Stuck motor

Hi guys
So I did a rebuild for my CA, New rings and bearings, motor turns well if i torque the main bearings to correct torque setting, then I started with the bigends, everything went well till I got at No4 bigend, the the motor would turn, but very difficult, put it in the car, motor is stuck......

Any got a Backyard solution? can I pull the car in gear? trying to free the motor? Really want it to be running at japfest.

Motor is going out after japfest again!

Any help what so ever will be appreciated! thx guys!

Normally when a motor is stuck there is water or oil or something in the combustion chamber....take out all the plugs if any is in and try and turn the motor by hand...see what happens.... is your clutch ingaged somehow...is the car being able to move without the engine turning when it moves?

I know I sound like a dumbshit....which I am....just thinking with the little brain sells I have 😳

I have checked the cyl before fitting the head, was dry as a bone, clutch works fine, I cant turn the motor by hand, tried a few times yesterday, thats why i wanted to pull it to try to turn it, I am just very desperate now!!!!

if you desprate then just start it

after all its comming out and you will have to get your na motor or SR20DET

Well, only one little problem, starter doesnt want to turn it... If I pull it, the wheels one lock up...

Sure about your bearings are the correct size and is the torque wrench not fuct

Yep, checked old bearings, and its a new torque wrench...

What if i pull it at 100km/h and put it in gear and drop the clutch? 😛

Well im not sure about youre problem, but one thing is certain , what is not broken yet, is going to break if you keep on going at it in this way :!: :!: 😮

yeah that i pretty much can guarantee, but what if it works? 😛

You should get some noise from it doing that but that will be the end of it

what are the bits You replaced

new main bearings, new bigend bearings, new piston rings, do not understand why it will turn Wednesday night, but not yesterday?!

Get the crank re mic'ed and check bearings...

he has one day

just do what you want peg 100kph and drop clutch will give nice smoke show

look, this weekend I want to use the car for japfest, The motor was turning when I closed up the bottom end, put it in the car, and it decides to stop, I thought of putting a bit of oil in each cyl, taking out the sparkies, and pull it, just to free it, obviously not at a 100km/h

And I am going to take the motor out completely after japfest, doing my conversion then

peg to me its the drive train that causing it or

your piston to head clearances are not righ so the piston is hitting a vaulve or somthing

can it turn backwards

or like draco said is id not your drive train causing the crap

or you never droped a socket down the spark plug hole haha

clearence wont be a problem, checked everything beforehand, If I put the car in gear, press the clutch, I can push it round, so dont think so, cyl is clear, as far as I know... piston 1 & 4 is top, 2&3 bottom, checked 2 &3 before putting on the head.

Turning it reverse.... releasing the bolt on the front pulley.... so ya.... not nice

like I said the motor(without the head) Turned on wednesday evening, after assembling everything, its stuck.

loosen head bolts and try again and see

dont see how that will make to big of a diff, tried to turn it before torquing the head... thought the starter would be able to turn it

Think man think !!!!!!
