I purchased another Tahoe, 2003 LT 4wd 5.3, took and smogged it and no noticeable leaks at all. Next day I drove 200miles to pick up new wheels, on way back I got a check engine light, engine temp and oil pressure fine and not acting up at all. Got home and shut it off and noticed smoke from hood and large oil leak under truck. Code was a knock sensor, reset it and checked oil and was like 3qts low, it was blown all over bottom side of car everywhere making hard to pinpoint. Took to reputable mechanic shop and are saying they see three leaking places and could possibly be valve covers, oil pan, rear main or all 3. Going to let them start from top with valve covers, cheapest and easiest. My question is what if any of them could cause such a lose that fast? They have had on rack running and only see small leaks from around those areas. Any insight or help would be appreciated before I spend $2k+ on an oil leak on Tahoe I didn’t even have two days
