Yep :D
 
LOL @ newbie fear of IMS bearing collapse.

You bought the right car, an early 3.4 with dual row bearing and ferrous coated pistons is the toughest 911 fitted M96 engine (so long as you didn't buy a changeover car).

Biggest risk now at 136k is probably worn out main bearings.

Either a) Do nothing drive it and enjoy, many go to mega miles without a care.

or b) have Hartech fully rebuild it and stick a new bearing in for you with all their other modifications for you peace of mind.

There's not much point in doing anything else as its an old engine with a pile of miles and anything could go wrong at any time. Not much point trying to fix one failure mode when theres hundreds of others equally likely.

When you next change the clutch its considered best practice to inspect the bearing for play and flip the outer seal off so it does not retain old oil.

At 130k on original bearing then leave it alone. You're better off changing oil, checking filter for debri or dropping sump. Purchase a magnetic sump plug, regular oil changes and check levels.

Hi, did you install this detector?
I have heard about one called the Guardian from TechnoLab in the US. Was it that one?
I'm a new owner of a 1998 996 cabriolet. Trying to figure out if my engine is dual or single bearing.
All guidance welcome.
