New Equipment !

Christmas came early here at Auto Stop as we now have some NEW and EXCITING equipment! With two 2 post hoists, a 4 post hoist, a wheel balancer, a tyre changer, a workmate press and a wheel alignment machine, we can now service, balance your types and align your steering quickly, efficiently and further improve our already outstanding quality and service for you, our valued

Along with our four original two post hoists, we now have two NEW Powerex SL2900Falso_sl2900fr_large 2 Post Vehicle Hoists.

We have also purchased a Powerex SL3500W 4 Post Vehicle Hoist. This is not only used for servicing your vehicles and imagesCAG008X1checking them over, but also to align your steering and wheels with our new Butler Speedliner 6080WS wheel alignment machine.

The Butler Speedliner 6080WS System is a machine to detect all the vehicles specials fgfdangles. These angles are detected by four detectors with microprocessor technology, infrared measurement systems and data transmission; meaning we are able to align your wheels efficiently and with outstanding quality while you wait.

The Summit 1700TI Tyre Changer has been designed exclusively for imagesCAJ9MBCRremoving and mounting tires from and onto rims from 10″ to 24″. This makes the changing of your old tyres to your new tyres easier and less time consuming, along with the outstanding quality that we offer.

We have also purchased a Summit 1350 Wheel Balancer designedimagesV01TFLEA exclusively for balancing wheels with a maximum diameter of 1000mm and maximum weight of 75kg. The calibration system is sufficient to cover different wheels from motorcycles to cars and light trucks.

 The Autopro-Up Superman Multi Press  is designed to disassemble hfdhafd

wheel bearings, suspension bushes, shock absorbers, ball joints and gears.

Come in and say “hi” to your friendly team at Auto Stop and book your vehicle in for a service or a wheel alignment with our new equipment.

Don’t forget, this month only when you get one family vehicle service, you will save $55 on your second vehicle’s service!!! *voucher must be shown upon booking*

A Basic Guide To Engine Valve Failure

Engine Valves

The valves in your cylinder head are a vital component of your engine and undergo enormous stresses, opening and closing up to 2500 times every minute under normal operating conditions. When one or more of these valves are damaged, the result can be anything from reduced power and poor fuel consumption, to complete engine failure.  The two most common types of valve failure are bent/broken valves and burnt valves. 

Bent Valves

The most common failure of valves is bending or breaking as a result of contact with the pistons. The valves contacting the top of a piston is due to incorrect engine synchronization caused by timing chain/belt breakage and incorrect fitting of new belts and chains. If you suspect your engine may have bent or broken valves, it is crucial not to attempt to start the engine as this may result in more costly damage being caused to the cylinder head, pistons and cylinder bores. 

Bent Valves Caused By A Broken Timing Belt

The bent valves above are a result of a fatigued timing belt that has broken. Your timing belt doesn’t last forever and needs to be replaced according to the manufacturer’s service guidelines. Replacing your timing belt is cheap insurance against costly engine damage. 

Burnt valves

A Valve Starting To Burn

The other common type of valve failure is valve burn, or burnt valves. Essentially this is caused by combustion gases escaping between the valve and valve seat when they are not sealing correctly. The hot combustion gases are forced past the valve which starts to burn away the edge of the valve, progressively getting worse the longer it is left without being rectified. Normally this type of failure affects the exhaust valves only, but it can also damage the intake valves.

A burnt valve will cause issues with your vehicle’s performance and fuel consumption. Rough idle, reduced power, backfiring, and misfire are all symptoms of valve burn. If your engine is showing symptoms like these, we recommend you get your car checked by a trusted mechanic, as continual driving with a burnt valve will cause more damage to your engine, and will in turn cost more to repair in the long run.

Possible causes of burnt valves are:
   

  • Excessive localized heat

    Burnt Exhaust Valve

  • Combustion gases escaping past the valve and concentrated at only one point
  • Irregular valve sealing with cylinder head valve seat. Carbon residues generated by irregular combustion (poor mixture) will appear at the seat region and will jeopardize the sealing between the valve and its seats
  • Deficient refrigeration is another factor, due to partial obstruction of the cylinder head cooling.  As a consequence, the valve is cooled inadequately
  • Incorrect valve clearance can jeopardize the valve sealing and also cause this type of failure
  • Running a dry fuel such as L.P.G resulting in inadequate lubrication of the valve seat, causing the valve seat to fail and consequently, the valves

To help prevent this type of failure, there are a few things you can do. Maintain a clean, efficient cooling system so the engine does not run too hot,  use good quality fuels to help prevent carbon build up on the valve seats, and have your mechanic regularly check the valve clearances are within specifications.   

If your vehicle is using an aftermarket L.P.G fuel system, you must check that the engine is L.P.G compatible (most are NOT). In the event your engine is running L.P.G but is not L.P.G compatible, valve failure is imminent. It will generally be less costly to have your cylinder head removed and modified for L.P.G before the valves start to burn, rather than wait until the damage is done. Once the L.P.G modifications are complete, it will be safe to use the L.P.G without damaging your engine.

The Damage That A Lack Of Servicing Can Cause

You may think that having your vehicle regularly serviced is not essential however the following situation that one of our customers found themselves in may cause you to reconsider!

The customer came to us earlier in the year wanting a service on his Hyundai Getz – it had done 51,000 kms & its last service was 30,000 kms ago.  While carrying out the service we found that it had low compression due to the rings on the pistons being full of carbon deposits as highlighted in the picture below.

The piston rings are full of carbon deposits which caused low engine compression

This damage was a direct result of the vehicle not having had an oil change in 30,000 kms.  As a result, the engine had to be fully dismantled, cleaned and rectified costing the customer in excess of $4,000.00.  Had more regular servicing been carried out on the vehicle this damage would not have occurred and the customer would only have been up for the cost of a service – a much less costly exercise!

Has it been a while since your last service?  Even though you might not have experienced any repercussions yet it is most often the case that damage is already being done to your vehicle’s essential components.  Don’t keep putting it off until it’s too late!  To arrange an inspection of your vehicle today simply fill in the booking request form below.
