ALH Clutch Housing Hole - Location & Repair

Since my ALH clutch with 216 injectors + chip now slips starting from the 3rd gear, I wanted to try the method of using brake cleaner in the OT hole. Maybe there's some oil on the friction material? But somehow, I can't find a hole. Could someone please tell me exactly where to find the OT hole on the ALH clutch bell? Or am I just blind ?

Okay, it's actually quite straightforward, but unfortunately I don't have a picture. You look down into the engine compartment, slightly to the left of the starter motor and a bit further towards the firewall. There's a rubber stopper there; it should be easy to spot.

How much torque did you manage to get out of it (approximately)?

According to the dynamometer readings, I have approximately 380 Nm of torque. The time taken to reach a certain speed in 3rd gear at 1460 kg, within the RPM range of 2000-4000, is 4.8 seconds!

What is the best way to apply brake cleaner? Should I keep the clutch pedal pressed down while spraying, or should I constantly depress the pedal? Also, does the engine need to be running (when it's cold), or how?

From 210 to 380 - I wouldn't have expected that.
I have my doubts about the strain on the clutch and transmission. I wouldn't be surprised if your clutch also slips, even without any potential "oil contamination."

Regarding cleaning with brake cleaner: I have no idea if you can reach the clutch from that location. If you remove the plug, you'll see a disc with an "OT" marking (presumably the flywheel?). It might be possible to spray around it – perhaps. It's definitely worth a try, though, because disassembling everything is very time-consuming.

Hello,
I would immediately install a permanent water cooling system there!
To strain a clutch with so much more torque!
Best regards,
Günther

A running engine is a reliable way to set a car on fire...

If a large amount of oil hasn't leaked out, this kind of cleaning won't do anything. If a shaft seal is leaking, you have to disassemble the unit; there's no other way to fix it.
