The V8 Owners Forum -

When I say the oil was thin, I may have understated the dilution!! What came out of the sump was 6.5 litres of fluid with the consistency of water when it was cold. Having mentioned that, it's true that the tappets did not appear too knackered when I looked at them with the inlet manifold gasket out...

Thanks for the points above. I'd already discounted the worn needles, as both carbs appear to be almost new, but the fuel pressure is one of the things I was going to measure again. I measured this with the engine static some time back, but it has occurred to me that the pump may well be packing-up,...

I've posted on the LPG forum, similar sort of issue with a LC ex-military V8 running in a RRC. The conclusion I came to was that the cams are fine (I had a look when I had to change the inlet manifold gasket for the second time in 12 months - first time to fix the leaks built-in by Landrover, second...

The plot thickened a bit more last week, when this RRC turned back up on my doorstep again. This time it was really running badly, so I took the liberty to replace all the pukka NGK BPR5EIX plugs with the conventional NGK BPR5HS units - and the quick minded will spot the glaring error that this poor...

Sounds like the LPG stepper motor input from the TPS is missing, so the motor is behaving correctly for a "closed throttle" condition. Do you have any kit to look at the TPS signal into the engine ECU? That would eliminate or highlight whether the TPS or LPG circuit was dodgy.

An uprate to 9.35:1 pistons and a pukka "standard" camshaft was the option that I gave the chap, when all else fails. As it happens, I have been able to tweak a bit more out of the current system, to the point that the vehicle will just about pull at WOT mid-engine-speed (as long as the skin on the ...

Thanks for the comprehensive description and pictures! From the sound of it, the closed-loop system that you have employed could be a bit further than the chap who owns this particular RRC wants to go. It is, I have to say, the most logical way around the whole issue. One thing that strikes me is th...

My Dad's 110 is an 8.13:1 and that runs fine on gas, in fact I am currently driving around in it while I change the front axle on my 90. His 101 also runs on gas, I think they have a weird (but again low) compression ratio compared to other engines - 8.25:1 I think? Yes, in both cases the 101FC and...

Hi there, I'm a newbie to this forum, but I have had an ongoing issue for some time now. Years ago I made the mistake of taking a "short-cut" to a rebuild on the wife's RRC, and I sourced one of the NOS ex-Gulf low compression V8's that were on sale through various independents. To cut a long story ...
