5.9 stock exhaust mainfold bolt

Hello all,

Week 3 of owning the R/T. Started making exhaust noise last week (Sunday). Started it up today and wow it was really bad on the right side. Parked it in the driveway, shrugged under the right, found that an exhaust bolt has rusted enough that it snapped off.
Are the bolts threaded into the Exhaust manifold, on the y pipe side or are they just dropped in from the top?


thanks all....

Also ordered my new front Timken Hub assembly this afternoon.

I felt around the top/header side and it feels like a square head. I just do not want to hammer up on it in case it is threaded.
A few pictures I have found on the web show straight holes, just wanting to check before doing anything.

Thanks all
Still reading posts here for my answer. Just finding MANY exhaust manifold to block bolt issues so far....

no they aint studs like Ford had they are just nuts and bolts dropped thru to hold the Y pipe to the manifold; about 3/8" X 2-1/2" long Its a PITA as its hard to get more tahn 2 hand in there but I put a flat washer under the bolt head and a flat an lock on the bottom side. I have an old distributor wrench that I can hold the bolt head with to tighten the nut wwith a socket and extension.

caution: still plays with carburetors!

Forgot to update this in case someone else searches later.
Yes they just pop out.
I used a compressed air can, upside down to freeze the bolt head, then pounded from the bottom with a 4# mallet.
I used a railroad tie that I had around the shop to extend up to the bolt itself.

Popped out after about 5-10 (heavy) taps.
