I am a newbie, so be gentle !
Just bought an 2003, Mk1 Focus ST170 silvertop engine for a complete overhaul and rebuild (115,000 on the clock), to go into my kitcar.
Spent a very happy weekend stripping it down and all looks to be in good shape.... however, I have just removed the pistons and conrods and noticed that cylinder no. 1 has a slightly curved conrod, which is approx 2.5mm shorter than the other 3.
I noticed that at TDC, cylinder no. 1 did not rise as far as no. 4, and the shorter curved conrod would certainly explain that.
Can anyone explain what this is all about, why is it curved and shorter than the others ?
.... OR have I got a very dodgy conrod ???
