Hey guys. I’ve been seeing occasional white smoke coming out of my exhaust here n there and excessive oil consumption out of my sportivo 7A FE Corolla. The car doesn’t smoke up constantly or when I floor it so I’m hoping it’s nothing to do with piston rings. What could be the issue? Oil return line? PCV valve problems?

Sounds like it could be a PCV issue. If you know how to remove it, you can give it a clean and see how it goes. You may have a sludging issue creeping into the equation.

Can I ask how often you do the oil service ?

Probably a good idea to reduce your oil change intervals if you haven't done so already. You might also need to start using a flushing agent during the next few changes to help clean things up a bit.

Hey mate thanks for the advice, I swapped the PCV valve with the stock NA one. It turns out there’s is no vacuum whatsoever in the system. The PCV seems fine but there’s isn’t any suction on it.

Funny thing was, this car burnt through almost 2L of oil in around 6-7k kms of driving. But there’s nowhere near enough smoke coming out of the exhaust for it to be a ring issue. Most likely something with the crank ventilation system

      FUEL WARNING MESSAGE

      On my 2002 Prado, the fuel transfer pump has a fuel filter which can block, causing increasingly less fuel transfer between the tanks. It may be the same for the Cruiser too. I have not yet had an issue with mine even at 250000km, but that is low mileage for a 2002 Prado. I hope that you have a filter that can be easily replaced. It could save you a pump replacement.

      2002 Hilux Engine Replacement

      Unless you can identify which engine your Hilux has now, you may be better off finding a good 5LE engine and return it to stock. Nice to have a Turbo diesel though. Have you tried taking a photo of the engine and posting it so others can advise what engine you have. It may be better to have your engine overhauled. If you can locate the engine number (should be on the registration papers if the engine swap was done legit), you might be able to ID the engine that way too. Do you know why the engine seized? It may be possible to overhaul your engine cheaper than replacing it.

      Transmission clunk

      Hi all, Recently completed a long drive. Check engine light came on, traction control off light came on, unable to use cruise control. Pulled immediately over all oil level were good and no leaks. then when accelerating through the gears ( automatic Prado ) hearing and feeling a clunk on each gear ( like it was hard to select). Prado is unable to go into 5th & 6th gear. Maxed out in 4th gear at 90km/h @ 2500rpm. Later in the drive DPF light came on though I have a July 2015 build. DPF introduced in October 2015 that I am aware off. Any ideas at all would be grateful!

      Yes, with 12v applied to the pump you can definitely hear it whirring if it is working. Kind regards Geoff

      Yaris Cross roof rack

      Hi all, I’m looking at purchasing a Yaris Cross GXL however I can’t seem to find any official roof rack for the car On the Toyota website it doesn’t show a roof rack protruding like the Corolla Cross GXL I know you can get roof racks that slide under the door however I don’t see any official listing Interestingly enough Toyota offer an official bike rack for the Yaris, Corolla hatch etc but not the Yaris Cross Rhino-Rack offer a third party roof rack for the “TOYOTA Yaris Cross Gen1 5dr SUV Bare Roof” but I’m a bit hesitant to use a 3rd party roof rack on a brand new car. Do you know if this would cause any warranty issues etc? Another option would be to get a Corolla Cross GXL. However the Yaris Cross would be perfect if it could have a roof rack as I don’t need the extra size, engine and price point of the Corolla Cross. Happy to hear your thoughts

      FUEL WARNING MESSAGE

      I've just got a price from Toyota up here in QLD for the whole replacement unit... (OUCH!!!! 😭) I would share more information on my investigation so far, but apparently, I am a spam bot and can upload pictures, but not write the story to go with it.... without being pulled up for it...... I can tell you that I am getting no suction on what I believe is the fuel line from the sub to main tank. I am however getting 13v on the fuel pump connection. It comes on for a moment before going off. I'm guessing because of this error. Perhaps the rail stops delivering power..... My next step is to apply 12v to the pump and see if I can hear it in the tank making any noise. Surely, I'd be able to hear something with the car not running - if it is working?

      Hilux 2.7 1998 has knock in motor

      A recently purchased 2.7 hilux seemed okay, but when started up (warm) a clunk happened then a loud knock started. The coolant drained out, perhaps into the engine, but being unfamiliar with the vehicle I am unsure what has happened. Any suggestions and possible remedies would be appreciated. Higgyboys

      2017 Kluger AWD. Noise in Cabin - Bearing/Diff. Not Sure.

      Chiming in from the States here, I have a question. I am assuming your Kluger's have the same UA80 transmission as we do? When you say the transfer case was replaced, was it the physical "transfer case" or the transmission? We have similar issues here where the UA80 starts "whining" needing a complete transmission replacement.
