Dirty MAF sensor and intercooler leak

[HV2002]

Hi all
After spending the last few weeks reading through this forum trying to learn about my new ride (02, ZD30) and why it’s been lacking power, I have finally decided to get my hands dirty.


Decided to start by cleaning the MAF sensor
Followed Tony’s thred http://www.nissanpatrol.com.au/forum...ng-MAF-sensors (great help mate, Thanks )

Started by unplugging the sensor then disconnected the battery, removed the two retaining screws and twist the sensor from housing, nice and easy.

I don’t think the MAF has been cleaned in years, the wire and plate were nearly black.

After half a can of cleaning spray things looked better

Re-assembly was easy and the hole job took less than 30 minutes

The only negative part of the job was when I removed the lid to the air box to get better access to the MAF retainer I found that the air box gasket had perished and fell apart. (looks like a trip to rare spares, Thanks for the heads up Bill http://www.nissanpatrol.com.au/forum...air-box-gasket)

While waiting for the disconnected battery to clear any error codes I thought I would have a look at my intercooler and clean some of the oil from the area.

After a few minutes cleaning I found the oil was from a leak in my intercooler.

Turns out the engine cover has been rubbing its way through the core, not happy … I was hoping to do the NADS before upgrading the IC, need to re-work the budget.

Spent the next few minutes siting back thinking I shouldn’t risk driving it as is and cause further damage or worse setting of the grenade. But as this is my daily drive I decided to do a quick fix and at least reduce the amount of leakage.


So a quick rummage around the shed turned up some self-adhesive weatherproofing flashing tape, I cut a thin 10mm strip and placed it across the IC over the line of holes and gently taped it down to secure it,

then placed another strip on top to add thickness and replaced the engine cover to hold it in place.

Then fingers crossed it reduces the leak and take a test drive.

Low and behold I think it worked …. More smoother and responsive power and better spool.

Don’t know how long this fix will last so its off to find a new upgrade IC and will do a provent catch can at the same time so the new IC stays clean from the start.

Big thanks to all who contribute to this forum and the wealth of knowledge it contains.
