well, today i decided to change the oil.... i need someone to help me understand how the following could happen. Drained the old oil out (black - it definately needed replacing), replaced the filter (filled new filter with oil before i installed it), then put 9 quarts of mobile 1 0w40, made sure it was at the full mark), started it up and ran fine for about 5 minutes, then it started smoking alot. pulled the dipstick out to check it again, and there i saw foamy WHITE WHITE WHITE. how in the heck would an oil change do that? right away i think headgasket, but is there another route that oil and coolent can mix?

if it is the headgasket, it must be an internal break, cause it's not dripping down the the floor.

btw, anyone know cheapest place to buy new headgaskets?

thanks in advance....

Was it overfull ? The white sludge could be from condensation.

juvius

it was right on the full mark. to me the sign says head gasket, what steps should i take to find out what it actually is?

thank you

What colour is the exhaust smoke?

Is there any evidence of the previous 'black' oil in the anti-freeze?

juvius

The exaust smoke it white. no evidence that i've seen, what should i look for?

thanks

Oil and coolant make a light brown milkshake. Was the smoke from tailpipe or from the engine bay ?

Giovanni

I thought the oil capacity was 7.5 litres?

I think 9 quarts plus a filter full is too much, no?

juvius

it was 9 quarts including the filter fill....

thanks

juvius

the smoke was both from the tail pip and under the hood.....

thanks

You beat me to it by a second, Gio!

Also Juvius, check to make sure the bottom of the dipstick handle isn't broken and able to slide along the metal shaft. Mine cracked right above the o-ring gasket on the handle, then slipped down the measuring shaft when I pulled it out. I didn't notice this, and when I reinserted it into the tube, the lower position of the broken piece prevented the dipstick from seating all the way in, so the measurement was reading lower than it actually was.

I hope that make sense to you. A pic is worth a thousand words, but the car is off in storage, so that aint gonna happen. Sorry.

Steve...........where is the smoke coming from under the hood?............is it indeed smoke or steam? does it smell sweet?

chaadster

Anyway, 9 quarts is too much, by a quart or so. Drain some out.

ZEUS+

How long did you run it for ? Is the smoke thick ? Has coolant level gone down ? What is the temp. out there ? Sorry about all the questions.

juvius

makes sense.... that may be the problem. does it hold 9 quarts or 7.5 like earlier stated?
if i overfilled, would that cause this problem? and is there a way certain way to take car of it, or would i simply have to drain the coolant and replace and the oil and replace to correct level?
