I drove home after class had a coffee, did a few stretches, had another coffee and ibwas ready for the challenge..... 20mins later its done. Cheers guys, the hardest bit was getting the new balladesports tct in all the way, opted to screw it in gently with the bolts, just nip tight!! Then wing nut and screw out, and centre screw thing in just until it stops, then back plate on just nip tight.... ran it no rattle at all.... stopped & started again no rattle, usual ever so slight tappy niise that is normal its nice and quiet now.... so we will see if it stays that way moving forwards nicely.
My blood ran cold when I read this, what you have done mate is put pre-load on the timing chain, you are highly likely to have some engine dramas in the not too distant future. This isn't me being a smart arse angel of death or anything, but please read this thread https://www.s2ki.com/s2000/topic/109...t/page__st__75
Just to do a snap shot of it here is a quote from Billman (who in the best way possible is a smart arse
)[quote = name 'Billman250']
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. 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.
You need proper advice on this but AFAIK you will need to back turn the engine slightly to give the "loose" side of the chain a bit more slack, good luck.[/quote]
So it sounds like what he did wrong was draw the TCT in with the bolts, when it should have been possible to seat it and hold it with a single finger, then tighten the bolts? Then it's a case of removing the wingnut/bolt and replacing with the flat-head bolt?

Yeah, Nathan told me it'd be another 2-3 weeks on the 9th, but it showed up yesterday, having been dispatched on the 11th.
Dear Lord, what a difference. No more ticky/tappy engine on warm tickover! Took my sweet time, made sure I did everything right, even bought my first torque wrench for the occasion
Just mid-way through a test drive and all is well.
Thanks to all for the advice, yet again!
