Permatex 80036 Valve Grinding Compound, 1.5 oz.

Works as it should. Can usually count on Permatex to make a quality product that does what it's supposed to and this one is no exception.

Used to lap a flywheel to a crank. Worked great.

Yes this inside a socket every time a bolt starts stopping out. Fills in a loose areas and grabs very well. Put it in the first time your ratchet or wrench slips and you’ll never have another stripped out fastener again

It works, but for REALLY GOOD valve lapping the other stuff where you have double grit separate compounds is better. This stuff here is neither really fine nor really coarse. It is somewhere in the middle. It may seal the valves somehow after some lapping, but it didn't give me the great results of the fine single 220 grit stuff when I did a vacuum check with the valves and 22+ InHg using a manual vac pump and 15 seconds minimum until losing the vacuum. I couldn't even get a vacuum over 15 InHg and it lost it just in a few seconds. Some valves were already in that condition before even lapping them. Sooo, bottom line, if you JUST somehow want to lapp a bit then you can use the stuff here. But if you want GREAT results and a verifiable result with vacuum pump check of the intake and exhaust channels and valve seats of your engine then I'd recommend buying also some finer single grit stuff 220 grit or even finer for that last lapping stage. Keep in mind every engine is different so your mileage may vary. Because valve sizes may vary, materials vary, etc. I am actually rebuilding a Jeep 242 with 0331 head engine. The valves and seats of the exhaust system were in fairly good shape, just the intake valves and seats needed some tlc and those are bigger. But I lapped all of them until I got my 22 InHg and 15 seconds vacuum hold results.

Very quick delivery. Items are as advertised. I would do business with this vendor again.

Valve grinding compound is an old school product used to help remove stripped screw heads. A little dab of this in the Philips head and it will grip the screwdriver and extract the screw perfectly. I'm an airplane mechanic and come across stripped out screw heads constantly. What time saver, Oh yeah it works well on valves too.

Works great

Used this valve grinding compound to repair a crossthreaded lockring on a vintage Williams double pawl B-52 Super Ratchet. I knew I was in trouble when it was a bear removing the lockring from my recently acquired vintage ratchet wrench. Took a superhuman effort to get the lockring moving initially, and it didn't get any easier loosening it. It was a battle all the way, I was bending the watchcase back remover tool I was using to engage two of the slots. After I got the lockring off, I could see that the threads were definitely messed up. I could only get the lockring screwed back in only half way before some serious binding occurred. I put some of this valve grinding compound on the threads and worked it slowly, back and forth, advancing it more and more, then backing it off, tightening back and forth. Applied a couple more dabs of compound a few more times. In about 5 minutes, the threads were cleaned up enough that the lockring was able to be tightened all the way in without forcing it at all. Cleaned up the internals, lubed it. And the wrench is now so smooth and will serve me for many years to come. This product definitely saved this sweet tool.

Good

使い勝手は良いです。粗目や細めなど考えず、この1本だけでバルブ擦り合わせを完了していますが、エンジンパワーは良好です。

Excellent paste. It makes hand lapping the valves easy. It starts medium, gets finer and stays where it needs to be. I've been using the wrong paste and struggling, now with this stuff it's like a dream.

Meine vermutlich 20 Jahre alte Dose mit vor und Nachschleifpaste von T war völlig hinüber. Da Ersatz der blechernen, roten Doppeldose inzwischen 50x mehr kostet, wie der alte Preisaukleber in DM bewies, suchte ich eine Alternative und stieß auf dieses Zeug für ein Viertel des Preises. Da ich es oft bei US Pro Motorenbauern gesehen habe, warum nicht? Lieferung wie immer blitzschnell und auch gleich am wartenden Golf 8V Kopf ausprobiert. Das Ergebnis war eine echte Überraschung! 1. Man braucht nur eine wirklich winzige Menge pro Ventil, entsprechend einem kleine Streichholzkopf. Nicht mehr nehmen! Bei neuen Ventilen noch weniger! 2. Die Paste legt kraftvoll los und wird recht schnell immer sanfter, das anfängliche Kratzen geht in ein Gleiten über. 3. Dann ist man schon fertig. Leicht fleckige, beginnender Einbrannt, wird problemlos entfernt, vor allem von gepanzerten Auslassventilen, die vorher Schmirgelpapier ignorieren. 4. Das Ergebnis ist hervorragend, es gibt keine umlaufenden Riefen die bei dem alten Produkt von "T" normal waren. 5. Durch das Herstellen von Vor- und Nachschliff in einem Vorgang, ohne reinigen und umsetzen, spart man mehr als 50% Zeit. Ich war jedenfalls viel schneller fertig als gewohnt. 6. Wenn man zu viel Paste verwendet, dauert es länger bis das Finish entsteht. Man schleift also zu viel und zu lange. Neue Ventile brauchen wirklich nur eine Spur, wo man von der Teroson Pampe einen fetten Tropfen braucht. Mein Tipp: Nicht aus der Tube verwenden, sondern einen kleinen, halben Tropfen (wirgklich klein!) auf die Fingerspitze und damit 4 oder 5 klein Tupfer direkt auf den Ventilrand. 7. Wer weis wovon ich rede, sollte das Zeug unbedingt ausprobieren. Würde von mir 10 Sterne bekommen, wenn es die gäbe. 8. Ich schätze das man mit einer 60 Gramm Tube locker hundert 8V Köpfe machen kann, wer deutlich mehr macht im Monat, sollte sich einen Vorrat anlegen.

works fantastic for sharpening the blades of my reel mower. Easy to apply.
