Well its almost over. Hopefully I did it all correct. Took me four days so far.
I work for 3-5 hrs a day. Taking my time. Tomorrow i get to uninstall some linkage under the truck so i can remove the oil pan, clean it and install it.
then add oil and see what happens.

If you take your time its not so bad. I put bolts and parts in baggies.
Bought 5 cans of break cleaner and 5 cans of throttle body cleaner. I
cleaned everything i took off.

My alternator was literally covered in oil. I had a bad oil leak in the front timing cover. Cleaned the Timing Cover and Discovered it has cracks.
So i bought a new one. Old one has cracks in multiple places.

Also found my loud rattle. My tension guide was broken. Bouncing
around inside the timing cover.

I now just home and pray all was done correct.
till tomorrow......

good for you! And remember, it takes forever to bleed the lifters. Mine made a knocking sound for about 15 minutes before it went away

I just finished this project!
Its not hard, unless you set the oil-pump-distributor on tdc-exhaust.
Thats what I did. Truck wouldnt start.
Had to rotate crank to tdc-compression. Truck started after that.

My truck sounded like crap! Just like it says! It took 20 min. to settle down some and 30 min. to start sounding like it use too.

I would rate this timing chain operations a 7 on the

scale.
Its not that hard, but its not that easy!
Take your time!

I just inherited a 93 HB with 180k miles. Pretty sure my dad never did the timing maintenance but holly timing belt batman, that's a serious project and write up!

BTW Nice write up =)

I was considering doing this myself until I see what's involved, damn! i think i'll buy the kit and pay the labor at the dealership for just the timing maintenance.

I made the write up a little lengthy for the purpose of making easy to understand for a beginner. It's not too hard to figure out, but it is a lot of work.

Thanks everyone.

Great Writeup!

I've got a 97 2wd that I changed out the chain, tensioner, & sprockets a few years ago around 150K and after that all rattle was gone. It already had the metal guides in it and all I could find is the chain was very loose. I swapped everything anyway and this year the rattle gradually came back around 185K and now is as bad as its ever been at 187K. I think its related to the tensioner because I can take the valve cover off and reach into the front cover and push the tensioner to the left forcing the oil out of it and then start it up and (after the horrendous noise caused from forcing the oil out clears up) it will be quiet for about 3 months and then come back again? Strange. The chain is also getting pretty loose again. A fella I know who worked for Nissan in the past told me he thought it probably had some trash in the oil gallery leading to the tensioner restricting/blocking oil flow to the tensioner and that he always blew it out with compressed air when he did the timing guide change.(the oil hole behind the tensioner going into the motor block). I didn't know about that trick when I took it apart though. Also it would still seem like the spring in the tensioner should still take up the slack at startup. Maybe I just got a faulty tensioner. I'll probably pull it back apart later this year. I also wanted to say those of you with the 2wd. You don't have to take the oil pan off to swap chain/tensioner. I think I took the front 3 or 4 bolts out on each side and loosened that many more and it will let the pan give enough that you can get the front cover off and on ok. Yeah the little Nissan has saved me a ton of money in the past and I'll just have to fix it....again!

Good Luck,

Brian

Does it do it just at startup? or when you're running? If it's just at startup, you should try the factory oil filters. they hold pressure better over time. If it's when running, you may have an aging oil pump, which is a lot easier to replace than a tensioner. see if you can get your oil pressure checked.

Anyone know how to bolt the engine back up to the mounts after undoing them all? Thx
