Compression test #s- need advice

[tonysmach]

Did my first ever dry compression test today. I borrowed and old compression tester from a friend. Here are the numbers:

cyl 6 150 cyl 5 156
cyl 4 135 cyl 3 151
cyl 2 150 cyl 1 135

I am losing radiator fluid from the passenger side of the engine. I can see it drip from underneath. Oil looks good. Do I have a blown head gasket? Should I go rent a radiator pressure tester and do that? Thanks in advance for your thoughts.

Pressurizing the coolant system will push it out if you want to see exactly were it's coming from but you can pretty much take it to the bank, you have some type of head gasket failure.

Is there any chance it may be heater core? or are the psi on cyl 1 & 4 too low?

150S across the board give or take a pound. stock motor with 80k on it. Do a leak down on it and check the percentages off loss.

Could be heater core or hoses You will have to do more testing to find out.
