Burning oil, other issues. 2000 Base
I just purchased a 2000 Prelude Base. Great condition, 1 owner and all records from service. So first of all, I seem to be burning oil at a fast rate. I know these engines do generally but since I have bought it, I have added over a quart of oil to it. I believe that I have around 300 miles to it so far. Sometimes it's hard to read the dip stick but I am noticing it going down quickly. The oil was replaced right before I purchased it and I believe the oil is conventional 5w30, but I am planning to change to synthetic. Right after I bought the car I got the timing belt job done because it is at 102000 miles. Now in the past week I have noticed a few times that blue smoke has come out of the exhaust. I never saw this happen before, but I noticed it in the review mirror. This would last about 3 seconds before it stops and looks normal. I haven't done a compression test yet, but I have a bad feeling that the piston rings are probably bad. I really cant have that be what it is. If anyone has any insight to this and whatever else I can do to fix, please let me know.
There are a couple of other issues that I have noticed when driving. Maybe someone can help with these. First, the revs hang after I clutch in. For example, I clutch in to shift at the "sweet spot" which i guess is like 3500 rpm and it will stay there and drop slowly and then eventually drop faster. This just makes it impossible for smooth, quick shifts. Then there is the issue with accelerating. It just isn't smooth or linear. Ill be driving normal (just accelerating with traffic) and ill have a delay or surging when accelerating. So I'll shift from 2nd into 3rd, and after releasing the clutch, ill hit the pedal and it wont do anything for a second and then all the sudden it goes. And in general, acceleration is just not smooth. One other thing, in the left front, I notice a knock when I accelerate and its cold. I think its the upper control arm bushing. Please let me know if you have experienced any of this.

Re: Burning oil, other issues. 2000 Base
do you have any oil leaks?
bad valve seals cause some oil burning and bad piston rings cause major oil burning
sadly bad piston rings are more expensive to change since you have to get your block honed
with those miles if your clutch havent been ever replaced, maybe time has come for that? is ignition parts ever changed? have you checkd that throttle cable is properly tight?

Re: Burning oil, other issues. 2000 Base
I would venture that with that many miles in 17 years, the car was either not driven much, or has been parked for some time.
I would guess valve seals, and obviously fix any leaks. Might be worth either pulling injectors and having them cleaned, or at running a can of BG 44K through the fuel system, it's the ONLY cleaner I would use.
Maybe just check the throttle return spring, and how freely the throttle cable moves. Also the IAC could be sticking and hanging out open too long, might need to be cleaned out.

Re: Burning oil, other issues. 2000 Base
The valve seals unfortunately involve taking the valve cover back off, along with removal of the cams etc. Much easier than new rings, which involves a full teardown, and basically a complete rebuild of the engine.
Does the car rev up and down fine out of gear i.e. just sitting, or does the throttle hang and drop revs slowly then as well. are there any problems with gear engagement when you shift, or any thing like that?

Re: Burning oil, other issues. 2000 Base
Okay, so what ones were done for the timing belt service. I saw that they were valve seals. Anyway I don't remember why these seals were brought up. Maybe because of the oil leak? I'm pretty sure thats coming from the oil pan only.

Re: Burning oil, other issues. 2000 Base
are you sure that they werent spark plug seals?
seal kit #1 should be changed when doing timing belt job since its possible that they have some wear also

Re: Burning oil, other issues. 2000 Base
A good rule of thumb when doing a timing belt job is to replace the surrounding seals (OEM) within the area since it's already opened up. Cam cap, cam seal, front main and balance shaft seal.
