For 2.7TD ~1990 engine:

Adjusted valve clearances on rockers to 0.356mm
No. 1 cylinder TDC, comp stroke, do valves 1,2,3,6
No. 4 cylinder TDC, comp stroke, do valves 4,5,7,8


Rattling engine now smooth as!
Is an easy job too :)

oops, been posted already.. although the manual i have specifies this different clearance to the previous post.

Nice Terrano! good to see there are some out there getting mods, I have a non turbo 89 model 2 door, looks nowhere near as nice as yours with the chrome grille and bumper, recently had to do some paint repairs due to an acid rain incident, has a 1 inch suspension lift (sagged 2 inch lift apparently) and knackered shocks so they are first on the list of replacements, after that i'm planning exhaust/extractors to open up the top end (hah) a little bit.

really like the black 4 doors though! :) tempting to sell mine and find one but manuals seem to be few and far between.

Cheers for all your info.

Dom.

Now that my arse is covered :)

For those wanting to scrap the EGR on their TD27/T, it should actually be quite simple.

Haven't done this myself, but have a copy of the service manual handy.

Looking at the inlet manifold on the water pump, there are THREE water temp sensors.
The one closest to the front is for control of the EGR system, and nothing more.

In supplement to my post above - if it does result in an engine error code, simply place a 3.3kOhm resistor in place of the water temp sensor - will make the computer think that the sensor is there, but it won't meet the conditions to open the EGR valve.

Hey guys new to 4x4ing all together and i recently have bought my 1st fourby a 1987 2 door nissan pathfinder with a z24 engine in it. I would like to know what are the basic mods i should do to this car? Also i went to my local ARB for a 2inch lift kit they said the best they can do is a 30-40mm lift in the front and a 2inch coil lift in the rear. Reason i am askin is because i would like to fit some 31's under my vechile

For anyone interested in modifying their WD21 - It is possible to get a 3" body lift engineered in WA. I applied for it a long time ago and was granted approval in principle (just required an engineer's sign-off).
Went with a 2" lift anyway.

Disconnect it, and see if you can run the car as per normal without an engine error code.

As I haven't tried this myself, I don't know if this results in an error code or not.

Give it a go though!
An alternative - same disclaimer- is to remove the vacuum line to the EGR module from the vacuum actuator asembly on the driver's side mudguard under the bonnet. Just trace it around to ensure you have the right tube. Plug the hose and then marvel in the lack of exhaust smoke, the vastly cleaner oil on your next oil change and the slightly improved economy. Please don't ask me for pictures as I no longer own the car and thus can't take any.
Haven't owned a 2WD since 1982.

Does anyone know how interchangeable the thermostats are for the 4cyl/6cyl Petrol engines and the Diesels?
We've determined that there are two thermostats available for TD27/T engines - which open at 76.5 degrees and 82 degrees, respectively, but I just found a Nismo Thermostat for (apparently) V6 Pathfinders (WD21/R50) that opens at 62 degrees.

There seems to be a lot of confusion about water pumps for the TD27T/TD27 motor.
I've read numerous things across a few forums and none of them actually make sense.
So, I will share what I have learnt from first hand experience:

Yes, there are two water pumps for this motor.
They are not a "normal" and "Australian spec" difference.

Up to 1992, the TD27 in the AU Navara was fitted with a fan hub with 135mm bolt spacing.
After 1992, it used a 143mm bolt spacing.
The TD27T in the Nissan Terrano (import) has always (as far as I can tell) used the 143mm bolt spacing.

Water pump with 135mm fan hub: WP3028
Water pump with 143mm fan hub: WP4130

These are Gates pumps made in China for Repco.

If you need to replace your water pump/fan hub, check the bolt spacing first! It may have already been replaced with the wrong one, who knows!

Also, if you're planning to replace it, it may be worth having a heli-coil kit handy! :irked:
