    Timing Belt slippage - What to do?!

    OK so some of you may know from the Knockhill thread that my timing belt slipped when the belts in front of it went.

    I checked yesterday and it slipped one tooth (or one turn less one tooth!) so I re timed it and cranked it over on the off chance I was lucky! No such luck... 8 out the 10 inlet valves are bent. No biggy really I guess, like I said at the time, I'd rather that that smash it into the tyre wall!

    So the question is, what do I do? Bear in mind labour costs nothing when suggesting!

    I need to replace a thrust bearing as it doing my t1ts in! So should I get an uprated clutch? (I am intending putting in a 3071/6 or CT355 soonish) If so, what one for an ABY?

    Should I take the block out and do the rods? I am thinking yes as its half out anyway...

    Should I put in the 7a cams, or try get hold of ADU ones, or are ABY ones fine for the turbos I am looking at?

    Where is the best place to get the parts I need? i.e. ARP head bolts, gasket, rods...?

    If only I had bought a k26 Evo EM rather than the T3 one, I could have fitted it too! Now I need to think if I should sell the EVO IC that has never been fitted, and get a reverse one from Wagner too...

    Ahh, so many decisions!

    Thanks for any advice guys

    If you bend so many valves it sounds like the belt slipped much more then 1 tooth. I would rebuild that cyl head and also check the pistons for damage. Also I would go for a single mass flywheel if you uprate to those turbos. The rest of your questions are answered in other topics, so please search for them

    Good luck

      Repo was selling a used ABY Sachs (I think) that'll save a few £.

      As for the rest, get the head built properly and flowed, might even be worth getting larger inlet valves if you're going to buy new ones anyway.

      As for the rest of the kit, it all depends on budget... as Bram says, it's mostly been covered in the project threads so get reading

      7A cams are a matter of taste really, all 3 sets can be used but give different characteristics, I'd speak to whoever you get to tune the car to see what they suggest for your turbo.

      I'm sure the k26 EM will sell in 0.01s flat.

          Cheers guys...

          EVO IC is unused, so it depends on whether I can afford a reverse IM kit along with the rest of the stuff needed.

          The head I will just replace the valves that are bent as I don't think headwork is really needed for 450 - 500 HP... Pistons are fine, and the bores look like new

          If I sell the EVO IC Nesshead, you have first dibs

          I dunno about a single mass flywheel, whats the point? does the dual mass not take the torque?

          OH.... Does someone have a photo of the teeth on the Cams where the chain goes? they look awfully rounded on my car!

            My fecking Internet is down and no sign of a fix anytime soon! iPhones are fantastic, if you get signal at home, let alone 3G!

            Anyway, seeing as i can't surf i'm after help!

            1. Arp head bolts, aby, 204-4207? Is that right? And is £137 ok?

            2. Anyone know anything of K1 rods? I was gonna go scat but are these good?

            3. I can only get 5 inlet valves from Audi, suggestions?

            4. A link to shells?

            5. Head gasket? Genuine Audi, or other?

            6. Really would like timing chain sprocket photos!

            Thanks

              Mike, met at knockhill (blue RS2)

              Cam sprockets, teeth are surprisingly rounded, noted this when I rebuilt my engine so don't think you have an issue there but deffo new chain

              Head gasket, use compression dropping multi layer steel gasket which is basically 2 head gaskets split taking the top shim and thick shim from 1 and thick shim and bottom shim from the other then pop rivit them back together, was shocked when I got mine from 034 and that was what they had done, they were standard reinz gaskets, by memory drops CR to about 8.6, 8.7

              will go well with the CT355 you are going to use, looks like I may use that turbo as well in the near future in place of the 3071

                Thanks Paul, I will have a look for a gasket, should I hold off doing it til I do the turbo then? Not sure dad will be too happy with a steel gasket, he just told me he hates them, they always leak!

                  I am also unsure on what clutch to get, what do people recommend?

                  I don't do a lot of traffic driving, but on the other hand it is a daily driver....

                  Damn car!

                    I have had my Southbend stage 4 in for a few weeks now and although a little stiffer than stock, I got used to it in days (although the wife complained at first) and now I think it feels normal.

                    The feel is perfect for the road and bite is amazing - full bore launches with no slip

                    Speak to Marc at EFI Express for some good info and good prices.

                      Standard audi gasket is an all steel affair anyway, Sachs race clutch cover (707) then a choice of 6 puk or full face clutch, Don't see many threads where people complain about their clutches although not the cheapest but best never is

                        I thought it was supposed to be a steel one but pretty sure mine is paper.

                        Thanks for the help so far.

                        Can anyone confirm that arp number, or k1 rods? And what shells! Ta

                            If I remember right early cars had paper head gaskets and later steel, with some noted anomalies.

                            Good luck getting it up and running again.

                              Paper head gasket was phased out with 3B... steel item is much heavier duty.
