that's very low compression, I would take it into a shop....could be blown HG or many other things.
Should be 110 PSI
I have a 2005 and compression should be close to 120 psi. Normally a good engine will have compression between 115 and 130 psi but a leak down test should be performed also to know the full condition of a cylinder.
then youre running about 8.5:1 compression
Cylinders compression pressure Sentra 1.8 : 192 psi
HI, Compression should be 128 to 156 psi, with no more than 14 psi. difference between cylinders.
100-125 psi
A good 454 will have at least 150 PSI per cylinder.
The ratio is 9.5.1 in the 350 vortec. Doing a compression test you should not have any below 100 psi and all should be similar to each other.
120-150 psi
When it was new it had 150 PSI. per cylinder
150-160 PSI
Tire psi? Engine compression psi? Radiator cap psi? Engine oil pressure psi?
