Clutch slipping/throwout bearing gone or bad?
Hi guys.
Not my car, but a friend's. He, also has an 88 gxl. I drove his car today, because he was telling me he had bad grinds going from 2nd to 3rd.. and when going into neutral(it'll grind, or make a really bad squeaking noise sorta). It didn't do it to me - but I believe him.
Putting the car into gear, and putting the clutch in, I noticed that his clutch was VERY smooth to push in. Well, not so as smooth, but easy... not like any normal clutches, I guess. Anytime you change gears, the clutch would make a smemi-squishy noise. To me, that doesn't sound good - and I told him I think it's his clutch slipping. I asked him how long ago did he change the clutch, and he told me about 2 months ago.
He also mentioned that before he got the car, the owner before hand did something - and the throwout bearing broke. Or something. I dunno. We're gonna take out his engine this weekend and take apart the clutch/flywheel and see what's going on. Anything either of us should look for in the process?
While all this is happening - we're also trying to find out where he's having the exhaust leak. You can hear it everytime you get on it.... I am thinking it's down near the cats... or whatever that long piping is.

If hes having trouble getting it into gear, its probably the slave cylinder. Its unlikely ( though I have seen it happen ) for the throwout bearing to break off on the input shaft.
Now that I read it again, it sounds like hes just having a problem from 2->3 right? If thats the case, its probably just a bad syncro on that gear.

Bumpity.....
It's not really all of 2nd and 3rd gear. It's more like of everything. The clutch doesn't feel right, too soft, makes kinda like a squishing noise whenever you push the clutch in.
If he has a camera and willing to let me use it to take pics of it - I'll show you guys, otherwise... I'll find some other way to explain what it's doing.
Sometimes it's hard to get into gear, sometimes it's not. I think this weekend we're gonna take it apart... and look at the clutch/flywheel and see if anything doesn't look correct. I think I'm also gonna put redline in his tranny and see if at all it helps.
edit: how do you figure the throwout bearing is bad or going to go?

If the throwout bearing is going bad, itll normally squeak some when the clutch is engaged ( your foot OFF the pedal )
Maybe when he changed the clutch he got some air in the lines?

Okay thank you. I'll check that out tomorrow. Is there anything else I should look for? Or that'll tell me instantly that this X is wrong... ?

If you push the pedal in and hear a humming sort of noise, it is just the pilot bearing. My new one did that for quite a while and then it went away, maybe worn away? Not that unusual. If it is a new clutch give it a little time to break in.

Well, It's not quiet such a humming noise but a really bad squeaking when the clutch is gaged (or pushed in). The pedal went just about to the floor before any resistance was felt, the car was very difficult to drive for me, as I'm used to a fairly hard clutch ( if that makes much sense).
How might one tell if the shifter bushings need to be replaced? Pics are greatly appreciated. If they are bad - where do you go to get them replaced? How much? Etc.
Hm.. thinking of other problems with the car that I can help him on....
Oh, the sunroof. I had the same problem of it not closing. Though, his probably is the fact it WON'T open at all.. He can get it to crack a little, but it won't budge any more. Would it help and work afterwards if you manually open and re-close it?
Power windows - The passanger side. Won't budge. When he bought the car, it would close half-way, and just one day it closed all the way. After that day... it wouldn't go back down at all. It's quite obvious that the switch and everything has been altered a few times, as it's not a stock switch. He altered it I believe twice, and still nothing. Any suggestions on what to do next?
Hm..I think that's it for now.. besides the gasket that I'm gonna help him change. About how big is the gasket? It's on the passanger side near the knock sensor (or boost sensor? One of the two)
His cats have been taken off, and (I think, either..) a straight pipe or high flow cat was replaced. Anyways, again, much help appreciated!

The clutch problem is caused by a bad master or slave cylinder. Replace both, because if you replace only one, the other will fail quickly soon after.
The sunroof needs to be cleaned and lubricated. Search the forum and instructions will be found. Common problem.
The power window problem is probably a switch issue. Replace both the drivers and passenger switch, as more than likely both are bad.

As for the sunroof, use the manual crank and see if it frees up.

Okay thanks.
I'm pretty sure both run pretty expensive
Check your PM.
Well, like I asked aaron in PM - Can you get the master or slave cylinder at your local parts store - or does it have to be specially ordered?
Don't our cars use the master slave hydrolic systems for clutch operation?

Okay, about the shifter bushings. I forget now - but tomorrow when we go over it more, I'll drive it again and see if it does. In any case, if it does, HOW do you change it?
I pretty much know how to fix the sunroof, but I wasn't sure if it'd be the samething as trying to close it manually, it would work the same way as trying to open it manually.

Check for leaks around the hydraulics, but if they are leaking internally the only way to check is to swap for known good ones.
The sunroof is probably just stuck, so manually move it, then lubricate and clean the tracks and cables. Use a lithium based grease.

Mazdatrix faq has a step by step set of instructions on the bushings so that should be a breeze. I strongly suggest you looking at the FSM online before you deal with the master and slave cylinders.
