    • I isolated the fault now!   A compression test showed no compression what's so ever on CYL 2.  Even with my finger over the port I could feel no signs of compression.    Pulled the head and found that CYL 2 had the intake valve stuck open.  The piston was soaked compared to the other two as well.  I haven't been running any fuel treatment in the car for a number of year now.  Looks like that was a mistake and has caused excessive carbon build up on the valve stem causing it to stick.  I use Co-op diesel here on Vancouver Island.  A few years back they seemed to change the formula and I stopped getting fouling injectors.     Now the question I have to ask myself...  Rebuild or replace the engine.  Hmm.  I need the car back in service, so thinking about replacing it with a working used one.  Then keep this one as a rebuild core. 
    • Well, pulled the engine today and started breaking it down.   Then I realized it's not a mechanical timing issue.  I noticed a timing mark on the flywheel and a pulled the valve cover.  Lined up the TDC mark and the cam shaft gar mark also looks good.  No timing slip.    Attaching photos...   Now I'm wondering if there is a way to do a compression test before I break it down more.  
    • Just got it back from Smart last night.    They diagnosed it as "internal engine fault".  They indicate that means it's not a bolded on accessory or sensor but something internal to the engine it's self.  Looks like I'm pulling the engine this weekend.  Checking the timing alignment will be my first goal. 
    • Thanks for the feedback Stick!   I'm not sold on that idea yet.  Engine was rebuilt just over 40K ago.  Cords, a very reputable shop locally, did the valves/guides and decked the head for me.    Haven't been able to isolate the issue so Smart is going to take a stab at it Wed.
