Used on a Toyota Yaris as similar to Toyota oem. Worked very well on timing chain cover and sump. Itโs at a good price point, created a great seal when used to recommended bead size torque on a challenging sump pan ( the one with 2 bolts inside bell housing)

Very good
A little expensive for the amount but definitely worth it for where a gasket isn't used in the first place; like the Honda Deauville engine side cases.

Does the job
Unlike some Loctite RTVs, this didn't arrive cured hard in the tube before first use, and remained usable even after opening and storing for a couple weeks. Success! I've used it to seal a timing case cover on an old engine, which has a large coolant channel going right through it. So you have engine oil, vibration, coolant and a lot of temperature gradients in the mix. It's holding up just fine so far. No leaks. It would be better if delivered in a plastic tube as the metal ones eventually crack, and spoil the contents.

Reliable high-torque RTV silicone โ my husbandโs go-to gasket maker
My husband picked up this Permatex 82194 Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker for some repair projects. It does exactly what itโs supposed to โ forms a strong, durable seal. What works well: โข Stays flexible enough to handle vibration and temperature changes but cures rigid. โข Good for making custom gaskets on oil pans, valve covers, water pumps, and similar automotive/equipment parts. โข Easy to apply from the tube and cleans up nicely before it sets. โข Trusted Permatex quality at a fair price for the 3 oz tube. Heโs used Permatex products for years and this one performed as expected. Solid choice if you need a high-performance silicone gasket maker for mechanical repairs.
