Cold morning valve tapping and our Do-it-yourself remedy that stops tapping in minuts.
You would think engineers would design engines to stop your engine valve tapping.
They have in one sense, but failed in another. What they can't figure out a
slolution for is blowby - that causes the tap.
Blowby is a term describing escape of combustion around the piston.
Blowby fumes contain heat – double
the temperature of what oil can take. This is the cause of your tap. And the remedy we like and recommend, stops blowby.
It also contains a 100 gallons of mositure, a cup of acids, a gallon of gas fumes, and a handful of carbon.
All that makes small amounts of sludge. It collects around places like inside valve ajusters and on valve stems. Valves run hot as they are operating in the actual combustion area. The stems on your motors valves will burn the lube oil. This also forms varnish – meaning the oil converts to a pigment.
So, how does sludge cause Cold morning valve tapping? Is there a cheap way to end the problem for good?
Take a moment to understand how valve lifters work – lifters, a term meaning they are ajusters. In this cause lifters cause a tap sound when oil under pressure is blocked from energizing the actual adjusting part of the lifter portion. There is a lifter for each valve.
The adjusters purpose and the cause of your Cold morning valve tapping.
The valve lifter works like this: It sits on a cam lobe and as it goes up and down it pushes the valves up and holds them up and open for a brief moment, then drops away.
As the lifter and cam drops away the
valve, with an attached spring, forces the valve down following the
lifter downward. Over time, wear on these parts – which is twice
that of all other parts, creates a gap. That is your Cold morning valve tap area.
The valve lifter is hydraulic, meaning fluid makes the adjuster part work. The adjuster is a small wooden pencil eraser sized piston. The piston top has a hollow at its top – made to always maintain a constant contact with the bottom of the valve stems, and take up wear space as it occurs.
This assures that your motors valves will open sufficently long enough to let the right amount of fuel into the combustion process.
To hold the valve adjuster piston up a one way valve lets oil in and closes such it traps that oil keeping the adjusment perfect.
Sludge will keep that one way valve open or hold ir open after you shut the motor off for the night. Next morning, the piston will drop as the oil leaks away pass the sticky one way valve. A space appears, and the tapping sound your motor makes.
If the above is not your Cold morning valve tapping problem, the problem is varnish on the valve stems. Varnish acting like tar on a hot tin roof creates resistance to movement.
What ends both lifter tap problems and removes varnish that slow the closing of the valves so a space is created?
And what ends the lifter space problem when it comes around to push up your to open the valve? What is ther to end the space and free the lifer adjuster so it quits smacking the valve closing by eliminating the gap each revolution with a tap tap tap?
