To be on the clutch plate the oil has to come from the gearbox side.
Any oil from the engine side simply gets spun off onto the bellhousing.
If the gearbox has ATF in, then changing to Mobil-1 which is thicker might reduce leaking from the front seal a little, worth a try, or yes it's box out time, so engine out too.

It has got ATF so I'll try Mobil-1. Thanks for that. In the Steve Heath book he suggests you think the gearbox can be removed by moving the engine forward and up slightly.....is that correct? Any oil from the engine side simply gets spun off onto the bellhousing.

Do you know what type/make of clutch is in there? You'll have a lot of torque with a 450 motor so even if it looks OK it may be marginal. I have a standard clutch in my SEAC as that's what I found when I pulled it apart but I pondered for a while before deciding to make sure the new one was a reputable make - and it seems OK. The clutch will only see high torques in higher gears, as in low gears the wheels will spin before the clutch slips; so your description suggests the clutch can't transmit the torque. I'd be concerned if I found traces of oil on the clutch surfaces and I was expecting it to transmit high torques; I'm surprised it wasn't swapped out - clutch plates are cheap compared to labour rates!

It's an AP clutch. I'm going to try some Mobil-1 in the gearbox as I remember when they did the engine rebuild they changed the gearbox oil to ATF and it's since then the clutch started to slip. If that makes no difference it'll be engine out I guess.Interesting photos Darren. It's still looking good, although the engine is a lot less shiny!

Nice photos.
When was the gearbox rebuilt, as it's leaking lots of oil at the moment?!
The usual suspects for this are the output flange oil seal and the O-ring around the selector input shaft. Wear, combined with the usual thin oil (ATF) that's used in these boxes, makes for a constant-loss lubrication system...When was the gearbox rebuilt, as it's leaking lots of oil at the moment?!
