Hey guys I was out doing some fine tuning of my EBC and when I came to a stop I heard a "Baseball card in spoke" type of noise. As soon as I gave it some gas it went away but it is pretty loud, I mean I can notice it from in my car. I just filled up the oil, so there is plenty of OIL, I was running the car fairly hard, but not to REDLINE and I red a while back how SoulCoughing had Scuffed his bores. I know he has an AP1 so maybe that is the problem, but I dunno.

I was running mid 11's at the very leanest so I dont think I "blew something" doing WOT runs

Anyway what do you guys think?

I saw a DIY for TCT the only thing that scares me is if all the little pieces come out when I pull off the old TCT

Help?


ALSO Witht he Greddy PROFEC Elec Boost controller it says I am at 11.8 PSI when I am steady WOT, but when I release the gas it shows my last BOOST as like 12.3-12.5 it usually always reads .5PSI higher? DO I believe that or the real-time gauage?

Also what do you guys think is more accurate the Greddy Digital read out or the Autometer Mechanical gauge?

 

this is exactly what it sounds like, it has been 3300 miles since last oil change

Does it sound like the motor, the turbo, air, or some kind of silinoid?

this is exactly how it sounds so I guess its the TCT, I will change the OIL 1st thing tomorow morning and I guess order a new one, install looks easy

 

if thats the noise, then yes, its a TCT. The scuffed bore noise repeats at a much slower speed at idle.

 

Try having the worm gear sand blasted before you buy a new one. Just bring it to any machine shop and have them hit it. They'll do it cheap/free.

 

What does TCT stand for? Pardon the ignorent question.

 

Timing Chain Tensioner. Some model s2000's actually had a TSB issued about them wearing out (I think). I think they were the earlier years, though.

Got to replace mine. When you do it, it helps to have the valve cover open, so you can "grab" the end of the tensioner with an open wrench, to keep it from spinning/re-engaging when working the bolt/lock nut. If it spins or shakes too much while you are counter-rotating the nut to lock it, the spring will re-engage, and you will have to start again.

Yes that sounds like a TCT.

I have a used TCT that is in perfect working order I can sell you if you need one. I replaced mine with a modified design because my head is milled. $60.
