1991 Toyota pick up gas odor

My '91 pickup has just developed a strong gas odor. It is only noticable when the truck has been run for a while, and then it is very strong, both inside the cab and outside the vehicle. If the truck sits for a while, the odor goes away. I have looked in the engine compartment, but cannot see anything obvious, and frankly I don't know if I am looking in the right places. Mine is not a gas smell as such. It smells for likea combination of exhaust and gas. I have check the exhaust system and nothing seems loose. Could it have something to do with the catalitic converter? I have a 91 4 cylinder 4x4.

Check if the cadillac converter gaskets are good and tight and no holes in it if all good it might be worn out thats a gasy smell when it runs, and if it sits it will go away

also check no oil is leaking on the exuast from a oil leak as such ,

well depends how strong you are, and if you are using a car lift or doing on your back. either way drain the transfer case fluid, should be bolt on bottom, otherwise when you seperate the transfer case from trans there will big mess. take transfer case off first note how it is mounted with paint marker and then take trans out. much easier then leaving together.
