Default Starting 2.5 LPT engine unused for 4 years

Hello there,
My 1998 V70 2.5T has been sitting for a number of years. I would like to get it back on the road, but am worried about lack of oil around the pistons, etc, after this time and possible damage when I would try to start it.

Might anyone be able to advise me on the best approach to take?

Many thanks.

I'd take the plugs out and spin the engine on the starter for a few minutes to get some oil around. Do this for 20 seconds or so at a time, to save overheating the starter motor perhaps? May need to re-charge the battery after this, but plugs back in and give it a go. Make sure that the plug leads are as far away from the plug holes as you can, to ensure a stray spark doesn't ignite the mixture coming out of the plug holes - or better still, disable the fuel pump while doing this.

I've done this on a number of engines that have lain idle for many years, and it's always worked fine for me.

Hello there , your answer was given partially correctly .

Remove spark plugs , add a SMALL amount of engine & diesel mix via plug holes . Leave plugs out and turn engine by crankshaft nut for 10 -20 turns , after oil mix has sat over night .

This allows oil mix to seep past rings & lubricate piston skirts & bores . Once you have turned by hand , THEN use starter motor , this will eject any remaining oil mix . Refit spark plugs , a quick sniff of aerosol brake cleaner & fire that puppy right up . Petrol will most likely be stuffed and engine run like crap , just allow it to idle & warm through . DO NOT rev any more than is necessary to keep engine running

Turning the engine over by hand first seems an excellent idea. Might it be worth a quick look at the timing belt before using the starter motor?
