Stripped Intake Manifold Studs

Featured Replies

1984 wagon, EA81

 

The studs which hold my carburetor onto my intake manifold are stripped. Can I just screw them out and replace them with new ones? And how would I go about unscrewing them? 

the head is stripped or the threads are stripped?

 

if the bolt heads are stripped, us rust prone northeasters deal with this stuff like all the time:


1.  use 6 point sockets - 12 points round stuff off

2.  use a metric or standard size socket that's a hair size smaller and WAIL it onto the bolt with a hammer - then remove them.

3.  use a chisel:
a.  knock a "V" shape into the edge of the bolt head oriented such that step B is aided

b.  knock the side of the V that will "unloosen" the bolt with a chisel

 

4.  grind, cut, drill the head off, remove carb, then deal with the studs

5.  weld a nut to the top of the bolt heads and then use a 6 point socket on the nut

no the threads on the studs are shot. I have taken the carb off and put it back on so many times that I stripped the threads on the studs that hold the carb on

Lots of us have the old spare box of nuts and bolts etc. from our parted Subarus.

 

I'll check mine later today for you. But likely you'll be heli-coiling those holes. Heli coils are great. But since this is regular maintenance for you I suggest to use a Time-cert or equivalent. Then you can simply remove the bolt and re-insert it plenty often like it was new.

Yes you can remove the studs that hold your carburetor on you will need a set of locking pliers / grips and a lot of penetrine or something similar.

 

Normally I use 2 nuts tightened together on the stud to remove it from the manifold but as they are stripped the locking grips / pliers will be your best bet.

 

They should unscrew with a bit of elbow grease, most people suggest warming the aluminium before trying to loosen the stud.

 

You should be able to find replacement studs in a good auto parts store.
