RTV Silicone Sealant (Gasket Maker)
RTV sealant is a silicone paste that cures in air to form a flexible gasket between engine parts.
What is RTV Silicone Sealant (Gasket Maker)?
RTV stands for room-temperature vulcanising. Some engines use it instead of cut gaskets on sumps and covers. Oil-resistant and sensor-safe versions exist. Old sealant must be cleaned off completely and the surfaces degreased before applying new RTV.
How it works
Moisture in the air makes the paste cure into a rubbery seal that fills gaps between surfaces.
Why it matters for your car
Too much sealant can break off and block oil passages or pickups. Respect the curing time before adding oil or coolant.
