Oil leak

[hiperf406]

I have a oil leak on the passengers side of my 91 ZR1, when I start my car there is a oil burning smell. The car sat for 6 mo & there is a fair puddle under the car. I don't know if the cam covers have a gasket in them or not, if so is it a big job to replace .TIA.

other things it could be is the oil pressure switch,either the top one or the one thats a pia to get to on the bottem side of the oil filter housing or the oil filter housing gasket itself as well as the lines to the oil cooler . you need to take your time with a good light and you should find it .oh one other common area is the oil pan bolts have a tendancy to be loose .hope this helps

I'd suggest starting with a check of your exhaust manifold studs Lorne.

My bet is on the Oil Cooler Hoses.
Check where the metal portion is crimped to the rubber part of the hoses.
If your finger comes away wet, there's your smoking gun.

Sounds like oil cooler hoses to me. I had the exact problem. Good luck changing them. I don't there is any way you can change those without making a mess, no matter how many rags you use.
