engines that sit for a while, unused... question.

Hi all,
i'm swapping my 1J for a replacement one, as mine is on its last legs..
Anyway, i've sourced a replacement engine, but the problem is that its been sitting a while and the guy who i'm getting it off (respected soarer bloke in the UK) recommends the following as he says the rings will now be dry of oil, due to it being sitting in a corner of the garage for some time...
"the rings will be ok, just dry until the oil get rounds.
what I can do is, take the plugs out, pour some engine oil down the bores and put the plugs back in, this will oil everything up, and this is a good thing to do when an engine has been stood for a while.
the only down side to this is, when you do start it up the oil that I have poured down the bore will burn and it will smoke like Bill Lewis for a while, maybe 10 20 minutes, but this isn't a bad thing, as it oils all the internal parts.
you let me know if you want me to do it, I can say that if it was mine I would do it."
So.. the question is.. is this a good idea? I'm not doubting him but he did say for me to get some other opinions..
Cheers
adi

hmm ud have to be VERY careful how much oil you put in there, you might end up with some nice bent rods or valves or something

you would need to use alot of oil for that to happen. compression lock i believe?
I am also interest in other peoples opinions on this. I also have a motor thats been sitting for a while

i mean if u dumped a wad in the cylinder, it wont compress like air/fuel, due to it being liquid, hence the bending of parts. on second thought it probably wouldnt, the starter would probably just crap itself before bending something.

I've used sewing machine oil. It's very thin, penetrates the rings easily and burns of in a minute or so when you start up. Only need about 25ml - buy a 100ml bottle and put one quarter in each cylinder. Rock the engine a bit if you can to move the oil around and then turn the engine over once or twice by hand so it lubricates the bore a bit as well.

another (old farm) trick is to:
attach cheapo oil filter
fill the crankcase with desiel fuel,
let oil soak in for a while,
if engine is out of car, rock around to slosh this oil everywhere
remove spark plugs and squirt desiel fuel down into pots,
crank engine for a while to get the desiel flowing everywhere,
drain the fuel and allow to slowly drain out of oil galleries,
cleanup oily mess that came out of spark plugs,
replace filter,
fill with normal oil,
crank until oil flowing everywhere
refit spark plugs
fire up and run rich (but at fast idel only)
check oil pressure up
you'll probably need a spare battery and a charger as you'll flatten a bttery doing this
we even briefly ran engines with desiel as a lubricant to clean up oil residue from inside crankcase - tho not advised for minimal tolerance engines.

cheers all... it seems the general opinion is to get him to do it..
Manny, yep its smithies  I had a look at a Soarer TT the other day and his engine was sweet compared to mine.. mine was noisy, smelly and smoky compared to his.. so i've decided to do the swap.

I've left an engine to sit around for a few years.
I poured sewing machine oil down the spark plugs holes then turned the engine over by hand (or roll car while in gear) a few times to move the oil around. Car has run fine since.

I'd say your best option would be to unplug your EFI fuse and crank you motor a few times. Let it sit for a while and then crank it again so the oil's up top. Through the fuse back in a start her up.
No matter if you perform any of the above tricks listed by the other guys, you should be alright starting it, even without any treatment as you shouldn't be redlining it on first time you crank the darn thing.
My two cents...

The main problem with starting an engine that hasn't moved for a while is the rings binding to the cylinder walls. It is the initial turnover that will do the most damage so leaving some sewing machine oil in there for a few hours then hand turning the engine is your best bet. Its a little less violent than letting the starter motor do it.

that's the shit to use alright, it penetrates every little slit and bubble because it is very very thin.
i wouldn't worry about hydraulic lock if you use about a teaspoon in each cylinder, every day, for about a week prior to start up. and turn the engine over a few times every day too.
this way, you can be sure nothing cracks / breaks / shears dude to oil gunk and/or rusty rings.
