just bought 98 itr for 3-4 months now. found some kind of oil under passenger carpet. don't know where it's coming from. might be motor oil spill from previous owner, but no sign of oil spill from top of the carpet. oil soaks only underneth carpet. if anybody might have an idea. let me know, thanks.

 

wow...

 

I have no idea how oil could be comming up from underneath the carpet unless he spilled oil and put the carpet back down. I am going way out on a limb here, but is it possible that the a/c system is leaking and its oil somehow dripping down the inside of the firewall and into the floor pan?

 

I have had oil in my passenger side floor before And everywhere else for that matter.

Any chance you have an oil catchcan on the passenger side of the engine bay? Check to see if it ran down from the firewall somewhere..

Previous owner may have had an oil pressure gauge too, a mechanical one that leaked.

It seems more likely that it was spilled though, and after time just settled to the bottom of the floor.

Are you sure it's oil? Another possibility is that the drain tube for A/C condensation is clogged, which would make water drip onto the passenger side floor...

 

r134a is mixed with PAG oil so it's a possibility if the evaporator unit is leaking.

Check behind the glovebox to rule out the a/c system that's leaking.

 

yeah sounds like it may be the a/c unit

 

im not sure it's oil, but looks like, greasy like, doesn't quite smell like oil but might just be old oil. no leaks form anywhere. looks like oil is just sitting in one spot. maybe 1 square foot. no sign of flowing or drips from anywhere. i'll just have to talk to previous owner.

 

What color is the oil, is it dark or more of a clear type oil, I would suggest the a/c oil is getting in some where.

 

it's dark oil

 

it's dark oil. it's not as dark as used oil. but not as light as new oil. it's in between. how does ac oil look like
