New to using of turbo engines, im told after driving it your ment to really leave it running for maybe 30secs after use to allow oil to flow, or something im not to sure.
Say i do 5miles and its up to 90c temp, will it cause harm if i just turn the car straight off or is it ment to cool down prior?
Same scenario however doing 50miles...
Does it cause harm driving and just switching straight off...?
I know that turbo timers allow the engine to run a little after its turned off, what is the main uhm purpose of these items?
Any specific ones recommended for Z20LET?
Any details be great,
