@BobbyBreeze any idea what sort of vacuum I should be getting at idle with a pretty mild cam? The fresh engine is sitting at about 65 kPa absolute at idle (10 " mercury pulled), with stock cam I was at about 35 kPa (19 " mercury pulled)

 

I'd say around 16-17" Hg with a mild cam. Generally stock nanna engines are ~20" Hg, Hot street engines 13-14" and full race 10". Any chance you have an intake leak anywhere? 

[ajg193 8,245]

No intake leak I am aware of but I I'll take a detailed look

Idle has settled at 13.5" after tuning.

Saying that, I am running excess air through at idle and using the ECU to control the timing to pull idle speed down to 1000 rpm, just stops the speed undershooting 1000 when coming off throttle with headlights on. Timing needs to constantly jump around between 5 and 18 degrees to give it a smooth idle, with a bit of offset depending on if electrical loads are active

anyone here got a Geiger counter?

[Transom 5,008]

Na but keen to get one as I sometimes work right next to the largest uranium source discovered in nz so far - to aliex to look for one now 

what are the utes you sometimes see with the radiation hazchem Symbol on the dg placard ? Rad source and counter for pipe testing ? 
see them a bit / one got stolen last year and they had a wee panic 

[igor 12,174]

Nuclear densometer maybe?

[Transom 5,008]

Maybe is that a geotechy type device ? 

[tortron 55,697]

yeah for measuring how compact the roads are. was gona do it for a summer jerb once

 

 

@RUNAMUCK, i like old stuff. The 1950s and earlier were a H&S wasteland.

 

I know its radioactive just cos of its age, i wanna know if i want to store it in the shed or in my undie drawer

[Transom 5,008]

So why are you after a Geiger counter ? Got some old watch dials to lick ? Or have you possibly uncovered a terrorist plot ? 

[tortron 55,697]

yeah i have an old watch, ww1 trench watch and about that time they absolutely gobbed the radium on, so its likely pretty hot.

[tortron 55,697]

Quick mafs of 6 roentgens per year wearing it every day if it's like the one I saw on YouTube.

Not good, not bad

Any tips on how to remove this wheel nut lock? Outer shell just spins. No tool in the car that I can find.

Looks like it needs a key? So smash the shit out of it with a screwdriver? Or there are some that need magnets.

Oh yeah, that's a key slot. I thought it was a name or something. I don't have the key so will resort to brute force/grinder

Winner, thanks Rogee! Modern vehicles are so flash.

Now, any tips on removing aluminium valve caps that have been soaked in sea water?
I think I'll have to get new valves fitted to all 4 wheels.

Sidecutters will remove them
