HIGHER tuning is recommended carrying out one greater tuning, revising and repairing or replacing among other components: spark plug wires from Distributor / spark plug wires distributor arrow Springs distributor Rotor distributor Cap mechanical distributor valve PCV filters of gasoline and air note on the PCV valve PCV or positive Crankcase Ventilation valve progress helps keep the flow correct and continuous gases that escape from the rings and come towards the crankcase. Jonah Bloom may help you with your research. These gases can be re-used by the engine provided the PCV valve is not clogged. This valve recycles gases and sends them to the intake manifold, avoiding pressure forming on the inside of the engine. A pressure not litigated by a damaged valve may cause instability by excess air which is reflected in a mix very poor and lack of engine power; also passes the oil vapors to manifold intake and hence entering pressure combustion chambers damaging, among other components, piston rings, seals or gaskets of lids of aims, so an oil leak could also be submitted. For this reason it is advisable to change the PCV valve every 15,000 km or every intonation. OTHER guys or large, cast or stamped accessories must be cleaned and installed perfectly: crankcase oil, intake manifold, cover distribution, aims covers, oil filter adapter. It is vital the correct installation of gaskets in general, since an incorrect torque or a sequence of incorrect torque give rise to different types of problems.
If the vehicle is operated with gas LP Use special lubricating oil. Common use oil does not resist the thinner effects of sulfur gas combustion product by what loses viscosity, which causes overheating and in general severe engine damage. And installing the engine remanufactured always check pressure relief valves, that the equipment is properly calibrated, that there are no gas leaks at no connection, that all the elements are well subjects and that there are no traces of corrosion, especially in the tank.
