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.
