#1 of 3 2004 Lincoln LS 6 cyl 32,000 miles Engine Problem
Sep 23, 2009 (7:33 am)
My engine light came on. I had codes read. PO304 is the code. Mechanic said that the "Valve Guide Seals are Leaking" and there is oil on the pistons. He isn't sure if he needs to remove the heads to repair this. Estimate is $1200.00. I need some help from someone!

It's the valve cover gaskets, not guide seals. Just remove the valve covers, replace the gasket and clean out the oil. You may need to replace spark plugs and/or COPs.
