I driven both the 3.8 & 4.0 and find during acceleration and/or engaging passing gear a very noticable engine noise/roar compared to other vans I've driven. I searched the forums about and little is mentioned in regards to this . Anyone else find this to be an issue.

the van has 40,000 miles on it , and has developed a tapping noise like a bad lifter. oil pressuren was checked and is normal. the upper engine was taken apart, the rocker assemblies checked, the engine is spotless inside. no abnormal clearence problems were found. we removed the cylinder heads , replaced all the lifters, reassembled the engine , and when it was started after the engine warmed up , the same tapping noise appeared. both my freind and i are mechanics with over 20 years time in the trade.
