You cant name an shame on PH because for legal reasons, no matter how much we want it to happen they have to remove it
So...How do review site get away with it then? I don't believe there are ANY differences in legal/liable rules regading Review sites and Forums?I also see no evidence of a swell of companies, no matter how big, serving litigation notices to such review sites?
Provided the post is factual, expresses personal opinion, and is not abusive, and the site is run with reasonable already established common constraints, then I can see no reason why PH could not run such a service.
Indeed, I would hazard a guess that many PHers would find such an addition to this set of forums as very attractive as it offers a most useful resource to their frequent quests for good service providers, ....and such is bound to swell the readership even more!
Food for thought?

important update on LS376 engine.
before you rush out swapping cams, ecus, trying to map hptuner/efilive a guy trying to build an SLC had the initial symptoms as others but discovered his MAF was in backwards. when turned 180deg it "runs like a dream" (presume by ear)

I ran another crate LS3 from our friends on my engine stand yesterday, guess what......
NO OIL PRESSURE
I have sorted it out (compressed oil seal), i think its very important all these crate engines are checked before being installed in a car. I will not even bother mentioning it to the suppliers as it wont be their fault.

This problem could be easily avoided with two minutes of preparation during assembly, rasor sharp edges on the O ring groove and corresponding hole in the pump seem to be responsible.
Its one of the issues of being a box-moving operation only, very little tech knowledge or hands on availability when a box of goods fails is difficult to resolve economically or quickly... which doesn't help the end user at all. Being as these units are of considerable value (5K+ each) the supplier, if not able to offer proper tech support, should at least carry sufficient indemnity or include sales warranty to enable the end user swift resolve. The supplier are in a difficult position with the end user but the manufacturer are at fault.
Things have not changed much....... a few years back I got a new top line SRi hatch with every option from the same manufacturer. Great looking car, gadgets, trim, everything appeared A1.....after 3500 miles it was knacked....rattles rumbles, electrical faults. They took it back in the end and I vowed never to bother again. Designs are great but production standards do lack.

Well guys and girls after ,much debate, we changed out the ls3 factory fitted - gm parts world supplied cam shaft and replaced it with a standard ls3 cam and a standard ls3 map - Guess what!!!!
Thats right the engine works a treat - idles beautifully, revs great and does an amazing job of sticking to fingers or 8 valves up at a certain supplier in cannock who claims it to be an install issue.
Naming and shaming rules bother me very little however it is extremely important to point out that if anyone buys an engine from a Cannock - staffordshire supplier, please beware!
We have now proven that the cam installed by gm and supplied by a cannock-staffordshire gm supplier is the fault, the supplier will not admit to this fault will not assist in anyway and will continue to sell you an engine that will not run correctly for our application, im sure it will fail in other applications but this as yet is unproven, many fellow kit builders using this engine are kindly sending me lots of feedback from their ventures with the ls3/480 all of which arent good.
Please dont go through the headaches, a standard ls3 with a carefully selected cam will work so much better, but to play it safe map a standard ls3 and see 480hp anyway!
I feel this pretty much signs off the issue! Next step first start again and re book PREP for iva again!!!
thanks for all the comments guys. This was one post i did not want to start.

name and shame can backfire but you can always quote a quote..
""""""""""This is a great plug and play system that works very well as supplied and there is plenty of room for tuning ..so long as the person doing the tuning is switched on....and truly capable....not just a forum or internet jockey ....""""""""""
well done mark... as you know i managed to IVA (after 3 attempts) with a plug and play and piggy back. Once road mapping began tuning this engine was a nightmare.
I am swapping the ECU/piggy back for a stand alone system and keeping the Ls376 cam in for now.
will update hopefully by the end of next week to see if this is the other option for this motor.

finally swapped GM ecu over ro GEMS X25 with DBwire, new engine harness from TMME, CAN bus to dash.

Just reading up on the saga of this engine - sounds like a nightmare install.
So before I go out and buy an LS3, can i just get a couple of things straight, so that i am not assuming anything?!
A standard GM performance parts engine LS376-480 + GM Performance Parts Controller kit 19201327 = all of the problems mentioned above?
Just checking i am not missing anything!
