The mechanic I use for compqny vehicles recommended that, but said the symptoms (to him) seem to indicate I might have bad rings. A leakdown would either support or refute that (or should). My son thought it could be the turbo, which some on here have said as well, but a lot of smoke is coming out of the valve cover breather. Not sure a turbo would do that??? The nuisance stuff isn't a huge deal...I've had it for almost 13 years...a lot of the little stuff has been done in the last 4 or so. I’d say your on the right track. as for smoke out the breather. “A lot” is subjective. It’s is smoke mist steam? Is there pressure behind it? Plug it. Does it pop the dip stick ?
