Ok, its 5:45ish, and my Girlfriend gets off of work at 11 pm, so heres the story.... Yesturday I said to her "I'm changing the oil myself, I don't have the time to wait 3+ hours at the oil place" she replied saying that I always talk about how rotarys are so differant then my V8 in the camaro, and that I'm still learning about the RX7 and stuff, to cut it short, she said I was going to mess her car up....

::Long brag story, not really important::

So later last night her friend came down from florida, YAY right, sure, her "not boyfriend" had an Eclipse and we were getting along, so we were like "Sure might as well go race, its 3 am, no cops, fun fun" so we were hauling ***, I won, and he got kinda mad at his car because he was sure he could kick my *** with the car, so I gave him the lecture about how its not the car, but the driver, and their skill with the car that wins races, and that I have been racing for years, so I'm good, and that was his first race, so naturally he's gonna lose, and that it was no big deal.

::End of long brag story, start reading again::

Ok, so after all that, me and my Girlfriend go home, all is good, no problems when I took her to work this morning or anything, then I went to go pick up my friend to hang out (not the one I raced), and the engine started to Tink when I parked the car and left it at idle, like a 2 beat tink, and a four beat string of music (like: bummmm, Tink, bummm, tink, repeat, but without the bumm, just the tink) I don't know if it is still there at anything other then idle, cause the engine and muffler are to loud.

All I know is that its coming from the front driver side of the engine, or maybe middle, thats the problem, I can't tell, I know its on the driver side of the engine, but the engines so loud (mostly the fan, and stock exhaust) that I can't pinpoint the thing I have to look at.

Ok, this is a sloppy post, but I really need help, if my girlfriend thinks I messed her car up, shes going to say it was the oil change, then BAM, I'm picked on forever as the guy that blew an engine up by changing the oil.

Did you overrev the car last night?

 

yea, what did you shift at? does it still have the same power? if it feels sluggish then that would help. if it's driving normal still though and idling ok, just a tink, then it could be something external??? i dunno. need more info.

 

its your a/c clutch going on and off...... wonder if the wire has a short or if its on its last leg/

 

Ok, upon further inspection, it sounds more like a flapping or clicking, like when you stick a card in the spokes of a bike, but with the beat I originally explained, and I'm pretty sure that its coming from the front of the engine, AC maybe, but we never use the AC, so I don't know why it would be messed up now.

And yes, I revved fairly high last night, but not to high, I shifted at about 5k rpms (I'm used to V8s redlining there, so its just instinct) and the car seems to drive the same, theres absolutely no problem with its manner on the road minus the clicking, flappy sound.

how would I go about checking, or taking the AC off the car without making the electric thing somethings wrong?

Thank you guys for the quick replies

Hmmm. Is it a real problem? Or are you just hearing things yu didnt hear b4? Its not runing any different right? 5K shifting is being gentle on a rotary.

 

Its not a "real problem", I'm just worried about it, I have never heard it before, and I know that it means something needs fixed, What I'm ultimately worried about is my girlfriend hearing it one day, shes not as understanding about everything, she says she doesn't want to know "every little thing about my car" and as such, she hears alittle flapping, and she will think I blew the engine up, and that will mean sleeping in the living room

so any help would be good, even if it is the Ac, I need to find a way to make it stop the noise

What if he had overrevved the motor and it was feeling sluggish... i am asking because my car just hasn't been teh same... not it isn't slow or anything like that... but it just isn't the car it was when i bought it... i have never revved my engine over 7.5k rpm by the way.

how many miles does this big bad V8 have on it. could it just be the valves starting to tap. do you have enough oil in it, i know a lot of engines like to tap if they are a quart low or somewhere around there. tapping valves is no big deal tho, they all get loose over time.

 

i think we are talking about an RX-7 at the moment, did you check if mebbe something was rubbing against the fan? Might aswell check all of the belts aswell.
That dood you raced must be a HORRIBLE driver considering you were shifting at 5K and still beat him. I am impressed.

 

Unplug your A/C compressor and see if that cures your problem.

 

Is it car with power steering? I know my idler pulley for the A/C and P/S sometimes makes a funny noise. I think the bearing is getting ready to ****. I sprayed the middle of the pulley (where the bearing is) with WD-40 and it quieted down. Try removing your A/C- P/S belt and see if it quiets down.

 

Unplugging it wont work. The pulley is still turning, you need to remove the belt.

 

My A/C compressor in my Camaro was doing the same thing, ticking from turning off and on.

 

Ah, well in Teds (The guy I raced) defence, it was his first race, he was worried about being caught (and it was an automatic tranny)

My girlfriend found out about the engine, she took it well but said that I better fix it today, as she has along trip ahead of her later today, about 200 miles, to go pick up a friend.

I'm gonna try to take the belt off the AC when she brings the car back from work today, and see if that works, then I'll probably check for any obstructions or rubbing.

Yea, see, Mentioning the ticking from the AC compressor in f-bodies, I was thinking the AC compressor on the Rx7 would sound the same when it goes bad, But this sound is loud, like you can hear it at idle over the engine and muffler from about 5 to 10 feet away, all be it at about 10 feet you don't notice it unless your looking for it, it doesn't sound like the Camaro AC ticking that I'm used to, so thats whats making me worried, plus, in F-bodies, the ticking stops when you turn the AC off (for the most part) the flapping I'm hearing is with the AC on and off.

I did just change the oil over, I stuck in 4 quarts of oil, I'm not to sure how much oil I should put in (that sounds really stupid, but really, that is a tiny *** oil pan and engine) should I put more in? my manual has a smudged oil spot over the amount of oil to put in
It is very close to the F on the dipstick, but should I fill it all the way up?


-Karma

 

dunno about the oil.... read the damn dipstick... lol


but it might be your alternator, or power steering pump (if you have power steering) well, it might be dry.....


Look for rubbing first.... then check the belts


followthe sound under the hood when its running......

 

you know that little bolt that goes on the oil pan, your suppose to put it back in By the way did you grease the conveyor belt? also did you feed the little mouse running on the belt?

 

Oh man! I forgot to feed the mouse!
**Runs**
**comes back**
Nope, the mouse is all good, I havent had time yet to take the AC off, so the noise is still there, I will do in about an hour

Hope it works, I would hate to have to replace the mouse, sure, hes got alot of miles, but hes just so damned cute.

I realize it was only when the air in F-bodies is turned on, but there could be a short causing it to turn off and on while the switch is off. Air conditioning isn't my strong point, i've always just removed it. The compressor is mostly likely smaller in the Rx-7 causing it to tick more rapidly. It's probably not your problem, but it is a possiblity, never rule out possibilities.

 

"I know its on the driver side of the engine, but the engines so loud (mostly the fan, and stock exhaust) that I can't pinpoint the thing I have to look at."

I don't know about the tinking, but the whooshing might be a stuck fan clutch. The 85 GSL that I bought to replace my 84 that got rear ended sounded like one of those turbine cars they had at Indy in the mid 60s. At first I figured it must be that the cats make the engine sound funny, but after I replaced the cats with a bonez presilencer, the whooshing started to bother me. I discovered that the fan coweling was separated from the radiator by about an inch because the bracket on the radiator was gone, so I used some metal strapping to cinch it to one of the body boltsup front. Nice and tight but still some whooshing. Then I noticed that the fan seemed to be working harder than it needed to be and started thinking it might be the fan clutch, even though I had already checked this when I first bought the car - it spun easily with the engine off. I wasn't willing to stick something in the fan when it was running to see if the clutch really was stuck, so I switched out the clutch for the one from my 84. Problem solved. Now you here the bonez presilencer (sweet) and no whoosh.
