well finally i have got my engine back together with all new parts.
went to put water into it today, and it seems to have a HUGE amount of pressure coming out the radiator filler cap.
To the point where i cant actually fill it up, and it steams so much!
Its a 2-LT(1)
Does this mean my head gasket hasnt sealed properly?
rebuilt engine, steaming lots...
Re: rebuilt engine, steaming lots...
am i understanding this right you filled the cooling system with water and when you start and run it there is alot of steam coming out of the radiator
my 4wd is not a truck

Re: rebuilt engine, steaming lots...
not the radiator but the filler hole where the cap goes on.
heaps of steam after its warmed up, so much that its hard to fill it all the way up, and i think i stopped after abour 2 liters of adding watter and shut it down

Re: rebuilt engine, steaming lots...
was the head crack tested?
Never argue with an idiot, they drag you down to their level then beat you with experiance!
Re: rebuilt engine, steaming lots...
head is a brand new after market head - i think made by kiwiheads? It was used before, the engine spun a bearing which is why it was rebuilt. I think the head had done about 3000k's since it was new.
Today I will back off the headstuds and retorque them after draining the water again and see what happens.
Will use a different torque wrench this time to be extra sure...

shroom, please don't be offended by any of my remarks, I'm a grumpy old bastard after a big weekend 
. Have you RTFB ( read the f#cking BOOK ) 
. If not I suggest you do, first off why are you running your engine while trying to fill the cooling system ? . Without getting my workshop manual out I am not sure the exact cooling system capacity but at a guess i would say 4/5 liters and If you can't get that much coolant in before you start there is something wrong. You say 2LT motor---- is that a 2.4lt Diesel Toyota 2LT ? if so there are different head gaskets for them, make sure you have fitted the correct one. Now I am trying to rack the old brain here, on these motors I am sure the Head Torque is set by angle torque, where you torque the studs down to a given torque of say 45lb-ft and then a further 180deg, once again RTFB. Some engines have a cooling system bleed bung fitted at a high point in the cooling system to be removed while filling to allow the air to get out that stops the water from getting in. Fill the system before you start, start and run at fast idle with the heater's turned to hot till you feel the thermostat open and the hot water start to go to the top tank of the radiator, run till normal operating temp is reached then turn off wait till it cools down then check water level and top up if necessary.

Re: rebuilt engine, steaming lots...
no offense taken...
have read the workshop manual i have here - and ive done this before on this truck about 5 times without any issues.
Studs were torqued down correctly, and the gasket was supplied by the people who rebuilt the engine, so im guessing they have given me the correct thickness - can confirm this with them but i assume its rare they supply the wrong thickness.
Yes it is a toyota 2.4Diesel Turbo (2LT) roller rocker type.
Will re-read the manual on torquing the headstuds, but i might replace them now as its the 2nd time i will have torqued them and they will possibly have stretched now.
cheers
