hey guys, this isn't about my soarer but my mates 91 V8 limited. i'll try and give you as much info as i can.
the car started to over heat on a long trip and had to be pulled over a few time to cool down and needed more coolant, now there is no leak so i figure it must just have had •••• coolant in it and it was boiling and pissing out the overflow?
anyway it got home just fine after some good coolant and drove perfect for a few days didn't get over operating temp once. then all of a sudden one morning the car would not start, its like the block is seized the starter motor is trying to crank strong but it looks and sounds like its trying to crank a solid item..
just not to sure what it could be, a mate had a motorbike once that we thought was seized could not crank the small bike with 120kg blokes jumping on the kick start it wouldnt even move and it turned out to be just a bent valve.
but if any of you guys could give us any info it would be greatly appreciated

Check to see if the Cam belt has broken ? The 1uz motors are a NON interference motor, so if it has snapped, you can simply replace it and start motoring again
Sounds like the head gasket may have blown and the cylinders or a cylinder is full of coolant (Hydrauliced on the coolant). Have you tried turning the motor manually with a socket and bar?

hey guys,
daniel yea mate we cheaked the belt, only took off the left bank cover so we didn't need to take the intake out but was very tight and looked in good condition.
stephen, no we have not tried that yet don't have the tools to do it where we are.
You could undo the sump plug briefly and see if any water is in the sump, it is heavier than the oil and will be on the bottom and run out first. Also if you have the tools pull the spark plugs out and see if it cranks. Hopefully it is only your Starter motor, how many k's on the odometer?
If you pull the plugs and you can crank the engine any coolant will be forced out by the pistons and you will know what the problem is. Lets hope it is something else.

hey guys, pulled the plugs this arvy and the 2 middle plugs on the right bank where wet so sure enough cranked it up and •••• loads of water shot out of those to chambers.
so would this most likely just be a head gasket, or head damage?
You wont know till you pull the heads off, depends on how well the cooling system has been maintained, good coolant and there should be none or very little corrosion, poor coolant could be the cause of the problem or the engine was severely overheated causing the gasket to let go.

yea hope its just a gasket to, but the car was running •••• coolant and did have a few over heating problems, so that might have warped the head?
is there anything i should know about these particular engines before i rip the heads off myself? or is it pretty straight forward?
I'm not great when it comes to this sort of work but i'm not bad i have done to whole engine swaps and other small work but the only head i have pulled off was on a 1994 falcon ute, lol
just don't want to start something i can't finish.
