Are the Coyote motor timing chain tensioners kept tight with oil pressure when the engine is running? The reason I ask is my car started the barbeque tick at 27,000 miles with an oil change. Only happens when the engine is warm at operating temp. Cold it's quiet as a church mouse. Cold oil is thicker and would provide more pressure to the tensioners. As it warms less pressure/tension. I took a mechanics stethoscope and probed the motor. I located the tick at the timing chain area of the block. Definitely coming from this location. I read people change to a thicker oil and it goes away. So can people with more mechanic knowledge than I have please answer this? Does this sound plausible? Lower oil pressure > lower chain tensioner pressure > slack in chain > ticking sound. My car goes in the shop next Tuesday.
