This turned up at a local classic car get together yesterday evening, definitely from the same era as the Chieftain.  1947 in this case I believe.

I used to just look straight past cars that were this old, but more and more over the last few years I've been more drawn to them.

Particularly as that's a $80k vehicle...

saw the gta running

what are the two missing buttons at the bottom of the binnacle?

and the cheef - the having no park thing and just leaving it in gear was that a hydramatic thing or a thing of the time?

Blanks, they have the securing screws behind them.

The parking in R was a Hydra-Matic thing; they figured why add extra positions? Parking a manual car in reverse was fairly common practice to save stretching the parking brake cables back in the day.

In a modern vehicle P does the same thing as this does, it engages two years at once and locks the gearbox up that way.

Been driving about a whole bunch.

Went continue tidy up at mother in law's lot. Takes forever, glad I had spare belts for the mower. That's genuine mower-shite too, it's British Leyland levels of rusty.

Headed home. Warm air, window down radio on, engine humming away up the highway.

Got bugs all spattered up the glass. Can't say it's a trailer queen.

Hit the highway at the weekend, cruising Louisiana Highway One.

Hot day car was running pretty well but on the way out the horn got stuck on, so I pulled the wire off and had a look when I got home.

Thankfully it all still comes apart with relative ease.

Hammered the bearing out thinking my wiring had failed, but that was all in good condition. Turns out the rubber ring that holds the horn push off had gone soft, and the hot weather was just compounding that. The weight of the push was making the connection.

Had a little bit of light once the day cooled off, so I decided to look at the brightwork.

Gentle application of abrasives saw an improvement, which I'll need to continue with. Dremel doesn't like the work though, it overheated.

A hot and sweaty afternoon gave rise to some troubleshooting.

Engine cold, sat 2 days without running.

Compression test (dry, psi).

115

124

95

113

122

116

105

120

Compression test (wet, psi)

120 (+4.3%)

128 (+3.2%)

128 (+34.7%)

115 (+1.7%)

125 (+2.4%)

115 (-0.8%)

123 (+17.1%)

120 (+0.0%)

So, cyl 3 is a touch low... and comes up real nice when oiled down, cyl 7 is a bit marginal and again comes up nicely when oiled.

Result? Yea, the rings are tired. Dry, none of the cylinders leaked down over 5 minutes. All took about 5 compression strokes to come up to peak pressure.

Do I want to do anything about it?

Suggestion is check the rings.

I found my spring compressor, also pulling the head and pan off is fairly straightforward though I don't have a plan gasket spare. I might have to order one and then lift it off.

I think I might just go the chemical route first, dump some glop into the low bores, see if they come round.

I washed the car because my neighbor had a couple truckloads of dirt delivered, which they regraded their yard with using a bulldozer so everything got covered in dust.

Naturally ten minutes after I finish drying it, the rain starts.

Still, milkshakes with my sweetheart made up for it.

There's so much to do round here...

Little bit of diagnosis this morning.

20220605_134737.thumb.jpg.59db4872a09a5118cb54f2c9c8e747fc.jpg

Cylinder 7 has come back around and is now a healthy 125psi.

Cylinder 3 is still low at 95; brought the engine round just past TDC on compression on #3 and poured the cylinder full of Berryman. It promptly all drained out until it got to the top of the cylinder. That stayed there, so leaky valve.  

I can pull the head off and lap the valves in again, that's fairly easy.

Polished the wheel trim logos- the red lacquer was looking dull, I had forgotten to do it when I did the rest of the car.

Now, relaxing on the front porch swing with an iced tea. Mais cher, welcome to de South, yeh.

The first of a few things for the car arrived in the mail today.

20220613_111059.thumb.jpg.c513880fff51172539e85bfc0957ec1f.jpg

The rear wheel trims were painted by previous keeper unknown, and were looking a little tired.

20220613_111530.thumb.jpg.e4af32666aa500a10518582fadc63af9.jpg

I started to clean the paint off, and found the original red lacquer, now a faded pale brown, underneath. This confirmed my theory they were originally done like this to look jeweled.

20220613_112612.thumb.jpg.ff6076588146f4e1b8a8807353135cbb.jpg

The metal was in really nice shape underneath, having been mostly protected by the old lacquer.

20220613_122256.thumb.jpg.e515eb27eec04a7519e3e9949290431a.jpg

Masked them up and painted with new red lacquer, same stuff as I put on the fronts years ago.

Much better! They look nice now.

Shame that's all you see of them. I'll cut and polish them in a few weeks when the paint is fully hardened.
