So I recently cleared all of my engine codes, now I have a new problem...blue smoke from the exhaust. Help.

 

Burning oil my friend!

 

Word, but how do I make it not do that? If there's a link to a thread, or if its a fairly simple fix.

 

When does it smoke? Cold start? When it's warm? High rpms? Oil on the plug wires?

need more info so we can help

 

Blue smoke on acceleration, not sure if any other time. Also throwing code 43 (Fuel supply system)

 

I thought you cleared all the codes?

 

I did, however, on my way to work this morning the engine light came back on. Code 43.

 

So you just reset the ecu? Didn't fix the actual problem? Or is this a new issue?

 

It was originally throwing codes 10&14. IAC and IAT. Cleaned IAC, replaced IAT, reset ECU. It ran fine with no light for about 3 days. Yesterday my buddy and I were driving and he said I have blue smoke coming out whenever I am on the gas. Today the CEL came back on.

 

Bad rings, you aren't going to be fixing that without a rebuild. Code 43 could be a lot of things, but is most commonly caused by an O2 sensor that's going bad, but isn't bad enough yet to throw an O2 sensor code.

 

Re-build parts list?

 

Do a compression test first and if any cylinders don't hold compression. If one cylinder doesn't hold compression it has bad rings

 

"Blue smoke" or "black smoke"? Makes a difference. Rings will usually blow smoke even at idle. Now if your dumping fuel you would see black smoke... are you low on oil, or constantly have to add oil?

 

I just did an oil change on Sunday. Between changes I had to add 1-2 quarts. Def not black smoke, it's blue.

 

Do a compression test then a leakdown test

 

At a minimum rings, bearings, gaskets and seals.

 

Where would I go about having these tests run?

 

You could do the tests yourself. Get yourself a compression tester. Make sure you unhook power to the distributor before testing. Start with the first cylinder, and work your way across all of them.

Here is ericthecarguy's tutorial video, it outlines everything.
