Engine re-build progress

The bottom end is now completely rebuilt, with new piston ring! and in the engine is now back in the car and on the later front cross member with the round engine mounts (that are easier to get new ones for)               The flywheel is now on with new ARP bolts from Risse motorsport in germany. (just a note that the ARP bolts are all the same size so you will need to have the locating one turned down a fraction to fit) The new clutch has been fitted again with high tensile cap…

After a slight mishap, where i buggered up the bottom oil control ring on the new piston 🙁 which has set me back £50 and two weeks while i found a new set of rings! the bottom part of the engine is now in the car 🙂 Jan at http://www.zymo-tech.de/ found me a new set of rings in super quick time and they arrived on tuesday (my day off) and the sun was out.

Fuel lines

Having decided that this time i would use something better for the fuel lines as im running injection on the car, i decided on Goodridge hardline with bulk head fittings. I was originally going to run them through the inside of the car and not underneath to keep the underneath nice and clean. But Alf did point out that if a line did fracture i could be sat i the car with a lot of fuel flooding in! so i did a quick google and read up on what other people had done, and it does seem that ruel lines inside…
