Verify plug was not loose and try to reinstall when engine cold. Look at plug for electrode damage/melt/discoloration.
Most logical cause is a loose plug
Had car been running funny or hot prior to "blow out"?
The car would blow a head gasket before it blew a plug unless previously the plug was cross threaded and severe damage to threads in aluminum head weakened plug holding.
Typically a good cylinder can compress 130psi

At your local parts store ask them to supply you with the proper heli-coil kit so you can put new threads in it. generally cost around 25.00 bucks

Accidently drove a little ways with out much antfreeze/coolant...and i think the water pump is out... and now wont start... aside from waterpump, what should i look at?


OUCH! ok so the coolant is the only thing keeping your engine from overheating and warping. Usually the engine light can be decoded from your local auto parts store, sometimes for free (in hopes you will buy the parts to fix the problem from them). That may tell you if something else is preventing the engine from running.
Basically you have 2 big things to check, make sure you have spark, make sure you have fuel. Take a spare sparkplug unplug one of your plugs and plug the spare on. Lay the loose spark plug somewhere on the block touching metal. Have a friend turn over the engine a couple turns and look for the spark on the plug. Don't touch the spark with your fingers when rolling the engine, that's very high volts. if you see spark that's good, plug the wire back on it's original plug. Fuel is a little harder, but a quick shot of ether (usually called starting fluid) in the intake can tell you if the fuel is the problem.
Water pumps are usually driven off the same chain/belt as the timing. I'd have them replace the timing belt at the same time to save you some bucks in the future.

Changed O2 sensors and white smoke starts pouring out of exhaust


White smoke is usually steam which would indicate a blown head gasket or crack in block. Hope it's something easier.

I BLEW THE HEAD GASKET WATER IN MY FIRST CYLINDER.


Your only fix is a new head gasket

I have no idea why you would have done
anything else but take it apart, to diagnose
what was need to resolve

Now you have all sorts of sealer in there, that
may come back to bite you some day

I own a 2002 Kia Rio RXV and my husband decided to change my spark plugs. When he pulled them out of the engine, they were all covered in oil. What would cause this and is it worth fixing?


You have a 4 cylinder and there are seals in the cover around the spark plug holes. You can replace these with a rocker arm cover gasket set. Costs about $25.00. The oil does not hurt the sparkplug, but over time it will affect the plug wires/ boots and cause a misfire. these are not hard to replace. Your call.

Can oil in spark plug hole after changing coil packs,plugs and wires cause 1999 Sportage to run worse than before? Engine is "dieseling" and blew white smoke for a minute or two. Changed valve...


The oil down the plug hole will cause the white smoke, and as you said it cleared in a couple of minutes, but also may have oil fowled the new plug. It cannot have damaged the engine.
pull the oily plug out and clean it in some solvent and try again, make sure the plug caps dont have oil on them

could be a manifold or a blown head gasket , you need to get this problem fixed ASAP or it could be a cracked block best to let a mecanic check it out and be sure what it is

Dumps raw gas into engine


Just a few things to check. Take off the fuel filter and make sure there is no water in it. If you have put in different spark plugs than AC Delco, then change them to AC Delco. If you haven't looked at the plugs or the fuel filter, then it is way past time to replace the filter and new AC Delco spark plugs only. These places that insist that you use Bosch plugs or split fire plugs don't know ****. The Delco plugs are made especially for your engine and will out last those cheap non-working Bosch plugs.
If the fuel filter and plugs don't fix it, make sure your air filter intake isn't stopped up with a bird's nest. Happens a lot. If it still misses after new plugs, you may have a fuel injector sticking.
The bad smoke is the gas-thinned oil passing the rings and unburnt fuel smoke. The missing really bad is most likely fuel soaked spark plugs. Make sure you change the oil while changing the plugs or you will have a redo. Let us know if any of this helps. Dale
