JP4 Block on J4 Head.
 

Right, J4 head has two holes on the right hand side of it, where the JP4 has one..

On the J4, the Second hole at the rear seems like some sort of oil way/breather. Am I correct? On the J4 block it seems to have somewhere for the pipe to go, on the JP4, it doesn't seem to have anywhere, this is where I am wrong, where should this pipe go to? How should I go about blocking/making a breather for the oil to return down to? Can I block the hole up without causing any problems?

Please, no noob replies, only reply if you are nearly certain to what the hole does :)

Thanks

Surely someone must know?

??????

try runnin JP4 cam covers mate and get an oil ctach tank and some piping that will sort that out

These ones?



If it is these ones I wouldnt worry about the front one at all..

I have heard so many arguments between peoploe about how this makes your car go faster, load of rubbish

Yes that's the ones, it the rear one that is pushing out Oil and air into the bay.

Are they possible to just seal up? Seeing as the JP4 head doesn't have it, but the J4 Head does.

????????

What the hell am I going to do with this hole?

Is there even a place to relocate it to on the JP4 bottom end?

It's a breather irc on j4s

Jp4 doesn't have one.
I'm not sure how much oil passes through it tho

You can covert to j4

But you will need to drill and fit it into bottom end! Been done before( have pic)

Or run a catch tank if not heavy loaded by oil.

Fuck.
