Will someone who is a professional registered mechanical engineer step up to the plate and give their expert opinion on the lubricating properties of todays oils and materials engineering and whether or not the oil will break down on temps below 280 resulting in component failure?
Are the pistons of this engine cooled by oil? If so, would not the oil dripping back to the base pan be hotter than any other part of the engine being cooled by the oil and returning to the base pan as well as the oil scraped from the cylinder walls? If this is the case, the oil cooling the pistons/cylinder walls will be significantly hotter as the top of the pistons/cylinder walls are in direct contact with the extreme temperatures from combustion. Is the oil temperature sensor in the base pan? I would suggest then that highest oil temperatures will be in the base pan and not necessarily in the valve train or bottom end. If so, the oil then is cooled somewhat on its way to the engine's critical components such as the bearings and cam lobes? What might one expect the oil temp to be in these ares of the engine?
