Help overheating

[lukey4x4]

Hi all more problems , my vit engine is overheating after bout 20 mins with the fans turned on with steam and watwr coming out of a llittle hole in the rad bottle , my temp gauge not working so not sure how hot it is but i can smell it and the rad is way to hot , and because i have the vit clocks in my sj a orange check engine ligh came on and wouldnt start for 10 mins after , took it to a garage and said possible head gasket because it had cream on oil cap ,he did no pressure test so think he was guessing , engine has bin sitting for a few year so i thort could be condensation ,any 1 got any ideas thanks

Cream in the oil cap could just be from short journeys as condensation can build up.
If its really really overheating though and the headgasket is busted, you should either see bubbles in the radiator (gasket split between cylinder and water channel) or oil in the rad (split between oil and water channels)
However, usually when its split between the water and cylinder it will usually burn water and chuck white smoke out the back.
Are you getting smoke?
Also worth revving it up with the radiator cap off to see if there is good water flow.
You could have a crappy water pump or blockage in the system somewhere.
Have you tried draining and refilling the system? Just in case there is an air lock somewhere. Always refill with the heater set to HOT

Do a compression test on your cylinders, that should show up a head gasket problem,

There are videos on YouTube of how to do this

White smoke? A new Pope? No, no, no... White smoke from the exhaust means steam and this steam is generated by temp and water. So, I would say head gasket and/or a tornt head I'm afraid....

It looks that way mate gunna get it pressure tested at weekend n hopefully get it sorted soon thanks

Does the white smoke linger in the air or dissapear fast? .. is it like smoke off a cigarette or steam out of kettle? As white smoke on startup is just worn valve seals. Comp test like the others said is the way to go.
