Looking for any advice I can get regarding a 1972 1.7 w 48k on the motor
It starts fine when its cold but once it has ran for 5-7 minutes and driven it starts blowing a lot of blue smoke. So much so that there are drop of oil coming off of the tailpipe. Have not checked compression yet -hope to tonight |

Sorry for the dumb question, but asking to learn: How could blue oil smoke be valves? Wouldn't it have to be rings (or scarred cylinders)?
Compression and leak down test will surely reveal some answers, no question there. |

Back in the day when I was raising a family, we had a Dodge Caravan. It was of that era where they had valve guide problems. It would run clean, until you let it idle. Which was a nightmare at stoplights... It poofed a batman style smoke screen on takeoff. (IMG:style_emoticons/default/biggrin.gif) |
