over the last few days i have noticed my ce est 1275 metro sport engine is blowing oil out of the dipstick hole and alot of pressure seems to be blowing out of the oil filler cap/if i look inside the rocker cover the oil laying inside seems be be bubbling from head any idea

i changed the head gasket today but no difference

[TimS]

check all you breathers, chances are that ur oil cap or crank case breather is blocked

[Pavel]

This is not good! Could be piston rings to be honest. Does the car burn any oil?

[ukjay]

the breather in the cap is almost like steaming out of the holes and i have checked both of the breathers(i have blown down them) and both are ok and i have taken them of the carb and put those lil filters on them. i dont really know if it burns oil it is losing to much from the blowing out to tell.

[Jammy]

Stick a spring on the end of the dipstick with the other end somewhere on the engine, mines hooked on the distributor clamp thing. This should stop you loosing too much oil. The most common way of telling whether you are burning oil though is to see whether there is a bluey white smoke coming out your exhaust when the engine is running.

dont the replacement dipsticks have a rubber seal ?

[Guess-Works.com]

Is the oil been thrown out the dipstick at idle... and have you done a compression test...

The only thing which can cause that amout of crankcase pressure is a blown piston or ring.

[dklawson]

I agree with GuessWorks. Do a compression test. Also, if you can borrow one (or want to make one) do a "leak-down-test". Google for leak-down-tester and read up on them. Basically using this tool combined with an air compressor and good ears will allow you to determine if you have a problem and whether it's the rings, valves, or head gasket.

With the amount of pressure you're describing, I'm inclined to say you have broken rings.

[Turbo Nick]

yup i'd also say broken rings/ melted pistons.
mine did exactly the same when i blew 3&4 to pieces, wasn't too bad at idle but as soon as i hit boost it threw the oil out of any hole it could!


*edit* i've got an MG engine for sale if you want it...lol :wink:

Bud666... is the person in your picture/avatar "Bob Ross"? The man in your picture looks just like a guy who had a DIY art/painting show over here. He was very entertaining. Unfortunately he passed away a few years ago from cancer.

[Turbo Nick]

yes! the dude was a legend! with the titanium white and the 3/4" fan brush and the painting with a knife.....lol

[dklawson]

Don't forget "a little burnt umber" and "some little branches just poking out over here". He had a voice that could lul anyone to sleep. I miss his shows.

[Turbo Nick]

hehe

cant forget the yellow ocre either! and beating the devil out of it. the little interludes with all the animals he'd fostered were wicked. We spent many a stoned night watchin the joy of painting!

[ukjay]

no it is not burning any oil exhaust all clear

putting a spring on the dipstick wont really help will it

bud666 that sounds exactly what mine is doing

bought another 1275 sport engine at the scrappy today and fitting it saturday (£100)
