Evening,
I think I may have tracked down my misfire issue. After playing with all the ignition system and scratching my head a lot, I had both Rocker covers off today and I have NO movement whatsoever from the Inlet On Cylinder number 1. The plug is also completely soaked in fuel...
So, after I've delved In Im sure I'l find a ruined Cam and followers. So will need replacing, Not sure whether to go for a standard EFI cam, which I assume would be the standard original fittment to this engine (early S1 V8, so plonked in straight from the Sd1), Or for something a bit fruiter. Suggestions would be nice! Don't want a Race spec thing or something that will cost me a pound a mile/smile.
The other big question is with the bonnet removed, is there enough space between the engine and the front of the engine bay to pull the cam out? Meaning I wouldn't have to remove the engine ( Please )
Any help would be greatly appreciated.

Cheers for the reply, seen you've been tracing a misfire swell on your 390, might be worth a check on the movement if you haven't already! Wish I'd looked sooner! The thing with the upgrades really, is that a standard EFi cam with followers and all gaskets etc is looking like £150: http://www.rimmerbros.co.uk/Item--i-ETC6099K2 Good value really.
But the Kent kits are more like 600... Its up to my waller really! hahaha

Must say for the price of this Kit I'm tempted: http://www.rimmerbros.co.uk/Item--i-ETC6099K2 Not genuine Rover/Land rover, but has anyone had any experience of one of these?
Yeah the car has misfired since I bought it, Glad to finally track the bugger down! Compression test didn't show much of a drop funnily when I did it 3 or 4 months ago, only about 20 Psi. But speaking to Bradley with his white series 1 (ours our 1 after the other of the production line as far as we can tell) his PSI's were up in the 170's where mine peaked at 145, with lowest at 120 i think. so actually a fair difference I suppose. Haha!
Glad to hear it can come out in situ. means I can start getting on with it soon hopefully.

Cheers guys, helps!
Ok something like this might be a good one then? http://www.v8tuner.com/product.php?id=637 I'm thinking it might give a little more or it may bring it back to the standard 190 if Vittesse had a different cam? I'd have thought it had if its 190hp over 150?

Just seen that recommends the valve springs to be changed:
The Site lists them http://www.v8tuner.com/product.php?id=87

Ok Nice, getting somewhere now. It would be easy to put a standard one in, but I believe I've got stage 3 heads on the car. Easiest way to check? Going by JE's guide there that Ziga just posted It looks like it should come with double springs... so I may be set up to take the bigger stuff ( mind I might go for that real steel one).
I want to get it right for sure, and I want to be happy knowing the engine is spot on, so I'll take my time.

, heads look great and have clearly been off recently, I'm hoping to track down the previous owner this week and give him a call! 
The receipt I have in the file is for 'ACT super flare' trumpets, il have to get back to you on that! haven't had time to keep stripping tonight so maybe more tomorrow!
Does anyone else agree on the valve springs being double? I read somewhere that some heads have an inner and outer spring so i may be wrong.

Hopefully I'll get some time tonight or tomorrow evening to make some progress! If I'm honest the Viper series of Cams are taking my fancy from RealSteel. The look Good value and I have heard good things about them. I'll find out what I have in hopefully very soon.
Yes I will be doing the cam myself so with the saving of garage costs I may as well spend the balance on a better cam!

Evening all, been a while since I've had time to get on the car! In the last few weeks I've been moving out of my Mondeo (the reliable beast) and have stupidly bought a gas guzzling 1990 Audi Coupe Quattro 20V. HA
Well I've managed to get into the bugger:
You will find it difficult to see, but the lobe on the Inlet for Cylinder number 1 is no longer a lobe:
Going to plod on this evening and remove as much as I can, Cam out being the ultimate goal.
Does anyone know how the cam is fed with Oil? It's not obvious to me so would be great to know if someone can enlighten me!

Yeah, what a coincidence, Mine was still showing compression at 120 Psi, with rest at about 140.
Just managed to remove the rockers and push rods but cant remove any of the followers as they are bell shaped so will have to be removed from underneath when I remove the Cam. Hoping I'll get a chance tomorrow! Shows that the cam and followers are obviously due a change. the old 70-80K miles seems to be making an accurate measurement of mine at 81K!
What cam have you gone for in yours?
Noticed on top of the followers a small thin channel that looks like that might be where the oil trickles through to lube the cam lobes. Don't quote me, but thats my theory so far!

This thread has some good input!
Managed to get the Pulley off but we're struggling to get the front cover off, looks like we've got all the bolts out including the two sump bolts. Any secret ones? It looks like its never been off! or not for a long long time. The right hand side (when looking at the front of the engine) seems to have broken away but the left is stuck fast.
Any hints would be great.

Cheers,
Found the last one, it was covered in stuff so didn't see it! Cam will nearly come out but were going to have to slacken the engine mounts and just drop in half and inch to pull it out. Should then clear the bulkhead and give us decent space to replace with the new one.
In regards to oil change during the job. We're thinking we'll change it now, as the sump gasket is ruined and with a lobe warn off theres probable some swarf in the engine. Would it be advisable to changing the oil again after its run in? thinking of using some 'carlube' stuff to run the cam in and then buy decent stuff after. 20w50?

I'm afraid things have escalated a tad.
Engine is now out:
So the camshaft job is now a full rebuild. Brill.
Part of me is looking forward to it, means I can lather up the engine bay and clean it a make it all nice. Paint the odd bracket etc.
Will do the mains, big ends, and rings probably. Camshaft bearings don't look perfect either, whats involved in changing them?
At least I have the bad months to do the engine now and have it ready for next summer!

Manifolds are in great shape, all the bolts were loose! Its an interesting car with many different quirks. The Chassis has been modded to accommodate power steering rack at some point, I'll get some picks tomorrow! Would love to put stainless manifolds on of course. Now that this isn't a stick a cam in job, I'm going to probably really take my time with it so it locks excellent in the engine bay, paint up what I can etc, without going too silly.
Both heads are now off the car. the exhaust valve on the front and back is seriously mucky on cylinder 1 (which is the one that one that the inlet Lobe wore off on the cam) and theres also signs the valve stem seal is leaking on that and one other that side. Not great for 11 year old/4k mile heads really is it. So these will be addressed.
The photographed main bearing is the only one removed so far from the front 2nd one in I think and its pretty bad, others will be similar I'd assume. Had a big end removed too and similar again. Cam bearings look ok on the bottom but I think the upper halves either have oil discolouration or are gone too.
Fingers crossed the crank will be salvageable.
One rather bloody large problem I have managed to make for myself is on removing the heads I have managed to snap a bolt just below flush with the block face. Just one. couldn't believe it! Does anyone have any idea how I'm going to get that out? It was so bloody tight!
I'll try and get lots of pictures tomorrow as the plan is to remove the crank in the morning before I head off anyway for a fortnight.

Yes the Middle head bolt under the rocker covers if you know what I mean. None of it is sticking out which is the problem really. I went round it once just clicking the bolts off to start with so it did move, but on my second time round it snapped off just at the top of the threads, will get a pic tomorrow morning. When I took the second head off, I went round a lot more doing a lot less at a time, must have gone round 6 times opposed to twice on the first side. There seems to be no evidence of any of the thread sealer stuff I think thats supposed to be used, as on some of the bolts there is rust, so some were a pain to get off, more than others.
