Is it safe to run 9 out 10 exhaust manifold studs?

[Vangpride]

Right now I have 9 out of 10 due to one that broke. I'm going to get the head fixed but jw how safe it is.. Thanks for reading and anyhelp is appreciated.

i think as long as it doesnt leak, it should be ok for now ?


Napa could get the manifold stud in 1 day. i got mine from them set of studs and nuts for 20 bucks, tax included

Mines need to be redone. The head is messed up. Stud broke in the bolt hole

You could try using a bolt extractor, or if you don't have an exhaust leak with 9 out of 10 just leave it the way it is.

if its at the edge of the manifold, it might tends to leak, if its in the middle, i feel it should hold, as long as u drive it under 100km/h or 3k rpm ?

think most shop has helicoil, if they cant drill the broken piece out without hurting the thread, they can still fix it with helicoil

get it done asap maybe?

It isn't a big deal as long as you are planning to fix it, my car (when I bought it) and several others I have seen have multiple missing hardware on the mani.

So apparently my head is messed up. Im in need of either refillling in the aluminum block head and having a shop re drill or fix it. I also need a new turbo. I have not the slightest luck so far in finding a decent used one for sale and all the ones i see are sold. I dont even know how much people will sell heads on here for let alone ship it. I just dont want to buy a brand new head/turbo for $$$ when i can get a used good one for alot less... So anyone who see one please point me out to it. I need it ASAP. My MSP is running like crap. No power, struggles on the highway to hit 70mph and no sort of torque whats so ever.

I had 2 broken off but it never leaked. Even if it is leaking it shouldn't cause that much power loss. If your turbo is that bad off don't drive it, it can send metal and bearings into the motor

why are they saying its messed up?

They say the bearings might be bad. When I hit boost I hear like a flutter type of sound . I think the turbo is trying
To build boost but can't. I don't know . One tech helicoil 3 of them but they won't lock on tight..
The car is really weak and I drive it cause I
Have no car. :/ need help.

I try to avoid boost so I don't go past 3 k rpm and I make sure to
Not floor it.
