Question: I recently bought a custom car, a super bee of 1970 and plan to drive it in good weather for the auto show.
It didn't work until I tuned it
New spark plugs and inserts were installed and chrome air purifiers and aluminum valve door covers were installed.
The car suddenly started using oil, though it wouldn't show any real smoke unless I accelerated hard.
Will I be doing something wrong when installing the earbuds, or is it something else that causes the car to use oil?
Answer: You don't mention what engines are in your car, but most engines are either 383 or 440 cubic meters --inch V-8 engine.
There may be a few things that cause one of the engines to suddenly start using the oil, so let's take a look at the more common engines.
First, I will check the valve seal on the intake and exhaust valves.
I suspect that the car may have been in storage for a long time or has been driving very little.
Rubber parts harden with age, and valve seals may have hardened and broken when you start driving the car.
In this way, the oil can enter the intake manifold along the valve guide and burn in the engine.
Typically, when the engine starts after a night of sitting, this will show up as a burst of smoke.
Replacing the valve seal is not a difficult job and can be done without removing the cylinder head.
When removing the valve spring and replacing the seal, compressed air is blown into the cylinder through the spark plug hole to maintain the position of the valve.
When the valve cover is closed to check the valve seal, look at the PCV (
Ventilation on the right turn)
Valve opening in valve cover.
There should be a metal shield inside the valve cover so that the oil cannot be sprayed directly on the PCV valve.
Many aftermarket valve caps are not shielded, and the PCV valve directly sucks the oil into the engine intake.
This can lead to high fuel consumption.
Broken piston rings can also lead to high fuel consumption. This is a high-

If the ignition time is too far ahead of schedule, it may cause the engine to start, causing the piston ring to break.
You can test the condition of the ring with a cylinder
Leak test, measure the amount of air leakage per cylinder.
This is better than the compression test because the oil in the cylinder sometimes causes misleading readings in the compression test. kerr. jim@sasktel.
