Do yall charge a mobile fee for simple jobs like oil changes or does that steer people away

So my mom's 2007 nissan versa started overheating due to a broken radiator leaking coolant. The car was driven and would overheat and either go into limp mode or stop. I changed the radiator and flushed the coolant. Now the brakes are seized, and the car would rev by itself and go back when idling. I did the glove test to test the head gasket, and I don't think it's the head gasket since the glove didn't inflate. However, smoke comes out of the oil fill and the coolant bubbles in the reservoir. Also, when I press on the brake pedal, which is super spongy, the rpms would increase.

Please help me diagnose the issue with this car.

… what is this? Subaru WRX. Tech said it’s normal, but I’m not convinced.

any ideas on how to fix this?

Clutch Plate Cleaning

Hello,

I stupidly rushed to put my gearbox back together and forgot to clean the pressure plate and flywheel. How bad will it be? Will it 100% slip?

Thanks

Customer already approved and paid for the repair, but once I got in there I realized the old parts are actually still pretty good.

Seems irresponsible to remove perfectly good OEM parts and risk breaking something just to install brand-new aftermarket parts that are probably lower quality anyway.

My thinking is leave the good old parts installed, put the new parts on a shelf in case they ever actually need them, and still mark the repair completed because I prevented unnecessary wear and future damage. I call it preventative non-maintenance.

Am I finally understanding flat rate?

Was walking through a semi truck wrecking yard and spotted this exhaust set up.
