It should worry you man. . There will be a stream of oil. An oil leak can come from anywhere. Just cause there's no smoke doesnt mean the engine is A1. If your dead set on this teg get it looked at by a qualified mechanic.

My friend bought a R32 GTR. The seller said it was oin good nick. HOwever the oil pressure gauge was BELOW average. Seller said it was malfunctioning. He had a look around the engine bay. No oil leaks. BUT WHAT HE DIDNT KNOW was a sneaky bastard had cleaned it all up.

Couple days later spun a bearing. Couldnt afford rebuild. Sold it for peanuts.

It's a jungle out there my friend. Be very very careful.
