Sump Bolt, Leaking & What Does It Do/Hold?

[Spoony]

As you can see in the pic the right rear side bolt in the sump (BFii T) has some oil leak/weeping.

I'm guessing maybe the bolt has a gasket or oring on it and perhaps just needs a tighten or a remove & refit. However I'm wondering what these bolts are for? Do they hold something inside the sump? If I was to undo this single bolt would something fall in the sump?

Main cap bolt I think.

You sure it's leaking form there?

[Spoony]

oh really, so not something that should be just undone. So the main caps are bolted in place using the sump on these? The sump is pretty full on looking vs usual tin pan I guess.

Will take another look, but it certainly looks like it, much more oil immediately around the bolt than anywhere else. Doens't drip on the ground though.

Should be fixed under annoying 'extended' warranty (oh the joys of these), but am using a mates mechanic workshops so thought I'd find out for myself first. (I'm sure he will also and be sure not to go dropping anything in the motor).

it doesn't actaully hold the main caps in place, they hold the sump on more than they support the mains. Undo the bolt and use some three bond gasket goo under the head when replacing. Re-torque to factory spec which is 58nm.

also check the engine mount hasn't leaked as they are hydraulic but I doubt it.

cheers spool, good info!
