So my car is currently in the garage as its making a clicking noise when you start the car. (ONLY WHEN WARM)

The noise goes after 30 seconds or so.

Now I think its the TCT which needs replacing from reading the forum, but i dont want to go to the cost of buying a new TCT to find out that it does not solve this problem, any recomendations?

Thanks

Alex

 

i've seen posts on hear about sand blasting the worm gear inside the TCT.

while i didnt have that done on mine, i have had my TCT removed recently and it's a easy straight forward job. worth getting the 3 o-rings from honda though; 2x round ones, and a triangular one.
the orings on mine were hard and starting to crack and thus causing a slight weep of oil

other posts report sandblast as around £10.
orings will be another £10 for all 3.

 

PM me

I'll send you a sandblasted worm gear for the cost of three 2nd class stamps.

You must return your old one however

 

Can anyone advise me on fitting this?

 

Proceed with caution. I will not take any responsibility for any damage incurred to you, or your vehicle. You remain responsible for your own, and your vehicle's safety at all times.

Ensure the engine is cool

Remove the airbox assembly. There are three 10mm bolts and a few clips to undo. Most aftermarket intake kits permit access to the maintenance hole.

Remove the maintenance hole bolt. It has a large allen head on it. Make sure you remove the lower of the two on the front of the engine. The upper one secures camshaft timing gear components ...DO NOT TOUCH THIS ONE! A T50 Torx key is my favoured tool

Remove the two 10mm bolts that secure the TCT onto the engine, not the bolts that remove the cover on TCT.

Wiggle to TCT so a small part of it protrudes from the front on the engine. Using a flathead and hammer, gently remove the TCT.

Place you finger firmly over the end of the TCT to prevent the innards falling out.

Take note of how the innards are assembled and remove them. If they have already fallen out, have search to find the photo of how they are assembled. Make sure they are cleaned.

Fit the sandblasted worm gear in place of the old one.

To retract all the components, push and turn the piston. If you do not have the correct pin to secure the innards, use a strong, but short needle in the two holes at the end.

Place the TCT inside the engine and tighten the 10mm bolts.

Using the maintenance hole, pull the pin (or needle) out a very small amount, using long nose pliers. Re-grip the pin/needle and pull all the way out. You should hear the piston extend. DO NOT DROP THE PIN/NEEDLE INTO THE ENGINE.

Replace the maintenance hole allen bolt.

Double check everything is secure.

Start the engine. A rattle for a few seconds is normal, this is just the piston extending. If the noise does not subside within 15 seconds, stop the engine and check what you have done is correct.

 

since you have the worm gear out of the engine, find a bolt, nut and washer that will fit the thread. makes the fitment & locking pin insertion 10 times easier.

also im not sure it's possible to loose bits down into the engine.... not if it's all assembled anyway (could be wrong, just my opinion)

 

As the new worm gear is much coarser, there is no need to worry about this

It is possible to lose the pin when removing it. If it ends up in the timing chain case, then you have a BIG problem on your hands
