BPV / BOV repair w/pics

[djdawson2]

'Course I added pics because I learned early on how much you all love them.

The clicking noise... so you all correctly advised me that the source was likely the seals on the BPV. Looking at someone's post, I decided to give it a shot today.

#1... just getting started.
#2... removed the intercooler, couldn't be easier.
#3... upon closer inspection, I decide I'm going to remove the part of the intake manifold that houses the BPV, as it look substantially easier than working in such a tight space on those covers. So I've first removed the air filter housing (3 bolts and a couple of hoses... a bit tight but fairly easy)
#4... the part of the IM that I want to remove has a couple of hoses attached, as well as being a mounting point for several electrical components. All in all, another easy removal, with only 2 long bolts on the DS and one stud on the PS holding it down. It is now out...
#5... the piece of the IM on the floor... much easier to work on!
#6... I've removed the rear cover (closest to the coil when in the car). A couple of taps with a rubber hammer and it came out easily. Clearly, the seal is slightly out of spec... ha.
#7... This is the "front" cover's seal. Interesting that they use the same part, however, in this cover, the seal simply acts as a gasket. For this reason, I don't imagine this one would ever really fail... as nothing is repeatedly hammering into it, as is the case at the rear. I replace it anyway, despite the high cost of the part ($2.50 I think?)
#8... These are the 3 parts of the BPV. The hollow sleeve sits inside the front cover, the spring in the middle, and the piston in the rear. The piston is what moves.
#9... so... while in there I observe this little sweetheart. I'm guessing this is the air pump??
#10... as you can see, the belt is a tad loose... I adjust it, but find myself wondering if I can remove this entire setup? Bueller?

That's it. All told, it took about 2 1/2 hours start to finish, and I was just fumbling along, as this was my very first trip in the engine compartment of an air cooled Porsche. I messed with plenty of loose hoses, and adjusted the air pump belt. I figure this could easily be done in 1 1/2 hours.

Adios, Dave

DJ: Great write up...sure with I had this when I sent the car into the indy because I couldn't trace down the click-click when I tapped the accelerator....looks like a rather simple fix once you know what you're going after.

Kudos to you for the nice write up and sequential pictures. The pics are even in focus!! This is a question I've seen posted a number of times...so I'm saving off your discussion thread as a reference.
