Determining why an engine does not run properly is a skill that eludes many and can stymie the most professional mechanics. That's why at All Star Auto, we approach our tried and tested methodology when isolating engine issues, ensuring the problem is rectified as cost effectively as possible. Our approach is to isolate issues based on seven main categories of performance issues: Rough idling, stalling, lack of power, pinging/detonation, excessive oil consumption, exhaust smoke and engine hesitation. By employing this methodology we get to the root cause of the issue as quickly and effectively as possible.
Rough idle could mean : Miss-adjusted carburetor , vacuum leak, worn/miss-adjusted breaker points, coil polarity wrong, fouled spark plugs or HT cables
Lack of power could mean: Insufficient ignition advance, secondary butterfly on carburetor not opening, metering rods/power valve not functioning, restricted exhaust, starving for fuel
Pinging could mean: Excessive ignition lead, carbon-laden pistons and combustion chambers, lean mixture, high cylinder-head metal surface temperature/coolant, EGR (if equipped) not functioning, ignition timing scatter from worn distributor bushing
Hesitation could mean: Weak accelerator pump stroke, vacuum advance not functioning, idle mixture screws set wrong, vacuum leak, insufficient amount of base timing
Stalling could mean: Idle speed set too low, massive vacuum leak, idle circuit in carburetor blocked, EGR valve stuck open, choke tension (when cold)
Oil smoke on start-up only: Worn valve guides/seals
Excessive oil consumption: Wrong oil viscosity, head gasket, oil diluted with gasoline, worn oil ring on piston, excessive cylinder bore wear/glaze, short trips/numerous cold starts
Diagnosing a problem takes thought, practical knowledge and patience. Thats why at All Star Auto we spend valuable time analyzing the situation with effective diagnostics that will result in correct repair.
An automotive clutch normally provides dependable service for thousands of miles. However, stop and go JHB traffic and those trips to the local PnP will wear out a clutch quicker than highway driving. Every time a clutch is engaged, the clutch disc and other components are subjected to considerable heat, friction, and wear. Operator abuse commonly causes majority of premature clutch troubles. For instance, "riding the clutch". There are five types of clutch problems- slipping, grabbing, dragging, abnormal noises, and vibration. It is important to know the symptoms produced by these problems to action the necessary solution and repair. At All Star Auto we employ this symptomatic isolation approach.
