The only oiling that the piston sees is from splash oiling - thicker or thinner oil is not going to affect this. See if your attitude will get you a more in-depth answer from others. The only one with an attitude is you man; you're assuming I don't even know what piston slap is, and that's all I know about this issue. Usually piston slap is what goes away as the piston expands in the cylinder or with thicker oil. Valvetrain noise is always there because there's nothing really that happens after a car warms up to completely eliminate it. Yeah it might lessen then noise as things expand under heat, but not 100%. The piston rings fit into horizontal grooves in the pistons. The rings expand against the cylinder wall and seal the combustion chamber. This ensures that the engine maintains a consistent level of compression.

Jan 31, 2009 · With all those thick additives in there, it could stop piston slap or a rod or main knock. Drive it a while and it may return as the additives thin and break down. If you pull the pan, look for any bluing of the rod/main caps (sure sign of a spun bearing). Pull a couple of caps, look for scratching/scoring of the bearing or journal. The cause of the piston slap is a combination of the taper of the piston along with the fact that the skirt length has been shortened a bit to reduce inertia ( this allows for a quicker reving engine). This allows the piston to rock a bit in the cylinder when cold and causes the piston slap that we hear.Guided reading rome_ republic to empire lesson 4 rome builds an empire answer key
