Oil Starvation on 3.4L Vs 3.6L

[Costa]

Was the oil pickup issue (starvation at high 1g cornering loads) addressed on the later 3.6L motors at the factory?

I am aware of the kit which is available to fix this issue on the 3.4L motors - just curious if the factory has cured the problem on the later motors or not.

Thanks

The later 3.4 liter cars are better than the early ones as they changed the internal baffles. The 3.6 liter cars got additional oil pump capacity and as well the baffles. The 3.6 Powerkit upgrade took this even a little further with a second oil pickup point and a new baffle system. But, Porsche still recommends that if you use racing tires you should by the Porsche MotorSports Kit and install it. (Some engine disassembly is required).

Thanks Loren...

I contacted PMSNA and they want $1360 for the kit including slight machine work to the 4-6 cam cover, not including labor ($5-700 est). It is my understanding, as Loren pointed out above, even the 3.6 requires an oiling upgrade on the 4-6 side.

Since these are also X51 parts, does anyone (Loren??) have the part numbers for the oil pan, scavenging pump(4-6 side) with pickup tube , and the cam cover(4-6) for both 3.4 and 3.6. If I could get the parts for a good price, it might be very do-able as an advanced DIY project.

Loren, which 3.4 have the improved baffle system? Mine is a 9/99 build.

Doug,

My documents don't have a build date or VIN number but from what I can tell it was changed in either late 1998 builds or early 1999 builds. My car is a June 99 build and it has changes.

I'll send you an email with all the 3.6 X51 kit parts. There was also an X51 kit for the 3.4 liter that was not sold in the US. I think I have instructions but may not part numbers for that kit.

Really?!?!?! Anymore info on this? Does Gert have it? Is it legal in the U.S.?

[Loren]

Rob,

I'll send you what I have...

Hopefully, Gert will repsond about availability and legality. I don't think Porsche ever got an engine with this kit on it tested in the US.

Cool to know. What's really weird is that my friend's c4s showed worse starvation issue by the tale of the guage around corners than my 99 did. And yes it drive it equally as hard, but probably harder. Weird. I am although a pretty smooth driver, yet so is he. I am "baffled" pun intended- muhahah
