RMS, again, opinions on engine replacement.


Recommended Posts

Excellent thread on the "Underperforming seal". Lots of info.

My car is going for it's second RMS leak next week. Got the lowdown on the new seal with the plastic installation aid ring from the above thread, as well as the new tool. But, I think they did all that the first time, january 2005, so I'm not so certain it will work. If this leaks again, they may offer me a "new" engine.

How about some opinions? I've got 36K miles on this engine. I'm actually quite happy with it, not a problem other than the RMS leak. The "new" engine, if it's offered, as I understand from previous postings is a re-manufactured one. If offered, would you guys take it?

It seems like a no brainer, TAKE IT. Brand new, I probably would. But re-manufactured? Why was it re-manufactured? Would I be replacing one problem for another, or worse, inheriting a new one top of the RMS?

remanufactured engines are not made from blown up engines

after the engines are built at stuttgart, they are placed on a dyno for a half hour or so

they are required to be within 2-3% of stated output by german law

the ones that don't pass are taken to a separate line where they are adjusted by special techs that we were told can usually tell what the problem is by looking at the dyno chart

MY99-01 replacement engines don't have the AC attached, MY02-04 do. At least, AFAIK.

Thanks for the replies. There have been a lot, or at least what rumor has as a lot, of returned 996 engines. I have visions of these same engines being dismantled, washed and scrubbed, re-assembled, bubble gum and band-aids applied, then sent back out as "re-manufactured" :D.

What are "re-manufactured" engines, anyway? As was said, are they simply new engines, never placed in a car, that were re-tuned after failiing a dyno?

hmm.. another selling point, 2Y warranty on the engine?

Take the new engine, but beware, it is a green engine, and despite advice to the contrary, should be broken in for the first 1-2K miles.

I had the recurring RMS issue, and had a remanufactured engine installed. The advice from Porsche was drive it like I normally do, which I did, and 500 miles later, it threw a rod and cracked the case. So on the next engine, I drove it by the new car regime, keeping the revs under 4000 for the first 2000 miles. This engine has been superb! Don't know if the first engine self-destructing was coincidence or what, but that is what happened to me.

Here is what the new (remanufactured) engines look like. Nice thing is that they get all of the updates from the 2005 996 run.

"remanufactured engines are not made from blown up engines."

So, what are they made from, skylar?

For Gary, dream on....

So, what are you saying? You would NOT take the remanufactured engine if the only problem with the 36K mile one is RMS?

there goes Jeff again, getting people edgy,

We don't call Jeff a tool without good reason! :clapping:

Get a new motor, you will not regret it. Only suggestion is to wait until you have 40K on the chassis, so all of the maintenance requirements will still line up. i.e you will do a break-in oil change at 45K miles, and then you are back on the regular maintenance schedule, except you do the 60K at 100K.

OK! Thanks again for the replies.

40K miles will be about right. Replace RMS at 36K miles, run around several tracks for the next several months. If it leaks again, it will go back to the dealership during winter hibernation before the extended warranty wears out. Then, leisurely break-in during spring the following year. Cool!!
