Left Rear piston and pin. A couple of minor scratches on the bottom. Circlip came out fairly well, but I'm wondering if I scratched stuff in some way I shouldn't have.

Left Rear Cylinder. View from the bottom. You can see the cross-hatching in the bottom, but it seems to be worn off where the piston was "active"

There's no reason to take the head studs off - they're genaerally good forever. The most important thing I would recommend is to have the galley plugs tapped and plugged. Especially the ones behind the flywheel as well as the 2 up front above the oil filter. After that be sure to remove the oil pressure pistons (bottom front, and possibly on side below cyl #2) and thoroughly flush out the oil galleys, as there will be metal debris. good luck and have fun.

I'm giving it up for the night. I thought I had all the bolts but I am not able to separate the case into halves. I'm either missing a bolt, or the PO used a chit load of sealant/glue to hold the case together.
Any suggestions on splitting the case? |

Yeah, make sure you get all the bolts out. It's just that simple. (IMG:style_emoticons/default/smile.gif)

QUOTE(Cruzing @ Nov 8 2006, 05:51 PM)  I just went through a 2.0 rebuild with a very good porsche mechanic, he warned and I found out that the 2.0 heads are going to be a problem, they do not make new ones anymore so all you get are remanufactured ones, I have gone through 4 heads failing now, valve seats slaping out on the exh. side, I gave up and now installing a 6 cyl... good luck on your project, hope you have better luck than I did... (IMG:style_emoticons/default/smile.gif) This is the weakest arguement for going to a six I have heard. Tell your mechanic that you can order brand new 914 2.0L heads from Porsche (PelicanParts has them) or have them rebuilt by HAM or get brand new CNC 914 2.0L from HAM. No dropped seats as HAM does it differently from how Porsche (VW) installed the seats in the first place. BTW if you were dropping seats its cuz you were running too hot of CHT's as they will fall out at 425F. I would run away from this uninformed mechanic. |
