This was in the Blackstone Labs newsletter.  I get one of these oil analysis reports with every other oil change on the vehicles I plan to keep for a long time.  No, its not my Jeep.  I had a 2000 Wrangler at one point, but we sold it.

	There's a bad cylinder head casting floating around out there in '99 model Cherokees. 0331 is the number to beware of. There's a crack that forms between two valve seats IIRC that is commonly mis-diagnosed as a blown head gasket by unknowing mechanics. Not sure if these heads can be found in 2000 Wranglers or not but I guess it's possible. With 300K miles on it, very likely a head gasket or something else. That's an interesting one. Blackstone is a great company and I've found their reports on our engines very valuable. Mail them a sample every two or three oil changes just to keep an eye on wear materials. Good way to catch things like this.

	that sounds less stupid than the 2012 JKs (first use of 3.6 pentastar) that had casting sand left in the head and an undrilled oil galley. Lots of left head issues. Thankfully they wised up and started not giving grief about replacing the head right off the bat. but for this report, 7k on oil for a 16 year old 4.0 seems a bit long, unless they are using good long life Amsoil XL or signature. My interval is 7.5k but I still use Amsoil XL just to be safe. An extra $1/qt is cheap enough insurance, especially with the fuel dilution I'm getting (last oil dump was thin and had strong gas smell... weird). Edited by BlackBird - 03 August 2016 at 7:14am
