ronzilla Posted August 31, 2019 Share Posted August 31, 2019 Greetings from New Zealand ! I just bought my supra 3 months ago and a couple of weeks ago when I was driving I noticed a small amount of smoke coming out the bonnet. I pulled over and found there was oil leak coming from the air intake hose ( the one that goes to the airbox ) dripped to the exhaust shield. Upon close inspection I found out the hose has multiple splits so I ordered a new hose. So today when I pulled the old hose off I noticed some oil in the pipes. Do I have to worry about this ? The car does NOT blow smokes on idle or on acceleration whatsoever and its boosting as it should. Any comments will be much appreciated. Thanks !

rider Posted August 31, 2019 Share Posted August 31, 2019 (edited) These cars are old and have usually been through a few owners by now so you probably don't have a full detailed history of the car which makes for more guesswork than anything. The turbo seals may be leaking but you say there is no exhaust smoke or they may have leaked in the past and the turbos then been repaired or replaced. It is unlikely to be excessive turbo bearing wear as you say the car runs well. If it were me, I'd just wipe away the oil, see if it looks fresh or has been there a while. Then reassemble and check it again in 1,000 miles or so. Then at least you'd know if its something or nothing. I personally wouldn't be too worried at this stage.

ronzilla Posted August 31, 2019 Author Share Posted August 31, 2019 Thanks for the input mate ! Also I just changed the spark plugs before and I noticed one of the bypass hoses under the cover ( the rear one ) has been replaced with some straight hose which has been forced into a "Z" shape which completely kinked on the bends. I'll order a proper bypass hose from Toyota on Monday hopefully it will help Cheers Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted August 31, 2019 Share Posted August 31, 2019 Oil in the pipes is normal, one of the cam cover breathers exits into the intake pipework Quote Link to comment Share on other sites More sharing options...
Scooter Posted August 31, 2019 Share Posted August 31, 2019 If it was really bad turbo seals then the oil gets down into the actual air box / air filter area ( there would be loads of it!). As advised renew the pipe and monitor, which you can do by popping out the air filter and looking for oil residue up the pipe ( now the new pipe is fully intact) Quote Link to comment Share on other sites More sharing options...
ronzilla Posted September 1, 2019 Author Share Posted September 1, 2019 Hi Scooter, I did notice a small puddle of oil in the airbox. This is the rear bypass hose that been replaced with a straight hose. Would this one of the possibilities that cause this problem with oil in the pipes ?

Swampy442 Posted September 1, 2019 Share Posted September 1, 2019 No that's not ideal, but not a cause. Like I said some oil in the pipes is perfectly normal Quote Link to comment Share on other sites More sharing options...
ronzilla Posted September 1, 2019 Author Share Posted September 1, 2019 Awesome thanks for the feedback Swampy442 ! I will stop worrying about it and start enjoying the car again ! Thanks Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted September 1, 2019 Share Posted September 1, 2019 Its natural to be a bit worried with a new car You expect to replace the odd hose now and again. The link pipes are a favourite to get bodged because they go rock hard and break when you take them off. new ones are pretty cheap Quote Link to comment Share on other sites More sharing options...
