I have a 1994 Toyota Celica and the engine seems to get EXTREMELY hot!! Hotter than both of my other cars which include a 2002 grand cherokee and a 2005 Rav4. When I replaced the intake manifold gasket I could see a grayish sludge in the head where the coolant flows. The car does not overheat though. Could this sludge be limiting coolant flow? Will this flush out if hooked up to a flush machine at a local lube shop? Thanks for any help.

The other guy has a point it could be the head. But if the car is not using oil or anti-freeze then I would guess the catalytic converter is plugged up. Drive the car for a little while at night until you think it is hot then look underneath the car and see if the exhaust is glowing. And yes if the converter plugs it will glow red with heat. You will also notice a power loss. Good Luck

If gases and oil were getting in the water jacket you would over heat rather quickly and know it soon.
If the car had the original orange coolant in it this would be normal. The original Dexcool stuff was infamous for leaving white sludge in the bottle, heater core, and radiator.
Most people probably don't recall this problem but my dad got a free heater core and flush out of it when Chevy used it in the 1996 model Caprice. The original stuff recommended service every five years or 50,000 miles and of course since the cooling system is always neglected until it becomes a problem, this gave people a new excuse for not servicing the cooling system.
It will flush out with a chemical flush but really shouldn't cause too many problems for you.
Good Luck!

You changed the intake manifold gasket? Sounds like you need to change the head gasket the grayish sludge is most likely oil and water mixed which means you have either a bad head gasket or a cracked head.Most likely the head is aluminum which will crack if it gets to hot and chances are it already has don't drive the car until you can have it looked at or you will risk throwing a rod

autos are like human beings and mechanics ought to be reported as quite vehicle medical doctors yet without Q+A i will attempt to assist this is a ninety 4 so the matenence may be something to look at if the radiator is even grimy on the exterior it won't help and correctly how approximately changeing the fluid in the radiator no longer a lot of human beings try this and it is going to be finished each and every 365 days, if no longer it has a tendency to start depositing impurities on the interior purely as oil that's no longer replaced many times. My suggestion in case you like could be to empty the fluid and verify the outdoors and blow it clean with stress water and or air watever you are able to and if that doesn't make a distinction have the thermostat checked.additionally a unfastened or broken belt would reason issues like that expensive.
