Hey everyone I own a 2016 durango r/t and love it. No problems with it. That’s why I traded in my Toyota for a ram truck. Well I traded in my Toyota Tacoma for a 2014 ram big horn 1500 4x4. 60,000 miles on it. 5.7 hemi with 8 speed. I noticed a few days after owning it, the engine sounded whiny, almost like a super charger was under the hood. It’s much much louder under the truck than in the engine compartment. I had the truck at home a total of 4 days after signing papers and it’s been at the dealership for almost 3 weeks now. So far they have.....
Run engine without belt to isolate engine from accessories
Separated engine from trans and ran just on the flexplate without torq converter bolted on
Replaced all the roller lifters
Put in 40wt oil
So far after all this the engine is still whining. Next step they say is check oil pump and main bearing caps. I had a suspicion the noise is coming from the catalytic converters or the exhaust somewhere in that area. Do you guys have any thought on this at all? It does it in drive, park, neutral. Under load, or free rev.
Here’s a pic of the truck. I’ll try to post a video too
