Hey Guys, I have read the forum and noted that some guys went from using a 30 micron pre filter to a 5 micron after market filter and wondered if there was any issues after doing this. I am lead to believe that the the genuine diesel fuel filter is around 5 micron and was hoping to add a 2...

Hey Guys. Bods - haha, well thats a bit embarrassing that the fan has absolutely nothing to do with cooling the engine,lol. Have definitely read a few threads on here and a few youtube vids about putting a fan on the inter cooler to help keep temps down. My only real concern with that what was...

Yeah Jonney, have put bugger all k`s on it. Was thinking of getting the timing chain inspected at 100k and go from there. It runs nicely. Was just a little concerned as want to get a little more power out of it safely for some off road trips. I have done a snorkel, looking at an exhaust and...

Hey Guys, From what i can see from the pics in-front of my radiator i only have 1 thermo fan covering half the radiator and then looking behind the radiator is the engine fan in the shroud. Is there any real added benefit in installing a second fan on the other side of the radiator? What...

Hey Guys, Jonney - i am bout to hit 50k on my Nav and looking to keep it for a while. The youtube vids i have watched looked like it could get a bit difficult at times and the yd25 website has a fitting time of around 20 hours for the D22 models. I have been changing oil around 8km mark but...

Thanks so much for the replies guys Tony D22 – yeah I got the feeling that most were issues with the D40 model. Glad to hear that yours is going well. Definitely sounds like a dual row timing chain is a good idea, just trying to prioritize it in the list of upgrades. Was thinking of trying the...

Ok guys, I have been going through the forum for a while reading pretty much every thread on the timing chain issue in yd25 engines and just had a few questions that need clarification. 1. Most of the posts that i have look like they are in the year range 2008-2011 so was wondering if the...

Hi Guys, Have been looking into the whole dual battery setup stuff on here and have noticed some are even adding in a third battery. I guess what im getting at is how much electrical gear is needed to have 3 batteries? Ideally i would like to have my D22 setup with a hard canopy (fridge in the...

Hi HJ, This is gonna sound like a ridiculous question but what is at the very far passenger side of that egr tube and does it hold any benefit at all to block it over on that side also? 4x4Nav posted a picture of the tube earlier in the thread with 2 black pipes, this is gonna sound crazy but...

Hey Guys, received the blanks in the mail a couple of days ago. They look solid as a rock which is great. They were a steal 7.99 each including postage and got to me in 2 days. Picked up 2 round blanks for just in case i wanted to block off the other side, but noticed a few guys on youtube use...

Got the blanking plates today, they very bloody sturdy which is great, hope to get them installed this weekend. That's all makes sense about the pot scourer/surface area and the oil vapour. Will be one of the next mods when I get a little but more $$. Will be picking everyone brains abit more...

Hi Czechmate, Its good to know that Liqui Moly is a good brand and that it seems to be highly recommended. Glad to know that they are safe in the common rails, read a few post about certain additives were not to be used in common rails as they micronize the particles and go where they shouldn't...

Hi Bods, Looking at an oil catch can in the near future, have been searching the forum and checking out where people have put theirs in their Navs. Did you install the catch can yourself? are they difficult?

Hey Tony, Now that you mention it i have heard of it also being called a bush tune. In the process of blocking the egr, waiting for them to arrive in the post. Was hoping to try an get rid of any carbon build up already in the air system so was also thinking of a liqui moly diesel intake decarb...

Nice... will seal it in when I get them. Feel like im doing it a bit late as almost got 40,000k on the clock but hey, what can you do lol. Probably changing the thread a bit here but is there anything else you can do cheap under the hood for an improvement and improve life of the engine?

Hey Jonney, Still Got a service in a couple of weeks and want to take it out before that and if its running all good will seal it in there permanently. I don't know why im so paranoid about it not working when everyone does it, im being ridiculous I know.

Nice to know Tony. Do you treat every tank or every so often? Czechmate, yeah I was looking at that purge plus also and was wondering if anyone had any experience with it. Is it safe to just run the engine off the purge plus stuff?

Apologies guys, Italian tune up where you warm the engine up driving for about 10 mins or so then give it a fair bit of stick moving through in high rpm in each gear. Rinse and repeat a few times. Its apparently supposed to help burn off carbon deposits in the engine. Lol, fluffy dice.

Hey Guys, As per the title, anyone know if an italian tune up has any benefits on a D22? Thanks

Sorry to revive an old thread here but is Liqui Moly products such as Diesel clean and boost and diesel injector cleaner are safe for use in common rail diesel engines. Trying to keep it nice and clean for longevity. Thanks, Chris
