As I posted above, head gasket leak. When doing the reinstall use a FelPro or Victor gasket only and follow this procedure to the letter. Both the head and block must be completely oil and film fre, wipe down several times with acetone.

SOHC head torquing procedure

Initial dry bolt torque in sequence to 48ft-lb following the torquing pattern in stages to 20ft-lb, 30ft-lb, and final 48ft-lb. This establishes the proper clamp load on the gasket.

This is followed by removal in about 1/4 turn in sequence until loose.

Bolts washers, threads and bolt heads are oiled with clean engine oil and reinstalled finger tight.

Torqued in sequence to 22 ft-lb then 33ft-lb and then additional 90 degree turn.

The 90 degrees is important so do not guess at the 90 degrees. You can eyeball it and use a 1/2 drive breaker bar and make the 90 degree turn in a single smooth motion.

If this is not followed the new gasket will end up leaking.

NOTE: oil with clean engine oil and oiled but not dripping.
