Frequently Asked Questions

Q: Does this kit include the transmission seals?
A: Yes, this is a complete engine and transmission rebuild kit, meaning it contains all the necessary gaskets and oil seals for both your motor and transmission components.

Q: Are the valve cover gaskets included?
A: Yes, this specific kit includes the necessary formed rubber valve cover gaskets, unlike some other aftermarket sets.

Expert Pro-Tip: When replacing oil seals, always apply a light film of clean engine oil or assembly lube to the seal lip before installation. This prevents the seal from burning up during the first few rotations of the engine. Also, ensure your sealing surfaces are perfectly clean; even a small scratch or bit of grit on the shaft can cause a new seal to weep oil immediately.
