Which valve saver kit

Hi all, Just wondering, in the process of finishing the rebuild on my Discovery 3 4.4 v8 which was misfiring after running on gas for about 80k. I haven't opted for hardened seats due to cost, so thinking of fitting a valve saver kit to hopefully get a bit longer before the valves recess again. Not ...

Re: Fault symptoms

Just a quick update for those who might be wondering. I have done only about 300miles since the cat was fitted, but early indications show me getting around 45MPG on petrol which is what I was expecting. Still not had an opportunity to fix the LPG system so only ran on petrol so far. Many thanks for...

Re: Fault symptoms

Had the cat done yet? You know there are multiple ltft's not just one. As you move from a different rpm / load combination on sections of the petrol map, sections of the map can have separate ltft's...

Re: Fault symptoms

Thanks Simon for the comprehensive reply On the other thread (talking to the OP now) you also said you have low compression on cylinder 4 (more than 20% lower than the other 3 cylinders)... I think I have updated the other thread (second page so may have been missed) that I completed a compression t...

Re: Fault symptoms

2.2 bar is absolutely nominal for Prins system, they are not like others. But as that's a lower pressure than petrol injection, fuelling will be affected more by factors like increased manifold pressure - due to a blocked cat for instance. I wouldn't bother messing with the gas until the other issu...

Re: Fault symptoms

Okay thanks for assistance with the pressure. It is running Keihin orange injectors, not sure about nozzles. The pre cat lambda seems to be working fine. Voltage values continually change from 0.84v to 0.12v completing a full cycle (from 0.8 to 0.8) in about 1 or 2 seconds. The post cat lambda is st...

Re: Fault symptoms

Thanks for your reply. I thought the vaporiser pressure seemed a little high, any suggestion what it should be, about 1.4 perhaps? Fuel trims are +30%. When I say +30% I am taking an average. They would sit around +6% on petrol, when you switch over to gas the fly up to +50% but waiver all over the ...

Fault symptoms

Hi all just wondering if there were some common symptoms for the following situations: Injectors blocked by heavy ends? Failing vaporiser? Cracked injector pipes? False RPM signal? Vaporiser pressure too high? Bit of background, I have been suffering poor MPG on my Clio 1.2 16v at around 30mpg - see...

Re: 1.2 16v Poor Economy 30mpg on petrol or LPG

Another update for you all, gone a bit quiet as I have been installing a Prins kit on my other car a Sportage, running excellent now! I took the leap and bought a compression testing kit myself as something was niggling at me about the garages results. Anyway Findings below: Cylinder Dry Wet 1 146 1...

Re: Prins Service on DIY Fitted System

Well, just a quick update for you, got the new install calibrated and the software updated by Blair from Autogas 1 Ltd, excellent chap. Worked a treat, said it was very good actually, few tweaks but running well. Just got to get it certified and on the register now.

Cheers for your help.

Prins Service on DIY Fitted System

Hi all, This weekend I have just finished installing a Prins system onto my Kia Sportage 2.7 v6. It was a second hand system bought off eBay, I have tried it and it works fine. It switches over fine, runs perfect and pulls just like petrol. I do have some "Prins" software bought off eBay, connected ...

Re: 1.2 16v Poor Economy 30mpg on petrol or LPG

First thing to do is check valve clearances (tappets) and adjust if needed before you strip the head off Just did that. The rocker cover was leaking oil, so changed the gasket, took the opportunity to check the clearances at the same time. The exhaust valves were tight, but the inlet ones were fine...

Re: 1.2 16v Poor Economy 30mpg on petrol or LPG

Well not the news I was after. Compression test showed 128 to 130psi on cylinders 1 to 3, but cylinder 4 struggled to get to 100psi. I believe that would explain the poor economy, but it does seem strange to me as the car has been doing 30MPG since I got it in May last year, has not got any worse, a...

Re: 1.2 16v Poor Economy 30mpg on petrol or LPG

Thought I would give you an update. I have the car booked in tomorrow for a compression test, so will let all know the outcome of that. Could anyone offer some advice as to what values I should be expecting? I have also bought a known good genuine cat and two lambda sensors from Renparts for £68 del...

Re: 1.2 16v Poor Economy 30mpg on petrol or LPG

Thanks for that little tip, I will give that a go tomorrow. I have got a quote from Renparts (through the Renault forum) for a tested secondhand cat, with two lambda sensors for £68 delivered and a three month warranty. Also can get some money back for the cat apparently. Tempted with that, as the c...

Re: 1.2 16v Poor Economy 30mpg on petrol or LPG

I would also suggest as first step both a wet and dry compression test. That is what the garage suggested, but they do not have the adapter to do the test (because of the long narrow holes leading to the spark plugs). Is there anyway of checking the flow on the CAT without replacement? Old fashione...

Re: 1.2 16v Poor Economy 30mpg on petrol or LPG

Thanks for the tip, £75 odd isn't too bad. Have heard aftermarket CATs can throw up the EML, anyone got any experience of this?
