Hi guys,

 

My zed is smoking, I have put a standard engine and turbos back in for this year and it did not smoke at all before the lump was pulled,

When I 1st start it there's no smoke then on idle it will start to smoke a little, but if I drive it theres no smoke...

But if I drive it hard on boost I get a puff of smoke, but if I drive it normal ish it does not smoke,

 

It had cats before and now I've removed them im thinking they masked the smoke,

Do you think it will mask it and stop it smoking for the summer if I refit cats,

 

If it will I only have one cat has anyone got a spare cat....

 

Any help appreciated,

Yeah sounds like you revealed a leaking turbo rear oil seal, you might be able to drive around with your aircon on and that stop it. Chances are if you refitted the cat it might work, you could do the one way valve trick to increase the negative pressure inside the block. (Bodge it trick the 200sx boys use)

Pain in the ass really.

Whats the 1 way block never heard of it, im pretty confident its the turbos, and it didn't smoke before at all, I have new pcv valves too...

Im kind of hoping I can get another cat weld them into my exhaust and hope it goes away lol...

Basically a one way valve in the breather tube from the rocker to acordion, search sxoc you will soon find it. Yeah re welding the cat in may help, but if it's goosed it's goosed.

Is it like a grey smoke, not white, blue or black.

Its blue/grey I have had turbos leak on another zed was the same has this,

If I rev to just over 3000rpm in neutral when hot I get a little smoke too...

Sounds like the tubs to me as well. Yes, I reckon bang some cats back in, that will increase the back pressure enough to stop the leak if its just the beginnings of seal failure. It may solve the problem long term, it did with my last car.

Cool I just need to find 1 bloody cat lol...I bet thats gonna be hard...

I might have some cats, let me look tonight and I will let you know.

Thank you, I really only need 1 cause I have 1, and only the cat part needs to be good because im going to cut that bit off and weld it into my exhaust...

Hi Terry...... you could try one of these in line. It may cure the smoking problem and also the LED would have the added use of under bonnet LED show lighting......... lol
