    Super looking Skylark @Daniel87 !  Hope you can cure those ills without much effort.  The loss of compression is a major issue though.  

     

    One thing to be aware of is that the 215 alumimum engine is not like previous Buick V8's. The older V8's are affectionately known as "nailheads".  Your engine is the earliest of the later V8's with a distributor and oil pump up front in the timing chain cover.  And since the timing chain cover is aluminum while the manufacturer used steel bolts, in many cases you will find bolts are hopelessly stuck where they may pass through to the water passages of the coolant system.  Be careful in disassembly.  Be careful with heat if a bolt is stuck.  Aluminum will melt at a much lower temperature than steel.  And good luck with the compression loss. 

     

    I would like to hear more about that compression loss diagnosis though. 

    Hi John, thank you for this advice, this is really helpful! I’m most worried about the compression loss. A mechanic brought the issue up to me after using a leak detector fluid kit. He gave me an estimate of ~$9k to take the engine apart and find out what’s wrong. I couldn’t afford that and would like to do as much of the work myself over time if I can, although I’m pretty green. To start I purchased an engine compression tester to see which cylinders have compression loss. I’m hoping maybe the test the mechanic performed represented a leak in the exhaust or intake manifold and the fix is simpler. But I won’t know until further testing I suppose! 🙂

  3. Hello! My name is Daniel, I live in Los Angeles and recently purchased a '62 Skylark that has spent its entire life in SoCal. This is my first Buick and I am in love! Under the hood is a 215 aluminum V8 with a 4 barrel carb. My projects for the car include:

    • Investigate engine compression loss issue
    • New exhaust manifold, y pack, and muffler
    • Replace parking pawl - seems to be slipping. 

    If anyone has any suggestions for me about these things or any advice, I'm all ears! I'm excited to be here.
