Tax disc holder now taped to the screen.
Rubber trim no longer makes contact with the body at the upper corners.
Got to clean the bloody masking tape glue off it!

 

They seem to have a knack of knowing just how much of a bodge they can do without it being worth you complaining.

Still, you faired better than Mrs. KW with her MX 5 at RAC. Every cap covering scuttle retaining screws either missing and replaced with a blob of sikaflex or broken. Scuttle cracked around every retaining screw due to over-tightening. Wiper nut cover missing.

If I ever need one replacing again the car will be presented with everything stripped off so they don't get a chance to bu66er it up.

I think their scuttle removal technique is something along the lines of:

1) Tie scuttle to back wall of garage
2) Reverse

I have on the Westfield. I used to put it down to the fact that it gets kept in a dry garage most of the time, and perhaps this causes the rubber to perish. At one point I was replacing the ball joint rubbers annually.

The AC system auto calibrates based upon lambda readings, there is an initial set up required which i would imagine all systems need to have, but in the past when i have looked at the mapping sometime later i have found that the curve is different to the one we originally created.

Remember that the petrol ECU will have long term fuel trim values, probably individually for different parts of the fuel map, so if you don't get the calibration spot-on the fuel trim values will adjust to compensate. Then, if you run it on petrol for a while, they'll adjust back, so you can end up chasing your tail.

I could be wrong here but i was led to believe that LPg requires the injectors to be open for a longer duration due to the differences in the fuel, would this not be an issue if it is using the petrol injectors as its source?

Injector duration is purely down to how rapidly the fuel is delivered through the injector, which, for LPG, depends on the vapour pressure and temperature and the nozzle diameter. If the fuel delivery matches the petrol injectors then the duration will be the same, however, the LPG system will apply corrrections based on the above parameters so it may not stay the same under all conditions of speed and load.

i wouldn't mind betting that when you get down to it the kits are not a million miles apart from themselves
and anything that saves money cant be a bad thing  

Just looked on the ECU manufacturer's site and, give or take a few details it does look very similar to the AC unit.

Looks interesting, and sounds like a good price. If it's anything like the AC kit it will need a bit of a tweak on the road. autocalibration on that kit really only got the idling right.

Keep us updated on how you get on with that.

Ask them what kit they're fitting too. There's a fair difference in price between the top of the range prinz stuff and the cheaper kits. Not sure how they compare performance wise but the couple of AC kits we've fitted must have clocked up a few miles by now.

I keep meaning to work out what the options are for doughnut tanks in my saloon and get the bulk buy moving again.

I would have thought with a couple of guys working on it who have done the job many times it should be easy in a couple or 3 days.

Also, make sure they're not going to be drilling manifolds in-situ or any rubbish like that. (thankfully a bit of a challenge on a V6 anyway unless they go in through the plenum top.

"Other halves" can be surprising sometimes. I went to the scrap yard once looking for parts to fuel inject the Westfield. Emma decided to come too and I was dreading it turning into a shoe shopping expedition.

However, I explained that I needed some injectors with a high flow rate, so she should look for the most powerful 4 cylinder car, and if it's got a thing that looks like two old fashioned hair dryers bolted to the side of it so much the better. A Turbo? she said.  

Anyway, she ran around the yard like a squirrel and found a superb set of injectors that are doing me proud to this day.

Did you manage to sneak those heads into the dishwasher with a bit of Jizer, though, James?

It'd be worth checking the timing with a strobe once it's up and running, especially as you're relying on markings. Also check for play as Mark said. If there's a bit of jitter in the timing it might be why the idle has deteriorated.

Just re-read your post and ifyou haven't removed the dizzy, just turn it back to where it was and ignore my last post entirely   since the mesh of the drive gear won't have been disturbed.

Ahh, ok. Didn't realise you were doing major surgery. In that case, you also need to make sure that the distributor shaft meshes properly with the drive gear when reassembling, so that it is in the correct location relative to the engine, otherwise the marking you made will not correspond to the correct timing.

Does this engine have points in the distributor or an electronic setup?

.. and if it's been apart it might be worth finding something that will engage with the oil pump drive on the lower end of the distributor shaft and give it a whizz on an electric drill until you get oil pressure before refitting the dizzy just in case the pump priming issue that Mark mentioned rears its' ugly head.

If you're only replacing the cap surely the body of the distributor (the position of which sets the timing) dosn't have to be disturbed? If it's loose and can be turned by hand it needs to be set correctly and secured in that position.

The cap is usually keyed so it will only go on in one position, and then you just have to make sure you got all the leads on in the same positions as they were on the old cap.

It could be either since the firing and intake / exhaust happen on alternate turns of the crank. I think I'm right in saying that with the cam markings also lined up it's the firing stroke for cylinder 1. Remember the other cylinders will all be at different positions in their stroke. The crank marking is only TDC for cylinder 1 (and 4).

A3 is a newer specification than A2, and superior.

It's a thinner oil, of course, but a RV8 will be fine on 40 visc.

VX Semi will be fine in a Rover V8, as will the coolant. Just give it a good flush beforehand to get rid of any old coolant.
