It's official, my Supra hates me.

[annoyingrob]

how the hell did you do that?????

i guess my "good luck" really worked?

was it hard? i'd love to know all about it, if i could do that i would!!

Yeah, thanks for the good luck

What I did was unbolt the motor mounts, and my intake piping. Then, I clipped my engine hoist onto the front hook of the motor, and used it to pull the motor up. The front of the motor ended up moving up about 2 inches. This gave me enough clearance to unbolt the pan, and slide it back, around the crossmember and steering rack.

You're very crafty with the Supra!!!:biglaugh:




That or you're a liar. ::hang::

:hsugh:

 

[annoyingrob]

Things look good!!!!!!

I'm not completely finished as I only had an hour to work on it today, but none of the rod bearings are spun, and the three crank bearings I've looked at were good too. Only 4 main bearings left to check and clearance, but I have a good feeling that they will be good.

Front main bearing clearance: .051mm, way out of spec. This is definitely helping with the knock. Now to finish up, and see if I can find some more bad bearings.

 

[annoyingrob]

Aaaaaaaaaand.........

The bearings are good. In fact, 6 of the 7 main bearings are within spec. In fact, some of them still look new. I'm going to leave the crank bearings, just replace the front one which is now way out of spec.

Rod bearings are a different story. I've sized the rod bearings, and will order new ones on monday. Assuming it should take a week and a half to get them here. Two weeks, and my Supra should be back on the road.

glad to hear it!

 

[Figit090]

dang the fact your engine is not a 7m totally slipped my mind. GAH!

that means my issue will probably be unfixable without subframe being dropped or something.

 

[garagefujimoto]

Only frickin Rob rebuilds his engines in the car

 

[Figit090]

maybe that's why he's "ANNOYINGrob"? hahaha

 

[annoyingrob]

Sweet. I got my new bearings today, installed all of them, and started it up!

.....and......it's still knocking

















So I did some investigation. Long story short, my pressure plate is loose. All of this work, and it was my damn pressure plate. Ah well, I guess I feel good knowing I have a fresh bottom end.

 

[Poodles]

ROFL

replace the pressure plate bolts if I where you, they like to stretch pretty bad... (especially when you let some cletus do the work)

 

[Figit090]

wow...that sucks. but yeah at least you have peace of mind on the rods....and one was outta spec right? i say good for you!

so is this pressure plate problem common? is there any way to differentiate between a problem with it and a problem with rods?

i have excessive vibration sometimes and i can really feel it in the clutch pedal when i depress the pedal and rev around in the 2-3k rpm range. what was it like for you??

i'm not sure what's worse...clutch issues or rod knock.

 

[annoyingrob]

Yeah, that sounds like what I had. I could feel it in the pedal, and the shifter (and everything else too, solid motor mounts ). Take off the access cover, and watch the pressure plate, see if it wobbles.

I don't think it's common, probably me not tightening them down enough. I may replace them like was sugested. a 3200lb pressure plate puts a little force on them

 

[Figit090]

access cover???

can i do anything without a ton of work under the car? do i have to remove the tranny?

i'd TOTALLY see... because man it only makes noise sometimes. its consistent but sometimes she revs smooth as butter. then sometimes it will feel really rough like something is loose.

not to mention i can't seem to get consistent with my clutchwork. i've had the car over a year and i'm still not that great with the clutch....i mean i'm alright but i dunno....some days i'm just off i guess. it would rock if it was just something loose...

 

[Poodles]

yes, you can retorque them without removing the engine or tranny...

pop the inspection plates off and have a look.

You might have a lose clutch fork fulcrum, ect...

 

[Figit090]

WOW i hope so. i'll have such a nicer time with my supra if i can enjoy spirited driving without worrying about completely spinning a bearing....

where shall i look for the inspection plate(s)? do i need to take any precautions, or is it just a metal plate with no seals or fluids or things behind it that i need to know about?

i'm kinda excited. lol.....

would rod knock make a vibration in the clutch pedal and shifter when i rev with the clutch pedal depressed? because that's what i'm getting...

 

[annoyingrob]

There are two metal plates, one bolted to each side of the bellhousing. Those are the access panels. Two 12mm bolts, and they come off. It's about as easy as it can be.

There are no fluids, or seals to worry about. You can reach inside these openings and tihten down the pressure plate fairly easy. You'll have to rotate teh motor a little to get to all of the bolts, but it shouldn't take more then 10 minutes, 20 if you don't know what you're doing.

I've never dealt with rod knock personally, but if the rod bearings are bad, and the mains are still good, I don't think it would vibrate that much at all.

 

[Figit090]

well i dont know which bearings usually fail all i know is one of the bearings in there go bad. if you mean mains by crank bearings i'm not worried about those. but there's something....

i'll get the car up on jacks again this weekend for a look-see at my clutch. i hope it's an easy fix! i'll be so happy you dont even know.

 

[annoyingrob]

So I tightened down the pressure plate, and nothing changed.......


....hahaha, the flywheel came loose. I don't know how, I had torqued it down, and put locktite on the bolts. Anyways, I managed to tighten it back down with everything still in the car. It was a pain in the ass, but less of a pain then dropping the tranny.

It drives again, I'm so happy. The turbo's leaking a lot of oil now though. I'm going to park it for the winter soon, and send the turbo off.

 

[garagefujimoto]

Did you use new bolts when you put the flywheel in?

I didn and they came with this red shit on the threads already when I got them from Toyota, maybe that helps

 

[Figit090]

red shit is probably some sort of thread lock. maybe it just clogs the threads or it reacts to heat when the car is used and locks up.

so you still have a knock? maybe your main crank pulley is loose!? check it.

or are you saying you fixed it but it was actually your flywheel?

can that be done from the check plates as well?

they are on the sides of the tranny correct? i think i saw one without jacking up the car...


OH CRAP what engine and tranny are you running?
