No2

 

My Zed has 135,000km / 84,000m. Originally bought by me at 72,000km / 45,000m in Aug 99 and serviced by Nissan ever since.

April - C service.

May - Mongoose fitted.

June - Checked over by JeffTT, TB clean etc. Tickety-boo.

 

This August, she was left ticking over on a ramp while the bloke did the MOT. After a while, blue smoke started to drift out of both exhausts.

 

When I drove home there were a few clouds of blue smoke which cleared after 5 - 10 miles or so.

 

Today, I pick up the car from the bodyshop (where it has been standing for a few days) and again, blue smoke for a few miles before it gradually goes away.

 

Is this a) something that happens if you leave your Zed for a few days or b) a sign of old age with a nice cheap fix or c) a sign that you need new turbos?

 

More importantly, how can you tell?

 

Thanks, all

(wish I'd stayed on that bloody volcano)

 

------------------

That is a very tell tale sign of turbos on their way out im afraid.

Rule of thumb to tell if turbo is going is to leave car ideling for around 5 minutes plus and if you get blue smoke, it would suggest turbos are going tits up.

 

Thanks, Warren. Hmmmm thought it was. Bugger.

 

How to get this diagnosis definitive? If I leave it does it simply get worse and worse, go bang or do serious damage to other expensive engine bits?

 

Is that turbos or turbo oil seals on way out?

 

IIRC, expensive engine out job either way? Tsk, how tiresome.... (typed something else there before but decided to edit it out as I know how sensitive we all are to swearing )

 

 

Quite a number of cars smoke a bit when left to tickover for ages, mine has one or twice but it's not necessarily the end of the world - well not immedtially so anyway. Mine did this when I bought it 33,000 miles ago and it hasn't changed significantly, in fact it may have even got better.

OK so I had to go to Andy's site to find this before I remembered it was here all along (DOH!).

At the moment, it seems to go away the more the engine gets to full temp (so might not be rear seals). But then again, lasts for more than 30secs (so might be rear seals...).

 

Ah well, I shall give it a good blast tomorrow and see what happens (gulp).
