Best ways to end engine valve sticking tapping noise safely
Best way to end engine valve tap noise without repair, and with a bit of driving instead.
Engine valves are essential to your engine transmission, power steering and radiator operation. I'll show you the pros and cons to end you valve tap easily, cheaply, yourself.
Here's why engine valves tap.
When valves become residue coated - from the goo film remaining behind when you change your oil, or fluids, that tar-like residue causes resistance to the valve closing speed, or closure. In transmissions, sticky valves causes rough shift, jerk slippage - and can end as describe here for engine valve tap - in the link below. Saving you a bundle of expense.
In engines - where there are 2 or 3 valves for letting in fuel and existing exhaust on each cylinder, they all may close in a sluggish fashion after 100,000 miles of driving.
However, one or more valves may be so dirty its closing speed creates a gap where a space appears on those parts that open and close the valve. As those parts rotate, they smack the valve closing the gap - which you hear as a tap tap tap. That's your problem. Tips for your fix...
Ways to end engine valve tapping.
Traditionally, us mechanic's disassemble your engine to get to the valves and associated parts that will be replaced as part of the procedure. With machining cost, labor, gaskets , and new parts involved, cost easily run to $2000 to $4500 to quiet the noise.
While synthetic oils have more additives in them, they do not have the complex cleaning action needed to remove the problem causing residues. Additives are helpful, but most part store and quick lube additives are 50 year old detergents or solvents that have little power to clean valves.
Solvents engine flushes clean well, too well in fact, and actually strip the critically needed lube film off engine parts as they do a quick rinse - the recommended time for solvent flushes in a motor is 2 minutes. You may have heard stories of engine failure after such a cleaning procedure. Stay away for old fashion detergents and solvent engine cleaners.
Chemistry to the rescue. Since residues start somewhere, and temperatures of 1800 degrees are involved, one company has discovered the chemistry to remove residues where oil cannot, and in metal melting temperatures - link given below. This DIY method cost a fraction of what an overhaul cost - and last many years. Wear reducers and worn space fillers add to the advantages for the benefit of and easy fix and long life, too.
The car owner can have these easy-to-use products sent to their door, and in a day of driving after the easy install, can clean and free their valves, and piston rings - the cause of sludge and sticky residues, and enjoy a clean-working, and QUIET engine again!
Hope this information becomes your best way to end engine tap noise - with repair - while you drive.
