Oil pan question??

Ok, gotta replace oil pump. Can I do it with motor in place on 84 258 and how big a job?? Any input would be great. Thanks.

No need to remove motor. Just pull the oil pan, and then the oil pump.

One of the bolts is really hard to get to Some unhook one engine mount, and raise the engine slightly to reach it. Or use a very small wrench. I used the small wrench, but replaced the bolt with an allen-head so next time will be easier.

I had to also remove the front drive-shaft, and cross-bar to get the pan out.

That's exactly right. Messy job but not too difficult. Don't mess with a cork seal on the pan - use the blue rubber one piece from felco.

That 2-piece cork seal was tough. The way its setup is you have to have it sitting on the block first, then set the pan onto it. Fine if you have the engine upside down on a mount....

What I did was put a very thin bead of RTV on the gaskets so they would stick to the block. That actually helped since it takes some work to get the pan into position.

You will have to remove the pass side motor mount to get the pan off. Make sure you have the right pickup tube for the pump. They made a couple of designs, search on here, been discussed before.
