Hi, i'm new here so imma post my problem...

All engines coolant is leaking from a bolt, which bolts the lower inlet manifold to the cylinder head.. whats the most probability?

Cracked cylinder head, cracked inlet or worn gasket? i am really hoping it's not a cracked cylinder head :(

i really have no idea how it happened

i do not have a picture of coolant leaking from the bolt.. but i can tell u it's a lower bolt of lower inlet manifold.. water is coming from behind the washer :(

it can barely be seen, the bolt goes exactly over those 2 hose pipes under the lower inlet manifold...

what i was gonna try to do was change the bolt 1st see what happens, next remove both upper and lower inlet manifold, ( check for gasket or cracked manifold ) if i find nothing i will have to remove engine to check for a crack in the cylinder head.. :((

Any expert ideas would be great, thanks

Is it closer to the front? If so, there is a water jacket under there that one of those hoses connect to. The sealant might have gave out. Not easy to get to with the intake in the way if it's the stock intake.

typing about it on forums and taking pictures. Hoping someone guesses correctly WON'T FIX IT. Start taking it apart and see what the problem is.

Yes when I have time I will try to take the whole intake manifold out and see what happens, probably leak will come out from the hole where the bolt goes in , will keep u updated

Btw mine is a stock intake, and looking to change it, from where can I find 1? If u got a link pls post me 1 thanks

No need to change it unless you have bigger cams, turbo, injectors, tune.

I got standard cams and turbo, but pistons cp, 550cc injectors fc power commander stainless exhaust and tuned , 325bhp s14 so a new Inlet manifold would be nice hehe
