Thanks chaps, Gaz I appreciate the snorkel isn't water tight... I've got several tubes of tiger seal!!!

I had an intermittent starting issue. It turned out to be the starter motor. |

I did consider that but I'm pretty sure it's the ignition, seems to be a weak point on these, I'll give it a good clean and see if that helps... Pete

Which snorkel would you plan to use and where would you seal it too on an L322, even the G4 had no snorkel due to location of air intake... |

I know is not straightforward and I haven't fully explored the issue, the l322 intake appears to be at the front of the inner wing, same place as the Disco, need to fabricate pipe work from there back to the snorkel which should fit without too much modding, the screen angle is the same and it has clearance for the clam shell bonnet, I've successfully used water pump intake hose before as this doesn't collapse, and you can heat it and bend it a bit... Then it's just a matter of sealing the original intake....

Spot on topic, been reading with interest. Although will not be using ours for off roading, found loads of tips for repairs, etc.

Thanks Guys,
Seems to have been fine since although the alternator is only putting out about 14.0 volts, I thought it should be 14.5 so I'll keep an eye on it... Had no more trouble with the ignition since I stripped it and gave it a good clean, I also removed the solenoid plunger that stops you turning the key, and whilst I was there I removed the gearlever lock so you can now get it out of park with the ignition off.. will only start in P and N as before and you still have to press the brake to get it out of P and N, so no safety issue in removing it... Finished making the buck for the snorkel, there is not much room between the inner and outer wing at the front so I have made an elbow that fits in the space and will give the maximum airflow possible, I'm confident it will work and will check it when my brother has taken a mold off the buck and made the elbow, he wants to do it in carbon fiber but as you'll never see it fiberglass will do.... Then the latest issue reared it's head yesterday, very lumpy tickover, surging from 500 - 1200 rpm then dying altogether, restart and sitting at 500rpm.... then surging, then dying.... read the codes and it had a "MAF" fault and a "throttle valve adaptation spring test failed" fault, cleared them and it was better for a few mins then started playing up again and this time there was no response to any throttle imput... was as if the accelerator had come unplugged.... only code showing was "throttle valve adaptation spring test failed" so I presume the MAF fault was a result of the throttle fault... Did a bit of googling and it's a common fault with BMW's but has a multitude of causes... culminating in a very expensive new throttle body... So started at the beginning and checked for intake leaks and any other obvious issues, none found... unplugged the throttle body and the plug was very tight and I had to lever it off... didn't seem to have any corrosion inside but the pins are so small and my eyesights not getting any better... I gave it all a blast with contact cleaner then the air line, plugged it back in and started it and..... fixed, runs like a sewing machine, no issues at all..... couldn't quite believe it so went round every other connection I could think off and cleaned all them as well, still running great, took it for a drive, still great, no fault codes coming up.... this is the plug if the same happens to you...
Whilst I was looking around the engine bay I removed the rear heater air intake to check the PCV pipes and found this wedged in the scuttle.... does anyone recognise it, it is alloy, no thread inside and has a rubber "O" ring seal...
I did chicken out on a bit of off roading at the weekend, I don't usually do pay and play days, you tend to get carried away and break something... anyway a mate arranged a day and it was to raise money for Macmillan Cancer Support. Went along and paid my money then jumped in a mates truck to have a look around.... well it had just rained for 12 hours over Friday night so was a bit muddy..... So there was no way I was taking the FF in there....
Yes I know I'm a chicken but imagine how long it would take to clean it.....

Cheers Paul
You can see here the limited space, the plastic wheelarch cover shows how close the outer wing is to the inner wing
Next job was to make an elbow to take the inlet back to the snorkel, the hole in the inner wing is around 3" diameter, but a 3" hose wont fit inside the inner wing so I made up an elbow that used the entire space available, the outer wing reduces in size from bottom to top and from front to back, I made this to accept a 4" intake pipe that is squashed to an oval inside the wing and I was hoping would allow enough airflow. First rough mockup
Then some cleaning up and filler work, a quick check on fitment, it has to fit within the inner wheel arch plastic trim and it just does
Finish it off to a standard that is easy to take a mold from
Then take a mold off it to produce the final elbow, I didn't want to use the buck as it had got rather thick to get the correct shape and was made from plastic, filler and fiberglass....
Then made the final elbow, doesn't have to be as polished as the buck....
It has to be this weird shape to maximise the airflow
Fitted to the car
Then fit the snorkel to the front wing, out with the drill and jigsaw....
I had to enlarge the hole to aid fitting as it's so tight and forgot to take a pic of it, just maximised the size out to the fitting holes... Also fitted the grill and cut this as well....
Then fitted the new elbow with the air inlet pipe, this is two layered silicon hose with a metal spiral so holds it's shape and is bendable.. Used Tiger seal to attach and seal the elbow to the inner wing
Then refitted the wing, pulled the pipe through the hole and fitted it to the snorkel, then had fun trying to get behind the wing to bolt the snorkel to the wing with the pipe in the way, was rather fiddly but managed it in the end. Had to make a bracket to fit the top of the snorkel to the "A" pillar, it was missing, made it go underneath the "A" pillar trim so as to keep the door seal working as it should. Cut a small slot in the trim to fit it...
And that was the fitting finished.... then on to the aesthetics, not that they look that nice anyway, more function than form but this one had "Discovery 3" on it and it looked a bit funny with half the "so called" air intake vents poking out from underneath...
So to neaten it up I ground off the logo
Went over it with the D.A. sander
Also sanded off the awful plastic flash line it had all the way down the front...
Then plastic primed it and painted it with truckbed liner, hopefully it will last, moved the side repeater to the cut out (this is for the wheel arch on a Disco) and painted the side vents body colour which I think looks better....
Painted the other side vents as well... The finish looks better than standard but this is one of those cheap Chinese copies..
It takes some abuse off road and gets smacked a lot but is very robust...
I had done some testing of the short term fuel trims before fitting it all so had something to compare with to see if the airflow was restricted, at 70mph they are between 1-2% higher so this would indicate it's getting a ram air effect at this speed and is in fact getting more air in, there is no noticeable drop in performance in acceleration. I fitted the innards of it all whilst visiting my Mother during the week as my brother was around to help with an extra pair of hands and it is about 220miles from where I live... It used slightly less fuel coming home than it did going so I think the airflow is fine.... If you cover the top of the snorkel it sucks in the pipework and stalls the engine so it appears to work well.... Off to the Lake District in September and there are some decent river crossings there so that will be the test.... Rocksliders next....

The starter motor has been screaming like a scalded cat for the last few days, working OK and spinning up well but sounded like a dry bearing, took it off to have a look and found this....
And about half a cup of water looking like this (there was a lot more than this bit)
The solenoid was full of it as well
I was totally stunned that it still worked at all, it got in this state from water ingress from sitting in a river for a while, some 7-8 weeks ago. It has been well sealed up on the outside, there is silicon around lots of it and rubber "O" rings on the main body, it also has a breather attached which runs up to behind the heads... so they decided to make it waterproof...... apart from the inside where it is open to the bellhousing...!!!!! water has got in here and is then unable to get out.... It's now gone in the bin and I'm waiting for a replacement, should be here tomorrow... It sits below the standard advised wading depth so, if like me, you go plating in water then beware as yours may suffer the same.. I am going to drill a small hole in the underside of the replacement to let the water out..... see how long this one lasts..........

Pete, keep up the good work fella, I love your updates and wish I had the time/mechanical ability to fettle with my RR to the same extent (taking the drivers door card off for the 3rd time this weekend to hopefully finally sort drivers door central locking which hasn't worked since I replaced the exterior door handle cable....) |
