Motor repairs are needed in the event of a major breakdown or engine rebuild. In some cases, older model cars may need to be rebuild and repaired after long-term use and significant mechanical breakdowns. A car that has overheated due to radiator malfunction or extreme operating conditions may also require motor repairs.
Major motor repairs may include bearing or seal replacement, which could include bottom-end bearings, head gaskets, oil seals and gaskets at the bottom of the engine and fuel system seals or fuel rails. You may also have to rebore the engine, replace pistons and rods, camshafts, crankshafts and other major components such as the gearbox.
The price of motor repairs will depend on the availability of parts, the age and type of your vehicle and a range of potential variables such as the cause of the breakdown. Sometimes, a mechanic will not be able to tell the extent of the damage until major labour has been done to pull the engine apart (such is the case with head gaskets). If finding parts is a problem, try searching for parts online.
If you have to perform major motor repairs, be sure you are using a qualified and trusted professional. If you choose to make major modifications from OEM, you may also have to enquire about engineering. Be patient with your mechanic, and make an enquiry about a second opinion if you are unsure about your current motor mechanic.
For most repair work, a general mechanic can organise and perform motor repairs.
