Another progress update.
Thanks for the tip about the hidden bolt on upper left of timing cover. The timing cover was very difficult to remove, and as I removed it, I saw why: the nylon guide (ALL nylon) had disintegrated and pieces of it were jammed in and around the oil pump cover. Apparently a piece had got caught between the crank gear and the bottom of the timing cover, because it cracked the oil pump cover. Believe it or not, one of the local Nissan dealers had an oil pump cover in stock for $55. Amazing.
Also, even though I had to remove the a/c compressor, I was able to grind off the top of the metal on the adjustment slot for the a/c compressor mounting bracket enough to clear the lower RH corner of the timing cover, so that I didn't have to take it off as well.
Upon closer inspection of my old oil pan, I noticed pin-sized bits of corrosion that had worked their way through from the outside to the inside of the pan. I found another pan (banged up, but solid) at a used parts place for $40.
When reassembling everything, I noted that the Chilton's maual calls for 56 lb-ft of torque for the oil pan bolts, which seemed suspicious. I can't imagine cranking down on a cork gasket with that kind of pressure. So I tightened them all the same with a 1/4" ratchet.
I am hoping to finish bolting everything back up tonight.
Total costs so far:
Timing gears/chain/tensioner kit $120
Oil pan gasket ~$12
Valve Cover gasket ~$18
bottom front motor mount ~$65
stabilizer bar connection links ~$60 for both
oil pump cover $55 new from Nissan
oil pan used from junk yard ~$40
Fingers crossed! More tomorrow.
