I have oil pumps from a 1951 and a 1953 263 engine. They appear to be identical. When I pull the cotter pin to release the strainer and tube from the pumps, the end of the tube has a recess that looks like it should have an O-ring or some similar seal on it, but neither pump has a seal. This...

On my '51 Special, after dropping in a replacement engine and transmission, I noticed when hooking up the clutch to clutch pedal linkage that what the shop manual calls the "clutch equalizer" seems to have parts missing.(see diagram from manual below). The bearing on the end is missing...

I'm putting a 263 with clutch and transmission attached into my '51 Special. When I took the old engine and transmission out, I unbolted the driveshaft housing from the transmission, and unbolted the transmission from the U-shaped transmission thrust plate bracket which I left in the car...

I've just finished rebuilding a 1953 263 and will drop it into my '51 Special tomorrow. I have 1951 and 1953 carbs. Is there any notable difference? If not, I'll put the '51 carb on the '53 engine because I rebuilt it awhile back. Thx, Dave

I tore down a 1953 263 to see if it needed anything before I drop it into my 1951 Special. Everything was fine, except two cylinders had broken compression rings. My calipers aren't precision enough to measure out to 3 decimal places and I'm not so sure about it's accuracy of the last digit...

After doing a compression check on a 1953 263 engine I bought, (Compression was good - 100 to 125 pounds), I want to pull the head to be sure there is nothing bad going on inside, like pinhole coolant leaks, etc. I've pulled a lot of heads off various engines over the years and never found a...

I have a 1953 263 that I bought recently. When I opened the coolant block drain petcock, nothing came out. I removed the petcock and stick a screwdriver in the hole and it only went in about 1/2 inch, with black stuff in there that I chiseled at that was hard as a rock and got the screwdriver...

On a 1953 263 that I bought used, the shop manual and the reference section above say on the road valve lash should be at .015, and can be adjusted to between .017 to not quite .018 after a short warm up in the garage, and this will give .015 when warmed up on the road. Since the slightly...

I'm about to tear open a 1953 Straight 8 263 from a Special. I have a Felpro engine gasket kit ordered, but from the photo, I don't think it includes the rope seal for the rear of the crank, or the timing cover seal for the front of the crank. Rock Auto lists them as out of stock; and I...

I had the input shaft bearing go bad on my '51 Special 3-speed. I got another transmission from a junk yard and the input shaft bearing was also bad. A friend who is a mechanic went through one of these transmissions, replacing the input shaft bearing and also going over everything else...

My 1951 Special has a 1948 Sonomatic radio which is nearly the same as a 1951 radio. When I got the car, I had to cobble in a replacement power transformer that was not meant to be there, ( I took a transformer from a 240 volt to 5 volt Dc power supply and drove the transformer backwards...

I bought a 1953 straight 8 on Craigslist that supposedly is a good runner, but before putting it in my 1951 Special, I am going to pull the head and pan and check bearing clearance, valves, rings, etc. I have a heavy duty engine stand that I've had motors as big as a 472 Cadillac V8 on, so it...

Hi Everybody, I'm new to the forum, but I've had my 51 Buick Special Deluxe with manual transmission for about 30 years, but it hasn't been on the road for about 20 years because last time out it spun a rod bearing. Then other things in life got in the way so it sat still. Now I have time to...
