How do you set the valve lash on an inline 6?
SETTING VALVE LASH ON AN INLINE 6 STEP 1: Remove all valve covers from the engine. STEP 2: Rotate the crankshaft until the engine is at TDC #1. Use the markings on the flywheel to determine when the engine is at TDC. Check the rocker arms on cylinder #1, which is the cylinder closest to the flywheel.
What was the length of the AMC 4.0 engine?
Connecting rod length was 6.125″ – similar to the discontinued 199 which was phased out in 1970. The 4.0 is one of AMC’s best-known engines. It was one of four AMC engines kept in production when Chrysler bought AMC in 1987. Chrysler engineers continued to refine the engine to reduce noise, vibration, and harshness.
What should the vacuum be on a normal engine?
Normal Engine: On a normal engine, accelerate to around 2000 rpm and then quickly release the throttle. The engine should snap right back to a steady 17- 21 “hg vacuum. Steady low between 5-10 “hg vacuum: This indicates that the engine has a leak in the intake manifold or the intake gasket.
What does steady low mean on engine vacuum test?
Steady low between 5-10 “hg vacuum: This indicates that the engine has a leak in the intake manifold or the intake gasket. This leak should be easy to find because it would be making a loud hissing noise. Steady low between 10-15 “hg vacuum: This reading indicates late valve timing.
What does it mean when your vacuum reading is uneven?
If rpm and vacuum are uneven, the cylinders aren’t pumping equally. The engine probably has leakage past the valves, rings or head gasket. If the vacuum reading is pretty steady but cranking speed is not, you’re probably looking at a damaged flywheel ring gear or starter.
What should the vacuum reading be on an OBD 2?
If you’re testing an OBD II car, check for evap-related DTCs when you finish testing to be sure none set. Run the engine at idle, low cruise (1800 to 2200 rpm) and high cruise (2500 to 3000 rpm). Note the vacuum readings, and any fluctuations, at each speed.

Which is the best description of a vacuum?
