sr20det redtop rod knock???

[Joey89s13]

ok so i finally got my motor started. and it idle fine.. and then when i revved it it had a knock of some sort ? rod knock?? idk what it is this is my first sr..

also the motor has been sitting for over a year.. i got it from someon who got it from someone else.. it didnt run for either owner.. i got it running.,.

and now this damn knock.. im hoping its not rod knock but idk...most likely it is right?/

lmk please

[Sileighty_85]

rod knock is quite at idle and when rev'd it get louder/faster through the RPM's

Check the oil for gold (brass bearing shavings)

If you got gold, then time for a rebuild

[Joey89s13]

forsure.. yeah i didnt even change the oil in that bitch before i started it.. i was so excited to get it started and way to impatient.. thanks tho.. but the thing is it doesnt knock at all at idle.. but then again i didnt listen that long the motor only ran for like 30 seconds before i turned it off..

any other input people?

thanks again

[Joey89s13]

oh and also to check for gold.. should i drain the oil through a strainer to catch the bits at pieces if there is some

[shiftdrift]

that's up to you, after you do that pull the oil pan and look for metal.

[Joey89s13]

ok and if it doesnt have metal or gold what other possibilities are there to what the knock could be..

[fcdrifter20]

check the oilpan and see if its dented in. maybe pan is dented around the pick up and its not geting enuf oil

[shiftdrift]

you say you haven't changed the oil, meaning it could be low, if it is it could be lifters ticking.

[Ceepo]

Wow, you went wrong from the get go...

1. Pull oil pan off check for chunks of bearings it will look like this if it has a rod knock

2. If it doesnt look like that it could be a possible lifter noise(from sitting so long) and they will need to be bled.

[Joey89s13]

yeah i know i was just hella exited to have sr hahaha..

but thanks that picture really helps... im hoping its not rod knock cuz thats gunna put a dent in my pocket haha..

but thanks again everyone for the input ill let you know what happens

dont turn it back on if it knocked on the way up in the revs its top end if it knocks as you come off the revs and down then bottom end every time you turn it on wat ever is knocking is knocking bits of the inside of your sr!!!

[Joey89s13]

Yah I'm not turning it back on. And the knock is as I go up in Reva and as it comes back down to idle so it is top end?

[Joey89s13]

Wait wait wait it knocks as I go up in Revs. But not at idle or when I start it.

[Sileighty_85]

Wait wait wait it knocks as I go up in Revs. But not at idle

Its a spun rod bearing.

You will not hear the knock at idle only when reving the engine.

[Joey89s13]

*sigh* rebuid here I come. But at least I get to put all brand new parts :)

Worst punctuation ever, fail.

Good attitude, +1. Do it right and use all OEM or better stuff. Good luck

Worst punctuation and ever, fail.

I think you mean:

So what, man. Just because you're not getting lean (?) and being lazy. Just trying to help a guy out. Didn't see any useful comments from you!


I tried to fix it, but it's almost not possible to do that, since I can't even tell what you are trying to say about "lean".

Also, I DO actually apologize ahead of time if English is not your first language.

It certainly seems like you speak English but are just being too lazy to type it correctly and punctuate so that people can actually understand what the hell you said.

[martin_2069]

Mayb lazy but txt type is easy and ill brouden your vocab lean=stoned(high) so 4give me for bein lazy

[Joey89s13]

Lol jspaeth your my hero.

Thanks man.....but it's YOU'RE!!!! Come on!


The reputation of the forum suffers the more times that people post comments and use poor English, poor punctuation, or are just too lazy to type words out.


^^^ It's spelled B-R-O-A-D-E-N. Stop posting please.

[Joey89s13]

I know it's you're.

And lol at "brouden". that sounds like soup.

But to stay on topic.


How much do you think it would cost me to do a full rebuild with quality parts?

[martin_2069]

Dude this aint an english test or skool and y would it suffer all this forum is for is sending and reciving info as long as the info is correct and ppl are helpfull not keen been wannabeeeeee police ppl who care more bout punctuation then cars wat kind of petrol head are you???

....because there is no reason to expect that if someone can't do something as simple as form coherent sentences, that they should be able to do more complex tasks, like build motors or diagnose electrical problems.

Sure there are exceptions, but in general, most of the posts on this forum with terrible grammar are also just terrible posts.

Not going to talk about it any more. Done.

[martin_2069]

Yeah well I'm clearly 1 of them ppl as iv built 2 s13's 1 with an sr conversion, now a R32 and all self tought and I'm sure there are loads more ppl so yeah done!!!

And it'll cost quite a bit 2 rebuild whole engine but if done right u'll have a bullet proof sr!!!!

[Joey89s13]

Ok, so I dropped the oil pan just now. And while it didn't look as bad as the one in the picture above, it did have little
bits of metal and sparkles in it. So it's rod knock. Thanks everyone for the help I'll post pics of the oils pan later, as I am on my iPhone.
