Yes Virginia, getting one out sucks.
It's hanging up on the bolted motor mt. support and the main cap (Jon & Andy's thread). If I was smart, I would have dug out the engine crane before I put the car on jackstands. Now I have to move table saws, radial arm saws, generator and hope I can squeak the out beside the car. I want a freekin' shop that not a storehouse. |

yea, turn it so the front counter weight is up. the pan will fall right out.
don't forget to remove the oil level sensor from the right side of the pan. It gets all tied up in the windage tray. |

Did that, at least the weight was up in the right side of the block. I'll try that in the a.m. Still thing it's hitting the main cap. The other thing, the pan's sitting on the brakeline which eats up another 1/4 in. of clearance and the clip bolts are hidden by the motor mount supports, so that can't be moved w/o hoisting the engine. And, as Murphy tells us, I spent a halfhour moving saws and crap to get to the hoist. And, of course, I need 2 more inches of clearance to the C4 door to pivot the damn thing. Taking off one of the hoist legs to pivot it is a pain, they're really big. Yea, oil sensor's out. |

I spun the crank thru 180 while watching the counterweights.
Nope. I think the 1/4 inch brakeline is part of the problem so, the engine gets picked up tomorrow which means I have to take the bigass engine hoist leg off to spin it around. |

that's odd, Bill.
I have dropped my pan a couple of times and never had any issue except for the crank weight. I wish I could see this... |

Yea, isn't it? Since I was under the car, looking at the rod & counterweight while spining the crank, I'm sure. I'll take a pic tomorrow of where the pan's hitting the brakeline (this is keeping the pan a querter inch off the crossmemer). You can feel that it's close to coming out. I'd play more today but I volunteered to man the SCCA booth at The Motorsports and Recreation Expo today. |

Do they engineer things like that (the brakeline) deliberately?

I know I shouldn't, but...
 Now for something useful: I'm with bogus, I didn't have any issue with that brake line. Mine was getting stuck between the bolt head for the front main cap and the crossbeam. Are you sure this isn't your problem? Did you remove the little brace that goes across there? Attach file:  Oil pan 005 (highlighted).JPG (0.00 KB) |

What "little brace", Jon?
Yea, I know it's hitting the main cap bolt. The bottom of the pan is also sitting on the brakeline shown in your pic which pushes the front of the pan up into the main bolt. |

I had a little cross brace that went under the pan just behind what's shown in the picture I posted above. It bolts to the two angular frame rails in the picture. I can't imagine you would have left it in there, but it was worth asking.
Is your pan stock? keep in mind my experience was with a Canton pan, which although similar may be slightly different than the stock pan. Although I think up front they are near identical. |

No, no brace on the 92.
I'll take a pic later. When the rear of the pan is tipped down so that it clears the bell by a 1/16th, the bottomfront of the pan is on that brakeline and also on the boltin motot mt. bracket. Sliding the pan backwards, you can feel it hit the main. If my hoist wasn't stuck is a place where I can't spin it around easily, I wouldn't even have posted this. |

So, I got really pissed off since the piviot pin on the engine hoist wouldn't come out to remove the leg. Got under the car and hit the oilpan 3 times with a gloved fist (I hurt my fist). It did come out, tight enough to scrape the paint a bit.
If I ever do this again, I'll remove 2 motormount bolts and lift the motor a half inch. I was supprised how clean the pan was. I've seen a lot of pans and when I wiped my finger on the bottom, there was nothing to pull up. Also a pic of the bottom of my engine hoist, note the trolly that you use to move the rear of the hoist around with.

BTW, the leg on the hoist that I was trying to remove is sq. tubing, 3in by 4in. by 75 inches long with a 4in. steel caster wheel.

Hardly, Jon's talking about something else. Those 4 bolts hold the diagnoals that the motor mounts bolt to. Can't be removed w/o picking up the engine. |

I'll put it back on with my fist.  I took the pan off cause a small coolant leak (pump gasket) turned into a "while I'm in there" project. Since I had the w/p off, I wanted to look inside the MSD opti (10k miles)and the car had developed a small oil leak which I thought was the crank seal. It wasn't, it was the oil pan gasket. I don't put up with oil leaks on my stuff. If the GM engineers had put the brakeline a 1/2 inch more forward, the pan would have come right off. |
