Hi all,

 

My 300ZX has a minor oil burning problem but I don't know from where!

 

If she is started, taken for a run straight away and isn't in stop/start traffic, there is no problem.

 

But if she is left on tickover from cold start, or is in slow stop/start traffic from start, inevitably I get an embarrassing plume of white smoke emitted from the exhaust! Seems to only be from one side too...

 

I've recently had the 2 filters in the front wings replaced, the PCVs were done about 7K miles go so it shouldn't be them, and I'm assuming the mechanics put the right oil in when it last had an oil and filter change (about 1500 miles ago).

 

Also it isn't smoking all the time which would indicate worn piston rings?

 

I am at a loss to know why oil is burning off and from where. Could it be worn turbo seals? If so, how much to replace?

 

Also another problem is that the clutch slips a little when I really floor it. I take it that the clutch is just worn and on its way out?

 

Appreciate any help!

sounds like rear turbo seals to me fella. £1500 to get sorted

Many thanks, keep me posted on the clutch, I'm sure I'll need a new one soon!

 

I might go with an uprated one if I can spare the extra cash. Found one for £240

If you was going to uprate your clutch id go for the exedy one tbh. Just my opinon and i think it works out around the same price have a look on ebay

No worries. I'll have a look.

 

Any ideas on the smoking problem...? :-(

Ive got the same problem as well ive got 2 pcv`s on the way and i replaced the turbos not long ago. Im off to zed world on friday so ill see what they reckon there

I'm pretty sure it's not my PCV's and I hope its not the turbos...!

 

Can you let me know what Zedworld think? Much appreciated!

 

As I said, I'm only getting smoke from nearside exhausts...rather confusing and concerning!

 

Good luck, hope you get it sorted.

If it's one side and white I think it will be the turbo... PCV failure smoke is blue

oddly i mainly get it from one side but my exhausts join down the centre section it is a hard one to diagnose as there is alot of people with smokey exhausts and alot of possible causes. Its just a case of eliminating each possible cause in turn. I do not know what state my engine was in before i bought apart from what i could tell when i bought it so im changing the parts that could do with a change after 110k miles.
