Question about 1994 Toyota Camry

1 Answer

I have a 94 Camry with 150,000 miles. The engine was getting hot, but not overheating. Running like ****. Was going to replace the head gasket and found grooves in one cylinder. So I decided to rebuild the engine. It ran great at first. After a couple of oil changes it started to develop sludge. At one point it was so thick that there was no oil on the dipstick. The oil seemed to be staying in the upper half of the engine. Ran engine cleaner through it and drained and repeated several times until the oil looked right. Was good for awhile and now it is sludging again. Idles ok. When put in gear it runs horribly. Any thoughts or suggestions?

    What does that mean that the rings washed out and never seated? What has to be done now?

    the normal process for new rebuild is with non detergent oil and to let the rings seat means they scratch a home in the cylinder walls.....if that doesnt happen they never seat or seal against the walls or 'wash out' ....the rings are shiney and so is the cylinder and oil slides past ..you need to hone the cylinders again and reseat the rings after cleaning them thoroughly...good luck

Car overheating replaced everything and still overheats


try a pressure test on the radiator while it engine is running.. If your head gasket is broken the compression of the engine goes into the cooling system. If the pressure rapidy increases it would indicate a head gasket problem.

94 camry xle 6cyl changed thermostat changed hydraulic fan new radiator cap and new coolent and it still overheats once the guage reaches a little over half way then it gets hot real fast what do i do


Softly418 had this problem...........

This could result from a thermostat which is stuck closed (but you have a new one), or a failed coolant temp sensor not allowing the radiator fans to run when they should, but I think you have a blown head gasket. Overheating is a classic sign of combustion gases getting into the coolant. The pressure also forces it out of the overflow.

Warm up your engine a little, about half, and remove the radiator cap by putting a towel over it first. Then let the engine keep idling until hot while you look down the filler neck into the radiator......carefully.

If you see white bubbles like dry ice, that is a failed head gasket. If not, have a mechanic do a test for combustion gas in the coolant with a gadget like this

Hi i have a 94 misubishi exspress van 2.0litre motor i brought it with a blown head gasket i had a mechanis pull head off had it tested and ithe head was no good now replaced with brand new head mechanic...


Yes, it sounds like the water pump or radiator is bad. And the car overheated in the first place, which warped the head on it. It is an aluminum head and if it gets too hot for very long then it will give somewhere. And that is what you bought. Or when the head warped, the engine did to. Or it cracked, and the antifreeze leaked into the cylinder and you leaked antifreeze there and overheated now. But it should have had steam coming out of exaust. Or running bad, missing? Did yoy have the water pump replaced?

Or he could have put the gasket on backwards and it blocked off one or two holes that the antifreeze travels through to cool that head and the intake.

I hope this helps.

1996 acura 3.2tl replaced hose on back of engine replaced thermostat,replaced radiator,still running hot might run fine for week then run hot brown gunk in radiator.need help.thanks


Brown gunk is either oil from a blown head gasket or 'stop-leak'. The head gasket is expensive to fix.

If you have over 150,000 miles probably cheaper to replace the car if the head gasket is bad.

Oil mixing with coolant.Car is overheating, coolant is tan.Had radiator tested.It's not trans fluid.Oil level fine and no coolant in oil.Oil on top of heads look fine.Buick park ave 150,000 miles 1998...


If this is a 3800, Upper Intake Plenum or Lower intake gaskets are an inevitability. Head gaskets on these engines rarely go out! Seriously, don't get duped. I am doing the job on my grand prix right now. Google it for further explanation.

1999 GMC Jimmy Running Hot w/ Engine coolant reservoir empty


I guess the burning question is , where is the coolant going.
Is this a 4.3 engine? How many miles does the vehicle have?
Has the intake gasket been changed?
I'm guessing a can of "Bars Leak" may cure your problem.
Let me know.
