What’s the process for retorque after 1000km? Can I use torque only or it needs to be angular?

[@abcautotrendy]

Its the process to fist check whether any changes of the valve clearance, then check the last step of the torque settings

Hi, head and head gasket have been previously changed a couple years ago but gasket has blown again... why is this? I'd there a permanent fix for this problem or do they keep blowing?

[@abcautotrendy]

Hi, well there will be an issue to blown the head gasket.. please have the following check * using the correct radiator cap -* using the correct reservoir tank cap * if the water fan replaced along with the head gasket replaced? Are you using the torque settings to tighten the gasket?

[@romeovego3085]

Hello! Thanks for the video. may i ask if a cracked cylinder head can be welded ? My D40 head has 2 cracks in the water jacket. Thank you.

[@abcautotrendy]

It can be done ✅ but not highly recommended to do so as specially Navara heads are so delicate… if you do so so many precautionary care to be taken

[@johnshiny6283]

hi do I need new head bolts for head gasket replacement?? or use it again?? thanks!?

[@abcautotrendy]

Nope, you can use the existing bolts

[@johnshiny6283]

Hi , i have nissan navara d40 2.5dci , i had problems with warming engine temperature, , i sent the car to the mechanic, hi said it must sanding the engine head motor , but if you want garantie , you must be sanding the engine block too and pistons too , is this correct?

[@abcautotrendy]

That is absolutely correct dear

[@adic63]

@@abcautotrendy thank you very much ✋🏻

[@abcautotrendy]

Your most welcome dear

[@adic63]

@@abcautotrendy one last question please , if we surface engine head , engine block and pistons , will engine work good, without any ticking or something ?

[@abcautotrendy]

Well, there is a maximum limits to surface engine head and the block..so you have to inform the lathe workshop technician to be causation about that… They only can let you know whether the head needs to surface and valve (intake and exhaust) needs to be replaced, valve guides needs to be replaced along with the valve sheets With regards to the engine block… they will update you whether piston needs to be replaced and if so the bore also needs to replace with sleeves.. If there is displacement in the piston bore, the stroke ratio differ so in that case it’s a mandatory replacement

[@adiadrian1758]

Hy do I need to change the head cylinder bolts after I removed the cylinder head ?

[@abcautotrendy]

No dear, your not supposed to changed unless broken or something

[@negueba235689]

@@abcautotrendy Some engine its strech bolts and they need to be replaced everytime you undo them. But the YD25 dont have them ?

[@abcautotrendy]

@negueba235689 its depends, you need to inspect the thread on both the bolt and the head before tightening them | so better to use the correct torque wrench with correct settings. In case if the thread has been damaged you may need to insert either helicoil or customize helicoil
