bad oil leak
hi there I have a 94 f150 2wd the oil pan gasket is hanging out the drivers side. The whole underside is covered. It must be leaking while im driving cause it doesnt leave a big puddle while setting.I know i have to replace the pan gasket.The lifter covers are leaking too ,but about 6 inchs of the pan gasket is hanging out so I think thats the big problem. Does anyone know if I have to pull the engine up to do this ,its the 300 six cyl.? did they have much trouble with this ? But i have 150000 on it so its time for things to go wrong! thanks for any help

I've only personally seen 2 do this but have heard about alot of them doing it.You have to lift the engine some,but you don't have to pull-it.If your doing it in the driveway,on your back,with basic handtools,by yourself,it'll take enough time to ruin "that" day.It's not too bad to do on the 300/6.

I may catch some flack for this but here goes anyways.... I had the same problem with my 5.0 about 3 months ago. Since it is such a pain to replace the gasket I just loostened up all of the bolts, pushed the gasket back in, an retightened, but not too tight. I figured since there is 150K on the engine, if it didn't work, I had lost nothing but about 15min and I would just have to replace the gasket. But it hasn't leaked a drop since, so here's hoping.

Well, what I ended up having to do, was drop the pan, unbolt the oil pump. Since there wasn't room to pull the pan out, I slid the gasket in between the pan and block without getting it all the way free. Then I put the pump and pan back on. Still a major pain. But it isn't leaking.

I know that it sounds half-assed--but I had the same trouble on my 92 F150 5.0 V8 and I just dropped the pan about one half inch by loosening the bolts--without removing them--and then carefully pushed the gasket back in between the block and the pan gasket surface and then carefully torqued the pan bolts per the Factory Service Manual.
It hasnt leaked a drop of oil in the last 6 months after doing this. If this doesn't fix it--you can still replace the pan gasket. It just may not be necessary to replace it in all cases.
Edit:I just noticed that One-five-0 said the same thing that my post did. Well--anyhow---there are at least two of us that were able to make the original pan gasket work . This may work for you also--give it a try!

From the pain it was to get the pain mostly off, I would agree with you. I was already doing the water pump so the radiator was out. I couldn't have done it otherwise.
As long as it stops leaking, mission accomplished.

I replaced the oil pan gasket on my 300 without pulling the motor, but also with out completely removing the pan. Just unbolt the motor mounts, jack up the engine. the tranny will follow, no need to unbolt it. there is enough room to work the old gasket out, and the new in. not the funnest job but can be done with out motor pull. i did this on a 2 wheel drive model. can't say for sure that it would work on a 4 wheel drive.

Getting a Seal on things
I know this is kind of late but for anyone in the future that has to do this it should help a little. Two wheel drive f-150s with the straight six motor sit really low on their mounts. This is due to the suspension setup of the twin i-beam linkage running underneath the motor. Because of this setup, removal of the oil pan is impossible due to the fact that there isn’t enough clearance between the bottom of the motor and the I-beam cross member for the oil pan to clear the crank shaft and oil pump. The only way to remove the pan is to unbolt the engine from its mounts and loosen the transmission cross member mounts (but do not remove them) and then raise the motor up high enough for the pan to clear the bottom. Loosening the transmission cross member bolts and not the mounts allows the transmission to flex while the motor is raised without putting too much pressure on the rubber transmission mount. Plus it allows for a little more room to play with. I don’t recommend trying to insert a new gasket in between the pan and engine because its nearly impossible to get both surfaces clean enough to seat the new gasket properly. Any good mechanic will make sure that all gasket surfaces are clean and smooth to ensure proper sealing and fit. Hope this helps for any future gasket repairs.
