Lots of white smoke


Recommended Posts

Think my Z is broken :(

 

When i changed the oil and filter there was 6 litres of oil in the car! replaced with correct amount but car is still producing lots of white smoke and is also misfiring.

 

Does this sound like turbo seals? there is also oil leaking out of the exhaust, somewhere in the middle underneath the car. and there looks like oil on one of the turbos when you look from underneath the car

 

Is there anyone in the london area that would be able to carry out the work for me?

the mis fire is probably due to too much oil in engine fouling up the electrodes. check to see if plugs are o.k. if dirty, clean (not with wire brush!)or replace them altogether. The smoke (sure it's white?) is probably just the residue left in the exhaust. this will burn off over time.

Too much oil and it can get past the seal between engine and gearbox (bit non-technical that description) and drip onto the exhausts. Blocked PCV valves can also cause this. I suggest you run it for a while with the correct oil, then have it cleaned underneath so that any subsequent oil leaks can be seen easily - then fix them (if they actually exist).

 

Good luck

Too much oil can cause hydraulicing (sp) in the engine, where the oil fills the bottom of the bores and when the piston comes down it tries to compress the oil, which tries to force the piston back up or stop the piston on its down stroke, result BANG! engine gone or terminal damage.

There seems to be a bit of a myth concerning this. On a multi-cylinder engine the volume of the crankcase is always the same, no matter if 1 of the pistons is going down because another would be going up ;) ;)

 

Now if we were talking about single cylinder engines, that really is a whole different ball game. :headvswal

not necessarily so, with the speed the engine rotates it causes surging of the oil, the engine rotates faster than the oil can be displaced
