What should I do to correct low compression? Replace rings?. replace head gasket? Anything else?

 

check the valves for holding pressure

 

I added oil to the cylinders and the compression did NOT change, DOES that indicate BAD VALVES?

 

possible

 

any suggestion based on data provided?

 

u already know the prob fix it

 

Would you say is the valves, not the piston rings? If I do not have to buy rings that will be a big saving for me. If I had money to spare I would have gone to the dealer's service department.

 

if the rings were bad the trans fluid would have brought up the compression U said it did not.

 

thanks for the advise. just trying to do the correct thing at the lowest cost....

 

I grinded the valves with coarse grout and rechecked the compression. the compression went up to140 from 70, except on #1 and #3, which stayed low(110). Next I resurfaced the heads, regrinded the valves again and replaced the head-gaskets, now I am getting lower pressures than before resurfacing. Rechecked the compression with oil in cylinders but did not improve noticeable Could it be that I did not use fine grout?

PLEASE HELP
