Milo500 Posted September 27, 2016 Share Posted September 27, 2016 Hi guys, I have finished my single from twin supra auto build, and am running 550hp at the crank safely at 23.5psi, at perfect afr with an ecu and tune...the car runs compete perfect and has no flats spots in the map...... BUT...when I was infront of a friend in his car, I put the foot down and splattered his windscreen in engine oil that came out of the exhaust, hence it bein red (titan pro s). I compression tested the engine before the tune and it has 155-158 psi in all 6 cylinders, and the turbo is a brand new t4 88mm turbonetics...so oooo, what could this be guys? Cheers in advance on any feedback Quote Link to comment Share on other sites More sharing options...
inazone Posted September 27, 2016 Share Posted September 27, 2016 Could be atf fluid coming from the gearbox breather if it's red in colour. Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted September 27, 2016 Share Posted September 27, 2016 (edited) 88mm and 550bhp!!! When do you make full boost 6500rpm? Edited September 27, 2016 by Chris Bailey (see edit history) Quote Link to comment Share on other sites More sharing options...
Milo500 Posted September 27, 2016 Author Share Posted September 27, 2016 This is what I was thinking, my friend said he was fairly certain that it was from the exhaust...the problem is the engine oil is mst define try red aswell haha, so csn't really distinguish... If it's coming out of the breather, will it damage the box? I take it means it is over filled? Quote Link to comment Share on other sites More sharing options...
Milo500 Posted September 27, 2016 Author Share Posted September 27, 2016 I was incorrect haha, is what was on there before I put the turbonetics om there haha, keep referring to it accidently as 88....it is 82mm 64 mm compressor side Quote Link to comment Share on other sites More sharing options...
Annabella Posted September 27, 2016 Share Posted September 27, 2016 Was the gearbox filled when hot? Can easily be overfilled, also if Power steering is too full that can spew under duress, happened to me and someone else on here. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted September 27, 2016 Share Posted September 27, 2016 Red fluid is gearbox Quote Link to comment Share on other sites More sharing options...
fastcar Posted September 28, 2016 Share Posted September 28, 2016 This also happens when you were sat still and reving it dude! We were stood behind you and got a face full of oil:) Quote Link to comment Share on other sites More sharing options...
Milo500 Posted September 28, 2016 Author Share Posted September 28, 2016 This also happens when you were sat still and reving it dude! We were stood behind you and got a face full of oil:) Definitely came from the exhaust then? Quote Link to comment Share on other sites More sharing options...
Axl Posted September 28, 2016 Share Posted September 28, 2016 How can gearbox fluid/ power steering fluid get into an exhaust? I would think it would more likely be coolant are you using Toyota red coolant? Quote Link to comment Share on other sites More sharing options...
Dnk Posted September 28, 2016 Share Posted September 28, 2016 If its engine oil coming out the exhaust isn't the inside of the tailpipe covered in it ? Quote Link to comment Share on other sites More sharing options...
Scooter Posted September 28, 2016 Share Posted September 28, 2016 This build did it happen because of the stock twin turbo's going? I'm just wondering if there is loads of old oil in the exhaust that is perhaps only now getting blown out? Coolant surely won't last the trip through engine to exhaust!? and spitting oil getting there would be accompanied by blue smoke from burning oil too, no?

Milo500 Posted September 28, 2016 Author Share Posted September 28, 2016 I'm not saying it is the box, but it define try comes out of the exhaust...so everyone getting aggro saying that if it is red then it has to be the box, the titan pros engine oil is fairly red in colour. It spits when stood still aswell Quote Link to comment Share on other sites More sharing options...

No it wasn't and the exhaust is brand new when I did the conversion, also I agree with you with the coolant haha, definately eouldn't make it to the end of the exhaust before burning off (and no I am nt using red coolant) Quote Link to comment Share on other sites More sharing options...
Milo500 Posted September 28, 2016 Author Share Posted September 28, 2016 This also happens when you were sat still and reving it dude! We were stood behind you and got a face full of oil:) It could be the gearbox atf when it hit the windscreen of dave's car, but when you were stood behind it still, was it definately the same oil? Was it just condensation or definately red oil? Quote Link to comment Share on other sites More sharing options...
Scooter Posted September 28, 2016 Share Posted September 28, 2016 If it's aft it must be flicking down the car's underside, no? So if the underside is as clean as a whistle then I'd be getting a cotton rag close to the tail pipe and reving and examining. If you are still getting a lot I might try and open up a decat pipe join and see if there is loads pooling up. Isn't there talk of needing a turbo oil feed restrictor on some setups. As it's running well does that suggest post engine leak ie turbo seal, tbh I've really no idea, I'm just mixing some common sense with things I've heard/read about.

wile e coyote Posted September 28, 2016 Share Posted September 28, 2016 When my atf got blown out of the breather it also got burnt off on the exhaust, as its that side, fare bit of smoke also Quote Link to comment Share on other sites More sharing options...
Dnk Posted September 28, 2016 Share Posted September 28, 2016 As Scooter says put a clean cloth preferably white at the back of the exhaust, even hold it inside the tailpipe and rev the engine then examine the cloth Quote Link to comment Share on other sites More sharing options...

Was it just condensation or definately red oil? I would say it was oil Tom! Got a good taste of it, and sure it was the good old Titan pro 10/30 weight:p. Do as mentioned and put a rag over the exhaust then will know for sure! Is strange as you don't seem to be smoking from the exhaust at all! The compression test seems fine! What's the oil level like? Have you been loosing any? Dave said his windscreen was covered in it, so must be chucking out a fare bit Quote Link to comment Share on other sites More sharing options...

Dave said his windscreen was covered in it, so must be chucking out a fare bit Haha sorry hahaha, I have done the test, and nothing came out at any point through the rev range, hmmm... The oil level is fine and have only been the expected amount to lose from any car over time... Not really sure now haha, I need to check the underside of the car for atf now...the thing I don't know is where is the breather on the gearbox?

Cheers Did you take the car out for a run and get it up to full temp before doing the test? Can't help on the where the breather is for the auto box I'm afraid Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted September 28, 2016 Share Posted September 28, 2016 the thing I don't know is where is the breather on the gearbox? Cheers Its right at the top of the box, near the bell housing, small plastic thing Quote Link to comment Share on other sites More sharing options...
