- 1978, 1500 Midget. Blown head gasket last week. (between #3 and#4, not leaking into either water jacket or oil ways) Drove home 4 miles on 2 cylinders, with 2 "lazy" cylinders, firing but no power. R

- A "leak-down" test will tell you exactly where and how much potential compression is escaping. WFO Herb

- You can put about a tablespoon of oil in #3 and see if the compression goes up. If so, it's probably a burnt valve (the oil helps the rings seal). The leakdown test is conclusive though. Chris Kottin

- When I said that the comp test measure were taken "wet" I meant with oil added to the cylinders. I was trying to eliminate cylinder wear, so I gues the lower comp. on #3 is due to the valve? What I
