Thumb

So possibly an x51 engine, as it would be odd to fit just the pump given the work and cost involved. I will confirm next week when it is on an engine stand.

The engine was changed 20k miles ago. It wasn't originally an x51 car.

Yes, except I won't be keeping this engine in the car as I'm building a new one, and if it is a full x51 engine I won't want to pinch the pump off it.

Winner, does your engine has an X51 part number?

I have just bought an X51 scavenge to fit to mine, cost is eye watering, however there is a potential issue with them.

Are you able to confirm the part number of yours? - It looks like an early original pump (000)

99610798000

or

99610798001

Take a look at this thread, google translate will help.

https://www.pff.de/index.php?thread/2767168-funktion-der-oelpumpe-im-zylinderkopf-996-3-4/&pageNo=2

I have had an OPC tech bench test mine and without fluid, it does run backwards, am going to ask Hartech to check with oil while the engine is out.

Would you be able to confirm if yours actually removes oil from the front of the head or blows as described in the link?

I read that thread via Google translate last night- does seem that the 001’s all ran backwards, if that thread is authoritative.

So the 001 would be perfect for a boxster where the issue would be on the other bank and the pump spins the opposite way?

I managed to sneak in to the office for a while and got the gearbox removed along with the flywheel. Looks like the IMS cover needs attention.








A couple of closeups of the x51 scavenge pump and return line.





I should have it on the engine stand on Monday so I can check the engine number.

You have some parts of an X51 , inlet mainifold should be different .

Ive never done the upgrade but i belive its a pretty expensive one to have done at the time .

Some info here ..

http://www.911uk.com/viewtopic.php?t=60293&postdays=0&postorder=asc&start=0

I also think Dammit has an X51 inlet mainifold which is spare .

Not the exhaust either. My guess is it was put in as a long engine when the original engine failed 20k miles ago. I suspect the person who bought the engine didn't realise it was different. It certainly wasn't mentioned when I bought it.

In the early days, Porsche offered an upgraded oiling package, dubbed M9601, 'Additional Oil Suction System 996' this included the X51 scavenge pump, suction pipe and baffled sump.

Back then, the pump was only circa £500 so not a hugely expensive upgrade. - The kit became quickly NLA, but the individual parts could still be purchased, as they can today, at a hugely inflated price.

I have also seen several early factory replacement engines fitted with just the additional X51 scavenge pump, almost as if Porsche recognised the issue was oil starvation and didn't want the owner to suffer again so the pump was fitted.

One of these could cover off how you have the pump but nothing else from the X51.

Onto the scavenge pump, I was planning on giving you guys the heads up on this once I had further info but as you have found a pump now is a good a time as any.

Your Scavenge is an early original pump, (000) part number, it looks different from the now available (001).

I do not know why Porsche changed the part and updated the part number, or when it happened, currently trying to get info out of Porsche.

The German pump where the issue was found was manufactured in week 30, 2007, serial number N35 in France by Pierburg.

The pump I bought from my OPC was also manufactured week 30, 2007, serial number N53, again by Pierburg.

So these would be the same batch and manufactured circa 6 years after the 3.4 X51 ceased production.

Whether the revised pump runs backwards at this point I do not know for sure, but its a concern

It was only found as the chap in Germany had a leak following his install, if he had not had a leak he would not have checked and as oppose to running with an additional scavenge improving the oiling, he would have been running with one less than standard! - Assuming that there is an issue.

If any of these pumps have been replaced/installed how would you check operation? You would assume that its a Porsche part and that everything was ok, fit and forget.

As mentioned I had a Porsche tech, at the OPC check my pump and he thinks that its running backwards, so will blow oil as oppose to suck oil.

I will/have asked Grant to check with oil to confirm.

If it is running backwards, there is only one other additional scavenge available, its an aftermarket setup by a company called TTP in Germany, its fundamentally two piggy backed standard scavenge pumps.

However getting any info from TTP has proven very difficult!!

Would be very interested to see if your early pump runs correctly. - I am finding it difficult to believe that Porsche developed a product to fix a specific issue that they were very aware of only for said product not to work! - But this is how it is looking.

If anyones interested I have the factory install manual for a 3.4 X51, it details all of the changes, I also have the factory parts list.
