The tube that goes from the middle of the intake manifold to the back of the block, what is this line? Is there suppose to be oil in this line? The one on the right goes into the fuel pressure regulator.

TIA

 

the one that goes into the FPR is a vacuum line I think. Not sure what the other line is you are talking about.

 

OK here are some pics. Hopefully I'll get a definitive answer with these..


Here are the two ports..You can see on the far right is the MBC and on the left T'd into the black hose to the middle port of the manifold.


As you can see, the one on the right goes into the FPR, the middle black one goes down into the block...


Here it is going into the block..


on the left next to the injector..


and on the top neext to the injector..


Someone must know!!

THX!!! At last that clears it up! Now I know why I'm getting oil in the MBC!!

 

You need an oil catch can then.....

 

Where/how would I hook this up to?

 

Pull that hose out of the intake manifold. Lead it to the inlet of the catch can. The outlet of the catch can should then be connected to the intake manifold...

 

Simple as that huh. OK, I'll give it a try. I just have to find myself a decent catch can now.
