Longton Exhaust Fitting for Lotus

Lotus catalytic converter failure can be hard to diagnose as the catalyst becomes clogged with exhaust particle contamination or the Lotus catalyst is poisoned by fuel contaminants

A faulty Lotus oxygen sensor (Lambda sensor) can also cause damage to the Lotus catalytic converter due to an increase in unburnt fuel in the exhaust gases

Do you need a replacement Lotus exhaust, Catalyst or Sensor?
Use our form to request a Lotus Exhaust quote to fit the sections you need

The Lotus exhaust parts include: - Exhaust manifold, Header, Oxygen Sensor, Catalytic Convertor, Back Box (Muffler), Exhaust Pipe, Tail Pipe and a range of Lotus exhaust fittings

Lotus exhaust corrosion problems are usually easy to diagnose as a dramatic increase in engine noise as one of the Lotus exhaust sections or joints corrodes from the inside to form a hole

If the catalyst fails, your Lotus will probably fail the MOT emissions test.

Lotus oxygen sensor (Lotus Lambda sensor) failure usually occurs because of a build up of combustion mineral particles on the sensing element leading to the Lotus engine running fuel rich

Lotus Service - Lotus Braking Systems - Hydrauic Brake Maintenance

Lotus brakes can last for thousand of miles depending on use and regular service

The hydraulic brake fluid is a non-compressible liquid so braking pressure is transferred via the brake pipes to the wheels and operates a slave cylinder piston that forces the brake pads against a brake drum or brake disc

The brake pedal controls the Master Cylinder (a fluid filled hydraulic piston) that transfers stopping power to the brakes

Braking increases hydraulic brake fluid pressure

The enforced contact between the brake pads and brake drum or brake disc increases friction to slow down or stop the vehicle

Modern Lotus braking systems use hydraulic links to transfer stopping power

Lotus Disc Brakes and Drum Brake Systems

Lotus disc brakes have a pair of high friction brake pads mounted either side of a brake disc

In hydraulic braking systems, braking pressure operates a slave cylinder

Drum Brakes are an older system than Lotus disc brakes and use two half moon shaped brake shoes that move outwards during use to apply a frictional stopping force against the inside of a brake drum

Hydraulic braking pressure forces a brake calliper to press the brake pads against the disc to apply the necessary stopping force

Drum Brakes, if fitted, are usually found on Lotus rear wheels

Lotus Brakes - Lotus Brake Servicing and Maintenance

The brake pads on your Lotus should wear first

If the Lotus brake discs warp then they should be replaced immediately

Lotus Brakes will safely function correctly without the need for replacement for many thousands of miles

Lotus brake discs will wear and need replacing eventually and should be inspected for pitting

if the Lotus brakes overheat and are allowed to cool with pressure still applied for m the brake pads/shoes then it is possible for the disc to warp.

Lotus Steering System

One of the first signs of a potential problem with your Lotus steering system is uneven tyre wear

Common symptoms of Lotus steering alignment problems include:-
Vehicle Drift - Your Lotus tends to pull left or right when travelling in a straight line
Modern Power steering and Drive by Wire Systems do not have the same mechanical linkages between the steering column and drive wheels making it difficult to 'feel' how the steering is performing.

The tyre tread is rapidly removed from the inner or outer tyre edge of your front tyres

The tyres will need to be replaced much sooner than necessary until the steering rack is adjusted to bring your wheels into correct alignment

Your Lotus steering inspection can include:-

Lotus Tyre wear and wheel alignment

Steering Linkages for wear and corrosion

Wheel Bearings for wear - play or noise

Correct wheel balance, including spare

Lotus Services Braking System Servicing and Repair

The enforced contact between the brake pads and brake drum or brake disc increases friction to slow down or stop the vehicle.

The hydraulic brake fluid is a non-compressible liquid so braking pressure is transferred via the brake pipes to the wheels and operates a slave cylinder piston that forces the brake pads against a brake drum or brake disc.

Brakes can last for thousand of miles depending on use and regular service.

Modern braking systems use hydraulic links to transfer stopping power.

Braking increases hydraulic brake fluid pressure.

The brake pedal is attached the Master Cylinder; a fluid filled hydraulic piston.

Lotus Timing Belt or Cambelt

Generally Lotus belts should be replaced every 60,000 miles or less. So, if you have just bought a secondhand Lotus that has 40,000 to 80,000 miles then it is important to know if the timing belt has been replaced or needs replacing. Check the Lotus Owner's manual for your model for the recommended changing frequency

If the timing belt snaps it will most probably cause serious engine damage. The camshaft stops turning with some of the valves left in the open position. In a Free Running Engine there is enough clearance between a fully open valve and the piston head to avoid serious damage. In an Interference Engine there is no clearance and the engine relies upon accurate timing to keep the valves and piston head separated. With a broken timing belt; the inertia helps the crankshaft to rotate freely forcing the pistons to strike the open valves resulting in damaged valves, pistons, and possibly even damage to the cylinder head

High compression diesel engines are normally interference engines

Often it is prudent to replace a combination of items associated with the timing system. Most of the needed Lotus parts can be obtained as timing kits containing the appropriate timing components; such as: Lotus timing belt
timing belt tensioners
timing belt tensioner idler roller
front lower crank shaft seal
water pump gasket

Timing belts must be replaced at a specified manufacturer's interval. The timing belt should also be inspected regularly and replaced immediately if there is any evidence of cracking or fraying cuts or excessive wear

The toothed belt connecting the engine crankshaft to the camshaft is known as the Cambelt or Timing belt

Since Lotus Timing Belts are hidden inside the engine they tend to be forgotten when purchasing a used Lotus

The Timing Belt synchronizes the camshaft to the crankshaft position ensuring the valves open and close at the correct time in relation to the piston. Some vehicles use a cam chain in place of the belt or a timing gear system instead

Lotus Fuel Injectors - Fuel Injection

EFI - Electronic Fuel Injection
The Lotus fuel injection system is controlled by a mini-computer or Electronic Control Unit (ECU) that assimilates data from a series of temperature sensors and oxygen or lambda sensors providing feedback to help optimise fuel efficiency and power under a variety of conditions

Lotus Fuel Injection
Fuel injection systems mix fuel with just the right amount of air for optimal combustion & energy release in an internal combustion engine

Lotus Engine Mapping
The Lotus ECU controlling engine performance is pre-programmed with software containing embedded data on engine performance for different combinations of engine speed and acceleration

Lotus Re-Mapping Longton
The Lotus ECU can be replaced with a programmable ECU or re-mapped to electronically alter the engine performance characteristics

LPG Petrol or Diesel Metering
Fuel Injection systems have replaced carburetors for the accurate mixing and delivering of petrol, lpg or diesel fuel in modern Lotus vehicles

Lotus Engine Oil Change

Anti Oxidants
Preventing internal engine oxidation in your Lotus motor is the job of sacrificial anti-oxidants present in the lubricating oil; Anti oxidants are sacrificed to protect your engine and will eventually be depleted making it necessary to change your oil regularly

Oil Change Masterclass
Keep a small amount of the engine oil used in your next oil change in a sealed container; then when you check your oil level with the dipstick you can compare the lubricity or lubricating properties of the oil against your fresh oil:- If the oil on the dipstick seems thin compared to your reference oil sample; it may be time to get an oil change to keep your Lotus running smoothly

Synthetic Oil Change - Longton
Modern synthetic oils can last longer than old petroleum based multigrades because they are more inert with a laboratory designed molecular structure and fewer natural catalytic impurities that increase oil breakdown compared to the cheaper engine oils

Oil Composition
Engine Lubricating Oil is composed of hundreds of chemicals; some can interact chemically, polymerise, oxidise and break down with the extreme conditions of temperature & shear forces pulling the oil molecules apart in your Lotus engine thus, changing the lubrication properties.

Oil & Filter Change
A new Lotus oil filter and oil change shouldn't need a specialist Lotus engineer and is minimal compared to the cost of an Engine Rebuild; with regular maintenance and routine servicing working out cheaper than disaster recover when your Lotus engine fails

Oil Change Frequency
The mechanics rule of thumb with traditional multigrade engine oils used to be "change the oil every 3000 miles" but many vehicle manufacturers indicate 5000 to 7000 miles. Initially, follow the Lotus recommended oil change guidelines to ensure you validate your warranty.

Moisture Scavengers - Detergents - Acidity Regulators
Moisture scavengers, detergents and acidity regulators prevent all kinds of contaminants degrading and abrading the internal moving surfaces of your Lotus engine minimising the effects that water, particles, and fuel combustion residus can have on Lotus performance
Once they have absorbed the maximum amount of water and other contaminants; the risk of corrosion and failure in your in your Lotus engine increases

Longton:- Lotus Replacement Clutch

The centre of the clutch disc has a spline pattern that matches splines on the power input shaft of the transmission system

The Lotus clutch disc is, not surprisingly, a disc with each side covered in a high friction material. It is designed to engage with the high-friction surfaces of the pressure plate and flywheel. It is also designed to transmit power to theLotus transmission system

Disengaging the clutch acts on heavy-duty release springs to isolate the pressure plate so that the disc is no longer pressed against the flywheel

When the clutch is dis-engaged the clamping force is removed so the clutch disc spins with the flywheel and no power is transmitted

Engaging the clutch forces the clutch against the flywheel transmitting power from the crankshaft to the transmission shaft

Lotus Clutch failure often occurs when one or more of the high friction surface materials wears out on the disc. Even when the pressure plate is engaged and a clamping force is applied, there is no longer sufficient friction to transmit power without the clutch slipping. Normally the Lotus clutch disc and pressure plate are replaced. Replacing the Lotus Clutch is a major operation and it is sometimes advisable to replace a number of items, often supplied as a Lotus Clutch kit:-
Lotus clutch disc
pressure plate
release bearing
pilot bearing - bushing (when required)
internal Lotus clutch slave cylinder

The pressure plate comprises heavy-duty release springs, a metal pressure ring acting as a high friction surface to interact with the clutch disc, a thrust ring (or thrust fingers) for the release bearing, and release levers

Lotus Replacement Exhausts Longton

Explosions from the instantaneous ignition of the compressed fuel and air igniting in the combustion chamber creat a lot of noise that needs to be silenced in the urban environment

The exhaust pipework helps muffle and deaden the noise from the fuel combustion process

Corroded exhaust pipes allow fumes and noise to escape; increasing the risk of poisonous carbon monoxide entering the cabin and significantly increasing noise making detection an easy task

The Lotus exhaust system allows poisonous gases from the fuel combustionto vent into the atmoshpere away from the driver and cabin
