Burning oil on idle, and rpm drop

So i HAVE searched for this, but i cant really find an answer as to what, id like to pinpoint this as best as possible before making any decisions as to what plan of action to take,

but my car is starting to smoke more since ive gotten it, i dont drive it hard TOO much, only very seldomly, ive only redlined twice in like 2 months (which actually WAS necessary because idiots where i live like to run red lights, so i had to get on it to avoid getting hit) , and when im getting on the freeway i like to shift around 5000rpm out of second, and usually 4500-4000 through the rest, so i dont think thats bad for getting on the freeway, but ive started to notice some smoke out the exhaust, and it looks like its spitting oil.

my exhaust does smell like its running rich (which is odd because my injectors are going bad, they like to stick, so it would seem like theyre running lean).

its a b20a5, its smoking slightly at idle (puffs occasionally, almost as if its only a certain cylinder), and it goes away when you give it gas, but right as the rpms start to go down it spits a larger puff, then goes back to the aforementioned pattern when it goes back to idling. when it revs, the smoke briefly stops, but it starts spitting what looks like oil, maybe water? my tailpipe is charcoal black.

when i DO get on it, ive never noticed any clouding or hazing of blue tint smoke, and my friend has followed me onto the freeway and he said he never saw it puff once, so i dont think its the rings (god i hope not...).

Ive had friends tell me my valves could need adjusting, which i know already cause they do make some clatter, and ive read it could be valve guide seals.

Sorry for such a long post, but i like to be as detailed as possible so people who read actually have a decent idea of whats going on. I just want to know cause im about to have the timing belt , water pump, and valves adjusted, and my mechanic cuts price if hes already going to have something done that needs to be done in order to do something else (ex. hes cutting 60% off my valve adjustment because hes already going to have to take the valve cover off anyway to do the timing belt, etc.). I just want to know if i should have him throw any other work on.

ANY help/input would be greatly appreciated

Re: Burning oil on idle, and rpm drop

yeah, theyre ticking ALOT. if im starting from a stop, theyll make all sorts of damn noise, then they will quiet down once your cruising, and then if you need to give it more gas to speed up theyll start making noise again... seems to be only when the motor demands more fuel pressure. you can also hear a tick from them every once in awhile at an idle.

ANYWAYS back on topic, cant some mechanics change stem seals without pulling the head? ive heard theres a compression tool that you can use, it plugs in where the spark plugs go and puts pressure in the cylinder to hold the valve up, then you can take the spring off and change the seal? a friend told me to do that for a pos jeep i had, but he said if the valve fell then you had to pull the head...

Re: Burning oil on idle, and rpm drop

That tool is available. It just plugs into your spark plug hole to keep pressure on the valves.Get the right spring compressor and make sure each piston is at TDC.
