So my 95 ST had a rod knock and was burning oil so I figured I'd do a full rebuild. I replaced the pistons, rod and main bearings, and new rings. The the engine was over-bored to .50mm and the crank to .25 over-bore, which called for bigger pistons and bearings. I followed Smaay's rebuild thread. Everything looked good. So once the rebuild was done I cranked the motor and it turned on very quickly. And for the first 700 miles I noticed the oil level wasn't changing so I thought it wasn't burning any more oil. But then when it was at 1,200 I checked the dipstick and it was missing about a quart. I've changed the pcv valve and its still burning oil. I opened up the intake manifold cover and its full of oil. I don't know what else to do. I'm thinking Im gonna have to throw away a lot of money and just get rid of this motor and get a used one that will hopefully not burn any oil. Anyone have any suggestions as to what I should do? Car runs perfectly fine, its just that it burns oil. I did a compression test and it reads a little over 160 on all cylinders. No leak down test has been done yet.

Pull the breather hose off while the engine is running, with the one end still attached to the valve cover. Place your thumb over the open end of the hose and blip the throttle. Is it pulling any kind of vacuum?
