could someone post a picture from the service manual or an actual shot of the case hold-downs. A count of them would also be helpful. A shot of the gasket would be very helpful too.

TIA and Happy New Year to all,

From the best pic I can see in the Manual there are 19 bolt's that hold the cover on. They torque to 18 ft. lbs.

 

Thanks AKDSLDOG

Is that for the cover or the case to the block. I understand that there is a gasket between the back of the timing gear case and the engine block. My leak is from the back of the case. The bolts that I am most concerned with are the ones that hold the case to the block.

For example one of them is the bolt used to install a KDP tab.

I believe there are 5 bolts behind the cover: one beside the KDP, one near the top of the oil pump, and 3 behind the camshaft gear, which can be accessed (sort of) through the holes in the gear, using a small mirror and a 10mm open-end wrench with some custom-bending. Rotate the engine as necessary to access these bolts.
Additionally, there are 2 bolts at the bottom corners of the housing (not behind the cover), and many of the cover bolts go right through the housing and into the block.

 

Thats what I am looking for! Thanks Torquefan.

Now, anybody got a pic of the gasket or the case without the gears inside but bolted to the block?

Thanks guys,
