Product Features
The Permatex 80037 Valve Grinding Compound has several features that make it a useful and versatile product for valve grinding and seating operations. Some of these features are:
– It aids valve grinding and seating operations by removing burrs, surface defects, carbon, gum and corrosion that may interfere with the flow of air or fuel through the valves.
– It can be used for lapping and grinding chromium, which is a common material for engine valves. Chromium is hard and resistant to wear and corrosion, but it also requires proper grinding and lapping to ensure a smooth and tight fit with the valve seats.
– It mixes with water to form an easy-to-use paste that can be applied with a manual or power-operated valve lapping tool. The paste has a good consistency and lubricity that allows for smooth and efficient grinding without excessive friction or heat generation.
– It does not contain any harmful or corrosive substances that may damage the engine parts or pose health risks to the user. It is also easy to clean up after use with water or solvent.
Product Benefits
Using the Permatex 80037 Valve Grinding Compound can provide several benefits for your engine performance and maintenance. Some of these benefits are:
– It improves the seal and compression of your engine valves by creating a smooth and uniform contact surface between the valve stem and seat. This reduces the risk of leakage, blow-by, noise, vibration, and power loss.
– It restores the efficiency and functionality of your engine valves by removing any deposits or residues that may impair their operation or cause them to stick or burn. This enhances the airflow and fuel delivery to your engine cylinders, resulting in better combustion and performance.
– It extends the life span and durability of your engine valves by reducing the wear and tear caused by friction or corrosion. This saves you money and time on repairs or replacements.
– It is compatible with most types of engine valves, whether they are made of steel, aluminum, titanium, or other alloys. It can also be used for other applications that require lapping or grinding of metal surfaces, such as sharpening reel-type lawn mowers or repairing tools.
Product Application
To use the Permatex 80037 Valve Grinding Compound, you will need some tools and materials such as:
– A valve lapping tool (manual or power-operated) with suction cups or adapters to fit your valve stems
– A clean rag or cloth
– Water or solvent
– A container or tray
– Safety glasses and gloves
The following are the general steps for applying the product:
1. Clean the cylinder head and valve parts thoroughly with solvent or degreaser to remove any dirt, oil, grease, or carbon deposits.
2. Remove the valves from the cylinder head and mark them according to their original position (intake or exhaust) to avoid mixing them up.
3. Apply a small amount of the compound on the valve face (the part that contacts the seat) using your finger or a brush.
4. Attach the valve stem to the lapping tool using the suction cup or adapter.
5. Insert the valve into its corresponding seat in the cylinder head.
6. Rotate the lapping tool back and forth between your hands (for manual tools) or turn on the power switch (for power tools) to create a grinding motion. You should hear a scraping sound as the compound works on the valve and seat surfaces.
7. Check the progress of the grinding by lifting the valve slightly and inspecting the contact pattern on both the valve and seat. You should see a bright and even ring of metal around the valve face and seat. If not, continue grinding until you achieve the desired result.
8. Clean the valve and seat with water or solvent and a rag or cloth to remove any traces of the compound. Make sure to clean the valve guides as well to prevent any abrasive particles from entering the engine.
9. Repeat the process for the other valves until all of them are done.
10. Reinstall the valves in their original position and torque them according to the manufacturer’s specifications.
11. Reassemble the cylinder head and other engine parts.

– “I used this product to lap my valves on a small engine rebuild. It worked great and made a nice smooth seal between the valves and seats. It was easy to apply and clean up, and it did not damage or scratch any of the parts. I would recommend this product to anyone who needs to do some valve grinding.”
– “This product is amazing for lapping valves. I used it on my motorcycle engine and it made a huge difference in performance and compression. It was very easy to use with a drill and a suction cup tool, and it took me less than an hour to do all four valves. The paste has a good consistency and does not dry out or clog up. It also cleans up easily with water.”
– “I bought this product to sharpen my reel mower blades, and it worked like a charm. I followed the instructions on YouTube and used this compound with a cordless drill and a paint brush. It took me about 15 minutes to sharpen all five blades, and they cut like new. The compound is very effective and does not require much pressure or speed to work.”
– “This product did not work for me at all. I tried to use it to polish some scratches on my stainless steel watch, but it did not make any difference. It was too coarse and abrasive, and it left more scratches than before. It may be good for valve grinding, but not for polishing metal surfaces.”
