How much longer can i run her :( (compression tested)

Just got done doing a compression test and wow am i having a bad night. Here are the results.

Cylinder 1: 135 psi
Cylinder 2: 135 psi
Cylinder 3: 154 psi
Cylinder 4: 150 psi
Cylinder 5: 140 psi
Cylinder 6: 137 psi
Cylinder 7: 75 psi
Cylinder 8: 140 psi


How much longer do you guys think she has left to live?
Im not in a position for an engine swap right now so id like to continue drivibg her 10 miles to work and back everyday. Till im ready for a swap.

Its a 305 so atleast ill be doing an upgrade :/

Only performance loss atm is a constant miss while just barely accelerating.

Thanks for reading
Inputs welcome.

Re: How much longer can i run her :( (compression tested)

Well there really is no good answer to this question.. If your gonna put a different motor in and dont plan on rebuilding this one then.. I would say drive it till it dies. As long as you dont beat the **** out of it I would imagine you could get some time from it yet. Too many variables to give an actual time frame though. good luck.

Since you know it is bad, just baby it, I am sure you will make it for a while.
