I used a 0.010" (0.254mm) feeler. I have used a screwdriver as a stethoscope before without hurting myself (yet), but never heard of the hose pipe one, i'll have to give it a whirl this evening. I think it'd be best if I just take off and inspect the rocker assembly, that way I can see what I'm dealing with and check that the whole lot is sound and was torqued down properly.

So I did the tappets last night, didn't see the bit about re-torquing the head down in time. All of them had no or almost no clearance with feelers. I set the clearances and now there is still a lot of valve noise. I'll have to have a look tonight for rocker wear etc. I may have to invest in one of these click-adjust things to account for the rocker indentation. Pete, I don't suppose there is any info available on the technique shown at the September twiddle day? Thanks for all the advice.

On the drive home last night oil pressure at 2000rpm was around 45psi, so I think I'm ok. Will keep an eye on it though. Thanks for the advice chaps. I'll also be shortening a drill bit this evening now in addition to doing the tappets, as I wasn't imagining the increased valve noise. I'm firmly a metric baby, so I have a lot of learning to do now I've bought a GT6. I always hated fractions at school.

Thanks for the advice, I'll check on my way home from work and let you know. I'm hoping that you are right and I'm just worrying over nothing. I know when I first got my land rover, it took me a little while to become used to all of the noises and what the gauges did or didn't do. This morning I was sure there was more valve noise than when I first collected the vehicle, but then I may be imagining it.

Oh dear. I bought my first GT6 mk3 last week and I seem to have a similar problem to the OP. At idle when I start her she sits nicely at an oil pressure of around 60 – 70psi. Once I've done around 20 miles the oil pressure drops to 20 at idle. Heat seems fine, although she doesn’t like traffic much. It's only done around 500 miles since the previous owner rebuilt the engine. It’s in it standard form, twin strombergs and as original air and oil filters. I'm guessing it's head off time this weekend, any tips on what I should be looking for? Layman's version please as I'm probably not as familiar with taking engines apart as you chaps and I'd hazard a guess that I have a fair bit less experience on my side. So on my list so far are: Oil Pressure switch Oil pump Valve spring stiffness (although I have nothing to compare to as yet) Cam journal ovality Anything else? Any hints or guidance would be much appreciated.
