90K approx..

Also, codes were P0343 and P0367.

I had also checked spark on #1 - its there, did not check the others. Just strange that #2 & #4 cylinders haevb no pressure & 1 & 3 appear ok.

any new ideas here? Tying to DIY this before taking to a $hop.. I'm very competent at old Small block Chevy mechanical stuff, not that familiar with the modern ECM engines.


thanks

Michael

P0367 is the exhaust equivalent of P0343, so the electrical testing is the same.

The VVT system changes the timing of the valve operation, and not the actual operation, so I think you should still get compression in all four cylinders.

My next steps would be to check the circuits for voltage (Posts 6&8) and then do a cylinder leak-down test to see why there is no compression on 2 and 4.

IT'S GONNA NEED A MOTOR.....or cylinder head& timing chains...probably cheeper to put a motor in it and probably better too. no compresion is, holes in pistons,valves bent, valves hung open..possiably timing chains broken, jumped timing,it's a mess. I would put a compleate engine in it.rather than trying to fix it unless you have a wadd of$$$ and plenty of tyme.( if it were mine I would then after driving with new motor I would tear appart the old motor and play with it....good luck, dont be skeered of used motor,just try to get a fairly low millage unit.
