So my 355 rebuild has about 1000 miles on it and it is going through oil like crazy. It does not burn oil that you can notice out the tail pipe. Had it out yesterday, drove 158 miles and it is down almost a quart of oil. I am running Bard Penn 20W 50. Are the rings still seating? I have noticed oil in the PCV hose and there seems to be a lot of blow by. Any thoughts on what might be going on?
