  1. In this episode I continue the build of my 2.8l engine for my 911 and I fit the cam towers.
  2. This week I pull the Alfarrari back into the shape it is supposed to be.
  3. I was under the impression that the RS and the R's were also effected?
  4. It all comes to a head this week. Or six to be more accurate.
  5. I am not sure. I just know that there are a bunch of explosions that happen when new cars burn. It keeps you on your toes that's for sure
  6. Definitely could be an issue, but the amount of crazy metals and components in cars these days, when they burn it is nasty either way.
  7. To be honest, almost any modern car burns and explodes almost as bad as that. With all of the airbags and other charges in cars these days they pop and bang like crazy. It still scares the sh!t out of me every time though We still put them out, I just make sure I am standing back
  8. I have no idea. I was just at Performance Developments when Neil was going through the development for the fix, which is very elaborate. You need to actually send the heads to them and it involves machining new oil galleries into the heads, and he has designed and produced new finger followers.
  9. I am just going from what I have seen. Neil at Performance Developments has seen a few blown up and had a brand new set of replacement heads on the bench and the oil delivery was all the same. The issue is that the hydraulic finger followers push hard against the cam the whole time, so there is basically no room for the oil to get between. The other big issue, is that basically the oil gets sprayed up onto the lower cam, and the engine just relies on the bottom cam flicking oil up to to upper cam. There is no oiling for the top cam. That is why the first lot of engines particularly, were wearing out in a couple of hundred kms. Adding extra hardening to the parts will make it tougher and last longer, but the design is flawed.
  10. Basically their fix is that they just added more hardening on the cams and followers. That will delay the issue, but doesn't correct the original oiling problem.
  11. True. After would be much worse, as you would probably replace the engine with another which will be as bad as the first, because Porsche's solution for the issue delays the problem it doesn't solve it.
  12. The difference being, that the 991.1 engine issue is not a 'cheap' fix like the IMS bearing of the 996. Performance Developments in the US have a fix, but I believe it is around $USD30k. I wouldn't want to own one of these cars after the 10 years warranty is up that's for sure.
  13. I used Troy Fink who is located in the Wollongong area. Fink Engineering. This week I start designing up the adapter plate for the Ferrari engine and I see if my old Alfa shell is straight or not.
  14. It amazes me that Porsche would do this instead of just making wider wheels to make use of the space they made and making them with the correct offset. Surely there was the case for this and we would have seen so much more lovely dish
  15. This is the easy way to measure valve clearance on an aircooled 911 engine.
