Hi all
 
	 
 
	Firstly I'm fairly new here and this is my first post.  Bought first Z at the end of 2018, (2004 DE) had to do a bit more work that I had originally allowed for , including clutch and flywheel, new front end bushes, diff bushes, new coil overs, W Brace, a bit of rust treatment and undersealing, and new oils all round, filters etc.  Only thing I thought I hadnt done was replace the knocking fuel damper.
 
	 
 
	I was driving away and enjoying every minute.  Probably did about 1800 miles and recently noticed that the oil pressure was very low.  Checked oil level and it wasn't registering on the dip stick.  After adding 0.5 litre after 0.5 litres until I had added 2.5 litres it eventually registered on the dipstick.  So to rule out any dipstick issue I drained the oil and found that the engine had used approx 3 litres over 1800 miles.
 
	 
 
	Having looked at hundreds of threads here and on other sites, I have since carried out dry and wet compression tests, and a leak down test.  These are the results ( the dry and wet figures are on a hot engine:

	Whilst there is no oil smoke coming from the tail pipes I have noticed oil inside the exhaust pipe tips.  My question is, if the engine tests look ok, where is so much oil escaping from.  Finally I had a look at the PCV and it seemed to be ok with a good suck coming from the manifold - and the valve seems free enough.
 
	 
 
	Any thoughts or ideas would be very warmly received.  pic of plugs for info.
 
	Thanks
