my v40 leaks a lot of oil . i got my timing belt replaced and the next day i was coming home from work and oil light came on and i stopped about .5 miles from my home got a quart of oil put it in and got home. when i got home oil light came on again . i asked my neighbor who works on cars to look at it and he told me that it could be the oil pump. then he looked at the timing belt and said "Cam plug"or"cam cap" is missing. could it be the cap or plug he is talking about? if so where do i get it from ?
thanks

Have you tried bringing it back to whoever did you timing belt, to check if they have missed anything?
