Manifold Fix

[swooshdave]

 

When I was balancing my throttle bodies someone, probably docc, said make sure they aren't stripped. Of course they are. As I'm not a fan of the Helicoil I'm fixing it once with Timesert.

 

 

Step by step to follow.

TimeSert is a great product.  E-Z lok ( Fastenal ) is a great thread repair too .

How does timesert differ than helicoil?

It is a threaded "sleeve" as a Heli-Coil is like a spiral wire .

One can fail from repeated use. One cannot.

There are a lot of aluminum engines that come with Heli-Coils installed in every threaded hole.

If it was a part that never came apart it would be fine. But spark plug holes or these manifolds are constantly being used so the failure rate will be higher with the helcoil.

I stopped taking a plug fastener in and out of my intakes for throttle body balancing after I stripped one and returned to the brass taps and rubber caps.

I undid the 4 screws holding the TB. Two on top, two on the bottom. I'm taking the TB off so I can clean out out any debris from the operation.





Using the supplied drill open up the hole slightly.



Using the supplied countersink drill.





Using the supplied tap thread the hole.



Screw the insert onto the installer tool. Be sure to use a little oil so the insert comes off the tool easier.



Screw the insert in until you feel resistance. Then keep going. This expands the insert and locks it in place. Then unscrew the tool.



Finished fix.



Vacuum and clean out the manifold before reassembly. You have now permanently fixed the manifold. As they say repeat on the other side.
