4.2 with Major issue...possible causes?
A guy I work with has an '88 YJ in pretty good shape, only a little surface rust here and there, everything works, etc. Something very bad is going on in the engine. It's a straight 6 (so Im thinking it should be a 4.2?) , about 160,000 on the Jeep. It blows oil out the breather like crazy. He was driving it and stopped prior to it running out of oil (actually, it's only just over a quart low), and it turns over fine. It didn't start when I tried it but I didnt hear any noises indicating major bottom end problems. I'm think there are a few possibilities to cause this, a burned piston, cracked ring(s), or head gasket. Anyone seen this problem before particularly on the 4.2? I'm working on buying this rig as is and fixing for use as a trail rig. Here's the Wrangler:
'00 XJ Classic > Stock DD
'88 Grand Waggy - Bone stock pseudo-barnfind
'78 CJ5 - Under minor rehab
