Does anyone know if that hidden allen bolt on the intake manifold needs to go back in? I just took my intake manifold off and unfortunately it got a little mangled because it was B** to take off.. I don't want to put it back on my new engine if I don't have to. If I do have to put it back in, do I have to torque it down, or can I just tighten it enough to where it won't come out??

 

this is worth only about $.02:

unless you like doing things twice, take that bolt while you have it in your hand, get a match for it, and put back in there with the appropriate tool to torque it to spec.

if you have to buy an allen head socket to do it, instead of just an allen key, take advantage of the cheap chinese parts available at the local store, and buy it. surprisingly, Lowe's has a good selection of metric hardware.

the end result is a feeling of satisfaction that you eliminated that s.o.b. old bolt; vs. the feeling of worry that some day you'll have consequences from the shortcut. i hate that feeling. you know "Murphy" loves giving people that feeling.

 

Very good advice here.

Your dealer could get that bolt for you for around $4.00. Four bucks is not worth having a leaking intake manifold.

 

i made a very simple tool to deal with these bolts regular 6mm allen wrench. Cut the short end off .

Braze long end into 6mm1/4" socket then get a male 1/4" to 3/8 female adapter braze that I built this about 18 years ago .

I still use it when I need to.
