kstomper 08-23-2002, 07:44 AM so i replace the rear main seal, front timing cover seal, pan gasket. now the oil blows out the dipstick!!?? wtf is up? its not a great deal, but is kinda messy. would my vacuum lines need rerouting? btw its a '79, 258 with the minimal in vacuum lines and a motorcraft 2 bl.:confused: snacksnack 08-23-2002, 08:11 AM is your crancase vent thru the valve cover plugged or excessive blow by, could even be in the head if its all gummed up kstomper 08-23-2002, 08:18 AM there are 2 vent lines in the valve cover, one has a pvc on it and its new, the other is routed to a gas filter and dropped down beside the clutch linkage. should i remove that filter and route the line to the charcoal box? a little oil comes out of the filter, but without the filter, alot of oil come out. JeepinIan 08-23-2002, 08:34 AM How is the compression? You may have a worn out eng and it is excessive blow-by. kstomper 08-23-2002, 08:59 AM about 110,000 miles, but pulls like a mofo. has a plume of smoke at start-up and has black oil blowing out the tailpipe when i rev it. :rolleyes: bigjeepinYJ 08-23-2002, 09:05 AM Originally posted by kstomper about 110,000 miles, but pulls like a mofo. has a plume of smoke at start-up and has black oil blowing out the tailpipe when i rev it. :rolleyes: :D Souds perfect to me! Bonestripper 08-23-2002, 09:58 AM Could be blow by from the rings. Do a wet/dry compression test. snacksnack 08-23-2002, 10:31 AM time for a stroked, 4.0 head, rebuild:flipoff2: JeepinIan 08-23-2002, 10:49 AM Originally posted by kstomper about 110,000 miles, but pulls like a mofo. has a plume of smoke at start-up and has black oil blowing out the tailpipe when i rev it. :rolleyes: If it's blowing smoke, then it could be pulling better than it is now. kstomper 08-26-2002, 07:42 AM thanks for the info guys. i will do a compression test on all 6 cyl. :D 89MJComanche 08-26-2002, 03:18 PM I had a replacement rubber hose for a line of the PCV to the manifold... When it got hot it was sucking shut and the only place for oil and pressure to escape was the dipstick. I bent a piece of brake line like tubing to replace the rubber hose PCV line... It does not leak any more and now I am going to bend that kind of metal tubing and replace all my vacume lines. I might even get some galvanized 1.5inch electrical conduit and place all my wires in side of it and bend the stuff nice and neat all around the fire wall etc. Then I could get me some of that bright blue FOO FOO paint and make dress the motor up real well. I would check your PCV hose. | |
