Cleaning the intercooler

Hi Malcolm,

Hope I never have a project like yours!!!!!. I am certainly keen to look at the MAF before my next big trip. I was amazed with the amount of crap in the "clean" air system. I am also looking at gaining access to the turbo and giving that a clean. My MAF must be clagged up somewhat since the rest of the system is looking average. I have had the Patrol since new and since I don't have kids, this is my substitute!!! Hope my ZD doesn't come a cropper!!>

Cheers

Hi Dave

The "project" was just a matter of sticking with it. Once I got over the initial shock. Must admit some days I just couldn't even look at it - suppose that's why it took me 3 months.

This one was a one-owner, serviced by the 'mechanic' owner every 10K. His wife used it to take the kids to/from a country school.

The history of ZD30 "blowups" points to the vehicle under load (e.g. towing caravan) on highway at 100-110kmh.Mine certainly fitted that scenario.

Do you have EGT and boost gauges fitted? Most of the knowledgebases I have read certainly suggest to do it. I am in the process of installing mine. When the MAF gets oily it sends the wrong messages to the ECU which can result in over-boosting, which, in turn, can result in piston failures. That's how I understand the problem.

You need a special security key to remove the MAF sensor. I did mine by removing the 4 screws on the air intake just past the MAF sensor, unclip the air cleaner, remove and spray inside to the MAF contacts.

Hi mate,

I have done 81297K. I have had the Patrol serviced every 10,000, and I have spent the extra after big trips like the CSR on major services. I don't use much oil, but there was a bit in that intercooler!!!! I think a catch can is the next project after this.

Cheers

Dave & Shelly ,

Everyone I talk to is doing 5k services on the 3.0td , pretty sure the owners manual says something like 10k or 5k under extreme conditions , I think Oz is considered extreme !

Cheap insurance ?

Hi Glenn,

I do the 5K service myself. Can't bear paying someone to do that easy service and lose the car for a day. I have been using CASTROL MAGNETIC 10W40 and the oil is pretty clean when changed. What about yourself????

Nissan have semi - synth oil , B3005-10W40PK part number for 5ltr . Specificley for the 3.0td.

Would like to say it isnt a big deal for you in a later model Patrol , but do a search and see a few have detonated !

i have done 220,000km on mine. i brought it when it had 195,000km and dont know if it has been flushed befor. mine is a 2.8 and getting abit sluggish. what is the flushing stuff ca;;ed, or should i just use any degreaser ?

Bevan

I used those red degreaser cans from SC. Spray on, leave a few minutes and flush off with water.

Hi Bevan,


I used CT-14 as it was non-flammable. It worked pretty well. I avoided the flammable stuff because I thought when I started the engine next it might have overrevved.

Hi Trev,

Well, 380,000KM, um yeah, you might need to "give the pipes a flush" so to speak. Would be very very interested to see how much black rubbish comes out of your intercooler and pipes. I was actually rather surprise at how much came out of mine since I spoil the hell out of the young girl. It was a half day job from start to finish. I would only use bio-degreaser as the flammable stuff might give you a little rev when you start her up!!!!.

Cheers
