Samurai 20V Posted September 18, 2011 Share Posted September 18, 2011 (edited) Guys, I have been reading the threads on here about VSS and turbo seals and I am confused.. I was about to go ahead with a turbo swap with a 2nd hand set that I bought but the behaviour of the car is inconsistent. The car gives off a puff when started from cold, but clears up after that. Driving the car when cold,it is fine - no smoking at all.. When it heats up then it smokes when approaching a traffic light, basically when I realease the throttle. It then smokes a puff on take off.. At times continuously on idle, when I take off it clears up. On boost it seems to be clear, I cannot notice any smoke in the mirrors. However there are days when the car hardly smokes at all, this morning I could barely notice any trace of smoke.. (Usually the oil temp gauge reads over 100deg, today it was under 100deg, maybe an influencing factor?) I reckon it is turbo seals, but some of the posts on here are confusing me. Some ppl say valve stem seals cannot cause smoking so quickly, it only shows after the car has idled or parked for long time, others say turbo seals only show up on boost, not on idle. I rechecked the oil level, it is on the full mark, it was slightly overfull, I drained some out.. Help please, I cannot stand a smokey motor, I am almost ready to swap the turbos but I want to be sure before spending all that time and still ending up with a smokey motor. Thanks.

spiderpigcity Posted September 18, 2011 Share Posted September 18, 2011 it is defo over full. I blew a piston and hydrolocked my engine with oil from putting 0.5litres too much in by accident (it's a long story). On low boost you should be ok but on high boost you will defo bend a con rod or damage a piston. I have the badge to prove it. Better to run too low than too high IMO, within reason.

Thanks for the reply. However, the level is spot on full.. It was slightly over full but i drained some out and readjusted on level ground so it read on the full mark. The smoking on my car started after decatting the car.. Quote Link to comment Share on other sites More sharing options...
Guest neo9918 Posted September 18, 2011 Share Posted September 18, 2011 Your situation seems to the same as mine, my car is bpu and i get blue smoke when the car is hot, usually when i back off the accelerator towards a traffic light when coming to a stop. I get no smoke on start up. From what i can gather it the turbo seals allowing oil through. The fact you have decatted the car just makes the smoke obvious the problem was already there with the cats in. Anyway, i think its the turbo seals, the question is do you go for hybrids and put up with 400bhp, or go for the big power. Well thats at least the question im contemplating Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 18, 2011 Share Posted September 18, 2011 Sounds like turbo seals, but unless the engine is ultra low mileage I'd change the stem seals as well. Quote Link to comment Share on other sites More sharing options...

Got home today, car was hot, parked in front of my altezza with the headlights on, can see the smoke continuously on idle. Got the wife to drive the car, its smoking alot declerating and take off.. I have a set of turbos with 45000kms on them, going to fit them on..Single turbo comes later... I plan on doing the stem seals as well, car is doing 114000kms now.. Will look at fitting cams at the same time... Thanks for the help guys.. Quote Link to comment Share on other sites More sharing options...

spiderpigcity Posted September 18, 2011 Share Posted September 18, 2011 spray every nut and bolt and the twins side with lots of plus gas everyday for about a week, and get some spare knuckles. Quote Link to comment Share on other sites More sharing options...

spiderpigcity Posted September 19, 2011 Share Posted September 19, 2011 You will need a 12 and 14mm flex ratchet spanner to get at most stuff, i am doing one at moment. I have done a few and it's always a PITA. Quote Link to comment Share on other sites More sharing options...

spiderpigcity Posted September 19, 2011 Share Posted September 19, 2011 you won't get in without them, some smart arses on here will probably say you can but I've done a few and you wont get in with a ratchet and socket in a lot of places, especially around the exhaust manifold.

Hear you mate, will pick them up before I start, rather have more tools than less.. Quote Link to comment Share on other sites More sharing options...
