Car Forum / Australian Car Forums / 4x4 Cars (Australian group) / March 2006Need reassurance re new LC105 4.2 Diesel with Denco turbo
I'm in Asia and not in Australia but you guys seem to know the most about diesel 4x4s so I'm posting here. I work a lot in the bush and I've ordered a new Landcruiser 105GX with the 1Hz 4.2 diesel engine. The Denco turbo (without intercooler) was offered as an option by the Toyota dealer/exporter and so being a fan of responsive high HP V8 engines....and this being my first diesel ... well ..... after reading the material etc, I went for the turbo and the vehicle is now enroute to me. The turbo was installed by the Toyota dealer/exporter, who by the way, exports hundreds of LC105's per year and probably installs these Denco turbos on a few 1Hz 4.2 diesels every month. Today I told my mechanic about the vehicle I had ordered and he was very negative on the turbo ... saying I would have all kinds of problems ... the turbo will suck oil into the engine ... the turbo gets so bloody hot it can destroy the oil running thru it ... wil reduce engine life ... the rings will come off the pistons and the heads will have to be replaced ... if I don't let the engine idle to cool the turbo before turning the engine off, steam will build up inside the engine .. etc etc etc. He's had a lot of experience repairing vehicles with turbo problems although he had not heard of the Denco turbo. This guy is an excellent all-around mechanic and what he has said has made me a bit worried about the Denco on my new LC105. Any comments? Anyone using a Denco turbo having these kind of problems? > I'm in Asia and not in Australia but you guys seem to know the most > about diesel 4x4s so I'm posting here.

I don't know that brand specifically but after market turbo installations are very common and if fitted correctly they should be trouble free. Before taking delivery make sure the turbo is covered by the warranty and the installation is approved by Toyota so your warranty won't be affected. Daryl Thanks for the comment .... yes it comes with a 3-year Toyota warranty even with the Denco turbo installed. The web site for Denco is http://www.dencodiesel.com/ > Thanks for the comment .... yes it comes with a 3-year Toyota warranty > even with the Denco turbo installed. > > The web site for Denco is http://www.dencodiesel.com/ Well you have nothing to worry about get in it and enjoy the drive Kev >> I'm in Asia and not in Australia but you guys seem to know the most >> about diesel 4x4s so I'm posting here.

It will not be covered by warranty. TOYOTA will void warranty on the engine, gearbox and diffs. This i know from past experience. This is fact irrespective of what the dealer says, contact TOYOTA direct to confirm this just as i did here in Aus Steve > Daryl > It will not be covered by warranty.

You will get people saying this is bullshit and i challenge them to email Toyota in their country and to post the full email with both addresses intact, just in case the letter is changed. then you can verify that letter with Toyota Steve Better still here it is from Toyota.com.au http://www.toyota.com.au/toyota/main/FAQs/0,4611,1370_402,00.html a.. Will the Toyota Warranty become void if I modify my car? Toyota Warranty will continue to apply to original components of the vehicle providing they have not been altered from the manufacturer's specification or impacted by the modifications. Also, the Toyota Warranty will continue to apply if your vehicle is fitted with Toyota Genuine Parts and Accessories. However, any damage resulting from non-genuine modifications will not be covered. >>It will not be covered by warranty. TOYOTA will void warranty on the >>engine, gearbox and diffs.

Daryl I'm not worried about the warranty. It's in writing on the Toyota invoice which also includes the turbo installation as well as other TJM accessories. Being on your invoice does not mean you will have warranty on it, i think you better get professional advice as i think this is beyond you. steve http://www.toyota.com.au/toyota/main/FAQs/0,4611,1370_402,00.html a..

Its possible that the dealer is warranting the vehicle and Toyota have nothing to do with it? I've seen some ads for aftermarket turbos that state they will cover any warranty issues that are not covered by the vehicle manufacturer so maybe thats the deal? There also could be different rules in different markets, what applies in Aus may not apply elsewhere as other countries may have different legislation regarding warranties. Daryl Daryl Are they GENUINE TOYOTA PARTS? If NO then your warranty will be void, none existant, not applicable, zero, zilch, caput. However, any damage resulting from non-genuine modifications will not be covered. Can't get much simpler then that Steve So you saying that if you buy a toyota with a so called factory turbo is covered by the warranty but if he gets a turbo fitted not at toyota but buy a toyota wanna a be the its not coverded!!! Well what the frig is the turbo thats factory and the one thats not ???????? NOTHIN there both aftermarket, factory tubo's on toyota are not stamped toyota and as for denco turbo's there more siuted to the 1hz engine and if ts fitted via toyota to there spec wich intails 7 pound boost at 2500 rpm and nothing more and toyota arrange this they have to cover it unless they have stated otherwise on the contract of sale of the turbo install, and as for gearbox's and diffs 7 pound is nothin in the rite hands and F??KED in the wrong hands!! as for oil burning and rings falling off i recomend seeing a qualified diesel fitter and a qualified turbo fitter but its ordered and on the way so its a do or die with toyota I have had toyota'a for many years and ya hear the ODD story of people who have had problems with warranty's and others who have great results. no matter where you go or what you buy unless you read the fine print its likely NOT COVERD > Are they GENUINE TOYOTA PARTS? > [quoted text clipped - 7 lines] > > Steve Hey Steve, relax and don't worry about my warranty. I don't use the normal neighborhood Toyota dealer OK? Read Daryl's post again. My warranty is not above me. I know exactly what I'm doing. This isn't the first vehicle I've bought from this supplier ... it's just the first turbo diesel. But I'm the first to admit that I am lacking in diesel turbo knowledge and I wanted to know more about this turbo for my new LC. So thanks guys for your comments. I can sleep tonight knowing I didn't make a big mistake :p In defence of my mechanic I should say that the turbo diesel engines he's worked on have probably been the older ones and the way vehicles are normally maintained/neglected here, he's probably seen the worse of the worse. So I now have a chance to educate him on the benefits of a modern turbo diesel engine which is properly maintained. ;) Any more comments or advice are mose welcome. ok now worries i thought the warranty may be a concern 4 u.

[quoted text clipped - 25 lines] > > Anyone using a Denco turbo having these kind of problems? Sounds like a fuckwit to me funny how there are thousands of turbo diesel conversions done to the 1Hz here that have had none of those problems what makes me suspicious of him is "if I don't let the engine idle to cool the turbo before turning the engine off, steam will build up inside the engine" the cooling of the turbo will take less than 1 minute to do, so stopping and turning into your drive, opening the garage door and parking will be plenty of time, you can fit a turbo timer if you are worried but I don't know of any factory turbo diesels fitted with a timer so I can't see it being a problem, what it will do it help your turbo last a bit longer, will do nothing to the engine or hurt it in any way, why would there be steam in the turbo????????? Turbos don't suck oil unless the engine(worn rings) or turbo(seals) are stuffed but seeing as yours is new this WILL NOT be a problem "the turbo gets so bloody hot it can destroy the oil running thru it" so how does he explain the millions of turbo diesels running about in the world for the last 80 years? it will be fine and if you are worried fit an oil cooler if one is not already fitted with the turbo kit "the rings will come off the pistons and the heads will have to be replaced", HUH???? I don't think he has as much experience as he is telling you find a truck mechanic that deals with turbo diesels everyday and ask them, I don't think the brand of turbo will change any of the above either Kev |
