https://www.youtube.com/watch?v=Ib4VMyWAwl8 Got Matt's car running this weekend after a few years down. 123 ignition installed and timed. Valves adjusted. Car is a 1.7 with stock injection. Its blowing prodigious amounts of white smoke when the engine is under load. I did not check compression. Matt assumes a vacuum leak, which is certainly possible. Curious notes: all the valves were tight EXCEPT the valves for cylinder 3, which were in spec. Okay brain trust. What'ca got? Zach |

I may have been the last one that helped Matt with his car before you Zach. That was several years ago.
Agree with checking on the age of the gas. Treat existing gas with Star-Tron, fill up with fresh gas and bang a can of Sea Foam in there as well. Aside from the smoke, did it run well? If so, I'd run it a little and see if things clear up before digging too deep. Let me know if you guys need a hand with anything. |

For the life of me I can't think of a reason why all the valves BUT the valves on Cyl3 would be tight. In all my experience, its the other way around. The valves on CYL 1, 2, 4 were tight enough that I could not get a feeler gauge in there with the engine cold. Cyl 3 was perfect. It was like someone just did a valve adjustment on that cylinder. I wish I had thought to do a compression check. Zach |

Matt mentioned that it had been a long time since his valves were adjusted, but we didn't have time to get to it. |
