This. Until someone comes up with data to prove that an aftermarket bearing (any aftermarket bearing) is more reliable than the factory dual row, I would leave it alone.

Short trips are just not that good for these engines (any engines).

The 10 minute idle warm up is no antidote for short trips either.

(While I am a proponent of warming up the engine before driving away my "warm up" routine consists of lettng the cold engine idle only long enough the secondary air injection pump shuts down and the engine's cold idle speed drops to near its hot idle engine speed. I know from observation this is when the DME switches from open loop mode to closed loop mode and as a result fueling is more precise.)

With my then new 2002 Boxster an oil analysis at 4K miles prompted by curiosity helped by a very nearby truck stop shop with an oil analysis machine on site found the oil contained 7% water. That's nearly one half a quart of water in the oil.

This amount of water in the oil prompted me to monitor -- using an OBD2 code reader/data viewer -- the engine coolant temperature in real time and what I found is even during long trips -- 40 miles, 80 miles, even 150 miles -- at high way speeds in cold (mid-west cold) weather kept the engine coolant temperature low below 190F.

The engine oil got warmer if I spent some time driving in city stop and go conditions but where I lived/drove I seldom encountered these conditions.

As a counter measure what I did was instead of following the factory oil change schedule of 15K miles I elected to change the oil every 5K miles and to change the filter at the same time rather than the 30K miles the factory called for.

Since I could not prevent the oil from accumulating moisture and it was hard in the winter to get the engine and engine oil hot enough to boil the water out I elected to remove the water by removing the oil and replacing the oil with fresh oil.

With the engine now with over 313K miles I think my 5K mile oil/filter services have played a significant role in the engine's longevity.

While the deeper sump might be a benefit if you track the car the deeper sump would be a negative in that this would just increase the amount of oil to get hot.

I might add in this case what you should do is to be sure to show up at the track with fresh oil in the engine. While the engine oil will get hot and hot enough to boil out any water you don't want to subject the engine to track conditions with oil that is in *any* way sub-par even if the sub-par condition is only temporary.

Aw, DAMMIT. Get distracted actually trying to fix my 996, and I miss a perfectly good #triggered thread.

If only the 996 had some system you could use to monitor oil pressure...

AWDGuy

didn't jake mention they tested the unit unplugged?

gnat

That's the anecdote I mentioned.

As I recall it wasn't a planned "test", it just worked out that way and the bearing still looked good after 20 miles with no oil.

My opinion differs a bit. I have a 2001 Cab, and I do EVERYTHING in it. I commute, about 8 miles each direction, I haul inventory in it, I park it in a public garage. I drive it in the snow. A car has to perform as transportation for me to own it. After research, I bought this car with the understanding that it may blow up at some point. Price was right, and I have always wanted a Carrera. It has the LN single row retrofit IMS in it. Anyway, after 15 months, and 14000 miles, including some long road trips, she is still humming along. My mechanic gives everything a once over every oil change, and all is good. So at least for me, the mindset going in is key. I am always prepared for the day I may have to sell her as a roller. In the meantime, I plan to drive it, and have fun!

You park in public garages also? Rookie mistake. Someone told me if you park your 996 in a public garage it's prone to malice and premature ej...donation.

The IMS Solution has became the best selling product of the entire line over the past 18 months. It took 6 years for people to finally understand that simple= better. This year sales have skyrocketed for the Solution, and the others have stayed pretty close to the same, except the classic single row, which is now pretty much kaput. Hardly any distributors order them.

As far as what to use, well..... I'm a bit biased on that one. I know which ones have my DNA, so I stick with them :-)

BTW- If you call those copycat guys, they are going to give you a line about oil hoses failing, or some other BS. They know they are copycats, and haven't developed anything. I actually hold the Patent on one of their technologies. Fact is we've ran IMS Solutions with missing oil hoses on purpose, and I have video proof of it. Further, we have two rally cars running the IMS Solution, and neither of them have ripped off an oil hose. If anything these cars encounter that's significant enough to kill that hose, will also total the damn car.

They grasp at straws trying to find something bad to say about the Solution, and the oil hose BS is all they can come up with.

I'm also on a quest to find my perfect 996 or 997 childhood dream car. I'm taking my time researching and learning everything I can about this generation Carrera. Yes this is a tough crowd but the fact is everyone here is a Porsche enthusiast so we share a common bond (trying to think positive). This will be my daily driver with 10 - 15 mile round trip city commuting. One of the owner of a 996 I test drove said the best way to drive this car in the morning is start it up, take off but do not rev the engine high until the oil pressure gets down to normal operation between 1 and 2. Is this correct? Someone above mention it's bad for the engine to do 5 miles daily commute. Why is this the case and how long should this car be driven daily to keep the longevity?

billh1963

It's bad for any engine to only do short drives on a regular basis and not get warmed up. That true for a Honda or a Porsche. As someone posted earlier it's about the oil warming up enough to burn off contaminants. Oil is the lifeblood of the engine.....it's especially important for the M96 to have clean oil.

I'm sure Jake can explain it far more effectively than I can

Oil pressure between 1-2? I hope you mean at idle once the engine is thoroughly warmed up. Oil viscosity affects this but on the road at 3000 rpm you should see around 4+ BAR

Flat6 Innovations

Short drive cycles keep the engine on cold- start, and just- started fuel too long. This is not good for the cylinders/ pistons/ rings, and also leads to fuel contaminated oil.

Unless an engine can become fully heat soaked, and the oil gets above 200F, for a few minutes at minimum, the impurities will not be burned from the oil. This is true with any car.

The two Porsche independent garages spoken with recommended your Pro product and said to stay away from DOF due to the hose. Guess they were wrong on the hose being an issue. Your Pro product is being installed now.

Flat6 Innovations

I have zero reports of any oil hose failing on an IMS Solution, or for that matter, even the oppositions "DOF".

We have a problem with shops properly educating themselves on these products. They often only want to install the product thats the easiest to be installed, as that nets them the fastest job completion time. This is promoted by the way that most shops pay their employees, from "commission" on jobs. This system promotes haste, and negligence, as a tech might only work a 40 hour week, yet he can get paid for 60+ "labor hours" by getting jobs done faster than the allowable time in the labor guides.

So, the act of having to install an oil hose takes time, which the Tech will bitch about. Don't think that the recommendations that someone receives are what's in the best interest of the car, or the owner.

All too often that damn clock compromises everything. In a real shop, you won't find a clock. No one needs to know what time it is until they are told to go home.

So, that was just general information... In your case the Single Row Pro made sense, but the oil hose should make ZERO difference in the decision of which product to use.
