Who wants to tell him it is time to get help tearing it apart if his compression test is accurate?
Since youre new to this without being too rough here's a potential and common scenario.
Driver is out romping on his bad pony, its going great car's never run so badA..
stomp the pedal one more time and wham, bam power train batman what was that.... and now it wont start;
one common answer is the timing chain jumped a spocket tooth or two, this throws the cam degreeing/timing off by an unknown amount,
the cam now makes the valves out of sequence with the cylinder rotation, and most likely the cylinders slammed into the valves
bending them, thus no compression and the cause of the issues youre hunting... however I could be wrong
and to be fair this can just happen without cause with an old timing chain and worn sprocket gears
So it went down 8 years ago? Leakdown will answer your rings, which may not be sealing due to time sitting for allot of reasons. Compression should never be zero, you need to be sure the plug fitting is in tight or youll get a false low. All signs point to the likely hood cam/timing being out of sync. Id pull the timing chain cover, first then proceed to pulling weakest test side head.... others posting to you have deep knowledge follow their lead....
Do you have a garage or work space? 8 years, unknown failure, track record of gasket failures.. Take your time, tear it down and see what you have. Then you can reassemble (or machine shop) and drive with confidence. Otherwise you'll always be wondering what's next... if you start now you could be back on road in no time. Do you have a budget for fixing it?
