I recently bought a 2018 Chevy Colorado Wt with the 3.6 gas V-6 I love the truck, its quick, gets good mileage when I'm not beating on it. But when you start it after sitting a little while (3-4 hours), it sounds like its going to throw a rod. Sounds like it has no oil pressure for a couple of seconds. I'm not sure but it may be worse when parked unlevel with the front higher than level. Its making me think I should get an engine preluber. I used to have one on my 1990 dodge diesel. electric oil pump, pump up oil pressure before starting and it ran 30 seconds to 2 minutes to oil the turbo on shut down. The dealer says the mechanic couldn't duplicate the noises. Total bull. Does anyone else notice this? Yes the oil level is full.
