How do i fix a oil weak on a 89';chevy 1500 p/u ?

I always use Lucas oil treatment to stop most of my small oil leaks. I have always had good luck using it.How do i fix a oil weak on a 89';chevy 1500 p/u ?
Where is the leak and how bad is the rate? If it's not a puddle maker just dampening areas I've had great luck since switching to Valvoline Max Life especially if it's a high miler. If you have a mechanical aptitude you could replace the leaking gasket with simple hand tools, unless it the rear main which knowing that era of Chevy it may very well be, then professional help sould be sought but that should be a 1 piece seal so it's not that bad with a 3 foot extension and a tranny jack you should be able to rent.How do i fix a oil weak on a 89';chevy 1500 p/u ?
didnt say where it was leaking but most are easy fix if like the upper engine gaskets so where is the oil coming out at that would help
Replace whatever gasket/ or seal is leaking; most are easy. Its the rear main thats a pain.
One thing you could try is a product called stopleak. Just add it to your oil and it will seal any small leaks and cracks in your system.
