These are one of Chris' pet "we need to work out a solution" parts, as they are *all* knackered to varying degrees, hence the characteristic 340 prop rattle in idle. Some are less knackered than others, I spent a fair chunk of time trying to find a more betterer one. Can you feel play in that place...

Pump is same as in 200, 700,900. Newer small type with separate reservoir.

ok.

Ok, thanks to both. I hoped it is more toward 200.000km like on red block

Wonder what is by experience average interval for adjusting valve clearance on B14 engine. Volvo book says 20.000km which to me seems rather small. Is any difference in reality if solely LPG is fuel, this engine looks pretty robust with valve seats. Is anything specific to make attention when adjust...

Different approach is to use pragrammable ignition used for converting to CNG adn LPG. I have experience with TAP 01, AC STag, from Poland and it works as designed. You connect it between orginal crank sensor and Renix box and through windows software change ignition curve as you like, advace or ret...

Common thing for all of that is so called X relay, which supply switched 12V (electrical contact nr 15 in schematic). It is situated under the dash, somewhere in the middle, left of key- for LHD model. It is metal square with 4 wires on. Never saw RHD model so maybe is different location. On schemat...

With worn gaskets engine can not run ok, so you must fix that first before any adjusments made either on gasoline or lpg. For LPG you need mixer and possiblne air recstriction before air filter to achieve around edit> 3kPa pressure drop for reducer membrane to work correctly and to have LPG responsi...

To me looks like EGR valve typical problem when stuck from deposits.

If you don't want to wait I can tell you that when it rains, the filter will get completely soaked and won't let any air through anymore. From date of post there was a lot of snow, ice and of course rain till today to test solution. No any problem you write about with the filter BCF197, air is comi...

Of course, but TIC diesel- turbo intercooled 6cyl made by VW.

I admit that have very short experience with B14 engine, thanks for suggestion. With big Volvos it is customary to expect to change rotor and cap once in engine lifetime, usually original lasts 250-300k.(740 and 940 red block engines) Currently in my 340 it is cap from japanese "555" of unknown hist...

Duclier ones will last about 15,000miles. Anything else, between 5 and 10,000. They really do make a difference. It's worth if you don't already joining the realm of the geeky side and keeping a log of fuel consumption (even in your head, it's noteable) MPG will really drop off when the dizzy cap s...

EGR is drived from igniton ECU, lambda sond have nothing with it. It is used only on 1995-1996 m/y B230FK engine and is made by Pierburg. There is no single Watt gain from removing it but there is loss in perfomance when EGR is not working properly as ignition ECU puts engine in sleep mode (mode for...

In my 340 problem was gap between two halfs of heating box (big black with fan inside) as water drips directly on that seam from air louvres above it.. And sponge like big round spacer between heater box and bulkheadhas turned to dust. Found water droplets from air ducts. But water drip inside only ...
