Oil Clouds And Pag Mod?

[WolfgangK]

Hi folks,

in german 911 boards there are some discussions about the race-track readyness of the 996.

One owner experienced the following problem: while driving with high lateral g-forces suddenly there were huge oil-clouds coming from the exhaust and the cockpit lamps went red.

The mechanic said this was due to a lot of oil in the exhaust system which fouled the Lambda probes.

The dealer told him that there is a new kit available now from PAG with a new hose-routing from the oil-separator to avoid this problem.

Since I want to take my car to the track next week I am a bit worried now...

Did anybody experience a similar problem? Is anybody aware of this modification?

Thanks and regards

Wolfgang

I have not heard of this kit being sold separately -- but it may be very new. My guess is that it is the oil pan parts from the X51 kit. This would include dual chamber pump an additional pickup line and two new oil partitions (to keep the oil from pulling away from the pickup during hard cornering).

I am in the process of reading all the posts to this forum and just found this question (I am new to the forum).

I have heard of (never whitnessed myself) of 996's with blown engines on trackdays with Porsche Club Sweden. Symptom was described as a lot of smoke. The engine had to be replaced.

As I am using Michelin Pilot Sport Cup tyres as of this year, I contacted the Tech Support in Sweden and got the recommendation to fit the oil pan from the Carrera Power Kit.

No big deal, something like 170 Euro for the part. As I hade the car in for 60000 km service I had the workshop to do the assembly. The modification is a few extra rubber flaps to keep the oil in the lowest point.

The explanation I got was that in high lateral forces the oil would be "pressed" up in the engine (hence the smoke coming out of the exhaust) and leaving not enough oil for the pump to cool/lube the engine.

The answer is to late for your track day, but I thoght the information could be useful for others.

Hi Anders,

the problem with the smoke is depending on the model year. Early 2002 the 3.6l machines got a longer oil dip stick, a reprogramed electronic oil check and around 1l less oil in the engine. This avoids that excessive oil is fouling the Lambda probes.

Since my 11/2001 car got a new engine due to the RMS problem, mine is now based on the new standards and I did not face this problem.

I heard of several cases where this 'blue smoke' appeared due to high lateral forces, but I haven't heard that engines had to be replaced. The worst case were two new Lambda probes.

My dealer recommended NOT to fill up the to the upper limit, but have it filled in the middle between low and high.
