The bad news is that they each read about 125, while the FSM says compression should be between 170 and 190. So..... Wrote: This points to what exactly? Head gasket? I'm attaching a pic of the spark plugs I just put in two days ago - is it normal for them to be this black after driving maybe 10 miles? Thanks!https://drive.google.com/file/d/1mLEa0TH...sp=sharing
great all great.
a pig in the poke sack engine, is first tested in the floor or pallet or as you did, (to a battery)
cranked to see if compression is ok,
x4, sparks out. throttle blocked open so the engine can pump air.
ok its a good and if not, we check the timing belt, for slipped, they all do after 60k miles or so. 60k is spec.
if all 4 read 80psi not 180 then it cam slipped the belt.
if one cylinder is low lash is wrong, valves there burned, or head gasket bad or even a bad cam lobe or broken valve spring. (what matters most do the compression test first)
then we do more tests, if 1 or more fail.
the engine is a huge air pump 1.6L pump. and that is first, making sure it still is.
good luck to you.
