Carbon build up causes hot spots which can promote detonation. Oil vapor in the combustion chamber increases the propensity to detonate because it has a lower octane rating than gasoline.

I don't see obvious signs of detonation.

 

I got the majority of the carbon off with degreaser, gasoline, or a copper chore-boy pad.

Now I'm wondering where my marks on the fuel lines went. The one nearest the front bumper is the return, and the one nearest the firewall is feed, right?

On my bubble burping hill, need the hood then I'm done, or so I think...

 

Sorry for dumb question, I'm curious. On the 1.6, do you have to retorque the head gasket at any point when changing it? Or is it just torque to spec and you're done? I've drove a 1.6 but never owned one. People hate on the 1.6, it rev'd and ran pretty damn good the one I drove, I liked it.

 

Nope, just torque and you're done.

 

I torqued it once, then rechecked it the next day after I did the cam caps for the hell of it, they didn't move at all.

 

Started on the PCV setup...





Remove all the throttle body things. I lost the spring clip for the TPS sensor, so it goes out and my idle gets stuck. I have no idea where to find another.

 

Nice touch with the o-ring retainer spikes in the groove. So oem, much japan.

 

Hah, it's a gnat's fart under 1/8". Since I had to use a tiny 1/16 I figured I'd get fancy!

Since I have more of this 1" UHMW I'm gonna make some door jamb things, because reasons.

 

So I had to change my plans a bit, but the blocks fit pretty damn good. Ended up being slightly larger than a 1/2" radius to fit snug, belt sanded a chamfer on the leading edges so they'd fit flat. My passengers side door closes a lot easier now which is super cool, haven't driven enough to notice a difference just yet.

They grind on the screws that hold the pocket to the door, so they make their own clearance at least. Couldn't make them any taller if I wanted to

Ah nice, thanks man. I just need the little metal "C" clip that holds the connector in place, nice and small heh.

 

Don't know what piece that is. Try and find a picture. I'll get it pulled tonight.

 

The little metal clip, it's C shaped. Mine is gone, looks a little different than this one though. Unless I'm mistaken you've gotta pull that clip off before you can unplug the TPS.

 

Ohh that thingy. I bet you could make one with some wire or something. I'll see if I still have mine.

 

Nvm I have a BMW tps different connector.

 

I'll probably just cut the bitch off and wire in a new weatherpack connector or something. If I don't drive hard it doesn't unplug itself lol

 

Zip ties.

 

fwiw- bore-friendly PVC pipe works well
