Smokin' Omega... HELP!!

[hugster62]

Hi Ian, you've hit the nail on the head, great explanation!  It is dripping from the bottom and i guess standing on the driveway i lose about a 5-6cm circle of oil deposited on the floor overnight. I presume it's dripping when drive also. I'm also pretty sure that it's not oil burning, it really smells like a hot car radiator. As for the noise, that's a new one, kind of like a knockin that you would get from tappits (that''s going back a few years) but louder and only under acceleration (about 55mph).

Mr Gaffney, I'm in peterborough, the guy who came out to see me charged me £30 and did nothing!! apart from telling me it would be £450 although he didn't know what the problem was??!!

thanks guys

this is tricky; no coolant loss & defo not burning oil so it must be fuel; a dodgy injector or leaking injector would cause it to smoke; on a diesel this would be white smoke but generally the smoke is constant. not sure what colour excessive petrol would be?

or it is burning oil and leaking it too.... 1 litre of oil per month is alot (to get from min - max on the dipstick is usually around 1 litre)...could be thin cheapo oil ( i assume it is if you're using a litre a month?) and as Mark said blocked breathers which is forcing the oil past the pistons and into the chamber?


have you cleaned the breathers? i would do all the cheap/free stuff first so that we can knock them off the list.

sure, can anyone point me in the right direction of how to clean the breathers (sorry i have no manuals or anything with this car) and i will gladly go and do that if it will help eliminate another possibilty.

look in the maintenance guides section; im not sure where you would find them on this engine (i still dont know where mine are) but i would look under the ecotec plastic thing.

hopefully someone can point you in the right direction ifyou cant find anything in the guides section.

If the tappits are getting loud the oil pressure is dropping in the engine.

I needed a new oil pump and my tappits sounded like a tank engine as there was no pressure in the oil system at all.

I was told that a seal can go and it leaks oil all over and the pressure drops i think its a pressure release valve

I could pop down next weekend, help you clean the breathers do a compression test and give you my 10 pence.  I have quite a bit of experience on HG blows so I could tell you there and then if it is that.

Unfortunately I cannot do anything before then because of an exercise.......

Personally, and just to confuse you further, I am thinking blocked injector/faulty spark plug with a water pump on the way out...

If it was HG then the smoke would be constant from the first occurance not intermittent like you say - unless the blow was magically resealing itself every now and then.

try this one. Although its for a 2.2 it will be similar enough (I used it on my 2.0 - improved things no end)

BTW - tip - update your profile to show your location and car, esp engine.  Will help people help you without having to hop around the thread.

Cheers
Ian
