Ah, great!
How did the leak reduction project go? |
Not very well - have plugged all the do-able leaks.
But still cannot hold a static test pressure. Those leaks are not really fix-able; leaks at the idle screw, butterfly shaft - neither of which are O ring sealed, and at the aluminium Y piece that pushes into the inlet manifold block. I say pushes in, because that is all it is - a piece of Al tube pushed into the manifold. Have tried to seal it - don't know how sucessful yet. The injector blocks are well sealed now. Hopefully I have all the big leaks, but it seems impossible to deal to some of the smaller ones. But it must be better than it was. Will find out soon. In the next week or two, I think I'm actually going to get to drive the thing. Regards Alan |

Did you move/remove the distributor from the engine? |
Dave, not a stupid Q - but I did not remove it. I did remove the clip, and feed , or trigger wire that goes into the base of it.
I have re checked the timing. Goran, the Y piece is an Aluminium tube that sits almost below the BOV - plugged into the intake manifold. I found a bit of a leak coming from there, then found it could move (twist). Looked at it some more, and figured you can't unscrew it - one leg is too long to clear the manifold. So, wiggled it a bit and it came straight out in my hand. I was a bit surprised at this bit of Porsche design - considering it takes up to 14 psi boost pressure as a fitting. I have reinserted with loctite and crossed my fingers it does not blow out under boost - or the car will definitely come to a stop. Regards Alan |
That Y-fitting is frozen in place on my manifold. I tried to remove it when all the smog stuff was yanked and gave up for fear of damaging something. Yours must have worked loose somehow.
|
Brian, I hope mine is now frozen in place too - but want to give the super stud lock stuff time to full strengthen before I attempt yanking on it.
I am surprised Porsche could not come up with a better option - eg a screw down O ring flange or similar. Seems very crude for a part that works under some load. Regards Alan |
