I'm looking at taking my G40 off the road in the very near future and stripping it down and give it a good overhaul. Obviously, during this time, the engine is going to be sitting around not doing a lot. What are the best things to do in order to ensure it'll still be in a good state when it's re-commissioned in the future? I was thinking of doing the following:
-Oil and filter change. Run it up to temp to get the new stuff circulated around nicely.
-Drain the fuel tank.
-Remove any fuel components (injectors, fuel rail, fuel pumps etc) and let all the old fuel evaporate so it doesn't turn to sludge inside.
I've read elsewhere recommendations about dropping some oil down the spark plug holes, but as the G40 pistons are dished, I'm guessing it's not such a great idea of these. Are there any recommendations for keeping moisture away from the cylinder walls whilst it's all out?
I was thinking of also turning the engine on the starter once in a while to keep the innards moving. If I just connected the starter directly to a battery with some hefty cables, would this be okay, or is it a really stupid idea?
If anyone else has any other hints and tips, I'd appreciate it! Thanks!
store the engine somewhere dry
put some wd40 down the plug holes to protect from humidity and cover both intake and exhaust ports with paper or and old rag.
don't drain the engine oil, let the crank/oil pump soaked on it.
from time to time, you can turn the engine by the crank bolt a few turns just to avoid seizure.
when you put it back to the car, check all sensors, drain the oil, put new one in, turn the engine by and for a while before crank it, just to fill all oil channels, after that, crank it and let it idle for a while and check for noises, leaks and connections.
about the g-lader, while on the car, before disassembly, spray some PTFE with the engine running to get oily for storage.
Ideally store the lader somewhere warm and dry. Under a bed maybe.
I'd spray some light machine oil or similar down the bores, not WD40. WD will wash any oil residue off the bores, and once dried will no longer repel moisture effectively - so its use may actually promote corrosion.
When storing my engine for 18 months or so I just tipped a bit of engine oil down the bores, left it with the plugs in and taped up the ports, and turned it over by hand whenever I remembered.
Perfect, thanks for the tips gents!
turn it with a spanner every couple of months or more if you can , stops the rings sticking to the wall of the bore

Sorry to drag up an old thread. Whilst the engine hasn't been removed from the car yet, almost everything is disconnected and I'm hoping to get it removed in the next month or two. Before I stopped using the engine, I changed the oil and ran it up to temperature. However, I was wondering as it hasn't been used for a long time, is there any risk of corrosion in the drier areas of the engine such as the cylinder walls?
I've since put a few drops of oil in the spark plug holes and turned the engine by the crankshaft bolt. However, I was wondering, won't most of the oil likely sit in the piston dish? Are there any other things I should be doing to protect the internals from corrosion or am I worrying about nothing?
Thanks!
just turn it over from time to time by hand, that'll deposit oil up the cylinder walls. unless it's being kept in very damp conditions then it shouldn't be a problem.
Ah, nice one. Thanks :) Does the piston pick up a bit when it's down then?
well if the oil runs down the bore it'll collect on the piston rings so that'll spread it about when you turn the engine over. I've never had any problem with bores rusting with engines that are left for long periods of time, I just turn them over by hand every few months.
Sounds good, thank you :)
