My K&N will stay in. Thank you Blackstone Labs.

Amen shortshift, I also believe the test are meaningless if you are replacing a turbo as I am on Monday. I dont care if the silicone levels are low there is dirt getting by the filter into the turbo bearings causing premeature wear in my case. I have carefully watched my oil change intervals and cleaned the K&N every 15K. I have never had this type of problem before and have 250K plus mi on gas engines. I still run a K&N in my 93 wrangler but I wont in the turbo diesel!

davedd,hate to say this but you probably bought your turbo problem on yourself by overservicing your K&N to the point that it was worn out. I drive in extremely dusty conditions and have only been servicing my filter every 50k,it probably could go 100k though. I don't even open the airbox at all until I'm going to service it. Every time you open the air box whether you remove the filter or not you are taking a chance it won't reseal correctly. Same goes for a OEM paper filter. With a boost gauge,filter minder and removing the turbo hose at every oil change to see if dirt is getting by you have plenty of ways to check your filter without opening the box.

Ditto's to opening the air box. You should treat an open air box like having the valve cover off= OPEN ENGINE.
don't rely on the filter minder, put a vac. gauge in the cab See/Ya

Forgot, What will give if the air filter doesn't? the turbo seal. they run really good for about 5 minutes, then you're out of oil!

A parting shot to those who question the ability of oil analysis in detecting dirt that bypasses filters and seals. this from Blackstone Labs website:

" With new diesel engines costing up to $20,000 each, it only makes sense to take care of yours, so you can get that 1,000,000+ miles before an overhaul. Insidious problems can crop up - which can be identified early on by oil analysis - that can and will drastically shorten engine life. Some problems are: abrasive dirt escaping air filtration, antifreeze contamination, and fuel dilution, to mention only a few. We can detect these problems and recommend a solution. "

With my truck's set up, I absolutely need to run the psychotty air with the kn filter to keep exhaust temps down if I want to run the engine at the loads that I have been accostomed to run it. Sure, if I wanted to dial it down, I could get by with a stock filter but I like it this way. I will continue to do oil analysis but not necessarily to check for silicon. All aspects of these engines should be examined when they are run at these power levels and oil analysis is just another tool to help keep yourself informed.
