MG ZR: Cams & Maps

[Jonny b]

I have been speaking to my mate today ɑnd he recons, either the the timings out, or the the vvc hasn't been put back in properly! If the head gaskets been done then the head has been totally stripped if ιt has been faced!! They have 2 vanos units, ɑnd if the shafts have not been fitted correctly for the 2 stage cams then they will sort themselves out under normal driving but when the vvc kicks in they are out! Hard to explain through typing words! He said check timings right first! If not then head has to come of ɑnd vvc needs checking, fuel will not make that much of a difference
