1j Rod Knock

[JustAnotherVictim]

This IS NOT a 1j bashing thread.
However just reminding people that you can get rod knock or blow head gasket on ANY engine.
Even a 1j or 2j.
Taken from SF.

So me and a buddy of mine (jdmJZA70) were having a little run on the highway with a new mustang GT when all of a sudden, his car stops making power in the high rpm range.

I let off the gas pedal (I was driving), and then the engine shut off and started making this horrible knocking sound that's all too familiar. spun a fucking bearing. We pulled the engine out and stripped it down and here's what we found:

It only happened to the #6 rod bearing. Right after the knocking occured we checked the oil level and it was still at the full mark. Anyone know what could have most likely caused this? Bad oil pump? blockage in the crankshaft oil passage near the #6 rod bearing?

Any suggestions are appreciated.

And your point is???? lol

 

[GotToyota?]

ANY motor can have rod knock, anyone who is oblivious to that is an idiot.

Quiet traitor.... :biglaugh:




We'll just say I had a specific person in mind for this thread...

 

[Brewster]

who would that be?

 

[jdub]

Let me guess...the current 1J/2J zealot running amok on SM?

:runaway:

 

[Doward]

Ha... damn jdub, what makes you think that?

ANY motor can get rod knock.

 

[jdub]

^^^ You got that right...of course mechanical engineering means nothing to these types. And there's a couple of them running around here at present.

I actually like the 1J...it's not for me, but it looks like a good motor. It's big downside is the availability of parts...getting specific things from Toyota is a challenge.

 

[Brewster]

it's really not that hard to get parts for it.

 

[RazoE]

my old 240sx had rod knock; sucked big time...

it was my fault though, 100+ racing my friend's RSX Type S...

Special order from Toyota? Or where? What kind if time frames are we talking about to get parts?

Well what do you need? When my first 1J bit the dust, I was able to have a replacement engine, gasket kit, and odds and ends parts I needed shipped to me just as quick as any other part. Even when I ordered parts overseas. Took just about the same time to reach my door as coming from in the US(except for maybe locally or something...

Any part that normally needs replacing is sourced from other toyota cars easily.


Alternator is a direct fit from a 92 SC300

Starter is a 2jz and or late model 7m Starter.

Mostly I meant a part you need to get the car running ASAP...like suppose you blow a freeze plug and you want to use OEM Toyota, how long does it take to get?

BTW - just out of curiosity, what caused your first 1J to bite the dust?

 

[Big Wang Bandit]

Joe was running too much boost untuned. He wasnt aware. 20+ PSI joe?


Detonation and pop, down goes a 1jz.


A freeze plug? Im not sure what I could get that off of. Probably needed from Japan

freeze plug? idk. depends if it can be sourced from another engine or not. and if not, there's enough 1Js sitting around in the US. I'm sure if you posted a need for it someone would be able to help you out.



nasty boost spikes, detonation and all that fun stuff killed my 1J. It wasn't done on purpose. The ECU I was using didn't have any limiters, so while tuning the boost controller, the engines will quit before mine since there was no fuel cut to save it. I was only trying to aim for ~15-16psi.

With something like that I would call up Champion Toyota and see if they could get one airmailed from Japan. Most common parts that fail are used on other Toyotas or can be found on ebay and the forums.

At the moment everything but my 1JZ is the problem lol.

 

[jdub]

Yeah, detonation will kill ANY motor too. Sorry to hear that Joe.

The reason I asked about freeze plugs is my 7M blew one...I was able to go down to the dealer that day and get it. Car was running the next day. Not a slam on the 1J...like I said, it sure looks like a good motor and a good friend of mine is having Aaron install a 1J in his '89 Supra even as we speak. In fact, I pointed him to the guys at Drift Motion.

So, is there a list some where that cross references parts for other Toyota motors for use on the 1J?

 

[Brewster]

sure is
