Anyone know of any problems with the 2.0 16v Ecotec engine. piston number 1 ?
my last engine had compressions (bar)
11, 18.5, 18.5, 18.5 (pistons 1,2,3,4)
2,3,&4 are eceptionally high?? whilst 1 being just a little bit low, the engine ran like a dog and I changed it
the new engine has
14, 16.5, 16.5, 16.5
So not as bad (and it runs fine) but still there is a noticeably similar pattern here.
I am recon..ing the old engine so I won't really mind if the new one goes the same way as the old one

Ignore the compression pressures, the variance between cylinders should be no more than 10%
A cylinder loss/leakage test* will show where the pressure is going.
* Professional Equipment required to do this test..
