Exhaust Manifold Gasket
A ticking or tapping noise that gets louder as the engine warms up often means a leaking exhaust manifold gasket. This gasket seals exhaust gases where they exit the engine, and a leak can cause loud noise, lost power, and even let fumes into the cabin. We locate the leak and replace the gasket to seal it back up.

- Gasket burnout from constant high exhaust heat
- Cracked or warped exhaust manifold
- Broken or loose manifold bolts and studs
- Corrosion from age and road salt
- Repeated heat cycling weakening the seal
Frequently asked questions
Why does my exhaust manifold tick when cold?
A leaking gasket lets exhaust escape through a small gap. When the metal is cold the gap is widest, so the ticking is loudest until the engine warms and the metal expands.
Is it safe to drive with an exhaust manifold leak?
It is risky. The leak can get worse, reduce power, and let dangerous exhaust fumes reach the cabin, so it is best to have it repaired soon.
Do you replace broken manifold bolts too?
Yes. Exhaust bolts often seize or break, so we remove and replace any damaged bolts or studs as part of the gasket job.
