That breather is no longer there. The was badly maintained. Will have to look at compression next time.
I had a go cleaning out the big pipe which come from the fire trap, thats now clean but there was a lot of carbon **** inside the big end pipe. IS there another way other than compressed air to clean the plenum pipes out?
After compression check, that's my next clean out, OH and sort out the missing breather at the rear (the pic below).
and YEP! I am clucthing at straws... hitting the wall with time, money and patience with this one...
Cheers NAT
how does a pressurised crankcase from a blocked breather fill the valley with oil ?
I can understand it distorting the valley gasket but not how it gets a river of oil on it .
Grab a 2L bottle of coke .... Empty half of it ... With the half left in the bottle / Put the lid on, but not tight .... Now shake it up n downQuote:

Has anyone had a blocked breather system actually cause a river of oil in their valley . Im still having trouble getting my head around this . Distorted valley gasket yes but a river of oil ?
If the gasket is distorted it has probably broken the seal at the end. The valley cover can also develop holes on the crease when they buckle. As the hydraulic lifters and the crankshaft spray oil everywhere in the valley, any fumes pressure will cause the oily fog to squirt out of the gap. Basically its a job of fix the breather AND replace the valley cover and end seals.
Oh, and try running the engine with the oil filler cap off, see if it chuffs fumes like a steam train. It could have a broken compression ring or two. Or three.;) THIS will cause overloaded breathers, buckled valleys and rivers of oil quite easily.
Ok all,
Did a Comp test on all,
Passenger bank all 120-125.
Drivers side... front was 125,110,90,120 from front to back.
Cleaned out all breathers etc, all completely blocked. Also the one in the plenum chamber I took out welsh plub and tapped it a and put in a bolt for easy cleaning next time. Not going through sooo much oil now.
Also blocked off plenum inlet and just had the fire trap venting to air via the standard pipe. Did not seem to have anymore blowby then usual and did not smell like petrol or carbon etc. Just smelt like oil. Was not white either.
I'm going to compare it to my rangie tonight and get back to you all.

Thats nice nat p , but rather meaningless if you only did it dry . What were the wet readings ? . You did hold the Plenum butterfly wide open ,removed Flapper ,with all plugs removed didnt you ?
hay hay!
uhmm... no, time/equipment was an issue. I agree would have been really nice to do wet test as well. Short alot of equipment.. like oil and a means of getting in there.
About the butterfly etc etc no to all. Is this a Range rover thingy. Never got taught that at trade school, It was 20yrs ago so maybe I just forgot!!! hehehe
Bugger.
Well, maybe we are doing it again next week or so. I was thinking of doing a chemical check of the Rad water to decide if it is a head gasket prob.
AHHHHHHHhhhhhhhh...
This car is now ****ting me!!!
