hi there looking for some advise is my type 4 engine seized. its a type 4 never seen it running its being out for over a year. tried turning the nut in the centre behind the grill but i didnt want to go at it full tilt. any advise would be much appreciated .
You could try taking the spark plugs out and give it a good dose of WD40 down each cylinder and leave it overnight. Then try again.
Or old diesel... When you say out...out of the van or out of the van outside etc? Do you know when it last ran? Was it sold to you seized? Is it a complete engine or are parts missing? What's the dip stick oil look like? Is there any in there? Is it free from water, it'll look greyish if there's water in there. Does the oil smell burnt? It'll turn over easier on that big nut with the spark plugs all out.
If it doesn't turn easily don't try. The rings will be stuck in the cylinder bores and unless there is nice fresh oil in there you'll score the barrels and risk braking the rings. If the engine is out of the bus take it apart and see what's what. It's an easy enough thing to do
