I'm trying to get my 89 MJ oil tight again. It appears to be oozingfrom the head/block junction along the passenger side. I've clean everything up a few times and that's where new oil shows up. Its not the typical valve cover, oil filter adapter, or RMS and they've all been done. Its dry above the joint and just sopping wet below it. Is this common? I really don't feel like pulling the head just an oil leak, but it is getting pretty bad.
