Valve Stem Seals

[Hugo]

Hey would anyone know what can possibly cause bad valve stem seals, all my car has is a exhaust, JLT CAI, and a tune. Thanks

What, exactly, is leaking and where?
To answer your question though,
Poor installation
Defect in valve stem
Defect in wheel
Age of rubber seal
Damage to valve stem

But knowing more background would be helpful in finding a solution. For example, a valve stem could be leaking from its core which could be as easy to fix as tightening or replacing the core. If it's leaking where the stem comes through the wheel then it's a repair for a tire shop.

it’s fine, any thoughts ?

Is it a reputable tune? It's most likely the cause.

Manufacturer defect, improper oil change interval, car sitting for too long, etc
