hi there,

This is my mom 06 civc automatic, I noticed that blue some came out from exhaust when cold start, and I decided to change the valve cover and 4 new sparks. Unfortunately, the blue smoke till come out from the exhaust after cold start, and its out even more dense while drivin on highway. Any suggestions for that issue?? Thank you very much!!!!!!!!!!!!!!

 

it's burning oil. new plugs and valve cover will do nothing to fix that. do compression and leakdown tests.

 

^^ This

Is it losing power yet? How much oil is left? Usually it's oil getting past the rings but, could be other things. The leakdown should tell you where the loss of compression is.

 

Thank for the helps, and leakdown is only done by mechanic, right??

 

you can do both yourself with the right tools. you can rent compression and leakdown testers from most parts stores but you'll need an air compressor for the leakdown test.

 

cool, tks dude :D

 

uh oh sounds like someone has some bad rings and/or valve stem seals or burnt up valves...

 

Really good video of a leakdown test:
