So after a 30 minute drive, I finally reached home. As i was parking, thats when my thermostat gradually went up. I just recently changed the head gasket last week. I checked my oil and coolant; they were good. After a few minutes of driving, my idle would always drop from 1000 to like 300. I started my car again and there was a whole lot of white smoke coming out from my exhaust. It only came out when my car was still pretty hot. After about 15 minutes, I started it again and not much smoke. Within the next hour, no smoke. I found that i was leaking oil from my valve cover gasket and valve lash was ticking loud. I already adjusted the valve lash. Any of these the reason why my car's thermostat gradually went up or caused the white smoke? If not and its something else, please help me.

Need More Details
What Was The Reason You Changes The Head Gasket?
When You Changed The Head Gasket Did You Change The Thermostat, Sensor?
Did You Have The Head Checked For Warpage?
Does It Smoke Contiuously, Start-Up, Or Both?
Having Bad Valves Has Nothing To Do With Water Getting Into The Cylinders.
Oh And On Your Idle, Could Be Something Complicated Or Some Thing As Simple As A Bad Ground. -
Are you sure it's 300? That first line represent 500 rpms. There's no way (short of external equipment) to measure an idle that low.MRT
37.5 MPG, AC on, cruising at 80.
30.0 MPG, AC on, aggressively driving around 90.
27.5 MPG, no AC, cruising at 90 with occasional gridlock. 40 degrees Fahrenheit

I think you might be about to gain some more experience in head gasket replacement. It might have been a freak occurence, but somehow, you got water in your exhaust if it was truly white smoke.Comment

I changed the head gasket because it was blown. I had coolant and oil together. I did not change the sensor but my sensor is still working fine. I only had smoke after a 30-40 minute drive from school to home with slight traffic.Originally posted by Zeusimo View Post

someone told me that it could be air in the cooling system since i didnt bleed it. could that be it?Comment

Compression test.
Was the head torqued to spec. and in sequence???Comment

general rule of thumb:
thick white smoke = piston rings. but it will do this all the time, not just cold/hot
light white smoke (also known as cold smoke) = condensation. engine is normal
blue smoke = oil being burnt through the combustion chamber.
black smoke = timing is incorrect. cheap 87 gas and timing too advanced.
The past, to present.Comment

did you check the head for warpage when you had it off? because if the head is warped the gasket wont be able to make up for the differance and make the engine smokeComment

just found out that my new head gasket is leaking. did not check for warpage. and i did torque the head down to torque specs and sequence.
could steel seal or some kind of liquid that we pour in the radiator help stop the leak?Comment

Have The Head Checked For Warpage, If Warped Machine The Surface, New Gasket, And Torque To Specs In Sequence.
Those Radiator Addatives Don't Work It's Just A Way To Get Money From Lazy People.Comment

and you made sure you installed the HG correctly? There's this one oil pressure hole in the back that you need to set the HG on, if you flipped it then that could be why its leaking oil and sending coolant into the wrong passages.
