WHEN INSTALING THE DISTRIBUTOR THE ROTARY BUTTON HAS TO BE POINTING AT THE NUMBER 1 CYLINDER AT TDC
Yes
No compression could mean a blown head gasket, cracked head or cylinder.
yes it does need to be facing towards it
No. When the timing mark is at tdc, #'s 1 & 6 are both up. One is up for compression, the other is up for exhaust.
Check the Piston Ring.
Remove number one spark plug and squirt some motor oil into the cylinder. Now do another compression test. If the compression goes up considerably in number one cylinder you probably have bad/worn or cracked piston rings. If the compression doesn't change much you probably have burned or bent valves.
Remove the spark plug for each cylinder and screw a compression tester in it's place. Crank the engine around a few times and record the highest number achieved.
Number one cylinder is located driver's side front of engine. With the # 1 piston at TDC on the compression stroke, the rotor will be pointing at #1 plug on cap.Number one cylinder is located driver's side front of engine.

You need to check the compression in #2 and #4 cylinders and compare them. A good cylinder should have at least 140 to 150 LBS. of compression. If #2 is 20 LBS. lower or even lower then that it means you have valve problem on #2 cylinder. You may even have a rocker arm off or a valve spring broken on that cylinder. PULL VALVE COVER AND CHECK. Check push rods on #2 cylinder too. They could be bent. HOPE I HELPED
check the compression
check your compression on #4 cyl
Run a compression test on #2 cylinder. You either have a burnt valve or cracked head.
