Issues with my r33 skyline

[krishyy7]

Hi guys need a huge help from you guys identify  a issue with my skyline r33 series 2

My issue is

My spark plug keeps getting fouled 

Car starts idling  and misfires  but when I put new plugs in it's alright for a day

I just installed new standard block  and head 

I have attached  a video of how it idles now 

Any help will be appreciated thanks in advance guys!

So, either the rings haven't been bedded in and it is burning oil, or it is running pig rich.

The block and head is new just got put in last week

As per your first post. That's not new info.

Also it's a weird thing to say. I think you mean to say the bottom end is rebuilt? It's not a new block is it?

 

Plugs foul by either runing rich,  burning oil or less likely too cold heat range.

Also to add to that your breather setup is wrong and atmo blow off valve with maf sensor is not good. Both will  draw in umeterd air at idle but that makes it run lean, so not really related to the fouling problem.

 

What injectors are you using? Did you happen to change them or other stuff when the new engine went in?

Yes, hence why I suggested that the rings were not bedded in properly. There is a procedure to make a new engine work properly. If you do not follow it, you will glaze the bores and you can forget about it every being any good after that.

Are you asking what the procedure is?

Is not the next thing to just type in to google - "ring bedding procedure" ?

No mate, I'm not going to type out info that is all over the place, but I will say your options are either factory style breather system (with oil seperotir if you like) or completely open to atmosphere. It can't be open on rocker and still be connected to pcv.

 

Bcpr6es for plugs. What are you using?
