Smailler engines with fewet cylinders do not enjoy an life in today‘s breed of mxzt Because the smaller engine must work harder to deliver adequate road performance, it now produces higher heat loads in a more confined space. In their efforts to make adjustments for heat and space, designers have introduced a number of new elements into the modern automotive cooling system. For example, except for a few large engine applications and some accessory drives, there is hardly a Vâ€"shaped belt on 1988 passenger cars Rather, a Vâ€"ribbed belt on a "serpentine‘‘ drive weaves around smaller pulleys, thereby replacing a number of traditional Vâ€"belts. The standard Vâ€"belt, however, is still found on more than 120 million cars (plus 40 million _ light trucks and vans) of 1970 to 1980 vintage. Motorists should continue to replace them every four years, ~ Do you think your car may be using too much oil? One sign an engine is burning oil is blue smoke coming from the exhaust pipe. There can be several reasons for this condition, the most common being worn valve guide seals. Here‘s why: The valves in a typical engine may open and close as often as 100,000 times per hour at highway speeds. The stem of the valve, sliding up and down in a guide, is fitted with a special seal designed to permit only a limited amount of oil to pass. (Some oil is necessary for lubrication, but too much creates oilâ€"burning problems). Eventually these seals will wear, harden or otherwise fail. That‘s when oil burning begins. Many of the conditions which cause an engine to burn oil prematurely are caused by vehicle neglect. One example of this is worn piston rings, which can wear out prematurely because of failure to change oil and filter regularly. Once the rings become excessively worn, an expensive "ring job" is the only remedy. With proper maintenance, however, an engine normally should go well beyond the 100,000 mile mark without needing new piston rings. lt'is essential to che;kv;he;;xâ€"gln: oil r(;gularl_v overâ€"full or smells like gasoline, it could mean it becoming diluted with gasoline. Thus, the oil becomes thin enough to work its way into the combustion chamber, evenually to burn and end up in the atmosphere as smoke. If you have to pump the accelerator to keep the engine from stalling, you may be pumping raw gasoline into the crank case. This situation can be avoided by keeping the engine in tune. Misfiring spark plugs can aggravate a situation such as this because they permit raw, unburned gasoline to wash into the crank case. Not only does this create hard starting, it also accelerates wear due to diluted engine oil Another factor in oil burning is a malfunctioning positive crank case ventilation (PCV) valve, which is intended to route oil vapors through the combustion chamber rather than permitting them to escape into the atmosphere. Remember: Excessive oil burning is a condition that gradually worsens and can affect other aspects of the engine. Early detection and correction are essential _If the PCV system is not in proper working order, it can be the cause of oil burning.
