lpg help - getting 6mm pipe on the injectors
« on: 06 May 2011, 18:30:34 »

I'm having a mare getting the 6mm piping onto the investors. What's best, a bit of heat on the tops of them?

By the way I take it that the small spring clips go on over the injection union to hold the pipe on...

Yep, although they don't seem to do a lot. Both ends of the injector pipes and the vacuum / vapour pressure pipes.

Aye? the rubber pipe goes on easy usually, it's the Polly pipe that's a pig, ESP the new stuff. Is it the correct piping? ( one wonders )  :-/

Man up! Those little pipes are reasonably easy to get on!

TBH... I usually use a little dribble in the end if it's difficult  :y

Whatever it is... I didn't do it

Well warming the pipe made it easier but still not straightforward on the nozzles.  The injectors were easy as there is more purchase.  I wonder if it would have been easier to fit the nozzles on the pipes first and then fit them to the inlet manifold?

Oh and the mamouth session working till 0030 last night and then again from 5am this morning. I got the car back on the road at 0800 having:

- plumbed in the vapouriser coolant pipe from the back of the coolant bridge around the front
- replaced the HBV
- replaced thermostat (and coolant bridge pipe  >:()
- replaced most of the coolant piping at the back
- fitted the inlet manifold that KW kindly tapped for me  :y
- replaced the leaking camshaft seal.

When I first started her up it ran fine at idle, and then I blipped the throttle and it was running of 4/5 cyl  :o  I was dredding that the cambelt had slipped but I definitely remember torquing it up correctly and making sure it was still set perfectly.  Then I realised that some rain water must have gotten in to the inlet after the thunderstorm hit during the rebuild.  I hurridly had placed the scuttle in place but obviously not well enough  :-[

After a few minutes with a rough idle a few studdering blips of the throttle cleared the last of the moisture and she was running sweet  8-)

End result:

- no more oil leak
- no more coolant seepage (not really a leak but was losing a litre a month plus the sweet smell in the cabin)
- a more normal running temperature
- increased mpg
- smoother
- more power

The last 3 were a pleasant suprise but definitely noticable.  But the whole session last night and this morning was not a pleasant one after playing a whole day of rugby league 9's tournament when you're mid 30's.

Now to fit the rest of the kit  :y
