Frequently Asked Questions

Why are crush washers (oil drain plug gaskets) important?

Crush washers are designed to deform slightly upon tightening, creating a perfect, one-time seal between the drain plug and the oil pan. They must be replaced with every oil change to prevent slow leaks and ensure the plug remains securely fastened.

What is the benefit of using gasket making material?

Gasket making material allows mechanics to quickly cut and create custom gaskets for older, rare, or highly modified vehicles where pre-cut replacements are unavailable or hard to source. It provides flexibility and reduces downtime.

Should I use RTV sealant with a differential cover gasket?

If you are using a high-quality, reusable rubber or composite gasket (like the LLR-D044), RTV sealant is generally not required and can sometimes interfere with the seal. RTV is typically reserved for metal-to-metal sealing surfaces or when using a thin, traditional paper gasket.

How do I know if an exhaust gasket needs replacing?

Signs include a loud hissing or ticking noise coming from the engine bay (especially on startup), a strong exhaust smell inside the cabin, or visible soot/black residue around the flange connection. Exhaust gaskets degrade due to extreme heat cycles.
