Cam Nuts
Yes, I have Searched. I just want some input on removing the cam nuts, as I expect this will be my next challenge. I'm not there yet, but perhaps tonight I'll be staring at those two nuts.
I figure the passenger-side one can be simply removed with a breaker bar if I can secure the crank. The chain makes a straight shot from the crank to the cam sprocket. Am I correct in assuming this will work beautifully and not damage the chain? On the driver's side, the chain does not make a straight shot from the crank to the cam sprocket. Does it make sense to stabilize the chain wheel support and use the same method on this side? Or do I have to use one of those noisy tools? Or one of those expensive 3-pin holder tools?

a breaker bar would turn the engine over. use it in conjunction with a cam holding tool. or do it quickly with an impact wrench and 46mm socket. the right one can be loosened with the tensioner in place. the left side tensioner needs to be removed, and a suitable spacer put in it's place to keep the chain in position while the nut is removed.

Thanks Obi-Wan. I hear you saying that I'd just need to remove the left tensioner and put something solid in there. Okay.
I am thinking the engine will not turn over if I can secure the crankshaft like we did with the Porsche Special Tool Number P934024856-359725 (old lawn mower blade). And I think it was you, John, who pointed out that my fasteners are 19mm bolts. That being the case, I am assuming they are not tightened to 400 lb/ft!

Thanks again, John. Here's an elegant thought, FWIW. Maybe on the left side I can turn the bolt, depressing the tensioner until I can get a pin in the tensioner hole, put the pin in and break it loose. We'll see when I get there.
