Smoking

[Adam B]

Hi all,

I own a 2005 350z @ 95000miles

 

Fitted a manifold back exhaust and ever since I get a large puff of blue smoke (oil) when blipping throttle in neutral or when pulling away from a junction after coasting to a stop.

Doesnt happen all the time though.

I am leaning toward breather system but wanted to check if anyones had similar issues.

Thanks

Is it now a decat system?

 

The Cats may have been helping stop the smoke.

very well could of been, yes now a straight through.

You have answered your own question.

Lol, not quite what I meant. What causes this sudden puff?.

Is there a way to eliminate it?.

Is it wise to upgrade the OEM breather system to cope.

Or, in all likelyhood my rings are shot and I`m doomed?

Sorry should of worded it that way first time.

It's part of the maintenance on z engines that you change the breather value off the top of my head its 74000 service that it gets done .Make sure you keep an eye on the oil level .

When you removed the oem cats you also created a passage for the oil to exit.

 

You did not see it before because the oem cats burnt it up.

 

At 95k I suspect that you will be using a bit of oil

 

However you will be using the same amount of oil as before and if that was not excessive then all will be good.

Thanks, 12hr nights so my thinking cap wasn`t on. Was a little paranoid as blue smoke is never a good sign.

Cheers
