WJ where is the coolant puddle located with the car parked?

Also if you have never replaced the Bypass hose under the Alternator, please check it

There is also the possibility of a crack or cut in the hose from overflow to rad.

I had never seen it before Morty had the issue. It'* a good one to keep in mind as we take it for granted.

OHH, good idea, I have not checked that!!!! Is it possible that maybe the bottle has a leak?

Also, what is the best and easiest way to clean that bottle too look like new? I was thinking about soaking it in a bleach solution.

Take the bottle off and put a rag saturated in simple green in it and shake the h*** out of it, and then remove the rag. Just be sure to flush it with a lot of fresh water.

Yeah, that'* all I used. You might have to rinse the rag out and repeat. It depends on how dirty your bottle is. Mine wasn't too bad.

Now that WJ is good, let'* diagnose the white one now LOL. Coolant is not leaking, and oil level is not getting higher. However, I can swear that sweet smelling exhaust is there, and every once in a while when i go from a stop light i'll burn oil. Nothing much, just a little cloud left behind me. Also I am noticing fresh oil all around the intake [where visible], and on the side of the block right off the driver'* side intake seal. I don't consume any oil between oil changes. But the temp gauge is always moving around. Sometimes at idle [more hot than cold], the temp gauge will flutter, sitting at just about 1/4 then it'* like something hits the gauge and drops down a needle'* width, then comes back up again fairly quickly. It'll do that for a while, and when I am cruising, I can notice the same thing, sometimes occuring more than others. But the gauge never goes past 1/2, even in city driving. And I've lost about 1" of coolant in the overflow bottle just this week.

The car performs very well. I've noticed perhaps a bit of loss in performance, and I did just put new plugs in. The idle is odd, but is a lot better than it has been. Cold start, revs up to 2400rpm then quickly drops to about 2k, then slowly adjusts [99% sure IAC adjustment here] down to about 1500. It will idle at 1500 for about 60 seconds, then it will find it'* way down to 1200, and once it gets up to temp she'll idle at 800. But every once in a while i'll get a 2k idle no matter the temp and if I stop and start the car again it'll smooth out shortly after start.

Now that WJ is good...please start a new thread. We'll diagnose yours seperately and cleanly from his as they could be different outcomes.
