intake Manifold screws
i have a toyota Siena 2005 and i'm trying to remove my intake manifold so i
access to my rear spark plugs so i can replace them.
i need to remove the 4 hex screws on the front of the manifold that connects
upper intake to the lower. My problem is that one of the bolts head broke off
was unscrewing it because it was really tight. Does anyone know how
i can get the rest of the screw out so i can replace it? Does anyone know how i
should remove the other 3 bolts without them breaking off on me? Should i put
flame to them and heat them up? your comments are welcomed
Soak them in PB Blaster or Diesel fuel overnight and then slowly try to turn them back and forth you may have to keep soaking them as you get them too move, then drill and tap the broken one. When you ready to go back together use stainless steel bolts with never seize on the threads. And yes this is going to be a pain to do.
there are tools for the job you describe- but here is a thought- get a professional to do this work- see what happened when YOU tried doing it? It can only get worse-
You might need to use a bolt extractor. Search youtube for vids on using bolt extractors to remove broken bolts or studs.
