Mediamab Posted January 17 Share Posted January 17 Figured as part of my first oil change I'll also remove the sump, give it a good thorough clean and maybe a quick spray to tidy it up. Receipts say rebuilt 8k miles (5yrs ago) but I feel like a thorough clean would make sense. I might be being thick but im really struggling to find the right bolts/washers/gasket online and ideally SS? Can anyone advise so I get it right? THANKS!

Mediamab Posted January 17 Author Share Posted January 17 Also as per the LT85 thread is Swepco oil even a good idea for the engine too? I have gone with the Valvoline Vr1 20w-50 for now... Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted January 17 Share Posted January 17 Sump gasket is black goo - there's a specific loctite product for it I think @Hybrid_From_Hell knows the number, or most likely the black sealant sold in most motor factors will be very close. I would not bother with stainless into aluminium, bolts are 5/16 UNC according to the parts book: https://www.lrworkshop.com/diagrams/land-rover-defender-engine/v8-petrol-carburetter/sump_53382 The engine just wants any decent quality 20W50, it's a very simple old hector. 1 Quote Link to comment Share on other sites More sharing options...
Mediamab Posted January 17 Author Share Posted January 17 Thank you @FridgeFreezer I have some Wurth high temp RTV Silicone - would that do the trick? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 17 Share Posted January 17 I'd see what colour the oil is that comes out, if only rebuilt 8K ago I can't see what removing the sump will tell you any more than looking to see if the oil has sparkles in it. Quote Link to comment Share on other sites More sharing options...
Mediamab Posted January 17 Author Share Posted January 17 Yeah was more just thinking good to ensure I’m starting life with the engine knowing it’s clean and no nonsense in the sump. Oil looks good looking in the filler cap also the choice of bolts on this engine is bugging. Endless multiple bolt sizes and washers galore so thinking good to resolve those! My exhaust headers are washers galore! Anything from 1 to 8! Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted January 17 Share Posted January 17 Exhaust manifolds to head you can get 3/8 UNC to 3/8 UNF studs with brass UNF nuts, much nicer. If it was rebuilt I'm guessing they didn't use nice new bolts all round then? Quote Link to comment Share on other sites More sharing options...
Mediamab Posted January 17 Author Share Posted January 17 It would appear they used any bolts they had laying around which worries me mildly about the quality of the rebuild! But I have a 3.5k receipt but I asked company for details but they said they don’t hold that far back. I’m just hoping the tapping noise I have when warm is the manifold gasket leaking. With the setup of bolts with washers I’m hopeful it’s the cause. Noticed it’s arguably louder in the truck than out! Quote Link to comment Share on other sites More sharing options...
