Ok. If you do end up cutting it off be very careful not to damage the nipple. It's holding the O-rings and it's aluminum. Did it go for a long time without good coolant in it ? I haven't seen them that hard to get off. Must be some hard ass buildup in there. If you blew most of the water out of the pipe maybe shoot a bunch of penetrating oil in the open end and let it run down there to the nipple area. Or if you do cut the pipe don't cut it right there at the nipple, to avoid damaging the nipple. Cut it a few inches away or something so you can get Visegrips on it to twist and work it loose.

Thanks Hamfisted, good advice… It will be Monday before I get back on it….
I had let my son use it for his business.. Since then it hasn’t been serviced good as when I had it..But, it was running pretty good when I decided it’s time for a timing chain change..279000 miles .. It was the best vehicle I’ve ever owned.. The body and inside look brand new, so It’s worth to put it back right.. At least for me, anyway lol
Thx again

Got delayed due to neck problems.. Old people problems..
Got the cover off, and again, I’m impressed by what I see.. chains are loose, but not enough to hit aluminum lol.. I got to get some cam locks before I go any further..
The passenger side tensioner looks pretty extended.. plastic on the guides look intact, but want know fully, till they come off..

After watching Brian’s video, I’m thinking update the followers anyway. I need a spring compressor tool.. Don’t like the idea of the screwdriver technique.. The lower end should go 500 thousand, so I think it will be worth it..
Now I have transmission fluid leaking from the transmission.. It was jacked up in the front.. I did undo the fluid check tube, at the engine, so I could get the valve cover off.. I moved it a little.. .. So much respect for you guys that done this for a living..
It’s all or nothing now, lol

Well after having the flu twice this year, I’m ready to get back on the project..
Thanks to Rock Auto my parts are here..
After taking the chains and hides off, I did find the passenger side tensioner went through the guide, and the chain ground it down a little.. So I have metal in the engine..
As soon as I figure out how I want to flush the system ( any recommendations?) I’m going to start putting her back together..

Personally, I wouldn't worry too much about "flushing" the system. The amount of time it takes to wear that much down would probably result in the metal being in your oil filters as you've changed them over the years. Might not be ideal but you could run some cheap 5w30 through it for a bit at first then maybe after 100 miles or so do another oil change with your oil of choice. I replaced a gazillion timing chains at Nissan and there was no formal flush needed after that job. I've actually seen more issues with the RTV dust when you have to clean up the all the RTV residue do just make sure to clean everything well as you go back together with it. Awesome thread though, it's great to see new life being given to this truck!
