My car has not run right since I changed the termostat. I can't figure out
what happened. There is a gas smell in the oil now and it over loading on
gas and wont run. I can't believe changing the thermostat blew the car up.

You're right.. it probably didnt.

But I always noted that anytime you fix something under the hood, there is a
ten percent chance somethnng else will immediately go wrong.... even if
you're sure you didnt touch it.
Sounds like engine is flooding, barely running. Raw gas WILL get in oil.

Black smoke out exhause too? FuelPressRegulator leaking?
Maybe Stuck injectors?

And WHY did you change the thermostat in the first place..overheat?

It was only running about 195 but with this old of a car I like to keep it
running at about 180

Heh!

Take that back...MAYBE you did cause that.

If the problem seems to be cumulative, meaning it didnt show at first, - AND
it starts well enough when cold- your engine is maybe not getting up to heat
enough, assuming this is the 1st gen EFI system. Combination of engine
coolant temp sensor marginal.
MAYBE
Your ECU never goes into closed loop and always runs rich... the EGO sensor
never looked at because it's always warming up.
Just a wild guess, like I say and would require some other marginal
components, too.

BUT!
There is NO reason to lower the engine temp!

Causes increased oil sludging, and MAYBE what you see there.

my husband is suggesting that I change the whole car over to a carb but I
can't even think of all the work that is in changing the intake and
throttle body right now since I don't have ant other wheels.

Don't think a 180 deg thermostat will let the computer go 'closed loop'.
I'd put back a new 192 (or 195?) thermostat asap... if you lucky, you
won't have to do a catalytic converter as well.

Good Luck!

We once changed wiper blades for a lady. When she got home she
called and asked what we did to her car that the RR window would
not go up? She insisted it was our fault since we had the car in
the shop. We fixed the window at not cost. I don't know how
many times we gave away free batteries to customers who
complained that
it went bad right after we worked on their car even though the
work was not related to the battery. Is is all a cost of doing
business in the modern, it's not my fault world, I guess. LOL

I planned on changing the thermostat back and changin the car over to a
carb if it can be done easily.

That is a terrible idea with an efi car. The car never gets up to
temperature, never goes into closed loop mode, and the computer keep
injecting too much gas becasue it thinks the car is cold. Change the
thermostat back to what it is supposed to be. A 180 degree thermostat wasn't
a good idea with later carbed cars either. Why do you think it is a good
thing?
