Review on FEL-PRO VS 50529 R Valve Cover Gasket Set: Superior Quality and Performance by Scott Gendron

Well my valve covers don't leak anymore so they've done their job. The 4.0 V6 in my Explorer doesn't lend itself to such an easy repair, which is why I ended up paying to have it fitted (oh! back when you didn't have to take half a car apart to replace simple parts!). The hardest part is just getting to the valve covers, once removed it's not a difficult task. You can't go wrong with the Fel-Pro.
