So when i got home tonight, i heard a clunking nosie so i parked it and left it running. i opend the hood and i hear this noise, its comparably to a rod knock sound. but i cant tell if its comming from the motor ot the echaust right in that area and its dark so i cant see if the exhaust is hitting somthing. do rotarys make and "knocking" nosie if they are about to blow? im kind of worried.. any one have any ideas before i panic about somthing that may be no big deal?

WTF gives are all 1st gens going to hell or what this is like the third one in two days!!!!

scott_06

so i take it thats not a good thing this noise is their?

yetterben

it really depends. If it indeed sounds like a rod knock that friggin loud than i would assume its about to kick it. I have never heard a rotary knock or really ping. I have been trying to get people to post videos of knocking pinging cars for awhile. Mine has a small ping at idle but i think its in the exhasut on my setup. But if its that loud its probally doomed post a video on photobucket or you tube with a link here!

djessence

are we serious. First we have oh **** my carb is dead in like 8 threads yesterday and now its oh, **** my rotor has potentially spun a bearing!. I think everyone might wanna stop driving for like a couple days haha


yea read the "sounds like a rod knock" thread on the 1st page of the 1st gen forum.

too funny, but not really. Could be time for a rebuild, but seriously read that thread and we can determine more from the info you can provide after reading it.

i would post a vid but my exhaust has major leaks and its hard to hear. when i drive it, it gets louder. =( spun bearing.. soo.. if thats the case, how long could she run for?

scott_06

is there any type of test i can do to find out anything in side is messed up?

djessence

can try a compression test. Might tell you if youve lost a seal but i dont think its conclusive to a spun bearing.

scott_06

i dont have a compression gage, is ther a differnt way to check it? back yard style?

bugman1973

could be a pilot bearing

scott_06

explain^^ im still new to the rx7's im not to smart on this things yet.

djessence

its the needle like bearing that is pressed into the e-shaft (crank).

scott_06

is there a way i can check it? also it that the bearing that come from the crank to the trans?

djessence

someone else will have to answer, ive exhausted the knowledge i have atm lol

someone help my man out!

bugman1973

yeah its in between the e-shaft and transmission. they make noise when the go bad. you basically have to pull the transmission out to change it while you are there i would suggest a new clutch pack as well. if you don't do that you will have the same issues down the road so might as well do it.

scott_06

lol okay. thanks for the info tho man! i guess i will have to look at it after work tomm. damit

scott_06

would this make that noise i was explaining? i did notice some more vibrations in my shifter while i was driving but didnt think anything of it.

scott_06

Jimmy! im mad lol.

I dont think I would freak out just off of what you've described. Does the car start back up now? If it starts does the exhaust smell rich and does the engine look like it wants to jump out? If it does, its possible your leading ignitor went out. Switch the trailing ignitor with the leading (on side of distributor, look up which is which) and see if that smooths things out.
When mine went out it was in traffic and the clunk was my engine starting to run like complete crap!

if its your bearing you should see metal shavings in the oil, IIRC.

the oil will look shiny. run a magnet through it and see if you pick up a lot of small particles.

im having a similar issue, but i think mine is spark related.

Is the 7 starting up normally? Or is it having a hard time?
Don't forget to check your engine and transmission mount.

scott_06

ya, its starts up perfect. it was dark last night so i couldnt tell if there were shavings in the oil, or if the motor was shacking alot. when i get on from work im going to check all that. and switch the ignitor. may be i will get lucky. thanks for the info guys!

djessence

see if you can get a video/sound clip.

scott_06

okay, i just got home from work, im going to start it up and drive it down the street to my friends house. (cant work on cars in my appartment) im going to look at the oil, mounts. my buddy has a phone that can take a vid. so i will post it up here in like 2 hours oe so.
