Oh sure they didn't help too much , did they?
Hard running a cold engine.
Not Good!!!
Aluminum and steel parts expand and contract at different rates. Engines are built with tight fits in some spots and specific gaps in others. When the engine is ice cold, all the parts are smaller but close to these dimensions. When the engine is at running temperture, all these parts expanded to the proper dimensions. It's that in between stage that is extremely taxing on and engine, a transmission and a rear axle.
When you first start a car and are very heavy on the throttle, you are having high temperture explosions going on in a cold cylinder which causes the cylinder to heat up at a faster rate then the rest of the engine, causing the proper gaps and fits to go nuts. This will lead to damage and premature experation of parts. As a do it yourselfer, I don't want to spend the time or the money to fix parts that die because of these failures.
My wife and I even chug down the road until we get to a main drag just so the Bearing grease can warm up and move around before spinning up those wheel bearings to 55 MPH.
I think perhaps a mechanic buddy (the Mrs.) by your side when you are working on the cars might give her a little appretiation that it's not all giggles.
I recall dropping a drive shaft and doing a 'U' joint with my wife under the car this winter....She'll remember the sound of clunking 'U' joints and will tell me BEFORE the shaft has totally let go.
Please Mrs Frustrated Hubby, Give the car a brake. Yes, it's (just) machinery but remember that animals heal, Machinary has to be fixed.
I'd rather get bumped with a car then have a car bump my car.
