blu260z Posted April 19, 2018 Posted April 19, 2018 Hi guys, can anyone tell me the thickness of an E88 head? My head measures 107.5mm and has just had a fresh decking on both sides just trying to see if it will need cam tower shims. Cheers Quote
Mike260LW Posted April 20, 2018 Posted April 20, 2018 107.9mm I think is the original dimension. Quote
blu260z Posted April 21, 2018 Author Posted April 21, 2018 Thanks Mike. If it is in fact 107.9mm is it worth shimming the 0.4mm (15 thou) to get it back to factory height ? Quote
RLY240 Posted April 21, 2018 Posted April 21, 2018 I would vote no. If you shim the cam towers then you also have to change the lash pads to correct the wipe pattern on the rockers. There should be enough room in the tensioner to take up the extra slack in the chain and there’s usually three options on the cam sprocket to let you advance it to get your timing back. Quote
blu260z Posted April 21, 2018 Author Posted April 21, 2018 Awesome I will also be putting on all new timing gear. Hopefully it should be back on hole 1. Quote
