Essential Preventive Maintenance and Basic Performance Mods

[RaceChampion24]

This month I purchased my first Porsche, a 1998 Boxster with 67K miles on it. This forum is a wonderful resource for new Boxster owners. After looking through many threads it appears that basic maintenance includes upgrading the IMS bearing, lower chain tensioner, timing chain guides, and installing an under drive pulley. I am ordering all the parts before pulling the transmission and engine out. Since I will have the engine and transmission removed, are there any other essential preventive maintenance actions I should take?

I am also enrolling in driving school that is specific to performance cars.

You might as well do the RMS (rear main seal - crankshaft) while you are there.

Not so sure about the "under drive pulley"

I would inspect the water pump for broken or cracked blades - replace as needed.

I would inspect all the pulleys and tensioners on the serpentine belt - replace if you find any wobble.

 

Of course new oil and fuel filters. Inspect the coolant tank for cracks or leaks.

Air Oil Separator (AOS) while the engine is out is easier. If racing, deep sump and or sump baffles.

 

Engine and transmission mounts.

 

Alignment afterwards.

Thank you for the help! I will be sure to take a look at my RMS and AOS
