New engine, no oil pressure please help

[SPR1NK]

Take the oil filter off and cut it open to look for bearing material.

You Think its bearings?

I was thinking that it sounded like an injector knock.

 

[laserjock]

Valve train?? Like piston hitting valve maybe? How much oil pressure does it have?

 

[SPR1NK]

40 psi on oil, hasn't gotten to op temp yet so imagine that pressure will go down once it gets hot

Right now I think we are gunna crack injector lines and see if noise changes or goes away

2nd injector line we cracked and the noise went away immediately

Don't fret this. Justin is still one of the top guys for IDI parts and anyone can have something happen. I'd pull the injector and see if somebody can pop test it for you.

Or swap it into another hole and see if the noise follows. I’ve had a dead cylinder quit making noise when there’s no combustion happening. I just like to be cautious and make sure there filter is clean before I run it more, especially with the low oil pressure issues you’ve had.

Tomorrow im going to move it to a different hole and see if the noise follows, just want to make sure that it is the injector, this emgine has given me too much trouble at this point to not be double checking everything lol

When i move the injector if the knock doesnt follow what else could it be?

I know justins stuff is good and sometimes you just get a bad part, im not too worried about that

Next would be to pop the drivers side valve cover and check out the rocker for that hole, make sure the pushrod is seared correctly and everything is moving as it should and oil is getting where it needs.

 

[IDIBRONCO]

seared

He meant seated. It's possible, not very likely, but still possible that it could also be the injector pump itself. This happened to us once at the shop I used to work at. We tried new injectors several times. We even installed another engine. we finally replaced just the injector pump and the knock disappeared. Our pump rebuilder wouldn't say what it was, but he found something.

 

[SPR1NK]

Just moved the injector to a different hole and the rattle followed the injector, so i think the problem is found, now just need a new injector

 

[Thewespaul]

Good. Simple fix, if Justin has a waiting list on injectors you can try soaking it in atf overnight to see if it clears up.

 

[SPR1NK]

We called him yesterday about it an he said he'd send one out today, so I figure it'll probly be Monday when it gets here and then hopefully this engine will be happy and dad can run off and enjoy his new engine

 

[IDIBRONCO]

That would sure be a happy ending to this story.

 

[SPR1NK]

Got the new injector in it today and man she runs nice, i think dad will be off and running pretty good now
