Supra Knock?

[Suprakidd1]

next tme just plz shut off the engine theres no need to rev it and ruin the block like that.

[MrEfack7861]

Let's be smart about this every one who owns a mk3 7m gte go buy a MHG and torque it down to 80ftlbs if you do not have the money for some arp's MGH timing belt just torque them to 80 it doesn't blow as easily and is just the easiest and pain free way 7ms are good engines but not many know how to treat them

[aamt07]

BTW.... eman2289 dont research anymore! Your invaluable info is making you look stupid! Get off the computer all together or just keep your comments to yourself. lmao sooooo stupid! Obviously you guy have never owned a chevy 305! That is a POS! The 7m is strong if you can put the right head gasket on it the 1st time! you go cheap your going to get what you pay for!

[aamt07]

PART 2.. The way you get around that is by getting a better head gasket not some little cheap crap one! The 7mgte Can be a good engine for those who have never owned one of these cars! The way I know its a rod is I had the same problem only thing is YOU DONT REV IT UP LIKE THAT!!!! You might end up scaring the cylinder walls, cracking block, pistons, cams, crankshaft, everything major in the engine! If you didnt do anything to to engine your a lucky person and shows u how strong a 7m is!

[macunicorn]

motor is done.

[mustangrules]

did you accadently put disel in it?? lol jk

[doggfish55]

ROD ROD ROD ROD ROD ROD

[slinq]

lol at everyone that lets coolent into there oil and think a head gasket will fix it whell yah it will fix it but if you got coolent into your oil your fked and need new bearings PERIOD not just a new gasket

[MARooNSUPRaMK3]

Fucking 7ms............1j

[adrenatek]

I had a '89 mkiii, I put in ARP headstuds fixed the head gasket problem, about 4 months later started having this exact same noise. turned out to be rod knock also. i'll never own a car with a 7MJTE again, such a POS motor. everything that can go wrong with it, will.

[enigmaPL]

sounds painful =\

and to those saying swap for 2jz or 7m=fail

first off the only issue with 7m's is the headgasket, once thats taken care of its a hell of a motor, with great potential

almost everyone gets off on the wrong foot with their 7m, but if youre patient enough to start over, you'll sure as hell be glad you didnt swap

[MARooNSUPRaMK3]

My 87 turbo has a rod knock....... going 1J =)

[Metalwhore89]

7mgte=Fail

[hellsdeadjuggalo]

broken muffler bearing... :D jk

[eman2289]

You guys should do some reading before talking. 7Ms are notorious for blowing head gaskets, due to an error by toyota on the head bolt torque specs. Once the headgasket starts to leak, it causes coolant to leak into the cyls/ oil, or wherever it wants to. Causing the knock. Ask any person that knows anything about these motors, and you would find that they are notorious for rod knock and BHGs.

[polishgangsta99]

yes they are lol ive been through 3 headgaskets on my old 7m thats not turbo though is it?? that sucks man but try putting in royal purple its just a mild knock and royal purple fixes everything lmao

[hellsdeadjuggalo]

its a turbo the n/a dont have that much intake tubing or the coil pack cover the n/a's use a dizzy

[doubletap85]

This sounds like a dodge caravan with 150K kms on it.

[eman2289]

Rich kids? ha. have you priced an mkiii supra at any point in your lifetime? its a 20 year old car. its probably more expensive than your sweet "jdm" civic, but its not a "rich kids" car.

[boongtown]

its stupid ass rich kids like yaself who make me feel so much betta about who i am

[rey0176]

blew it up....done...spun bearing is a knock u fuckin ass..thats what u get when u dont change the oil when ur suppose to..or run it in low levels....

[JayDM93]

ya damn right you fuccin prick!

[doubletap85]

or very high levels and aerate the oil starving the bearings. either way, dumb. takes some stupidity to cause this.

[KONARIDER909]

spun bearing

[authmaax]

what you did about that?

you fixed it?

[tytusracing]

my 7mgte is doing exactly the same since today but the most weird thing is that i have just rebuild it totally!and he keeps doing this!I've drived it about 3days smoothly and knock is back!!?why?

[AlChanning]

mate did you put new bigend shells on to the original crankshaft, the reason I ask is that I have the Supra's little brother "MR2" which had the same problem, like you I did a full rebuild of the engine, I was advised by Toyota to have the crankshaft reground otherwise the problem will come back if I had just replaced the bigend shells only, and they were right

[XSupraXManX]

So what caused the problem? Cause I have the Supra's other little brother, the Celica and its got the same noise, so is it like a spun bearing?

[becauseiwanna666]

we shall call him.... mini desiel!

[eman2289]

yea it was rod knock.

[spikederailed]

I 7M bit the dust and it wasnt even a head gasket. How bad was the crank?

[SupraJZGTE]

my 7mge has a rod knock...should i fix it or swap for 7mgte???

[1extremeking]

@SupraJZGTE  7mgte FTW...im putting together a GTE swap for my 89 right now. Its not that hard if you know what your doing, RESEARCH is key!!!

[danielalien]

rod knock

[zcomputerwiz]

Did you find out what the problem is? I have a car with a similar sound, but it seems to be a bit more persistent.

(posted video in response)

[viralthings]

It's someone with a machine gun inside your engine.

[7mgtesup]

Sounds like a diesel lol

[90Turbo7m]

naw guys, it ran out of vtec thats why.

[ShatteredSin666]

I didnt know toyota was a honda dumbass

[90Turbo7m]

i was being sarcastic ya emotional dumbass.

[NizmoFreak]

You guys are all idiots. its definitely rod knock

[mulkkerson]

wrist pin knock

[LordAkron]

Sounds like exhaust manifold rattle...

[Mrx2002]

That is rod knock you can hear it when revved.

[n240sxfnatic]

Put a long screw driver up to the head. Put ur ear up to it and feel if the vibration gets worse when u rev it. If it does than its in the head if not try the bottom end. If it is rod knock some people can actually use this technique to tell you which rod it is.

[ZenkiAE86]

im sure its a valve tap, rod knock i belive is ALOT louder, well at least it wasn't loud when im listenin to this.

[kgriggs75]

wrist pin knock?

[supsupra]

could be a loose pully for something

[civic147741]
