1994 Toyota Corolla Loosing oil

I have a 94 Toyota Corolla with a 1.8 engine. I bought it with spun rod bearings, I had the crank ground 30 and the mains 10, the machine shop said the cylinders were fine with standard bore, had a valve job done. After 600 miles it is still using oil, about 4 quarts to 600 miles. It smokes a little but it seams to be blowing it out the tail pipe. I've done a compression test both dry and wet, between 190 and 210 psi. I did a leak down test, cylinders 1 and 2 had 15 % leakage while 3 and 4 had 5 %. I had found oil up in the intake and I removed the oil filler cap while it was running and oil was blowing out like I had a lot of blow by. What else could be causing the pressure? I put a new oil pump in it, could it be putting out to much pressure? The pistons and plugs are covered with oil.
