[QUOTE="mcgovern61, post: 30404, member: 59"] Off the top of my head (and there really isn't much left inside there anyway :smilie_happy: ) the oil viscocity is thinning in the hotter temps because the radiator can only bring the coolant temp down to ambient air temps which in this case is 105 degrees. At 105 degrees, the engine itself is running warmer (hotter if you will) than when the coolant can be taken down lower. The reality is, the radiator isn't bring the coolant down to 105 degrees, it only brings the coolant down a certain percentage compared to ambient air temp. It is likely that the coolant is running at about 198 degrees on average at it's lowest temp returning to the engine in 105 ambient air. This is causing the internal engine temp to more than likely run higher since the oil is cooled via the block heat exchange and the bock is running hotter. That causes the oil to thin out more (lower viscocity) and less lubricant at the bearings, wrist pins, etc.....If your knock is from any of the components listed, it could be that it is caused by low viscosity oil. Every oil has an ambient air temp rating for this reason. [/QUOTE]
