Well, as some of you may know from another thread, I had some more power mods carried out at TDI N on my FD2 recently - basically, higher compression head gasket, port matched cylinder head, fettled RRC inlet manifold (see here: http://www.civinfo.com/forum/fd2/546...hanks-tdi.html
As part of the head strip down, my Toda A3 cams had to be removed. Now, these cams are the second set of A3s I've had - the first were replaced as faulty when it was discovered that some of the lobes were extensively pitted after only 12,000 miles use. Anyway, when this second set were inspected guess what? Yep - signs of premature wear on some of the lobes after only 10,000 miles! In this case, the wear was on different lobes to the first set. Neil checked and double checked, and confirmed that there was absolutely nothing wrong with my engine/head/oilways etc as had been suggested by the importers.
To cut a long story short, initial metallurgical tests on my second set of cams shows that their hardness rating is not as it should be - below that of OEM cams - suggesting poor manufacturing quality. Apparently, Toda has outsourced some of its manufacturing to China and this may have something to do with it...
Obviously, TDI North didn't want to put worn cams back in so Paul has donated me the A3 cams that he had used in his FN2 (completely unmarked after slightly more miles) while he tries to seek redress from the importers. Amazing service again from TDI North and shows just how much they care about their customers
As for Toda, I wouldn't touch their latest A3 cams now with a bargepole. In fact, I wouldn't touch any of their products, especially given their price. I think this goes to show that the old adage 'you get what you pay for'
is complete ball_ocks!!
