ive got a D15B7 bottom end and block with a D16A6 head on it and it SMOKES like hell. i ran a compression check on each cylinder. i got 140 to 150 lbs across it. ive went throught 2 sets of spark plugs in 10 miles. theyre turnin black right off the bat. anybody know what might be wrong?

any help would be appreciated guys. this is my daily driver. my family car. i need to get it back running

 

Valve stem seals, piston rings to name a few

 

i thought maybe the rings to but i did a compression check and it was between 140-150 lbs. im not sure if the valve seals are any good though.

 

Do a wet test as well. Mine all check out at 145/150 all across, but add a teaspoon of oil and the numbers shoot up into the 160's

 

IM LOST ON WHAT TO DO NOW. ive got good compression so im guessing its something in the head makin it smoke.
