RobEvans Posted August 6, 2007 Share Posted August 6, 2007 I fist noticed on sat night when i put my car in reverse it was kicking out a puff of blue/Grey smoke. But come today its doing it when lightly reving the engine, quite alot of it too, also i notice some small grains of sand type stuff also. The engine was warm to (30 mile drive) I changed the auto box fluid lastweek and maybe put alittle to much in... I doubt thats the cause though... The car seems to drive ok but I dont realy want to give it death. This couldnt have come at a worse time as Im now not working and in serious debt:( So give me the bad news please...

Nic Posted August 6, 2007 Share Posted August 6, 2007 Rob, is it definitely coming out of the exhaust? Just wondering if you have a leak that is dripping on the exhaust and is then being burnt. Quote Link to comment Share on other sites More sharing options...

Marty Posted August 6, 2007 Share Posted August 6, 2007 i may be wrong, im known to be quite often Put your cats back on mate, it'll increase the backpressure and your turbo seals will stop leaking... as much. I took my cats off mine, and it was like a smoke machine, i put them back on, and it was fine, i did another 12,000miles before changing the turbos Quote Link to comment Share on other sites More sharing options...
RobEvans Posted August 6, 2007 Author Share Posted August 6, 2007 So are the turbos shagged??? Quote Link to comment Share on other sites More sharing options...

edge Posted August 6, 2007 Share Posted August 6, 2007 Does it happen on idle? Quote Link to comment Share on other sites More sharing options...
Nic Posted August 6, 2007 Share Posted August 6, 2007 If it IS the turbo seals, they will still work fine, it just means embarrassing blue smoke out of the tail pipe. You're not far from Chris Wilson, I'd suggest paying him a visit so he can identify the reason for the blue smoke. Quote Link to comment Share on other sites More sharing options...

RobEvans Posted August 6, 2007 Author Share Posted August 6, 2007 OK... its ok on idle but just a small rev to 2k and the blue smokes pluming out, seems to boost OK. If I buy Envys hybrids for £1300 will this defiantly eliminate the problem? I cant afford to waste money at the moment Quote Link to comment Share on other sites More sharing options...
RedM Posted August 6, 2007 Share Posted August 6, 2007 I wouldn't go for hybrids myself. Why not find some low mileage stockers from one of the seemingly infinite single conversions. Quote Link to comment Share on other sites More sharing options...
RobEvans Posted August 6, 2007 Author Share Posted August 6, 2007 Would replacement turbos sort the problem though mate??? I dont want to fork out twice Quote Link to comment Share on other sites More sharing options...

RobEvans Posted August 6, 2007 Author Share Posted August 6, 2007 So whats best for me cost and reliability wise? I dont really fancy buying 2nd hand turbos. Hybrids or a really small single??? I dont really want over 400bhp Quote Link to comment Share on other sites More sharing options...
Marty Posted August 6, 2007 Share Posted August 6, 2007 Your impatient The 'best and cheapest' option would be to put your cat back in, if it is the turbo seals, it should stop the smoking, aslong as the seals aren't too far gone. Either that, or buy some 2nd hand turbos, but taking yours off and replacing them is a PITA, so id only do that when yours are smoking with the cat in too Quote Link to comment Share on other sites More sharing options...
RobEvans Posted August 6, 2007 Author Share Posted August 6, 2007 Id rather get it sorted soon as mate or it'll just annoy me... It makes more smoke than a ford transit thats done over 200k! Theres grit coming out to... Thinking of a very small single Quote Link to comment Share on other sites More sharing options...
Marty Posted August 6, 2007 Share Posted August 6, 2007 i cant see where the grit would be from Your looking at a fair few thou for a small single, to do it properly mate. As you'd really want better injectors, cooling, ecu, etc, soon adds up. Buy a 2nd hand pair of turbos, and get them re-sealed etc, then fitted. That'd be your cheapest option.

RobEvans Posted August 6, 2007 Author Share Posted August 6, 2007 ok thanks for the imput guys. I'll ring around tomorrow Quote Link to comment Share on other sites More sharing options...
Sheefa Posted August 6, 2007 Share Posted August 6, 2007 Hi Rob, Search for any of the threads I started back in Feb, March, April, May, June!!! etc with the word 'smoke' in it mate and you'll come across a lot of info! I ran hybrids in mine, but the oil seals on those went due to prior owner misuse. I'd go for a set of hybrids personally, unless you're happy with some J-specs but again they could go 'soon' especially high milers. Then again, they're a cheap alternative. Envy Hybrids are around £1100 iirc. Deffo sounds like Turbo seals but I would imagine only tubbie no1. Does it smoke when ABOVE 4k rpm?

Nic Posted August 6, 2007 Share Posted August 6, 2007 So whats best for me cost and reliability wise? I dont really fancy buying 2nd hand turbos. Hybrids or a really small single??? I dont really want over 400bhp Rob unless you have the funds to do a proper job of a single conversion, I would either stick with a pair of new/used J-spec turbos or hybrid turbos from a reputable source.

Chris Wilson Posted August 6, 2007 Share Posted August 6, 2007 The only thing I can think of to explain "sand or grit" coming out of the tailpipe, and the newly acquired smoke is the ceramic turbine wheel on one of the turbos breaking up. I may be wrong, but when the wheels break up the residue is black gritty and a bit like big grains of sand. The imbalance will cause the seals to leak, and smoke will result. I have never seen this on a MKIV, but have seen it on at least two Skyline engines. Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted August 7, 2007 Share Posted August 7, 2007 I wouldn't go for hybrids myself. why not?? The only thing I can think of to explain "sand or grit" coming out of the tailpipe, and the newly acquired smoke is the ceramic turbine wheel on one of the turbos breaking up. Think he is in a UK spec Chris Personally mate I would go for a set of hybrids in your situation...whats your current spec? A true 400 at the wheels is fairly hard to acheive on stock turbos Quote Link to comment Share on other sites More sharing options...
