manifold bolts keep coming loose

[lcbandit]

hi

my bolts keep coming loose on my manifold, im now on my 3rd gasket, is there anything i can do to stop this happening, (only checked em a few days ago but then came loose within days) seen something on one of the threads that looks like it locks the bolts down but when i try n explain to garages etc what i need then dont have anything (or dont understand me) tried to copy a pic of it for this thread but it wouldnt do it. Gonna take bolts out to make sure they are long enough too.

thanks

what manifold, the inlet or exhaust?
Have tried replacing the bolts/washers, have you tried using locking nuts?

hi sorry not been too clear the exhaust manifold where the turbo bolts on, no nuts on em just bolts and they are new bolts n washers

RS Components do them quite cheap

 

[lcbandit]

ok cheers will try them, hope they do size i want, need 17mm i think

 

[Damoegan]

17mm washers, you sure!!!

 

[lcbandit]

probably not lol i use a 17mm socket to tighten the bolt up but don't know the size of the thread

 

[Damoegan]

17mm socket will be a M10 bolt/nut....

 

[chrisbond69]

yes its a m10

 

[lcbandit]

ok so in english whats m10?

It's the thread size...

Use some loctite or something or you can get nuts with locktite at the end of them.

Use some loctite or something or you can get nuts with lock tight at the end of them.

No, don't use any sealant on manifold to turbo bolts, really bad idea!!!

 

[Ibiza-Tint]

How it on the outside of the turbo, Its not near any internals...

So you think the exhaust manifold and turbine run cool?

 

[lcbandit]

thats why i havent used locktite or exhaust paste as someone suggested! n i sort of realise that m10 is the thread size but in mm is what i meant or is it 10mm? ive been takin bikes to bits n puttin em back together again for years but only ever gone on head size if you know what i mean

 

[Damoegan]

Yes, M10 is 10mm.

17mm socket will be a M10 bolt/nut....
