Diesel/LPG.....ratio of use and air filters

Roachie,

My Chev has an air filter on top of the engine. It doesn't have a Donaldson Pre-Cleaner. Yours may be the same - reading your description of "how to get the air filter out", it sounds about as 'easy not' as mine! I normally do my own servicing and it's a bitch to get the air filter out of it's container drum. It was even worse when the converted truck was first delivered from Brunswicks - to get the air filter out, I had to remove the drum from the engine. To remove the drum from the engine, I had to get at the strap bolts at the rear of the drum - it is 99% impossible to get these strap bolts out. To make this a bit easier I removed the whole flamin' kit and kaboodle from the engine - brackets 'n all. I picked off the spot welds and turned the straps around so that the bolts are at THE FRONT and welded the straps back on. That way I can undo the drum retaining straps, remove the filter and replace it. It's still a bitch, but now it's only a little bitch. Yes, I still have to remove the large diameter air inlet hoses. I remove the "U shaped" one on top and the one underneath that. I do not remove the end that goes to the inner wing panel (and then on towards the snorkel inside the wing). This whole shooting match is an ongoing mod until I make it easy to do.

The mechanic at Brunswicks reckon' he can get the air filters out WITHOUT removing the drum from the engine. He does it by 'bending' the plastic blades on the filter element and by "pushing back" the air con piping and associated brackets. A bit rough I reckon. There's gotta be a better way and I WILL find it! It shouldn't take 30 minutes to clean a paper air filter for God's sake!

I'm running a paper element - part number is - schit!!!, the trucks in the panel beaters and the filter part numbers are in the truck - I'll get it for ya tommorow when I get the car back. Wife backed it into a BIG tree!!

The K&N filters will let the engine breath better but I wouldn't use a K&N in the bush. City maybe, but not in the bush. A lot of Chev owners switch filters from K&N to standard and back again as they to 'n fro from the city to the bush.

Re the gas fitter - phone Brunswicks (08 97261431) and ask to speak with Scotty or Greg Jones himself ( he owns Brunswicks), tell 'em your dilemma with the gas. They will be only too pleased to help out. They're a great mob to deal with. 30% gas sounds way too much and I'm surprised that its not running a tad hot from overfueling. Just shows how much abuse the Chev will put up with eh?? 8% to 15% is about right.

Hope this helps mate,

Just call me if ya need any more,

Hey! you two. Just get a JEEP each and we won't have to read/listen to this V8 'hissan-nissan' diatribe.

Maybe a nice big Toyota air box would be the go, or a nice plastic JEEP one that has two clips and takes 20 seconds to open, remove -replace filter and shut.

Keep it coming Roachie, I am just hanging on every utterance re this new monster you have by the tail. Hang on to it real tight mate.

ROFLMAO with copious tears in eyes and sore sides.

PS

What did you do about those two big mother of holes in the snorkle. That may be a clue to the LPG/Diesel ratio thingy.

My old 81 Datsun b-bird that I put on LPG gave me all sorts of grief/excitement when I dual fuelled it in 1986. 12 years of R&D later I finally got on top of it along with the consulting mechanic/techo's. I still have it and it HAS run 100% lpg
since 1987.

Roachie,

K&N is the worst filter you can use .. in the US with the bigger engines nobody in his right mind uses a K&N only unless they don't know better ...

K&N does not retain as much dirst as it should and the flow is also way less than others .. I have purchased paper filters for town use for mine and AC Delco when I go in the dirt .. I did that on recommendations and test data and do not have any own experiences yet since my truck has not arrived yet ...

The 30% I guess is the max and probably not an average gas consumption although I think the gas systems now aim even higher. Let us know how you go with the gas ... I was thinking about it too for mine, but first have to see where I fit all my extras and still have space for a decent size tank.

Have fun

Whatever you fit make sure it offers no restriction to airflow, these engines need lots of air. Mine has 4 inch ID trunking all the way before and after the Donaldson air cleaner.
Steer clear of foam filters if you intend to keep it for any length of time they do let lots of fine dust through, paper does a much better job.

I have diesel/gas on 4.2 Patrol. My understanding with the gas is 0% at idle and up to 30% under load. This averages out at about 25%. I have 180l diesel and 60l gas which runs out about the same time.

Which reminds me of a story,,,,,,,,,

A good few years back a workmate of mine retired and bought a Landcruiser and a 16 foot van. Off he went from Perth, up around the Pilbara and The North West.

He was about 80kms from Nanutarra Roadhouse (yes THAT place of pirates and brigands) when he came across an old Datsun ute towing a 6 by 4 trailer full of camping gear, broken down on the side of the road. My mate stopped and spent a few minutes trying to get the ute going again. He's a vehicle upholsterer by trade and not a mechanic so they didn't have much luck. So the ute driver asked if he could tow him to Nanutarra Roadhouse. My mate didn't want to leave his new van on the side of the road so he thought about for while, asked his missus and finally hitched up the ute AND it's trailer to the back of his van!!

And off they went!!

He'd been going (slowly, slowly) for a while when he noticed that his Landcruiser and it's "road train" were going faster uphill than it was downhill!! Strange, thought he???

After about half an hour he stopped and walked back to the ute and asked him WTF he was doing to make it go slower downhill than uphill.

The ute driver replied that he was putting it in gear and dropping the clutch every once in a while to see if he could get it going by tow starting it!! BUT he didn't want to "put too much load" on the Landcruiser by doing this uphill!!

My mate went ballistic!! Damn near strangled the bloke!!

True story from the bad old days in Cowboy Land, Western Australia.

While its a different vehicle & donk i put a 6bgt isuzu into a f100 admitantly i had more room but i used a international harvester air cleaner assy.(Donaldson copy)
Just one question do you really have a a/c in the can ;)) lol
What about vertical mounting could this work in you vehicles ?
As a mechanic i would steer away from foam filters for these vehicles but thats just me. I have seen some real ugly dusted donks from these first hand.
Side access could work as well but you would need to cut body panels & make a neat access door.... hope this helps 666TOY
