need heavy advice freaking new problem
 

i need suggestion as what to test for 100% accuracy. my 02 x5 3.0i has been showing white smoke at start up and a tad running rough when it sits for a long time or over night.then after a few minutes it clears away and runs smooth.and ses on with misfire on cyl 1,2,3 even though it has 6 new coils and plugs i took the ccv out today cuz i order a new one after reading of them failing well there is nothing wrong with it after i took it apart.i took the plugs out=cyl 1,2,3 to check compression. well while cranking it over a substance that looks like antifreeze keeps spitting out of cyl-3.but the car temp is always steady in the middle after warm up i've been stuck in heavy traffic for hours and no sign of over heating at all.how can i check if possible start of head gasket.the old plugs show no hint or sign of antifreeze.

your positive its anti freeze and not oil fouling the plugs. sometimes if the valve cover gasket leaks it gets into the plugs.

it seems more watery than oil residue.will check better in morning as it was late when i discover it this evening.

There's a kit that you can buy that attaches to the radiator. The kit checks for combustion gases in the radiator which will indicate a blown head gasket.

Here's a link to the product. There are similar products on the market.

You can also drain the oil and see if there is water in the sump pan.

does is smell like burnt oil from the exhaust or more of a sweet smell?

the 2 times i notice it smell like antifreeze BUT not strong smell.if that makes any sense

white smoke - water vapors... or, as you may have already discovered, antifreeze... I do not know how to resolve the issue nor how to further test it (involves "juicy" parts of the car!!) but I know for a fact that white smoke is not good... some stuppid gasket somewhere inside the engine went kaput and collant is leaking inside the engine...

at this point the leak is small but over time it will grow bigger and it will blow your engine... you need to do something, and do it rather sooner than later (sorry, I am helpless in this kind of situation!!!)

Seems like your wife got taken with this beat up BM Trouble U. Now we know why the SES light was taped over. Sounds like a blown head gasket, a very expensive repair, probably going to cost almost as much as what you paid for the BM Trouble U.

Kinda sad but true, or even worse a warp block from letting the engine overhead.
Best of luck to you and your SAV.

well the strange thing is from sitting all night the radiator still held pressure meaning from when we drove home. when i went to take the reservoir cap off i heard air coming out from holding pressure. i crank the engine over with cap off no bubbles in reservoir. put cap back on.crank engine again no more fluid coming out of cyl-3 so when it built pressure is the issue.
