The engine has 190K on the clock and leaks like the Exxon Valdez.
I know it need a flywheel oil seal and also the one behind the pulley, plus the drain plug has an iffy thread so won't tighten up but looking around it seems to show a lot of the oil is on top of the engine too.
I removed the dizzy and found a flat dizzy shaft seal, the breather tower has an O ring under it and that was split and there was oil escaping from under the fuel pump too. The dipstick tube was also missing its O ring from its base.
I put an order for all the seals and gaskets in to Brickwerks so they should be with me in a day or two.
Luckily the paper gasket at the base of the oil filler tube was still dry as it seems its impossible to get to one of the mounting nuts with the silencer, heat shield and engine bar in place.
I removed the alternator and belt so i could get the crankshaft pulley off, but even with the van in gear, the handbrake pulled on tight and all the wheels chocked it still moved when i tried to undo the pulley nut.
Apparently theres a hole in the flywheel you can stick an M8 bolt in to lock the flywheel. Who knew? Bolt fitted in the flywheel and the nut came off with just a heave on a breaker bar.
With the pulley off i then struggled to get the seal out as access is pretty limited with the exhaust heat shield in place and coolant hoses everywhere.
The claw end of a hammer seems to do the job nicely though.
