loud knocking

[Supra2NR]

i dunt know what happend to me this time, god doesnt like me

i was driving home last night then all of a sudden a loud knockin sound came from the engine bay, first it started when im in 3000 rpms, then it got to 2000 then lower and lower, then my car shut down while i was in the middle of the road, almost getting me to an accident

i got it to crawl into a parking lot , it wouldnt even crank, i left it there for the night

came back this morning, i got it to crank (barely) and i limpd it home, it sounds like its the pistons, i dont know tho, it sounds like its deprived of oil, cuz its really knockin hard as hell as in when you hit metal in to a bench sander,

the starting problem i dunt get since it giving me a 12v reading

the knockin i dunt know what can b causing it

so you know i have been having problems with my tranny, my gear grinds everytime i switch to 2nd, and reverse

and when i drove it the oil pressure gauge wasnt moving at all, dunt get it since i put the oil myself, dunt make fun cuz i know how to do that pls

anybody got any ideas what could be my problem this time?

...I forsee....

A part out thread...





no seriously, dude that doesnt sound good at all. My guess is that you spun the main bearings, depriving the crank of oil and the knock is rods. Time to start searching Ebay for a JDM replacement.

haha, i had the same problem 2 times in a row it is a piston, check your oil see if you have enough to lube the pistons, take apart the engine and see if anything is damaged, if somethin is then replace it asap, just yesterday i started hearing the same sound when i got home, i checked my oil, theres was barely any in there, so i changed the oil and filter, when i first start it up i would hear it but then it goes away, you could have the same problem.im scared that i damage something or loosend a piston. I have one hell of a history with my supra, first time i got it a piston was loose and shot it through the block, second engine overheated and cracked the head, 3rd engine not enough oil, i hope nothing else happens. sorry for goin off topic but good luck with your car man.

i dont know if i should be sad or happy,

i should be sad cuz this fucked up,

one questions how many quartz of oil do you guys put in your car?

but im happy cuz, new lightweight pistons here i come, new rods come on down, maybe even a new fuel rail, while im at it a new MHG, i can get the bigger injectors while im doing this, yeah cuz the knockin was horrible

but sori guys, no part-out thread yet, but there's gonna b a revival though

i put almost 5 quarts i have it where theres some oil left in the bottle. it says the capacity is like 4.7 quarts i think. but i want to change the pistons and hte rods but no money!

[Supra2NR]

what do you guys think of those lightweight pistons heads?

and what kind of a/m rods should i looking for

any brands? any names in particular?

i put 4 quarts of oil, do you guys think that was too short of what the car needed thats why i got this problem now?

Only if thats all you ever did. Have you heard of a dipstick? (as in..."Enus, YOU DIPSTICK! Cud ya ya! )

and there is one other thing on our cars that helps determine if they have enough oil...its called an oil pressure gauge...Its just to the left of your voltmeter...its got this cool little icon on it that looks like an oil can! Ever seen it?

Im just razzin ya bro! but seriously, if you think you were low on oil, then my guess is...you were low on oil. Im also willing to bet that right before this happened you were going through the gears or rev'n at a stop light...come on, admit it...you over rev'd...leading to spun bearings, loss of oil pressure and a few miles later knockin rods!

either that or your vacuum cleaner turbo leaned your mixture out, heated the cylinders and caused all this mess. Either way, Im thinkin you left out some vital information about how it happened

well yall wont believe this but i think a piston is stuck or sumthing else that is metal. i started my car about to leave, then all of a sudden it just shutoff, thinking the battery maybe crapped out i tried to start it again, it sounds like a piston is stuck or hitting something, i had to leave it at a gas station down the street, its still there now waiting to be towed back to my house.this better not be the 4th engine that crapped out on me, i hope i just need to replace a piston and maybe a port,hope i dont have to replace the block or something major. im starting to hate my supra ever since i got it, it has been a money sucker, gas guzzler, engine crapper. What my mom and i want to do is trade in a van that we have for 2 cars, i wanna get a used civic go safe and save gas!!
