I read the build sheet today, turns out the case wasn't line bored after all and the crank was polished not cut. Thank God! #1 & 2 rod bearings are gone but the crank might polish out, will post pixs soon. Wont know till I have them checked out. Seem like the Aero Shell oil gave good protection. Could of been worst.

Question about your oil return line routing on the turbo. Where do those 2 lines plumb into?
Would it be the same set-up on my 1989 911?

Main oil plumbing is the same as a 911, but the plumbing for the turbo goes to a pump then to the tank. Pump is on the front of left cam housing.

Yes.

The other line u refer to is actually a vent from the turbo catch tank which looks like it plugs into the cam chain cover. Correct me if i'm wrong Che.

Justin actually it goes into the air cleaner. It's a left over for the smog visual in California. Venting into the chain cover would probably be better. racinjason302 not any more, motor is torn down and the case is split. The tank for a Turbo car has an extra fitting for the line coming from pump on the left bank.Hey Justin how's your 934 running, hope the weather is good so you can take her out for a run. Man I need a Turbooo fix

Doood, 4 hour drive yesterday to see the parental units. No time schedule, so took cop-free twisty back roads all the way. Nothing but Zork/BOV/WG and F6 nirvana. Highlights included destroying an M5 who wanted to play chase coming off an exit ramp and thumbs up from an older 996 driver. This car rocks. Hope u get yours back on the road soon brother, u must be in Turbo DT's' by now!

what do u think caused those bearing to go dry? Was your oil pressure ever in doubt? Any debris in those oiling passages? That crank doesnt look too bad... send it to Walt or EBS and they should be able to work some magic.

Justin this is the mystery, oil pressure has always been good. Only thing I can think of,are cold start ups during the winter. I did find some dirt and sand particles inside the case. The complete oil system & coolers are going to need to be cleaned. Case will have to have the plugs in the oil galleys removed.Maybe I'll just find a 3.3 and put in her.

Mybe someone could decode these numbers, for me? thanks:
I believe it to be one of what later became the IA HF. They added a larger compressor wheel with a smallish hot side. I think it was built back in 2002.

Check with RarlyL8. Someone else posted a pic of he same turbo not long ago.

If it is like the one I had it comes in early, builds kind of softly and more like a V8 than a turbo.

Turboo934 -

Sorry to hear about this.

When mine spun a bearing (or 2), I remember Steve Weiner asking which one spun. Of course I don't remember now, but one bearing means trash in the oil system and another one means low oil pressure. He can tell you. I only mention it because mine was due to trash in the system, so I added an additional oil filter - so as to never have a repeat.

Also, you might want to talk with Armando over at CCW on your options for the crank. He can probably fix what you have, and may suggest 2" nascar bearings, if you're grinding yours down.

Good luck!

Glenn

#5 rod would need a #2 cut an they don't make a bearing for #2 cut.The rods can be rebuilt , new crank is a standard- standard, I hope. The machine shop will check it out before I pay for it. A new one is $7K now, man I remember when Andial charged $10K for a hot rod rebuild. With factory race parts.
