When it was put back together 3 seasons ago
200 psi across the board todays compression test
1- 179 2-180
3- 200 4-200
5- 71 6-178
7- 175 8-175

It blew the dip stick out on the first pass last day out, I think I might have a ring seal problem How much power am I losing here??

It ran a new best last pass of the day I think it still has a little left

 

Yeah I'd definitely say you've gat a bad ring seal. That sucks man.

 

Its schedule to come apart this winter anyways

 

ok, that's cool. Are you doing all seals and bearings? Or pistons and more?

 

Rings, coated bearing, anti friction coating on pistons ,ceramic coat piston tops and chambers.

 

is there a chart saying what your compression ratio equals for your compression numbers???

 

I don't know but 200 down to 71 that cylinder can't be doing much. Let alone all the others that were low, and the last pass it still ran a 9.88

 

Pretty stout numbers on 7 cylinders

 

Maybe the saying is true, "They run their hardest right before they blow up".

 

I guess that would be true with all the other cylinders that were low would about equal one dead hole.
