kv6 blowing oil out of dipstick hole-BAD

brook shaw · 11th February 2013, 13:39

my zt 190 is blowing dipstick out ,,and the oil coming up it is on torrent levels..
virtually empties the sump!!

open the oil filler cap on idle,,and it lets go a massive "hiss"

breather tubes all intact

any ideas...?

was running,and still runs fine
127000 miles full history
no smoke,or rattles
doesnt burn oil between changes

this problem has only just started never done it before,,

anybody help?

seems like crankcase pressurisation to me>>>

The breather tubes could be blocked. I tried repairing my breather t piece with a replacement and due to the hole being too small, caused a huge build up of pressure like what you're describing.

Agreed, you have a breather from the front and rear banks, they join together just at the back of the alternator and then the pipe goes across the top of the engine into the throttle assy, they are blocked somewhere along the line

This is the pipe they are referring to:

If you are getting pressure release out of your Oil Filler Cap, this will be blocked.

Thats the breather pipe i am after tried changing the t piece and snapped the front pipe

The pipes become extremely brittle so very easy to do. I tried and gave up and bought a new one from Rimmer's.... http://www.rimmerbros.co.uk/Item--i-LLH102660

When I bought mine I found that the Land Rover part was about £5 cheaper, not anymore - it's now £3 more!

been off line for a few days

combination of the 2 front breather pips being blocked with mayo and carbon and the gauze filter blocked with carbon in the rocker cover

seems perfect now,,even goes a lot better too !!

See, where would you be without the forum!? I'm glad it's sorted for you. The breather filters are on my list of to do jobs as it is anyway as they apparantly can leave to the manifold rattle if they're too gunked up with oil.

Enjoy the v6.
