Critical

Exhaust Smoke on Boost

Blue or grey smoke under acceleration often points to a failed exhaust-side gasket allowing combustion gases to escape past the turbo flange.

Critical

Oil Leak at Turbo Flanges

Oil seeping from the turbo inlet, outlet or oil feed/return connections indicates a failed sealing gasket or O-ring. Can be a fire risk on hot turbo surfaces.

Warning

Exhaust Noise Change

A blown turbo mounting gasket can cause a ticking or hissing sound near the turbo, particularly under load or during warm-up. Often mistaken for valve train noise.

Warning

Boost Loss or Hesitation

Exhaust leaks at the turbo flange reduce effective driving pressure, leading to sluggish performance, turbo lag, and possible limp mode activation.

Monitor

Burning Smell After Installation

Oil leaking onto a hot turbo or exhaust manifold after a recent turbo fit usually means a gasket was not replaced or was incorrectly seated during installation.

Monitor

MIL / Boost Fault Codes

Exhaust leaks at the turbo can trigger boost pressure fault codes such as P0299. Always inspect and replace gaskets before condemning a turbo or actuator.

1 What is a turbocharger gasket kit?

A turbocharger gasket kit is a set of sealing components designed to prevent exhaust and oil leaks during turbo replacement or service. Contents vary by application and may include turbo mounting gaskets, exhaust-side gaskets, and oil feed/return sealing gaskets. Always confirm contents by part number and OE reference before ordering.

2 Do I need to replace gaskets when fitting a new turbocharger?

Yes. Reusing old gaskets that have been heat-cycled or compressed increases the risk of exhaust and oil leaks after fitting. Replacing gaskets as part of any turbo installation is standard workshop practice and helps avoid costly rework, repeat visits, and potential warranty issues on the replacement turbo.

3 How do I find the correct gasket kit for my vehicle?

Match by engine code, OE reference number, and kit part number (1900-100-xxx format for Melett kits). Send us your vehicle make, model, year, engine code and existing turbo OE number — we will confirm the correct gasket kit before you order at no charge.
