How much vacuum is needed to crank a good engine - answer 3-5 in. Hg
What noise does a noisy hydraulic lifter usually make? - answer Consistent
ticking noise
What is spark plug preignition? - answer A hot piece of carbon or metal inside
the combustion chamber prematurely ignites the air fuel mixture
Detonation is primarily caused by what? - answer Low octane fuel in a higher
octane engine, too far advanced ignition timing, high engine operating temp.
Or excessive carbon build up in the combustion chamber
A high pitched squealing noise when the engine is accelerated can indicate
a? - answer Loose or glazed drive belt
Black Exhaust smoke indicates what - answer The air fuel mixture is too rich
Blue grey exhaust smoke indicates? - answer There is oil burning in the
combustion chamber
Excessive white exhaust smoke indicates? - answer Coolant leaking into one
or more cylinders
The three common causes of excessive oil consumption are? - answer Oil
leaks, valve guide/valve seal problems, or piston or piston ring problems
, What is the lowest acceptable freezing point for coolant, that the cooling
system would still be considered well protected? - answer -25 degrees celsius
When a vehicle suffers from from worn valve guides and or bad valve stem
seals, when will you see the exhaust smoke - answer During deceleration
because of the high intake vacuum that occurs during deceleration.
You see excessive white smoke coming from the tailpipe what are the correct
steps to check where its coming from? - answer 1st check coolant level
2nd do a compression test
3rd do a cylinder leak down test
4th send compressed air into the problem cylinder and watch to see if you
have bubbles in your coolant in the radiator or pressure tank
what can cause coolant to leak into the combustion chamber - answer A
blown head gasket or a crack in the block near a water jacket.
What can cause oil to leak into the combustion chamber? - answer Bad
piston rings, bad valve guides or seats.
Before blaming either the valve guides or valve seals for an oil consumption
problem you should first check what? - answer Verify that the oil return holes
are clean.
What should you check for when you have no or low cranking vacuum? -
answer A substantial air leak
What does PCV valve stand for? - answer Positive crankshaft ventilation
What does EGR stand for? - answer Exhaust Gas Recirculation
