It does sort of sound like late timing. How many shims are under the injector pump
. On mine, I've only one shim. I generally just listen to the injector popping while slowly turning the crank and note the location on the flywheel. If I remember right its one degree per shim, so you would need to remove 3 shims.
is generally cooling
related. If you have the U bend discharge elbow
, the area just inside the elbow
where the water
is injected tends to build up mineral buildup. Actually there can be mineral buildup in the 90 degree elbow on it. I use a small screwdriver and or bicycle spoke to break up the mineral deposits in both.
If there is mineral deposits, odds are there is mineral buildup at the exhaust
hose side too.
