Mach201-15-2006, 05:43 PMSup everyone, This is my first post so be easy, Here's whats going on :

Car : 92 MR2 N/A manual trans

Symptoms: it has a severe rattling noise coming from the engine bay, the car will start and run but it wont go past 20 mph and it overheats very irregularly with no constant other than If I run it past like 4500 RPM's for a while under normal driving conditions. Before the rattling I had taken out the radiator and blown the dust and dirt out of the fins, replaced the thermostat an changed the radiator fluid. And the shifter will stick pretty regularly when changing gears. I also bought the car as a salvage title with water damage.

What I think: I believe its either some type of gear damage or syncro problems and a blown or warped head gaskett.

Parts: a spare 5sfe block, 5S pistons rods and crank. I also have stock compression forged Arias pistons (which I have placed on sale) and a Turbo exaust manifold and a turbo trust muffler.

THE PROBLEM AND QUESTION: I know the engine bay has a lot of problems stuff I know I cant fix myself and things that havent even broken yet (as its a salvage car Ive had lots of people say they wouldnt touch it). I need to know if I should try to find a cheap engine rebuild or used engine shop and give them the forged pistons and hope that the tranny isnt big trouble and they charge me minimum 3-500 to fix it or anything else I know of. and buy a 1500 dollar turbo kit for the 5sfe/ OR give ATS racing down here in Texas my 2.2 crank and forged pistons for a 400 core and pay 3100 for a 3sgte clip swap w/tranny.

Please help I have no idea what im doing.. Ive been trying to get this project together for 3 years

THE CATCH: I only have 3000$ to work with as I just bought a house and need to keep some money in my pocket. Weasy2k01-15-2006, 06:19 PMwell that 3 grand will limit you right away...

I see you said you changed the coolent...MR2's are VERY picky in how its done...if its done incorrectly there iwll be bubbles int eh system and overheat will occur. I usualy tilt the rear of the car off the ground and shove a funnel into the filler neck and start hte car...pour coolent/water mix into the funnel until it wont take anymore....then leave the car running and once it warms up continue to poor water in there and have your heater on the HOT position. Bubble swill come out and start to bleed. There are other ways but thats how i do it and has worked everytime.

The rattlig sound can be something hitting you have to locate the sound better then just saying "engine bay" cause there alot of shit in there :)

Also did you replace the tranny fluid at all? water dmaage could mean the tranny is full of water or something...heck iw ould replace all fluids in that car.

This is a start...i gotta run but ill type more later...

welcome to the board Mach201-15-2006, 07:56 PMI will have to try that because Ive just been pouring it into the filler and the white container area. I actually just went outside to move it around (apartment complex doesnt like that I dont drive it, cant wait to move into my house) I drove a little around the apartment complex and pushing the gas its like an on off switch. Either have to floor it or nothing happens. As far as narrowing down where it is.. its soo loud its gonna be tough but im lookin for a stethescope. As far as a 3sgt3 swap and tune, is it worth 3100? Mister2.201-15-2006, 08:01 PMOverheating is most likely cause you have air in the coolant system as Weasy pointed out. The ratteling is probably the Exhaust Manifold Heat Shield.

For 3K that's a hard one. If you can manage to get your engine running correctly and get all your normal bugs worked out, I would use that 3K on suspension upgrades and anything else that's just worn out, like interior parts. Once you get the car in pristine shape, then consider doing a 3S swap.

If the car is in overall good shape including your suspension and you really want more power, I would look into buying a whole rear second gen turbo clip.

good tips....forgot about the heat shield :) Mach201-15-2006, 11:30 PM.

Forgive my newbiness on the reply!!

I aprecciate all of you all's responses by the way keep em coming (always had good relationships on message boards with toyota entusiests)

I removed and put back the heat sheild, nothing seemed loose. Ive also got underneath to check the exaust sytem for any funny buisness its all tight manifold to muffler.

The car is in ok shape I had to strip the interior and re do the carpet, I had to remove a lot of the panels under the dash to get to the harness and replace a lot of stuff,
I plan on using the car for track duty, but ive wanted to go boosted for SOO long its killin me. I wont have this kind of money for a looong time so im trying to go boosted or get as close as possible. My cousin is a big domestic fan but apreciates speed, he thinks 3100 for a swap is a lot. Im still not sure. Luni01-16-2006, 01:12 AMAlso, it sounds like rattling as in exhaust, or something, but sometimes the carrier bearing rattles (mine does) and it sounds like a rattly exhaust. I mention this because he also is talking about having problems with his transmission.

Mach2 what you want to do is put your car up on ramps or jackstands, start it and get underneath it and see if you can pinpoint where the rattle is coming from. The way I found mine (it actually sounded like a knock underneath it) was by pushing against the axle on the passenger side (its longer and it will flex a little if you push on it, so dont be afraid to give it some force). When I loaded it up with force the rattle went away (I had my buddy hold the throttle at 1500 rpms). But it sounded like a rattley exhaust heat shield.

You also have heat shields on the primary cat, exhaust manifold, and theres also various places down underneath it could be rattling. As for the transmission and it falling out of gear, make sure your clutch is adjusted properly (theres an adjustment screw and assembly on the pedal itself, you will have to pretzel yourself under the pedals in the front of the car, but you can see it), make sure your gear linkages are connected properly and the holding pins are in place properly (on the transmission right next to the firewall on the driver side of the car, down underneath).

Good luck with your troubleshooting.

Oh and 3100 for a swap, assuming you get EVERYTHING you need to make it work, is a good deal. Some clips are that much. So 3100 for EVERYTHING, labor, parts, etc, is a pretty good deal. Just make sure you dont get jewed on anything. When the time comes and you actually want to do it, get a list from the person, make them cover all the items they will do, and get a lead on where they are getting the engine from, take LOTS of pictures, and consult the forum. We will help you by letting you know if youre being taken or if youre getting decent stuff. Things like that.

Good luck man. Weasy2k01-16-2006, 01:59 AMthe rattle....do you have a stock cat? is it coming form there cause it could be the cat breaking apart....

do you have a huge loss of power? Mach201-16-2006, 02:52 AMTHANK YOU ALL SOO MUCH this is the most info I have had in months! Im going to look at everything tomorrow and see if any of that is whats going on LUNI! And yes WEASY everything is very stock down , and as far as powerloss it doesnt seem huge but I never take it that far or that fast, there but I will deffinetly look at that as well an get back to you. Thanks again all and I am always looking for more advise! Mister2.201-16-2006, 04:44 AMCan you describe the tone of the rattle? Mach201-16-2006, 05:36 PMCan you describe the tone of the rattle?


IF I had to compare it to something, If I had never heard the actual sound of one to differintiate the 2 I woulld say it sounds like a broken rod or something on the drive train. The 2 sound very similar. Weasy2k01-17-2006, 01:55 AMim eyeing the cat right now :) check it out and then we can go from there
THere are 2 cats one right behind the engine and one right by the muffler.... Luni01-17-2006, 11:38 AMIm actually thinking its that carrier bearing like mine is.

It sounded JUST like what hes describing. More so from under the car. Mach201-17-2006, 10:33 PMI have video of the noise, Id like to post it any suggestions. Mister2.201-17-2006, 10:41 PMHow large is the video? Mach201-18-2006, 12:48 AMHow large is the video?


7.84 meg Weasy2k01-18-2006, 12:57 AMsend it to my email

i will host it for diag purposes here.... mymr2turbo01-18-2006, 01:07 AMTry carpron.com if you haven't already uploaded pics of your car yet. I dl a video a while in the same MB range and it worked so it should do the same for you.

After reading your thread, your rattling problems seems to lye along the lines of the exhaust system....just something is loose and you have yet to pinpoint it.

About your overheating problem. I haven't dealt with the cooling system yet on an mr2 so I can't say what all to do but Weasy, Luni and Mister2.2 (I only named the three that have posted in ur thread so far) all have great knowledge so I'm sure they can help u out the most.

Steve Weasy2k01-19-2006, 12:39 PMRattle Sound Clip (http://www.sea2skytuning.com/Support/downloads/MPEG0001.ASF)

Sounds friggen nasty! I think it is your cat cause when you go to the exhaust side you really start to hear it. but wow.. Mach201-19-2006, 10:08 PMI know right Im going to check it out here soon Ive been getting home after dark lately.:undecided TomsMR201-19-2006, 10:24 PMthat sure isnt heat shield rattling.. that sounds like your valve cover is full of quarters or something! or you got piston chunks floating around, or spit a cam shim..

edit: maybe your throw out bearing exploded.. that sounds bad to me. Mister2.201-19-2006, 10:33 PMTom knows what he's talking about (usually :) ) I would try a compression test first, see how that is... If that is fine then I would remove that heat shield just for shits and maybe disconnect the exhaust, see if you can still hear it... If you still do, probably time to pull the engine and expect to replace it. TomsMR201-19-2006, 10:40 PMthats gotta be a rod man.. like a really really really really shot bearing. drain the oil and see what sorts of fun stuff comes out.. then go from there. im betting metal chunks come out. Mister2.201-19-2006, 10:41 PMTom stole my idea. Weasy2k01-20-2006, 11:11 AMi like to ease in the problems, but rod knock is the next thing i was thinking....or osmethign to that....
The more i listen to it the more i think it is something nasty like that :( PeStVic01-23-2006, 01:21 AMit sounds like a rod. thats what my brothers car sounded like when his rod started knocking. but it didnt sound THAT bad. it sounded like a steady knock, that sounds like what he said. like quarters or metal chucks rattling around.

give it a couple days to a week. if the car dies. it was the rod :-P

sorry about your luck man. when i get my mr2 i hope i dont have problems like this Weasy2k01-24-2006, 02:31 AMim sure the car was a deal tho since it was water damage Luni01-25-2006, 07:03 PMYeah, that sounds like rodknock man.

I have a sound clip of my 1.6 4afe celica with rod knock. Listen, its very similiar...

http://www.celicatech.com/luni/celirodknock.wav PHOENIX01-25-2006, 07:05 PMhey luni, i cant put my finger on it, but it sounds like there is something wrong with your engine :D Weasy2k01-25-2006, 09:30 PMhey luni, i cant put my finger on it, but it sounds like there is something wrong with your engine :D


omg can you be my mechanic :devil: :omg: Luni01-30-2006, 01:59 PMHAHA yeah Dave. Send me a 4AFE.

Hey... YOU CAN GET THAT SHIT.

Seriously Dave you should see how much you can get one of those things for. Tax season is coming, I wanna replace my celicas motor so I can DD it instead of my MR2. Powered by vBulletin® Version 4.2.5 Copyright © 2026 vBulletin Solutions Inc. All rights reserved.
