Problems lol

ok guys cars been running great till i left the cap of the radiator and boiled her dry fell like a dick lol but anyway car red lined on heat meter then shut its self off.

systympos now are
loss of heater in car
very rough idle
radator not holding water (but no leaks are found)

now i guess i have cooked the oil so i am going to change that anyother suggestions or question???

head gasket ?

 

[graham7773]

how long after it boiled dry did you put water back in? Too soon, oska is on the right track. The miss makes me think head gasket. Also there may be a cracked head or block. Any water/coolant/steam coming out of your exhaust. Any water in oil (milk coffee) or oil in radiator. More than normal condensation under the oil filler cap? all things to look at. Should have mentioned this earlier but a compression test will find a blown head gasket fairly quickly.

Fill the radiator with water, leave the cap off, start the engine and give it a bit of a rev. If it blows water out the radiator, she's stuffed.

If an engine has been cooked that badly to burn the oil, replace it with another engine.

Warped head/blown head gasket.

Bye-Bye Ecotec.

Once you cook ecotec's there f***ed mate. How didn't you notice the temp gauge skyrocketing

Because the temp gauge goes up when the water gets hot, but then it goes back down when there is no water to read anymore

Just replaced an Ecotec this week, exactly the same problem.

true But you can actually smell it when it's red hot and cooking itself..... not that i'd know

Just a question, would that completely root the engine? Just trying to understand how it would?

A number of things really....

1) Piston rings loose there tension from being so hot
2) Pistons can grab on the bores when overheated, causing damage to the pistons and/or bores
3) Oil gets overheated/burnt and can destroy bearings
4) Head and/or block can warp (block is an extreme case, but does happen)
5) Cracked heads and/or block.

Just to name a few really. But yes, generally it results in a stuffed engine.
