I was experiencing minor blue smoke out the exhaust and excessive blowby into the air filter housing on my otherwise excellent 300K mileage car. Had rings and valve seals replaced. Only honed the cylinder walls, did not bore them out. Used original pistons and valves. Now blow by problem is worse. Have driven almost 2000 miles, and oil is dripping out the bottom of the air filter housing. I'm using a quart about every 700 miles. The car runs fine, and has much better power than before the overhaul.

Should I do a leak down test? Before the overhaul, a leak down test was judged OK, but not really that bad.

I would really like to know how to troubleshoot this problem. I expected the new rings to fix it. Any help would be much appreciated.
