my oil light stays on for about a second after i start it up cold and i hear a bearing knocking sound for about a second as well during startup. engine is jdm gsr, is this normal? my sohc didn't do it, but i know the oiling system is different on the dohc.

 

that sound you're hearing is called piston slap, its not your bearings i dont think dude

look up piston slap, it sounds more like what is happening. the oil light makes me wonder a bit, but its still worth looking into

 

as long as it goes away, then whats the probleme.

If u have the engine warm, then shut it off and start it again, does it do it?

Or does it just happen on cold starts?

If its just when its cold, then its fine.

 

89s1, i think you are correct, i think it is slap. i had that with my built y7 that had JE's...esp in the winter.

the oil light stays on for maybe half a second, like, literally... i think it's normal.

it just does the sound on cold starts, and when it's cold out. it does it for a quick maybe 4 taps in succession, really fast and that's it.

if i start it in the morn and the sun has been on the car, it doesn't seem like it does it. it doesn't make a peep at any other time, not while revving, not while driving, not if i stop then start it again....sounds like a sewing machine!

 

yeah im in canada where we really know our cold starts

being from jersey you likely see your fair share of nasty white stuff and cold though too

Edit: I also took a look at ur d-series that you have for sale... sick powerplant dude, to put it in perspective i got 154/109 out of my b16 :D so thats one strong single cammer

thanks man!

what's everyone else think of this??? i am not worried about it at this point, but i'm curious if anyone else has heard it before. FTR i am running Castrol 5w30 GTX as the initial oil then i'll switch to my normal synthetic.
