Stopping Jeep Oil Leaks - Oil Embargo

Posted in How To: Engine on September 1, 2009

Yeah, yeah, all Jeeps mark their spot. If we hear that one more time we're gonna puke. The real truth is, not all Jeeps mark their spot. Only the ones with shoddy maintenance, worn components, and lazy owners mark their spot. And while most tend to attribute that oil-puking-excuse of a saying to older Jeeps, even newer models from the '80-'90s aren't free from inherent sealing troubles.

Case in point: at around 100K-150K miles almost all 2.5L and 4.0L Jeep engines develop a leak at the two-piece rear main seal, the back of the valve cover gasket, the harmonic balancer seal, or any or all of the above. And while the apathetic Jeep owner can simply add engine oil as needed and tell the neighborhood association, "It's not leaking, it's just marking it's spot," the problem can be taken care of in a couple of hours with simple hand tools. So check it out as we put a stop to the oil leaks on our little 2.5L engine. And if you've got a 4.0L, the process will mostly be the same.
