Hi there could someone give me any idea where to go next. last week the engine in my van forced the dip stick up and sprayed the engine with oil . took it to the garage the replaced the injector seals all seemed fine now it starts ok but when it gets warm after about 10 to 20 minutes of running it seem to cut iut when you try to re start it seem as though the battery is flat . leave it for a few minutes and it will restart as normal and run ok for a short while then the same again. garage said try a new battery but this seems ok when cold any help would be greatly received as i daren't go out in the van incase it breaks down again
