Hello Billman and other sirs, I recently started hearing this ticking noise coming from my engine. Do you guys think this is a TCT problem?

That is TCT noise 100%.

 

ok, you've been pmed thanks

 

Had a car in with a built/milled head, and IP TCT. Customer states the entire build and TCT are one month old.

With the milled head, there is no preload on the chain when installing the TCT so that's good.

The pin however is not hardened, and is already showing a wear ring in the middle. Can have the customer chime in if needed.

 

stumbled across this.

10,000 miles on a ballade.




whats the production date for the change over?

 

This is just unreal... I'm glad I brought this thread up because CLEARLY there are many others out there. Nothing like having additional metal powder in your oil increasing wear to other components of your engine due to a non-hardened pin.

 

I have asked this also, it is the cornerstone question of this thread. If the thread dies, time will answer it.

What I mentioned earlier about chain preload is paramount. If anyone has installed ANY TCT (including mine), and had to draw the TCT in with the bolts, then your camwheel bushing is going to be the first casualty. It is very small, and when it fails the entire engine will suffer an oil pressure loss. The bushing will starve, overheat, then fuse itself to the camwheel inner spindle. The spindle will then rip loose from its mounting, and spin on the bolt until it overheats and fuses to the bolt, snapping it off. It will shred the head surface where the camwheel spindle sits, melt the cam caps, and destroy the bottom end as well. We have already learned this from loose camwheel bolts that were reported and that I have seen personally.

If you can HOLD the TCT against the cylinder head with the pressure of one finger, you will be fine I assure you. You can then install the bolts and tighten them, provided you can hold flush with one finger while doing so.

If you cannot hold the TCT flush to the head with one finger, and you pulled the TCT flush to the head with the bolts, the chances for severe damage are going to rise greatly. If you are in this class, I strongly recommend you pull the TCT, retract it, and re-check the preload (attempt to hold the TCT flush to the block with one index finger) this goes for all TCTs in existence.

 

When installing a tct and it does NOT fit flush but does so after turning the crank bolt a tiny bit(as said to do in the Ballade directions due to tension on the chain) is it ok still??

 

Yes that is perfectly fine.

 

There are two ways to retract the tct. With the pin provided on oem(I think) and billman tct's. there's also, as described in the tct stickie, a way to use a small bolt to retract the tct. The bolt method is ok, right?
