1989 Jeep Wrangler 4 cyl Four Wheel Drive Manual 190k miles

Looking to buy a used engine, 2.5L
the cylinder pressure runs around 110-115 per cylinder. The motor has 190k
$125
are those good pressure numbers?

Thank you RICK

If they are all with in 5psi of each other then that acceptable, but they are kinda weak.

It will probably run, but it will probably feel underpowered and don't be surprised if it burns oil.
