How i USE a engine in Gmod????

Hello,

I’ve build a engine in Garrys Mod (with tutorial).
But how i use the engine?
How do I build the engine in a car?

I Don’t find any Tutorial on Youtube.
Please Help me…

-Snip didnt read-

spawn a phx plate… apply 4 wheels on it
weld the engine to the plate and connect the rotating parts of the engine with Advanced ballsocket (settings everything to 0 but minX minY minZ to -0.01 and maxy maxy maxz to 0.01)

!the rotating parts have to be the same direction as the engine!
