So i gat the cylinder head from the rebilud and needed to get them back on.
as we started to close the bolts whit very low presure.
i didnt get to the torque meter even.
The scrowing from the block snapd.
avry bolt i sterted to tite the scrueing snapd.



Any idea what next?
and how can this happen?
Jast to be clear.
The bolts are new oem
Thitning in the rgiht order.
avrything like in the manual. And i didnt even get to the first turqe tight.
2 in each head alredy snapd. 4 in total
My gess thet all 20 of the bolts screwing will snape if i will try to close them.

 

Man I am so sorry to see all that damage!! Looks like the bolts are pulling the Aluminum threads out of the block?
I can only suggest using Heli-coils in the block to give you steel threads. I have never seen threads pulled out so perfectly?

Seems thet will be my only chance.
but the threads are so deep in the engine block...
and so littel room to work in...
Is it possible?

 

Well Heli-Coil is only one of several thread repair systems. I do think Keenserts are better but it's up to you.
Take a look. I would send them an E-mail with your pictures and a description of your problem.

Has the engine been subject to an overheating episode ?

 

tank you so mach it will be very helpful.

 

yes it did.
profesional says thet to the overhiting gat the threds twisted.
i will get the block out and send it to profestinal to chack the block to see if there is any other damage.

 

If the block is distorted due to overheating, it's better to simply install a used engine.

 

Normally I would agree with you on this solution but Udiasi's location means finding a used engine will be difficult.
