The 2000 Mustang V6 Compression is: 9.36:1 The 200 Mustang V8 Compression is: 9.0:1
i'd like to see 130-140 psi. gotta have 90 to fire.
there is no hard fast rule here. but typically with the cap off and number one cylinder at TDC on compression stroke. the rotor will point at number one cylinder on the engine.
Oil burning or loss of compression on any one cylinder. It may also be missing on one cylinder. A compression test will verify this.
a broken valve spring could be the cause, or a lifter. Start by checking the compression for the number 8 cylinder, then remove the valve cover to inspect the rockers and lifters.
The lowest reading cylinder should not be less than 70% of the highest and no cylinder reading should be less than 689 kPa (100 psi). Perform compression test with engine at normal operating temperature, spark plugs removed and throttle wide open
Number one cylinder for v8 and v6 is always the front cylinder on the head that sticks further out on the front of the engine. The heads are offset on all v6 and v8 engines.
120-150 psi
18436572.............#1 is front cylinder on drivers side.
If it is a V8 it is 65FT.- LBS.
The 293 or 4.8 L is a V8
you will need V8 motor mounts and a bigger radiator.
