2003 Dodge Caravan Zero compression

Hi there,

You will have to do a wet and dry compression test.

Do the dry stet first, plugs out, full throttle and do the comp test note readings. Then squirt a little engine oil into No 1 cyl enough to coat the rings, then check compression, if compression comes up considerably the rings are worn (the oil will temperley seal the rings) if same or little difference valve problems are indicated or a badly burnt piston land. Do this for each cylinder, if as you say there is no compression, the car will idle very roughly and power will be down. You should not drive in this condition, get it checked and get it fixed ASAP.
