04 jetta 1.8 was driven with the oil light on started blowing smoke now the cylinders are filled with oil what could it be

Did you remember to reconnect your Cam Position Sensor after putting it all back together? One tooth off shouldn't have bent a valve (but pressure checking cylinder will answer that). Did you check TDC once the belt is tight?

Oil light at idle indicates engine wear. New oil pump may not help if pressure is dissapated by worn bearings in journals and other moving parts. Blow by indicates worn rings "Puffing" possibly a cracked ring. Sounds like this engine has been driven hard or maybe abused. Not enough oil changes? Possibly need a rebuild to restore power and performance. I would do a cylinder pressure test first, see if compresion is any good. Will show any one cylinder problem also. If money is an issue - it starts and runs, just drive it till it stops..? Sorry to bring bad news. The oil light should have warned you before the purchase.

is there any coolant in the oil or oil in the coolant. It sounds like a head or gasket problem. Cooling system & oil system are supposed to be sealed systems. If u have add fluids it must be going somewhere. Leaking, burning etc. Good luck, get it checked out.

You need to erase the code for it to start,If it still wont start chech the timming marks again with cylinder #1.,you might have top dead centered cylinder #4 by mistake, when you did the belt.
erasing the code first might work because a code 1582 could have more or less filled up the sensor banks when the belt broke ,causing the computer to shut down everything.
If after you erase the code you get the same code then you have to re-align the timing markg because the position causes the computer to overload trying to correct the mecanical problem it has to deal with because of a miss alignment of the valve train.
Good luck,Gary

blue smoke indicates rings/bores are worn,time for a rebore.....

this sounds like the cam belt may have broken if the engine wont run at all, if it still runs then im thinking its a head gasket blowen or an inlet valve is not seating right (ie: bent or badly pitted) and its venting the inlet manifold so your seeing a puff of partly undurnt fule or smoke! check with a compreshion tester all the cylinders they should have at least 150,,180 psi if very low then tip in a small drop of engine oil and retest,, if one or more cylinders are still low (ie: both next to each other) its a head gasket blown also look behind the frount cam belt cover to check if the cam shaft is turning around if its not the belt has broken,, and you may well need a recon cylinder head as it would have bent some of the valves in the head,,,,normaly if the cam drive belt has broken the motor just locks up, but if it did not lock up it will spin over very fast and would not even try to fire up,, its about 5 to 8 hours work changing the head gasket and fitting a "new cam belt",,

It is hard starting my VW 2003 Jetta. It usually take 5 to 10 cranking before it turns over. Then it run normally. It only happens when the car has not been driven for about 6 hours.

valve seals are going. when car sits excess oil gets past the valve seals then when you staRT up it burns the oil off then runs fine and no more blue smoke. It is fine to run like that had the same in a dodge caravan 1996 6cyl. ran another 100 000 km. and still ran fine got rid of it for other reasons.

When was the last valve adjustment?
An old timing belt and T-belt guide will offset the timing.
Can a shop do a compression test on the engine?
Do a motor flush before the next oil change to free up the rings and clean out the head.
This is the inexpensive method to restore compression.

If it's the org. engine it will has over 80,000 miles on it.
It's normal to has the valve stem seal/oil seal on the head to leak oil into the cyclinder.
The smoke you see is the motor oil drop from the seals.
It land on the top of the cyclinders and it create black smoke at start up.

The inexpensive fix is to start using high mileage oil with seal conditioner.
This will help soften the rubber seals and help reduce internal oil leak.

The correct fix is to wait until it's time for a head gasket replacement and let the professional service the head.
Complete head service is the only method to stop this internal oil drip problem.

Hi,

Sounds typical of head gasket failure.

With this you get oil into cylinders / water into cylinders, burning oil, loosing water - but no leaks. "boiling" of radiator and overflows.

Check your coolant and oil levels - they will be low.

Get a few quotes for a head gasket replacement - and timing belt change, as it has to come off when you do this anyway & no sense putting an old one on - they often snap if retensioned.

If this solves your problem, please take a moment to rate as Fixya! thanks.
