Replacement Engine Question

[xiionn]

My car had a replacement engine put in by porsche in 2009, the car is a 2003. The engine has done roughly 13k miles now. This leads me to a few questions.

The IMS bearing, was this ever upgraded or redesigned, so will a 2009 engine (Albeit not built in 2009 probably) be subject to the potential IMS failure. I only mention this as 13k miles in 4 years is low use and i know for a fact that in the year before i bought it it covered less than 500 miles...so it has been stood periodically. This is the worst scenario for porsche engines with regards to the IMS

Second, is the service intervall on a 2009 engine going to fall in line with the MY2004, or earlier as with the rest of the car?

Third, was there any changes to the motor over its life after 2003??

The motor always seems to run hot, even after a long slow drive at 50 on the lanes, it smells very hot, obviously so as soon as you get out and pings a lot. Was there any change to the cooling system in those intervening years?

Thanks

I also have a replacement engine but from 2011.
I am sure we got the stronger updated bearing, but it can still fail, but the risk is very low.
I dont think the cooling system has been changed...I am sure.
But I have installed a third radiatorkit from design911, and a low temp thermostat, so the coolant dont get so hot.
It is two upgrades that is worth every penny;-))

As far as I know there is a different bearing which all replacement engine have got. The design itself is still the same of course. So you still have an intermediate shaft.

You get the last production revision for that block.

They are not developed after succcesion and are not built to earlier spec, irrespective of your car's age.

You don't have a 996.1 3.4, but for example, this engine still ships as a dual-row bearing.

As that was the spec from in 2001.

Change beyond simple modular ancillary upgrades would require block remachining or new dies.

This is NOT performed.

To get the point: the M96/M97 block still runs IMS any way.
