ok well i just want to know if the s13 model has a a common o-ring problem? I have a KA24DE and i had a really bad oil leak (like i had to buy more oil then gas to drive around) found and replaced the front crankshaft seal and the oil pan gasket...but after that i continued to have blueish smoke coming out of my exhaust and oil level goes down. I dont see where its leaking after cleaning no drops, no wet oily areas, nothing...someone told be that maybe its the o-rings but i hope its not but iv notice that my oil light never comes on and there is a bulb and i know it works and that the hotter the engine is the more the smoke comes out...

So if you have any ideas on how to solve the problem or if you need more details to help then let me know

If your engine is clean (no leakes etc) and you are still loosing oil then it is probably your piston rings that are shot. This means engine rebuild/replacement time.

Do a compression test and a leakdown test. that will give you an idea of how bad your engine is.

Is the smoke worse after idleing for a few minutes, such as at a traffic light? If so then it could just be the valve guide seals. That means the head should be re-done but not as expensive as an engine.
