Compression test results

[dom14]

Hi Guys,

I did a compression test on my RB30 Patrol today.

These are the readings

6 ---> 180
5 ---> 175
4 ---> 175
3 ---> 175
2 ---> 165 oil squirted 190
1 ---> 190


I warmed up the engine before the compression test & opened the throttle wide.

My concern is the number 2 producing low compression than the rest and jumping to 190 with an oil squirt into the bore, indicates worn rings?!! Or can it be something else(head gasket on it's way?)?

Is it time for a new head gasket and head reconditioning?
Or can I hold onto it bit longer?

Thanx in advance for any tips/advice guys.
