So I recently did what I thought would be a good tune up for my car since its closing in on a 100k miles and I'm about to make a coast to coast move and I will be driving the mini.
New clutch, 16pct pulley, Detroit tuned bypass valve, rear main seal, oil pan gasket, front end polyurethane bushings from wmw, passenger wheel bearing, updated speakers, window tint, supercharger oil refill, crank sensor O ring replaced. What else is there left I should check once I make my trip?

 

Crank pulley, water pump, tstat/housing, power steering hoses, belt and belt tensioner.

You do the clutch work yourself?

 

I have a 2pct larger crank pulley but that will put me at 18pct which I don't want to run until I get internals updated. I did put a new thermostat in a few weeks ago as well. New serpentine with the underdrive 2 weeks ago as well. I'm saving up for a new sc system just because I want to update to newer tech, how long realistically can i leave the water pump on? What are the signs it's going out? Yes i did the clutch myself.

 

On the waterpump, 70,000 miles and if you are going to do the SC oil, the pump is not that difficult to replace.

 

100K is time for 02 sensors as well. I just did mine along with all that other stuff you mentioned.

 

Verify your power steering lines aren't seeping. What about oil filter housing gasket? While you're in there, at least pull the plugs to make sure they look alright, if not change them.

 

Check rad fan operation in low speed mode. Check PS pump fan as well. Change brake fluid and check pad & rotor thickness.
