head gasket

Could my head be gone if after doing a compression test it was still showing good pressure? Also no milky oil

[LesterPiglet1]

No, what makes you think it has?

[gezo1234]

The car is overheating and all the sensors to the radiator have been changed and had a new rad in, also the car is not revin.

[LesterPiglet1]

Have you checked/changed the thermostat?

[matty101]

a wild guess, but the first thing that comes to my mind is the egr valve simply because it is involved in the cooling and the reving of the engine. might be worth taking it off and cleaning it. theres a guide in the FAQ i think.

like i say wild guess but since u've checked all the senosrs etc. mite b worth a go

[LesterPiglet1]

Yes it is a wild guess. The EGR will not cause overheating.

[matty101]

yeah it was, first thing that poped in ma head seein as its linked to bothproblems like i sed but hey just fort i'd chuck it out there lol

[gezo1234]

sorted the overheating, have blanked off the egr valve but engine management light is on, is it on because the egr valve is blanked off?

[LesterPiglet1]

Now that is weird. Never heard of the egr valve causing overheating before. Disconnect your battery overnight and hopefully the light will go off.

[matty101]

now that does make me feel smug

[LesterPiglet1]

And I am humbled.

the eml is on because the egr valve is not plugged in even if you have removed it the sensor on the egr valve still has to be connected to the engine loom to keep the ecu happy.....
