I agree. If the engine has a known history and is relatively clean internally, then 5k isn't al that much. In this case though I would defintely shorten the oil interval.

Just need to keep an eye on the oil colour. 

Morning ran a country trip on the weekend about 400kms round trip. The car run fine smooth and tight on the road. Start up last couple of mornings no smoke 🙂. I will check oil regularly and we will change and flush at 3000km and may remove sump than, thanks lew

I agree. Pictures are valuable to any forum when trying to work through issues. Takes the guesswork out and gives everyone a learning opportunity.

Afternoon all my mechanic sent me some pics. There was a lot of sludge and took 6 goes of degreaser  and kero and pressure wash to clear out all the sludge, the other pics are the sensers before and after. I don't have the car back yet, looking forward to a drive and see how it is.

Good if the dealer is genuine and going to honour their warranty. Another member was in the same situation and it finally got resolved under warranty by removing the front valve cover and giving it a thorough clean.

Only If the valve train is badly sludged up would a mechanic also recommend dropping the engine pan and cleaning the oil pick up screen and tube. I very much doubt that this would be the case if your vehicle only has 100K on the odometer. 

As background information, the 2GR-FE is a modern engine design with smaller oil passages, tighter tolerances and is prone to oil sludge. This why regular oil changes using a quality full synthetic engine oil of the recommended oil viscosity e.g. 5W-30 with genuine Toyota oil filter cartridges are essential when using the manufacturer's recommended oil change interval. 

If your vehicle has not been serviced by a Toyota dealership, then the service centre may potentially have used budget quality engine oils and non-genuine oil filter cartridges. 

Personally, I use non-genuine oil filter cartridges which only have a recommended 5000 km change interval. I have been changing oil and filter cartridges at 2500 km intervals because most of my driving is short distance. 

Thanks Ashley with the mechanic now and will remove valve covers tomorrow. Will be interesting to found out how much sludge had built up.

Ashley is 100% spot on with your issue.
I suspect you've been following the stupid oil service interval laid out in the Toyota service booklet. You have no idea how many people who have, complained about about smoke or sludge issues.

Now that it is sludged up, you will need to do the engine flush as mentioned and then very regular oil services for a prolonged period of time to bring it back. Then just keep it under 10k, preferably 8K. Oil is cheap, especially when the big three outlets offer regular specials so there's no excuse for doing regular oil services.

 

Thanks Tony just brought the car and driven about 200kms previous owner not doing the right thing working with my mechanic and car dealer to resolve issue. Have passed Ashley,s answer on to mechinc. 

Thanks Campbeam I am having rockercover removed and cleaned and will increase oil change intervals. I like the idea of using oil to flush rocker cover baffle thanks mate properly still fit catch can.

Hi all just brought a 2015 GX with 1000005kms and on all start ups blowing heaps of smoke. I have read forums and believe the motor is sludged up. Had my mechanic do a flush full service and new plugs, compression is very good. But still tons of smoke. I will do more regular service 3000 to 5000km. Has any one added a oil catch can to help remove oil vapours
