V6 406

[Doggy]

The armrests in the saloon are something I've got very used to, driving a car without them now feels a bit weird. But there still seems to be a few on ebay.

I don't know weather to go for the 2.2 HDi and get it remapped, or the 3.0 v6.
The V6 will obviously sound much better and be that bit livelier and has the option to be converted to LPG
but the 2.2 has the fuel economy, is there any other advantage, would the v6 be more reliable in that it does not have a turbo and all the plumbing.

A few points to ponder:

I'm now getting 50 mpg.
Some remapped 2.2 HDi's are now producing more bhp than v6's.
So far, no-one's done a 6-speed upgrade on a v6.

(not that I'm biased)

But do not forget that some V6's produce a __LOT___ more bhps than three 2.2's

I got a quote from the lpg place they would charge £1200 for a brand new sequential lpg kit, apparently its the latest type with registration on uklpg and an unlimited mileage 3 year warranty on the kit, and this is for the 6 cylnder i thought they were quoting for a 4 cyl.

You could end up with a really nice car for not that much outlay at that rate, V6 406s are cheap as nobody can afford to run them.

This is a particularly nice one: http://www.autotrader.co.uk/classified/ ... 013844040/

Make sure they fit a flashlube or similar kit! Otherwise you'll be replacing the heads in several months!

I see that car every day.

On paper, they get worse fuel mileage than the 2.2 petrol, but in practice they're dead even. And it makes an additional 50hp and 70nm. It's a very reliable engine as well, and shouldn't burn any oil.

So any additional cost over a 2.2 petrol would be insurance and very specific maintenance such as the timing belt.

A friend of mine has nearly 250.000km on his V6, no issues at all. The flashlube stuff sounds a lot like snake oil or an unnecessary fix for a problem that doesn't exist.

Edit: To be fair, he doesn't run LPG in it, which may be a factor.

The flashlube is only for lpg, so your comment about your mate's V6, while interesting, is completely an elephant

I keep hearing wonderful things about modern lpg conversions but I'm still put off by the amount of times I go to my mate's workshop and see quite new cars with lpg-related cylinder head problems. I saw one a few weeks back, only a few years old Opel Ashtray with not only a mangled cylinder head but also a couple of pistons that made an awful clonking noise when you pushed them fore and aft, and it had some kind of upper cylinder lubrification system akin to flashlube. Stuff that

The LPG'ers run too hot and don't benefit from having petrol whizzed over the valve seats (in my opinion) and my mechanic says they're sh*t.

[KozmoNaut]

Is LPG really worth it any more? How much cheaper is LPG per mile travelled compared to petrol?

The conversion itself costs money, and if it increases the risk of cylinder head damage, I have a hard time seeing the benefit.

[Bailes1992]

LPG gets a bad reputation due to piss poor installs by so called 'professionals'.

LPG burns slightly hotter but providing you have a half decent cooling system it shouldn't cause any issues at all!

Problem is with LPG it is much 'drier' and doesn't lubricate as we'll. This is why valve seals wear away!
Now lots of cars can cope with LPG with no aftermarket additive kit but many cars can't! Personally I would fit flashlube on any car that was converted to LPG.
Flashlube and other similar systems were originally designed for engines designed to run on 4star fuel in order to stop the valve seat receding when running unleaded petrol. They also work very well on LPG conversions!

People who have destroyed head gaskets and rings are usually down to poorly fitted or maintained systems running lean or rich!

You only have to go nose over on the LPG forums to see cars that have done hundreds of thousands of miles on LPG perfectly reliably! There's some superb examples of installs too!

LPG is around 55-63p per litre where as petrol in the UK 125-135p so there is significant savings too!
Also a well set up system will have no decrease in performance and will run extremely clean! Oil stays unbelievably clean on a car running LPG!
Get it fitted by someone with a good reputation and have the system service every 10k including getting all the fuel trims checked then it will be as reliable as anything else on the road!

Is anyone else scared to search the internet for "flashlube" or is it just me?

[steve_earwig]

Disappointingly, even with safe search turned off, Google brings up nothing to be scared of...

[FarmerPug]

I think the kit comes with some sort of lubrication setup. My dads primera fan fine on LPG, it was bought by a taxi man and its still running.
My uncles previa has been running fine on LPG for well over 6 years now.
Both cars had their conversions done at the same place in craigavon.

[steve_earwig]

Sounds like they know what they're doing with it then.

Tbh it wouldn't surprise me if there was nothing wrong with the lpg installs here and the problem is Croatian lpg is as poor quality as all the rest of the fuels.
