what does it mean when u take the dip stick out and u here shhhh. pcv valve is rattling so i think its good.

Just sucking in air there as well as from the air inlet hoses.
Put your finger over the end it should suck in.. If it is blowing out there is a pressure buildup either worn engine and heaps of blow by or the pcv is faulty maybe. Vee

i'll try that finger thing, it did sound like it was blowing but hopefully not. it's a tw with only 160000 on the clock so shouldnt be to worn but in saying that it was poorly maintained looking at the crap inside the top end.

Engine running or switched off

here he is . about 15 sec after i switch it off. thats when i always check my levels.

Off topic, but years ago, my friend had (still has) a Fiat 500 Bambino. He came home from work for lunch and noted a pool of oil under the car. Opens rear hatch and see the dipstick laying on the engine cover. Puts it back in, starts the engine and PFFT - the dipstick gets spat out again. He looked at it and saw that the leaf spring on the dipstick blade had broken and the end of the blade was bent over, so he went in and ordered a new one.

He looked at the workshop manual and there was a section titled " Spitting the dipstick" or words to that effect. The book says that possible causes are a buggered poofer valve or a worn engine. At this stage, he called me in. We checked the poofer valve (crankcase ventilation valve) and it was working fine. So we pulled the engine out (about 1 hour's work) and stripped it. Everything was fine - the ring gaps were within original tolerances, no obvious gasket leaks, no cracks anywhere. Reassemble engine and put the disptick back in, start the engine - PFFT!

Finally, he got a new dipstick and he put it in and no more PFFT. All it was was the leaf spring on the dipstick blade. The engine is a 2 cylinder and both pistons go up and down together, thus compressing the air in the crankcase. The poofer valve lets that air out and then keeps the crankcase at or below atmospheric pressure. The leaf spring was required to stop the dipstick from being pushed out as the pistons went down. So simple, yet so complicated... Magnificent little car that 500 is.

yer the only thing that holds these ones in is a couple of o rings. this is my third magna and the dipstick is held in tighter than any one ive had.

I would say breathers are blocked

Spot on mal. The pipe with the pcv valve was all clear but the other 2 i couldnt even blow threw, I have a feeling u just saved me some blown seals or maybe even an engine. cheers.

Now you have to ask yourself the question "What was the cause of the blockage?" "What is the rest of the engine like?" It sounds as if the car has had severe lack of maintenance in its lifetime. Oil flush for a start?

Its already had a flush but im doing the lash adjusters soon and when i do the top end will get a good scrub followed by pan off and pickup cleaned then another flush and that will do it 4 me.
