Got the Bad Diesel at Unipet Station on union road Marabella.....Don't Buy Diesel there

i got some power loss in a 3.0 hilux after filling at union road marabella. this was about a year ago. i'm not going back there again

If anything my main problems with NP usually occur at Old service stations.
ymmv

some of these unipets are converted np stations. the union road unipet is an old np (>25 years as far as i can tell). similarly st augustine unipet is an old np.

best bet should be a new unipet like brentwood in chaguanas

went for 5,000km service on my Hilux today at TTTL, they didn't change the oil filter. they said the engine is designed for the filter to be changed every 10,000kms. can anyone vouch for this? if not i think i would just request they change filter every service

They are right. Depejds on the filter. Tttl sells three different types of filters

[kamakazi]

I believe this to be a very bad practice especially for the first service of the vehicle. The most amount of wear metals that an engine sees in its normal life is generated in the first 1000km. That first filter therfore has a lot of contaminants in it and to cycle new oil through that for another 5000km...
I did my first oil change at 964km; my next oil and filter change at 4996km and my next oil and filter change at 100025
From here on I will run intervals of 6000km to 8000km
Total Quartz 9000 and shell rimula R4 are my current engine oils of choice
I advise changing the filter every oil change

I must add that I would only run a filter for 10000kms if it was the made in japan Denso filter.... not the made in Thailand (they have the same part number but the filter element is different) but that's just me

[Paullct]

gonna change every service just to be safe

[Team Loco]

Whats a good hrand clutch and pressure plate? Assuming dealer has no stock?

[Rainman]

I use the original filter but still change it every 5k

Timing Belt and Water Pump Job
Thoughts: Pain in the a$$; the waterpump is blocked by almost everything in front of the engine

Man power
At Least 2 people

Tools Required
10mm Hex
10,12,14mm Spanner/Socket & Driver
19mm Spanner
22mm Socket and Driver
Pry Bar
Bucket
Torque Wrench

Parts Required
Water Pump,Idler Pulley and Tensioner
Timing Belt
Drive Belt
Coolant


My Procedure
1. Remove timing belt cover and find the mark on the cam gear that needs to line up with the downward pointer at the 12 o Clock position on the rear timing belt cover
2. Remove Stone Shield
3. Tap ignition to move cam gear mark closer to help with lining it up and you can use the 22mm socket and driver to turn the crank to line it up properly(you can use the 22mm on the crank to turn it all the way around to build muscle if you so desire;also turn in the direction that the engine normally turns). Lining up the top mark should also align a notch in the lower timing gear with an arrow at the 3 o clock position.
4. While the 22mm driver is on the crank bolt you can use it to hold backup to break the 19mm bolt holding the cam gear in place.
5. Find the Radiator drain plug on the base of the radiator near the driver side and drain coolant into the bucket
6. Disconnect the Battery
7. To remove the timing belt start by breaking the bolts holding the tensioner in place and use the hex to break the bolt holding the idler pulley in place; remove the bolt at the bottom of the tensioner which would cause the assembly to move enough to make belt removal easier...unbolt the tensioner and the idler pulley(note that there is a washer behind the pulley; careful not to drop it)
8. Remove air Filter box
9. Removing the drive belt is best done as a dual effort; You need to break the bolt that holds the pulley which presses the belt downwards between the AC compressor and the Fan/Waterpump. The tensioner is the lower most pulley which pushes the belt upwards between the alternator and the crank. Someone has to pull the tensioner to the driver side(use the 14mm spanner) while another removes the bolt and the pulley.
10. Remove the fan and the drive pulley as well as the drive belt
11. Remove cam Gear and the Woodruff Key
12. Remove Rear timing belt cover

Now the Water pump has 7 Bolts and 2 Nuts holding it in Place
-1 nut and 1 bolt are behind the rear timing cover
-4 bolts and 1 nut are easier to get to at the front of the water pump
-the last 2 bolts believe it or not are clearly visible but also holds the alternator bracket to the block

13. Moving Alternator requires the removal of 2 Bolts that also hold the water pump in place at the front and 2 bolts at the side. The final bolt is on a small bracket below the alternator but when we were going to remove it we found that turning the bolt moved the alternator out of the way.
14. Place the bucket below the waterpump area as well as some rags as more coolant is on its way out your engine
15. Clean up and start the install process...its very similar to removal only difference was that for the installation of the new timing belt we put on the tensioner first then the belt and we put in the idler pulley last...we also reinstalled the old parts just to hold backup as we tightened the cam Gear bolt to around 75ft. pounds

Used a rivet and a C clamp to reset the old tensioner
We also had to change our cam seal as we discovered a very small leak
Filling back the coolant takes a while and i was too lazy to locate the bleed bolt
I am also aware that there is a place on the cam to position a monkey wrench to hold it steady while you tighten the cam gear bolt but laziness again(requires removal of the cam cover and that requires removal of the pipe where the intercooler would sit in the 3L...too much headache)

Thanks to Filterproz for coming through with the parts
I saw pictures of a 2 piece waterpump...I will be requesting that one for any future repairs....the one piece design is pressure

We took the entire weekend to complete it but total work time was about 16Hrs (It took us longer to understand the setup as we had never worked on it before but there were pictures online which helped). World cup games and 3 trips into marabella to get the right drive belt and the Cam Seal also kept us back a bit

[Team Loco]

Wow.

I in some pain right now. My pilot bearing shelled and gearbox is locked in place. Right now we got two chain blocks on the gearbox to try to yank it out. All other alternatives exhausted. 2004 sr5

Been reading tru this whole thread and you guys only talk about the diesel engines the 1KD or 2KD ,i my self drive the diesel Hilux vigo 4x4 3.0 and the gas 2.7 vvt-i 4x4 my wife owned since she migrated been driving the 2.7 more was going to sell it but change my mind ,i can say the power of the vvt-i and speed almost the same, then is the maintenance , just tuned up the 2.7 yesterday and cost less than the diesel ,10w 40 shell HX7, oem oil filter and sprayed out the TB. Last tuned up on the diesel cost more, all oem parts diesel oil , oil filter ,air filter, fuel filter,service injectors . Yes you get better mileage out of the diesel but to maintain is more than the gas engine , were as the the gas is less maintenance but you pay more at the pump.

Then it's about getting bad diesel , servicing the pump and injectors ,turbo problems in my opinion i choose the gas hilux .

saw a gas hilux in tttl doing 325,000 km with only basic tune up

[kamakazi]

No love lost for the gas Lux but there aren't a lot of them and TTTL stopped bringing them (I think)
As regards servicing your observations are correct
Diesel Engine costs more to service than the gas engine you just pay more at the pump
My only gripe with the gas engine would be the oil filter location

I have mentioned this before but if the difference in price between a gas powered vehicle and a diesel version of the same vehicle is greater than $20,000 (diesel vehicle being more expensive), I would seriously consider the gas as $20000 buys a lot of fuel (super)
Insurance premiums and service costs would also be lower.

In the case of the 2006 model lux the 2.7L gas was cheaper than the 3L diesel by about $50000 (both auto with similar kit). That's fuel to cover 185000Km (calculated with super at $2.70 a litre and 10Km/l consumption) not even factoring in savings on premiums and service.

As regards Information on the vehicle I would advise checking TacomaWorld as some Tacomas carry a similar drivetrain as the local Gas Lux

[Xplode]

Just came back from a south run with the gas lux ,tank was filled up from half ,reach gulf city and back town side took $12.00 super unleaded top up ,ac full blast and moderate driving ,so the guys who saying the gas lux is a gas drinker they are wrong ,do the same 2.7 vvt-i engine comes in the prado also ?

next planning to do some off road weekend .

[droppa]

Gas lux is sweet, the 2.7 vvt-i pulls 33" mts nicely, jus as good as diesel, yes there will be power and economy differences, but none the less, strong engine, stood up to a overhead well!

I did this one recently, 3" body, 3" suspension, 33" Bighorns, 10" wide rims!

[Xplode]

droppa how much the whole mod cost ,sweet

another thing got a new chrome bumper to replace , wife dented up one side even with sensors

anyone know were drills holes and install back the sensors .

[Ted_v2]

Forqing sweet. Saw these gas ones selling for a pretty decent price.

Besides the engine and trans. What's the difference between models?

[kamakazi]

↑ not sure about the passenger side airbag

[droppa]

From what I've seen everything else is the same, van reacted symmetrically to that of a diesel counter part for all of the mods!

Price was 18k total for lift, rims, tires and wheel spacers!

[DVSTT]

I thought the gas one needed premium so I was expecting them to be cheap second hand.
Oh well....

[kamakazi]

2TR-FE (2.7L gas engine) listed as 91 RON or higher in the manual. That means it running on super normal. .... Nice

@droppa
do you have an extension on the driveshafts to accommodate the lift...I read somewhere that without proper mods you put excessive strain on the driveshafts when the vehicle is lifted and big tyres are fitted

[DVSTT]

What tyres are you guys using? Which do you recommend?

yes and the 2.7 vvt-i has timing chain other than belt , talked to a parts sales rep in TTTL ,he said plenty engine parts for the 2.7 because i quote "they don't give trouble so" and you can get 25% off over stocked , same water pump and alternator as the diesel 2.5 engine .

With a 3" lift there is no need for a driveshaft extension as the slip yolk can more than accomadate the difference... Any more lift you might need to tilt the diff and use an extension..
