She's running


Rough as a dog though. Don't understand…the time before when she was leaking oil the idle seemed smooth and all sorted. I've done the ignition timing, but oddly she seemed happier with the vacuum to the dizzy off and closed up than when I reconnected it.
But she's also making a very funny noise, almost like a cat meow. You should be able to hear it in this video…it's like something is rubbing. Took the timing belt cover off to have a look as it seems to be coming from there, but could not see anything out of the ordinary.
Is it just because I've never really listened out for oddities before and I'm worrying over nothing? One of the times it stalled today I tried to restart and it seemed the engine would turn and then jam!!! 8O Basically it would crank round slightly and then stop. Tried to video it and then as soon as I did…she started first time!lol.
Any thoughts? Timing should be right so I pray I'm not clashing valves or whatever it is that happens

The new rocker cover obviously is a lot clearer for the breather. So would this effect idle and everything with more air going through? Just a thought

btw, if its a 1.8 gti you're supposed to set the ign timing to 6deg BTDC with the vac line to dizzy disconnected and plugged. then reset idle/co to suit

Today's findings…it seems (unless I'm taking a reading wrong….but I cannot see how) that there's no power to the TTS. Stripped the cable back to where I found a dodgy area…and still no power to that bit either…so there must be a break along the line somewhere yes? Which if this is the case means removing all of that plastic housing around the cables yeah? If so…doh!!!
BUT
Am I right in thinking the TTS only controls the 5th injector? So what I did was remove the 5th injector (my thinking was if that's not getting shut off by the TTS then the engine will be getting too much fuel and therefore drop idle as she warms up)…but she still drops idle whilst warming up.
Are all my thoughts here right? If so, I'm still clueless as to why it's dropping idle speed when warming up.

Look again at the circuit diagram for the 5th injector and thermo time switch, you might have diagnosed it wrong.
Dropping idle speed through warm up is normal. What's it at the start (after cold start) and once warm?

if the idle is at 200 when trying to set the timing that wont help, you want it around 900 rpm. as paul says let it get to 80 degrees then set idle to 900 and recheck the timing. its definitly got the right flywheel on it?
you should have 2 marks. a small punch mark which is the TDC mark used when settign up the cam/crank timing on the belt. then there is a big diamond quite close to it which is your BTDC mark for the ign timing. a carby flywheel has the mark in a different place, and iirc 1.6 gti doesnt have a BTDC mark at all?
this is what it should look like, big red diamond is BTDC, small punch mark next to it is TDC. this is a 6deg BTDC flywheel as well so it will give you an idea of where it should be:

There's also no power to the WUR. So I guess that would be why it drops so much then? Don't know why none of these are getting any power, seems very odd!!!
