The only thing that didn't put up a
fight was the crankshaft sprocket, which should have according to the
manual, but it slid right off.





Replace the crankshaft pulley, it shouldn't slide off. Whether it's a Datsun, Nissan, Honda, Acura It should be a snug fit. A loose fit is a sign of pending issues.
Same for camshaft. Worked on an Accord sounding crappy, turned out to be a worn camgear. It literally fell off the cam using 2 fingers.

Yes. Seeing as I had to take the whole timing case apart it was decided to replace the timing chain and sprockets too, not to mention all the gaskets. (The sump gasket had actually been fitted with RTV sealant which it apparently doesn't need in such great amounts). I purchased the whole timing chain kit almost a year ago, but never got around to taking it apart until now.

The new crankshaft sprocket did put up a good fight when it went back on, so no issues there.
As the truck also has a new cylinder head with all new valve guides it shouldn't burn oil anymore as it did previously. Some work was also done to repair a blowing exhaust pipe, so Red Thunder isn't half as noisy as she used to be. xD

Also, here's a video of my truck coming back from Portland, OR through the Seattle area.

Watching that last video going through Seattle takes me back to my old everyday commute. Blech!! I started having an anxiety attack all over again. My knee jerk reaction was to yell at someone. Ahhh. Glad I moved away from there. Beautiful place but the traffic is the worst anywhere.

Another update... got the truck out of the garage and took it for a short drive yesterday. It's not 100%, but it does go. I'm not sure what the problem is, it idles really high when it's cold and when warmed up it idles great, but runs rough - sounding like a Ford F150 xD

I guess my truck's just trying to earn her name back after I fixed the blowing exhaust. Dad informed me it may be my valves and ignition timing - we did the valve clearances on the cold engine before we started it, but then we have to recheck them after it's had a good run and do the ignition timing, not to mention retorque the cylinder head bolts once it's had a few runs.

Put a Weber carb on it. You'll be soooo much happier!!

I probably will swap the stock carb for a Weber, but the stock one will suffice for now. Already put over $1000 into this truck and it hasn't even got the bodywork repairs or respray it deserves yet!

It did idle FAR too fast before - the sort of idle that if you put it in gear you'd probably shoot off at 0-60 in five seconds. This was actually a vaccuum leak due to two missing nuts. They were put back on before I took it for a fresh tank of gasoline when I made the previous post. Should be checking the hot valve clearances and ignition timing this weekend if the rain holds off.

Just a few more images... took the truck on a road trip two weeks ago after having fixed the valve clearances and retightening the cylinder head bolts. Here's one... snowed in in Nanaimo!

Then another picture, this one's at the Tantalus lookout, on the way to Vancouver from Whistler. Next few things planned for this truck are welding up the rust gashes in the bottom and sides of the bed, and hopefully a new paint job, exhaust pipe and muffler.

Got some news to share... some of it isn't very pretty - but at least I still have the truck.

Red Thunder has been popping and banging about and taking me to-and-fro. I was planning on taking it to Seattle (for a third time) but sadly she's in no condition to do so. Lately it has been running weak and last week I took her up to Nanaimo for the day. Lots of backfiring and some particularly loud ones really had me thinking about it. I parked the truck and left it to cool down, hoping it would do better on the return trip. Returning home it wasn't much better, put the truck in neutral to minimize the backfiring at every red light I hit. Just south of Duncan some kids decided to pull out straight in front of me, needing me to jam on the brakes - hard. Luckily I didn't hit them. Again I hit another red light about ten kms south of Duncan (Cobble Hill) and put the truck in neutral, and it cut out. Long story short I requested a tow from CAA back home.

I'm thinking carburetor issues now - so not only does my truck need a new exhaust pipe (custom fabricated because of the lack of a catalytic converter) muffler and tail pipe - but also needs a new carburetor. Right now of course I can't afford that sort of money ($532 for the exhaust, muffler and tail pipes, and nye-on $400 for a weber carb). So in short, my truck will be reserved for local shopping runs only (it only cuts out when the engine is at temperature, cold it will still idle) until the middle of September when I will cancel the insurance (cost $30). Hopefully I can request a local high school to do the carburetor replacement for me, and then look at having the exhaust pipe, muffler and tail pipe replaced. Another problem though is all of the BC Schools are still on strike, meaning there might not be any school for a while.

Jeez...

Hate to here that. Hopefully you can get a school to do the carb, save some money there. She just needs alittle freshening up and she'll be good as new.
