    Jim sure will sort some pictures out over the week-end for you, all I know is the standard location is a right pain for service tucked behind the vac tank and air filter housing, I will be moving it and the fuel lines for a more sensible set-up.

    Thanks Raymond and Simon, it looks like the four screw filter king is the way to go for a 5000S. I agree the location is a bear to get too.

    Cheers Jim

    There is probably space down near the fuel pumps or in front of the vac tank will study more easily serviced location.

    Well got the extension pipes straightened out, or at least as good as when they were manufactured, from images looks like a quicksilver system as for each bend there is some squashing of the pipes which is consistent with the quicksilver manufacturing methods, a load of fasteners ready for re-plating I prefer where possible to wirebrush the fastener clean, in some instances this is not always possible.

    If you pay Quicksilver enough money for a custom system, they can manufacture perfect mandrel bends in the pipes for headers & exhausts.

    Just having a laugh at the crazy prices for some parts - how about £84.21 for a standard M35x1.5 lock nut for the diff input shaft (item 23). Lamborghini now only seem to supply standard nyloc ring nuts not the original lock nuts. Image Unavailable, Please Login

    Sump now fully stripped, the engine clearly has been to pieces before as has the sump by the looks of it as the large ring nut clearly had been re-used as the original staking position was not aligned with the slot it had just been hammered into the thread to try and stop rotation. The ring nut retaining the splined collar was a PITA to get off even with an impact gun as the washer under it has a very fine dimpled pattern to stop anti rotation as well as it being a proper locking nut, the OE Lamborghini replacement is just a Nyloc ring nut.

    Will be time to get ordering some big bits soon, Will be going with new higher compression pistons just debating now on what to do with liners, either re-bore to 86mm, or just get new Westwood liners to original dims. Just concerned with over-bore these are getting a bit on the thin side at 1.75mm wall thickness at the base. Manley will be making new stainless valves. Hopefully Omega will be able to make the pistons.

    Engine block all cleaned up the same way, the castings for the block and heads have a slight purple tinge to them. Also started working up a push type clutch conversion which I believe can be made to work with a 365BB clutch assembly and a Tilton CSC, that simply becomes a bolt on kit.

    Just out of curiosity had a quick look at the release bearing, if you are careful the dust shield is easy to prize off working round the circumference with a Stanley knife blade to pop it up, this then allows the bearing to be re-greased, probably half the reason these bearings go bad is lack of lubricant as there is not a lab Image Unavailable, Please Login rynth seal. I will pop an o ring under the seal at least in an effort to keep the grease in. Worth checking at your next clutch service as it really is a 5min job that could save you thousands on the replacement of this part.

    It appears with some very small modifications to the cover housing (basically to dowel locations) that a BMW E34 M5 clutch will bolt straight up to the flywheel, couple that to a new flange for the guide tube to house a Tilton release bearing and looks like there is a viable route to a push type clutch - just waiting on some feedback from a supplier in the UK to fully confirm.

    Whilst the old clutch can be rebuilt a number of times, eventually the fingers fatigue at the ends where the release bearing digs in and the release bearing also has a finite life. The current cost of these parts is a joke even taking into account low volumes and L tax.

    It's pretty tight. Beyond the cooler, I can't see anywhere the lines go. They are not visible under the fender (when looking up past the tire). Do they run inside of the rocker panel?

    The oil lines are passing through the tubular frame section, the triangle under the sill, but don't have a Picture at hand currently.
    There must be a hole in front of the water radiator where they dive.
