Thread Sealers for Engine Builds
A thread sealer fills the small gaps between mating threads so fluids cannot seep past a fastener. Engine builders use it on studs and bolts that pass into oil passages or coolant jackets, where an unsealed thread can let fluid weep out over time. Sealing those threads during assembly helps keep the engine clean and dry and avoids chasing leaks later.
Right now we have 1 thread sealer in stock, from ARP: the ARP Teflon Sealer 1.69 oz. It is a straightforward choice to keep on the bench for fastener work during an engine build or repair.
Check whether each fastener threads into a fluid passage. Those are the threads that need sealing.
Follow the fastener maker's instructions on whether to use sealer, lubricant or both, since this can affect torque readings.
Clean and dry the threads before applying so the sealer can do its job.
Apply a thin, even coat and wipe away any excess before final assembly.
To narrow things down, pick your vehicle to see what fits.
