Exhaust Manifold Gasket Replacement

You don't want your engine's exhaust pouring into your car. The exhaust manifold connects to your exhaust pipe, carrying gases towards the muffler until they exit via the tailpipe. It is the main gasket that seals and pressurises the entire exhaust system. Gaskets are used to seal gaps between two different surfaces. The surface where the exhaust manifold meets the engines parts must be sealed - this is what the Exhaust Manifold Gasket does.

Oil Filter Housing Replacement

Your oil filter is critical to your engine’s maintenance. It needs something to screw into and somewhere to get the oil from. This is where the oil filter housing comes into play. The oil filter housing has the simple existence of holding the oil filter and feed lines. Most cars will never need to worry about the housing, the oil filter is obviously the most serviced item of the assembly. However, if there’s a problem with the oil filter housing, it needs to be fixed.

Oxygen Sensor Replacement

Due to modern environmental concerns, car manufacturers have brought a raft of measures to help lower carbon footprint - namely emissions. This is where the oxygen sensor comes in. This is a sensor that is connected to your exhaust manifold which detects the level of oxygen in your exhaust gas. This helps ensure that the car is running with the exact air/fuel ratio it needs for peak performance – in both power and efficiency.

Accelerator Cable Replacement

A lot of cars used to trust a steel cable to transmit inputs to the accelerator to the engine. Modern cars use a drive-by-wire system. Over time the cable will need adjusting as it stretches. In some rare cases, if you’re a real fast and furious driver, it can snap and require replacing.
