Question about 2003 Kia Sedona
We started noticing oil under the van about 3 weeks ago. Found out the cam shaft plug had popped out.
Replaced that and the pcv valve. Did a complete oil change and replaced the oil filter.
The plug continues to keep blowing out and we are still losing oil.
Finally took the van to the service depatment and they ran a diagnostic. The report said the engine is blown and needs to be replaced.
Is there anything else that can be done?
I just don't see the need to replace the engine when it runs fine with no other problems.
Did ya wash it right before this happened? If so the Computer is wet and/or the connector(s) to the computer are wet or moist.. Even if ya didnt wash it.. Locate the puter and investigate it.. it only takes a drop of moisture to ruin the continuity of the computer. As per Code 1631 indicates with us. To an average person with an OBD2 Scanner.. 1631 would mean the puter is fried.. but wha Ive seen is just wet/moist connections at the ECM (computer itself).. Hope this helps.. thank you

this vehicle has coil packs for the ignition correct? have you ran the engine at night with all surrounding lights outs so its really dark. spray a mist of water on the coil packs and spark plug wires to see if you have spark/voltage leaks jumping out from them. sometimes the tiny sparks will be so fine and skinny you can barely see them so it needs to be dark. hope this helps your trouble shooting. a coil pack could have such a fine crack for the voltage to leak from that you cant see it.

you need to have a scan done to see what is the exact problem.
is it egr evap electric etc.gas cap? the check engine generates a code that tells what system is defective.
