Different cars will have different engine cylinders such as 6- or 8-cylinder engines. The higher they are, the more quickly the pistons can travel. The valve is the part of the motor that takes in lets out exhaust during the process where fuel is being consumed. There is usually an intake valve and an exhaust valve. Anything engine related, to the heads or valves, would cause seat recession or valve burnage; hints, the problem is with the valve seats themselves. Either they are defective, both times, or improperly installed. Period. Now, if the valve had receded further into the seat, and the seat was reground and the valve shimmed, then a new seat was put.

Valve Seat Recession. Exhaust valve seat recession (VSR) is a complex process affected by many factors of engine design and use. Amongst these however, high engine speeds and high engine temperatures are major factors in making an engine susceptible to VSR. VSR is a phenomenon experienced only by poppet valve four-stroke petrol engines. Some of these engines have been upgraded to harder valve seats over the years by their owners; if yours is among these, you can use unleaded fuel with impunity. If your car is currently running just fine, and has been running for the decades since leaded fuel was phased out, it is probably safe to continue running without lead substitute.

CD2, a fake lead additive has very nearly stopped all valve recession in my R/7'78 model year for 10 years now. I have some remarkable proof in an engine with way over miles with the stock valves still in it!!.
I found this stuff about 10 years ago in an auto parts store and its concentrated, using only a half ounce per 9 gallons of gas. Valve recession occurs when wear of the valve or seat inserts in an automotive engine has caused the valve to sink or recede into the seat in sert (as shown in Figure 1).
Excessive recession leads. This book aims to provide the reader with a complete understanding of valve recession, starting with a brief introduction to valve operation, design, and operating conditions such as loading and temperature. Before reading this book I had zero knowledge about engines except that I read it in my engineering days 15 years back.
As first expression, I was little disappointed to see the book in a spiral bound (although it was already mentioned on the site), and having black and white pictures/5(6).
INTRODUCTION Valve recession occurs when wear of the valve or seat inserts in an automotive engine has caused the valve to sink or recede into the seat insert (as shown in Figure 1). Excessive recession leads to valves not seating correctly and cylinder pressure Size: KB.

The growth of the valve seats market can be traced back to the early s. This is when the switch to unleaded fuel took place. Most of the engines in use had to have replacement valve seats inserted in the exhaust side.
The valves in your cylinder head are a vital component of your engine and undergo enormous stresses, opening and closing up to times every minute under normal operating conditions. When one or more of these valves are damaged, the result can be anything from reduced power and poor fuel consumption, to complete engine failure.The following additives have been tested as being effective against valve seat recession, and are approved for use by the Federation of British Historic Vehicle Clubs.
