It's like that on the DML too and I personally have adopted the attitude that unless I'm 100% sure of something, I tend to make suggestions. Only recently on the DML one well-known poster stated that you could tell if the cylinder liners had been lifted by "eyeballing them" - a movement of less than half a millimetre can wreck the gasket. Anyway, One thing's for sure, e-mails are all too easily misinterpreted because they cannot convey tone, body language etc.
It has been mentioned to me on several occasions recently, that some members will not now send posting because of "instant EXPERT" criticism waiting to pounce!
Often the lower control arms are bent due to the car having been tied down by them at some point - lots of trailers are set up to use this method and I have had to tell an AA bloke this before now. I spent some time straitening one of mine on my project car - luckily it wasn't bad. And FWIW got painted with Hammerite afterwards <grin>As you say Martin, none of us knows everything, I certainly don't, but I've jacked up hundreds of cars over the years and have seen the damage at first hand to numerous DeLorean's where the jack was "just put under the front", (or back) catching suspension wishbones, bending metal and cracking paint.
