Hello all
I got my land rover back from the garage this morning and the news was on the grim side. It's a 109 stage one V8, petrol/lpg. It's been losing power and generally struggling for some time now. So, new plugs and leads, which has helped a bit, and a good clean of the carbs (which are fine). Distributor is also fine. The guys at the garage took it round to another garage and put it on 'the machine' (?), which told them that the compression was very low. Also that the spark was very weak on half the cylinders and that the firing temperature was too high (which is why it runs a bit better on lpg). I don't really understand how you can have a weak spark _and_ a high firing temperature, can anyone explain this?
They reckon the next thing to do is take off the heads, check the valves, maybe regrind the valve seats and check the piston rings to see if they can get the compression back up. This sounds to me like opening a can of worms, and that I'll end up rebuilding the whole engine if they keep finding things that aren't right. I've just spent a hundred quid on not really getting it any better....
The other option is try to find a replacement engine, which can't be too hard, which would probably cost the same as sorting this one out, but might come with its own gremlins.
And anyone got any thoughts on getting a fuel injection engine, are they going to be much more expensive and are they more complicated to set up the lpg?
Anyway, thanks for listening, and i'd be very grateful to hear from anyone who's had the same sort of dilemna!
cheers
