Question

Just bought a W Reg Astra that was a stolen/recovered car from breakers,it was probaly thrashed to death, is this exspensive to fix,the oil looks fine with no trace of water contamination from failing head gasket,the engine purrs like a cat!anybody any ideas ,with prices to fix,cheers

Answer 1

sounds like the oil control rings to me .

Answer 2

If its white smoke then it is obviosly heating water from somewere . just because there is no contaminate in the oil does not necerserily mean the head gasket has not blown , if there is a break between the water jacket and the cylinder . water will not get into the sump but will feed direct into the cylinder causing white smoke , try puting a temperary solution to see if it cures the proplem for a while , buy some K SEAL perminent coolent leak
if that cures the proplem then you know what to do. PS there is not such animal as a perminent cure for a blown head gasket , but it will work for a while

Answer 3

White smoke means your car is burning water or antifreeze. Check your engine oil to see if its contaminated with antifreeze. Dip it or check the oil filler cap. If it looks like a chocolate milkshake colour then there is antifreeze in your engine oil. If this is the problem don't start your car again...it could cause serious problems. There may be a problem with your head gasket. This can prove expensive.

Blue smoke means your car is burning oil. This is common in older cars with high mileage. If its burning oil...the oil has got into the cylinder through a dodgy seal, gasket or O-ring and will need replaced.

If your car is also mis-firing too much oil has got into the cylinder and the spark plug will need cleaned or replaced. Not really expensive to clean or replace.

Hope this helps you!

first of all, Jewish is an ethno-theological history; that's the two a ethnical inhabitants and a faith. that's complicated by applying quite a few aspects which incorporates that Orthodox Jews and Zionists do no longer settle for converts to be actual Jews, yet present day Jews do. it is likewise possibly that the classic Hebrew human beings have been created from a distinctive inhabitants of nomads that already had a distinctive ethnic history. 2d, so some distance as "race" is desperate. the main recent theories on race point out that there is not any diverse "Caucasian" race and that they are quite a hybrid of the ******* and Mongol races.

Answer 5

Hi there i would start off with a compression test and see what you get the readings should be roughly the same then i would get a garage to perform a cylinder leakage test. This is where compressed air is forced in to the cylinder to simulate compression and you can then tell where the engine is leaking

Answer 7

I would guess it needs valve guide seals. Sounds like oil is leaking past the seals and getting into the cylinders.

Answer 8

its burning oil, it will be the valve stem oil seals very common on astras could be the rings also but do valve oil seals first cheap to do

Answer 9

oil is your answer. does it smoke when you first crank it and if it is does it quit smoking after it has ran a few seconds. ifso your valve seals are worn in the engine

Answer 10

You mean it's sucking in smoke? Never heard of that ...

On the other hand, if you mean EMITS, then you have a knackered car.
