Pinking conclusion??

[Carl Collins]

After all of the recent arguing between some people in here about pinking has anyone made a decision?

Listen to Dave, he's a very intelligent bloke and knows all there is to know about engines! One look at his site will confirm this. It may be basic to look at but its the content that matter - a very interesting read! I'm not pretending i know that much about pinking (i drive a diesel so its a way of life ), but i've never heard the description Steve gave in his post (before all the arueing started).

Indeed. There's a lot of rubbish being talked about the subject but I believe a lot of it boils down to how you define pinking. As far as I'm concerned, it's caused by pockets of fuel combusting early, before the flame front gets there (it's best to think of a spark plug ignition creating a flame front moving in a wave motion rather than the more simple 'explosion' happening in the engine - you don't want it explode!). There can be a number of different reasons for this happening and also different things which sound like pinking. Of course, if you define pinking as something different to this (I always used to get confused with pre- and post-ignition). To me, pinking is a funny thing to call anything anyway and it seems to me like people use it as a rather vague description of 'something rattling in the engine'. Whatever, Dave Baker has been posting on various automotive newsgroups for years now and I've never had reason to call into doubt anything he says - I think I may have had one of my posts called into doubt by him a few years ago and found him to be absolutely correct on the subject... I think it had something to do with optimum gear-change points and torque vs. BHP - a flame war which waged for a long time until Dave posted his definitive conclusions on the subject. If I could afford it, I'd send my XU engine down to him in a flash

Hi Marc,

Sorry, I forgot to reply to your post earlier in the week! Been very busy! Yep, my 305 still drives me to work every day, but it's sounding a little rough and is burning oil! Still keeps going though - might have to change the engine or get it rebuilt soon. One of my friends told me it's time to put the car out of its misery and let it die, but the old girl still has some life yet! I've changed so many parts, it's starting to get newer anyway

Chris.
