|
|
O.k, I finally got the engine going without blowing the seal on the oil filter, it drove ok without losing the oil for about 30 kay. Got home, parked it, left it over-night.
Started it this morning and oil absolutely poured out of the filter/breather on top of the rocker cover (my mate has one of those $5 filters on his rocker cover). It basically emptied the whole sump onto my driveway. I was using the right filter, and i tightened it up like a mother-bitch too.
One thing i never mentioned, the breather hose that comes off the sump on the drivers side, has been hooked up directly to the rocker cover. Can this cause enough pressure to build up in the sump and pressurize the oil enough to shoot it out ?
I'm going to look into the oil pump after the other posts advised the pressure releif or pressure regulator valve could be the culprit.
Can the oil pump assembly be removed without removing the engine as the Gregory's manual states ? After having a look, i think i may be able to get away with taking the radiator out for more room and remove the oil pump that way.
Or the other alternative is getting hold of a cheap good running engine and put that in for him. Can anyone please help out - this is extemely frustrating.

the hose from the sump isnt supposed to be hooked up to the breather on top of the tappet cover, why do u think it is called an "oil breather"??? |

hahahah fuck, thats all I can say! Hopefully you havnt cause enough crankcase pressure to fuck up ya rear main seal or even ya front seal.... (thats if they havnt blown out compleatly) |

So am i wrong in assuming that the crank-case pressure travels up through the timing case then into the rocker cover and is vented to either atmosphere or carb cleaner assembly via the PCV hose ??
On my car, the actual pipe fitting on which the hose runs from the sump is crimped and welded shut. No breather pipe exists from the sump itself, and yet i have never once had problems that would relate to this "mod" being the cause. No problems with oil surge/pressure what-so-ever in 3 years of owning (read : thrashing) the vehicle.
My actual concern for the pipe was opinions on whether the PCV pressure was great enough to recurcuilate back through the sump, or whether it shouldn't have enough pressure to surge back through it. I did mention there was a filter/breather on top of the rocker cover, i assume this would be the crank-cases pressure relif point. |

fuck knows man, your contradicting yourself here.. You just said there was oil pouring out of the rocker cover? Thats meens MASSIVE blow by which is cause from fucked rings or a hole in one of the pistons. The beather on the top of the rocker cover can only flow so much and if there is as much oil as you are saying in the top of the rocker cover then it wont breath much at all! Yes the pressure in the crankcase goes up the timing cover otherwise it wouldnt be commong out the rocker cover...

A compression test was one of the 1st things i did after he bought the car, all cylinders punched out just over 130psi each. That's why i was asking about the oil pump removal. Apologies for not reminding anyone in my post - it probably would have made advice easier to dispense by eliminating problem possibilities - my bad.
Laughing at other peoples engine woes isn't very constructive, put yourself in the position of someone else laughing at your problems instead of helping out, you'd lose a little respect for them and wouldn't take future advice from them very seriously. I'm sure if you had a problem i'd help where i could as that's what this particular forum is for.
It doesn't seem to blow any smoke and the compression test proved reasonable, so after advice from previous posts i read the Gregory's manual on the oil pump and it started off by saying removal of the engine was necesarry. More than anything i was chasing advice on whether i can avoid taking the engine out to service the pump. The breather line was more of a subject to gauge advice on whether it could pressurise the sump or not to bring on the symptoms of the engine lunching it's oil.
I know a little about certain areas, but not enough to know everything, so i was chasing constructive opinions.
I found the pressure relief valve people were referring to in the gregory's so i'm going to overhaul or replace the pump with a new item.
So, is there anyone on the forum that has had experience in the area of removing the pump without removing the engine ?
Constructive advice is more than welcome.

before you take the pump out see if you can get an oil pressure gauge
or if you cant take it to a mechanic and tell them you watnt too test the oil pressure compare wahat you get to the specs in the manual cos if pressures allright the n your motors fucked and it would be easier to get another secondhand one and drop it in .. maybeone of your oil gallerys is badly blocked? |

That breather hose on the sump you describe attaches to the small black canister (about the size of a dry cell battery) fixed to the front side of the bracket holding the fuel filter. It has three hoses running from it. Two facing the engine and one facing the radiator.
The top hose (facing the engine goes to under the air filter at the front driver side
The centre (front) hose to the fuel tank vapour tank
The lower hose, engine side, goes to the sump where your hose is connected to the valve cover.
Gemini's don't have a PCV valve. they use a different ventilation system which your engine seems to lack!
You are may be pumping oil through this line directly into the valve cover and it is spilling out the vented breather/filler when pressurised. You should not be using this vented filler/cover! It sounds like you also have a reasonable amount of piston blowby to pressurise the crankcase to that degree.
Best bet would be to return all the connections back to the way they were designed to be connected.
