This thread is long enough even I do not remember where stuff is.  Because I can edit my own threads at any time, I am going to add a table of contents on my pages.  But not all at once!

 

On this page:

Purchase

Engine inspection

Floor inspection

Roof patch plate

Engine bay tiding up, removal of extra brackets.

Carburettor issues

Test running, auxiliary gas tank.

Engine removal, replacing leaking core plug

Heater removal

Pressure test of cooling system, engine and radiator not in truck.

Start of body work, on lower grill rail

 

 

I bought this truck. MicroMachinery delivered it to me on Saturday April 10, 2011.
Here is a picture of it just after delivery, in the drive way.

Here is a close up of the right door, complete with stuff growing on it.

I spent part of the day cleaning it out, getting rid of old garbage like this, TennisRackets.jpg
Here are more pictures.

Here is the engine.

I took the cam cover off, to find out where number one cylinder was timed, and it looked like this. Pretty clean, a nice surprise.

I did not get an alternator with this truck, but they left the bolts.
AltBolts-1.jpg

I bought this truck mainly for the parts, but I think it might have potential as a runner.
I did a compression test on the engine. All four cylinders showed 145 to 155 PSI, with the throttle closed. The throttle was stuck from the truck sitting. It was last registered in 1991.

After playing with the points, and the timing, I could get the engine to fire, and run briefly by pouring a little gas in to the carb.

you read my post like a woman would, interpreting.... not actually reading.

wait skib loves the cock

Should I do it to myself or get skib to hammer me?

Ever hear that saying about people in glass houses Syncro?

Good news. That looks amazing under the valve cover! I wish I could have kept it, but alas, I couldn't. It went to a good home, and I have no doubts that you'll be able to resurrect this sleeping beauty. :)

Now, some bad news. Here are pictures of the floor, almost good enough for Fred Flintstone.
Right side.
Posted Image
Left side.
Posted Image
The roof has this unique feature, and it has leaked a little on the inside.
Posted Image

The left side of the engine bay had this odd bracket, and wood shelf.
Posted Image
And this bracket by the horns.
Posted Image
I removed them tonight.
Posted Image
There are also two red wires spliced into the ignition coil wiring, that go to a toggle switch located above the hood release handle in the cab, a crude anti theft device.
There is also an ammeter added to the wiring, here is a picture of how it was spliced into the wires.
Posted Image
The bolt without any insulation was just hanging loose between the starter, and oil filter. Other electrical issues on the right side of the engine bay is the voltage regulator mounting.
Posted Image
The voltage regulator is mounted to one of the battery tray support rods. If you look close at the picture, you will notice the ground lug with two black wires just hanging out in space.

I removed the radiator, and when I took the upper radiator hose off, I found this.
Posted Image
Yesterday, I did a pressure test of the cooling system, and I found a leak in one of the core (freeze) plugs in the engine block.

I also pulled the carburetor off, there were only three nuts holding it on the manifold, instead of four. I am sure you all have seen an L-16 engine without a carburetor before, but here is a picture anyway.
Posted Image

And here is a picture for Micromachinery, of the bed. with only a radiator in it. He will remember old leaves, pieces of bamboo, some trash, a piece of concrete, and other crap that was in the bed.

Today, I played around with the carburetor. I sprayed some penetrating oil on the throttle shafts, and was able to get them free to move. Looking into the secondary bore, part of the gasket that goes in between the throttle plate, and main body of the carburetor was in the bore. I found the screws holding the two parts of the carb together were loose. I found a gasket in my gasket collection, and put it in, and tightened up the screws.
Then I got a small gas tank from a riding lawnmower I scrapped last year, and a piece of 1/4 inch hose, and used it to gravity feed the float bowl. Almost immediately, gas started to leak out from under the sight glass. I took the metal piece that holds the sight glass, off the carb, and the glass, and found a crack in the sealing ring. I then took the sealing ring from another old carb i had, and put the carb back together. I probably should have checked it again for leaks, but since I found the obvious reason for the leak, I just put the carb back on the manifold of the truck.
Picture time!
Getting the carburetor off a L-16 engine can be a pain. Here is a picture of a wrench I modified to get the hidden nuts that hold the carb to the manifold.
Posted Image
here is the wrench being used.
Posted Image

Everybody who works on these old cars meeds some of this:
Posted Image
And the tools to cut it,
Posted Image
And a punch to make holes,
Posted Image
So you can do this,
Posted Image
and end up with these.

Hey, that bed cleaned up pretty nice! Bummer about those holes in the floorboards, though :( I didn't know it had gotten that bad. Enjoying the badminton rackets?

I think I may have a special place for the badminton rackets Friday morning. That just happens to be garbage pick up day for me.
I have seen several project threads here about repair of floorboards in many other vehicles. I was not totally surprised. I do have other cabs with better floor boards, but they have major front end damage. I could use the good parts from two trucks to make one good one.
Even with the holey floorboards, I am still happy with the truck. Tomorrow, I may see if the truck will run on the carb, instead of just dumping gas through it. I am in the process of evaluating the engine in the truck. The engine might be the surprise bonus of this truck.

This morning, I took the lawnmower gas tank I have, and hooked it up to the fuel pump on the engine like this.
Posted Image
And then I thought, if I hold the tank above the engine, maybe gas will just run through the fuel pump, and into the carb, like this.
Posted Image

Sure enough, gas started to flow through the fuel pump, and fill the float bowl on the carburetor.

Well, with a full float bowl, and a battery hooked up, lets try to start it. Put the key in, and with one hand holding the choke on, and the other turning the key, it started! But it would die as soon at I let the key go out of the start position. I did this several times. I then hot wired it, by running a wire from the ignition side of the ballast resistor, to the battery positive terminal, and it started, and ran. I then quickly checked the oil pressure. It has decent oil pressure!

It starts, and runs! I reset the points, by eye. I set the timing by getting it close, and then advancing the distributer slightly, again by eye. The carb was just cleaned up a little, and the throttle shafts unstuck. No adjustment on the carb, just put it on.

Now, I need to pull the engine, and replace the core (freeze) plugs, and see if it will hold water. Next, get the clutch working, and at least the emergency brake, so I do not have to depend on blocks, or chaining it to a tractor to stop it from moving.

It is well on its way to becoming an Automobile again. a vehicle or mechanism capable of moving itself.

They say it is going to rain pretty steady, for a few days. So I moved the new 521 in to the garage.

The plastic tank I used is clean inside. I used a new piece of hose to connect it to the fuel pump. Pretty much any dirt in the carb will be from another source.
I have not even looked inside the gas tank on this truck yet. I will probably drop it out of the truck, to clean it out.
When I hook up the gas tank for the first time, on most of the vehicles I work on, I use a marine fuel filter that has a filter element about the size of a Ford FL1-A oil filter, sitting on top of a sediment bowl.

I found the pictures I took today, When I download the pictures from my camera, before I down load them to the computer, I rename them. That way, the pictures do not just have a meaningless number.
I removed the seats today, and wire brushed the floor. I also removed the seat belts, and an old fire extinguisher mount.

After cleaning.

Here is what the front of the floor looks like.

I also pulled the engine today. I wanted to pull the engine, to clean it, and the engine bay. Posted Image
Posted Image

And here is a typical engine bay.
Posted Image

And in an area where I would expect a lot of rust, on the battery tray, it is not bad.

I started today, doing some clean up, and organizing. If I cannot put bolts back in the part, I put them in a bag, and label the bag. The bag then goes into a parts box.
Posted Image
After doing that, I lifted the engine and then slid my parts washer under the engine, and cleaned the engine a little more.
Posted Image
Here is another reason I pulled the engine. I had to replace this plug in the block. you may recall, at the beginning of this thread I made mention of the block having a bad core (freeze) plug. Here is the new plug in the block, I actually put it in last night.
Posted Image
Here is the plugs I used.
Posted Image
Because I had one bad plug, I needed to check them all. Even the one in the back, under the flywheel. Before removing the flywheel, I put the engine at TDC, number 1. (and 4).
Posted Image
And after putting the engine there, I put a mark on the flywheel.
Posted Image
Then I removed the flywheel. This how I held the flywheel from turning when I loosened the bolts.
Posted Image
With the flywheel off, I did some more cleaning.

Then I set up the engine to pressure test the cooling system. I wanted to do the entire cooling system, so I needed to remove the heater from the truck.
The nuts on the studs for the heater were rusty. Like this.
Posted Image
The first step is to spray some penetrating on the studs, and nuts. You really do not need a picture of that, do you? Then you wait. Let the oil penetrate. It is much easier to wait, than to repair broken bolts. After waiting a while, try to loosen the bolt, or nut. If the nut goes a few turns, and then starts to get harder to turn, STOP! Spray some penetrating oil behind the nut, and then tighten it up again, but not tight.
This is a wire wheel you can get at Home Depot.
Posted Image
Put it in a drill.
Posted Image
and use it to clean the rust and crud off the bolts you are trying to remove.
Posted Image

After removing the heater, I pushed the engine on the stand under a rafter, and used pieces of twine to hang the radiator in front of the engine, and the heater behind the engine.
Posted Image
Here is a picture of the pressure test pump hooked up to the radiator that came with the truck.
Posted Image
If you look close, you can see a problem with the radiator, in the last picture. Here is a better picture, of a bad radiator.
Posted Image
Conveniently, I just happened to have spare radiator.
Posted Image.
I took off the radiator that came with the truck, and hung the spare radiator, and tested again.
I found the lower radiator hose was leaking. I had a spare on of those, and changed it. Then I found a leak in the short heater hose, and changed it with another spare hose I had.
Finally, I got the cooling system to hold pressure.
Posted Image
This was after sitting for a few minutes. Success!

Before hanging the heater, I tested the motor on it.
Posted Image
It is running in the picture. Really it is.
This is the picture of the battery hooked up to the heater motor.
Posted Image

Today, I also went and got some parts for the engine. I got a hose for the PCV system, the hose was gone on this engine. Here is the new hose I got. I got it from Tonkin Nissan, in Wilsonville.
Posted Image
While there, I also got an oil filter.
Posted Image
and then I drove up the road to Schuck's I mean O'Reilly auto parts, and got some Spark plugs,
Posted Image

So, that is enough for today. Maybe more tomorrow.

Today, I did some more work on the engine. I have a Mitsubishi 50 amp internal regulated alternator I put on the engine, but I need a longer belt to drive it. I also put a matchbox distributer on it. the distributer came from a 1980 200SX, with a NAPS-Z20-E engine, and I did not get the pedestal or the plate that holds it in place. I did some wiring on the truck, to accommodate the distributer.

I also did some work on the front end. I removed the front bumper, the lower valence panel, and the trim around the headlights, and grill.
