Fuel Consumption!!

what sort of merc is this, that valve doesnt really look healthy. Im going to guess this part comes from a merc made between 1997 and 2003

A stationary one?

Anyway, it's only flat at the bottom....

id be gobsmacked if its come out of a 300d, but unsuprised if its come from a late 90s early noughties car.

Sorry, I should have said.

It's from my VW car transporter, the one I was talking about on page 1 & 2. It has a Merc 230 engine and a Tickford Gas conversion. But running on lpg, it keeps burning the valves out! We've had the head off twice now in the last 6 months. It's almost back together again now, but I wont be running it on lpg anymore. Just unleaded from now on. I dont care how thirsty it is, I'm not taking the head off again.

its unusual to see a petrol van these days most are now dervs, with an lpg you need to change the oil more frequently.

It's a 2000 X reg in the year, About that time a lot of manufacterer's were making a big thing about lpg and I believe this one was fitted new. One of the problems is getting someone to service the system. None of the local gareges want to touch it as there not familier with a system this old.

Where I worked back in those days as a live working cable jointer for Bethell E.D.S Utilities, some of our vans issued that year were lpg converts. I was one of the lucky one's and got a diesel model. The lads that run the lpg's didnt like 'em.

I've had lpg's before, Had a 1994 Dodge Ram with lpg on a 318 cu. in (5.2 litre) V8 and that was absolutley brilliant! Some engine love it, some don't.

ah yes the ram, my uncles and my dad have their lpg fitted at some place in craigavon

there was my dads miniscule primera sitting there, and then this beast of a ram sitting behind it in the workshop. I dont even think a ram does good economy on lpg just about what a rangie would do. But they are so much bigger than everything else on the road.
