Well I got the lower timing cover off today. It was a lot of time but I did it a little different this time and it came off no problem. This time I put the right upper motor mount back on after I removed all of the area parts. Then when I was ready to remove the timing cover I put a jack under the crank case assembly and removed the upper mount. When I pulled the cover off I had to lower the jack just a little to clear the frame and it almost fell off.
I am thinking the problem may be that I used the cheap oring gasket for the oil hole that came with the rebuild kit, it slides around and really feels loose compared to the old stock one. It could very well result in a decrease of oil flow and that is the spot where I had an oil leak in the timing cover so I know it was not sealing. I have a new Nissan part to replace it with. Also the little plastic part I found was from one of the new guides and both guides are loose to the touch so I am thing of replacing the with better quality. I will see what happens.
Any updates?

Well I have been waiting for a couple of parts, I bought a Nissan lower timing chain tensioner guide and installed it while I had the lower timing cover off.
Got the car back together and running today, something is still not right. When it warms up it still makes a lot of noise in the top end. I also have been noticing a slight misfire that I can hear when I run the engine at a steady high rev, this was there before.
I plan to take it to the guy that does my engine work and did the head so he can listen and give me his opinion. I was not happy with the work on this head, first he did not tell me it was the first Nissan head of this type he worked on, he ground the valves and the adjusted the stem height by grinding the valve stem instead of using shims. He charged me $600 for the work when I could have had a rebuild one delivered for a little over $300. The heads I used before I lapped the valves by hand a never had a problem. I already have the parts so I guess I will pull the head have it checked out and install a head gasket.
If that does not work I can get a tested used engine locally for $550.
I got the head off today and the only way I can describe the head gasket is "mush". The entire head gasket is shot. I took some pics but cannot post right now. One of two things happened, when I over heated the engine it cause the failure or it was the cheap head gasket I got with the engine kit on ebay. Ether way I can see the that the entire gasket completely broke down and I am just going to clean the head and block to replace the gasket with new head bolts.
I started to reinstall the cylinder head today. I got up to 59 ft lb of torque and the number one head bolt broke. I went to auto zone and showed them that my torque wrench was calibrated and certified in Sept. I also had the tech at the shop test my wrench at 59 and it was right on the money, so they could call to verify if they wanted. Since they had no idea what I was talking about they ordered me new head bolts and a head gasket under warranty and when it comes in I will start over. Head bolts made in china.
Just an update motor is back together. The headgasket is fixed but now it is making another type of noise. I am almost positive it is the valves. I check the lifter to cam and they are way off for the most part according to the FSM. I ordered the shim install tool and when it gets here I will begin to replace the discs. I did read some where that the shims are no longer made, is that true?
Quick update, I replaced the engine with one from a salvage yard. Runs good, lower radiator hose warms up after the engine reaches temp the way it should. I am going to take the other engine apart and check it out. I have some ideas but will wait till I get it apart.

Wow great to hear you got the car running again. Looking forward to what you find with the old engine.

I do not have time right now to do any engine work, I have found that it is easer to find good used engines and swap them out. I also just bought a 96 200sx.
