Start up after years unused.
I have a 1998 c70 t5 auto petrol (88k) that has been sat for over six years and I'd really appreciate some advice before attempting to turn the engine over.
I've installed a battery and have got a bundle of data from the motronic (4.4) using the '850 obd-II' app and I'll decifer that first to see if there are any error codes. Assuming that is ok, and all fluids, belts are ok, should I turn the engine over manually a few times first to help distribute oil that has settled? Is fogging oil in the cylinders a good idea? I've never worked on a engine with a turbo before, is there something I should consider there? The petrol gauge is right at the bottom, so I'm planning add fresh fuel to dilute whatever remains. The only problem that I know of before she was parked up, was a parasitic drain on the battery, which I'll obviously need to address if I can get her running. Any advice would be much appreciated. |

Fresh fluids/belts. Most things should be fine, only if the brakes are not seized on, consider yourself lucky... might be precautionary to spin it over without plugs for a while to move oil around, then plod on.
Depending on how old the fluid was when it was left, brown/black now?? I predict 1-2 calipers, maybe the MC, and perhaps the ABS unit. Still 'amberish'? You'll get away with it. Fluid goes to acid pretty quick, and if it's not been moving, brake systems won't tolerate it. Definitely, definitely don't push that pedal too far down!

Thanks CNGBiFuel, much appreciated. I'd fitted a repair kit (inc pistons) to both front calipers not too long before she was laid up and bled quite a bit of the brake fluid at that time...it def looks amberish so I'm hopeful on that score.

As CNG above.
Definitely fit a new timing belt as the current one will be 'set' Drain the oil - I would leave the plug out overnight - and change the filter. Remove the spark plugs and put a teaspoon of oil in each bore and remove the fuel pump fuse. Spin the engine over on the starter until the oil light goes out. Replace the plugs - preferably new - and the fuel pump fuse and try to start it. Once you have it running and ready for the MOT, change the oil and filter again and you should be good to go.

Some sensible advice above… However spinning it over on the starter is a definite NO NO if it’s sat for that long.
ALWAYS!!!!! Turn an engine that’s sat for years over by hand first!!! Get a socket on the crank pulley and see if it turns with the plugs out.Diesel and Atf down the bores .

Thanks for that rudi, I'll definitely crank it by hand first. Can I ask what you mean by Atf?
