Hey all,

How difficult is it to remove the sump with the engine in situ?

Does the crossmember have to come off?

I'm going to pull the pistons, hone the block and change the rings and BE bearings at some point.

Ta
Rich

Pull the motor.

You can remove the oil pan/sump with the engine in place, just have to remove the crossmember as you suggest; done it a number of times. However you're talking about a full rebuild, and at that point, if you're gonna hone the cylinders - might as well have a shop do it right.

At that point, it is much easier to remove the whole engine and do it on a stand.

+1 especially if your clutch is nearing the end of its useful life or you would like to also replace the main bearings.

Clutch is under 5000 miles old, and main bearings would be great - but they are NLA until someone makes some new ones.

Problem is I have no where to put an engine on a stand, no room under cover. Also I have no wya of transporting the block to a shop, it won't go in the elise and the landy is 100 miles away (It only does 25mph!)

The plan was:

Drop the sump, pull the head, pull the pistons, pull the flywheel
hone bores DIY
New BE bearings (Assuming they look ok) new rings, new crank seals
Rebuild

Mains would be great, but until they actually turn up I'm just going to hope they are OK...

No need to pull the flywheel unless your rear main seal is leaking. You can replace the rings and rod bearings without pulling the bell housing. You will have to remove 3 of the lower bell housing bolts however since they bolt into the oil pan.

How do you plan to pull the flywheel with the engine still in place?? Thats a hell of a lot more work then just pulling the block out.
I thought Dan had the main bearing supply fixed...or he had 4 sets for sale??

I'm not sure about the mail seal, I'll have to inspect it more carefully, they are £40 so I'd rather not change it.

I’ve changed the oil pan gasket with the engine in place once, really painful.

Take the time to pull the engine out. It’s so easy when it stand it front of you.
Good luck

I took the sump off with the engine in to do the big ends. I didn't think it was that hard, especially as I didn't need to take the crossmember off (didn't occur to me that I'd need to). A lot easier than taking the engine out without a crane and another body around to help.
