Location: Under a car somewhere | Been a very busy boy in between updates
Got a few more things recently, some free very thick heat wrap thanks to a very good freind of mine, new track rod ends, ball joints and wishbone bushes - massive thank you to quick_spider, itg maxogen kit from turley and pg1 starter from muzza, fuel pipe from Jon8oy - toatal lifesaver, also had my headset and cambelt kit turn up so I could really crack on
Stripped down the vvc head, was a little afraid at first but with the guides available by Dave Andrews and some advice from R119 GTA I was reassured and confident to sink my teeth into it
Found the timing on the vvc was messed up, when turning the vvc sycnc shaft so that the marks were aligned one side
The other side was then out  , not much I know, but imbalance isnt going to help anything, evidence that either its supposed rover head gasket job was a poor one, or a monkey attacked it 
Sorted the snapped fuel line with a compression fitting, not what I wanted to do, but it fits great and im confident itll do the job perfectly
Got the head to work, gave it a dam good clean up, opened up the exhaust ports to 39mm to match the Janspeed manifold, then got it on the CNC, measured it for flatness, was near perfect only 0.04mm distorsion accross the whole head surface, gave it a 0.30mm skim to try and compensate for the loss of compression from using the thicker MLS gasket
Exhaust ports
Cleaned all the cam ladder, cams and dis-assembled the vvc mech - found the roller bearings were covered in emusified oil  so I hope theyre not going to rattle, I was surprised how simple the mech actually is considering what it achieves, word of warning - if you do disassemble the mech mark up everything and each peices rotation as the little square sliders will interchange and sit in several different directions but theyll sit funny / loose or tight and id imagine would probably screw up eventualy / quickly
Valaves going back in, had a fight with two of the collets for at least an hour, just did not want to go back in, lets just say im glad the house was empty as the swearing was constant for a good 20 minutes
Head all assembled, complete with all new gaskets and piper bp270 exhaust cam 
Got the head back on, both timing belts fitted, most of the loom plugged in and inlet manifold, throttle body, fuel rail, breather pipes etc. on, in need of the lotus cam cover to tidy things up now, having trouble getting my mitts on one though
Got the sump off, cleaned it out and slapped my baffle in, then filled up the engine with a nice treat - 5w50 fully synthetic - happy days
Wrapped my Janspeed and got that in, was a right cow to wrap how I wanted
Made a alloy spacer washer for my alternator pulley as it had a slightly different offset to my original pulley, got the alternator back on the car, but have magically managed to loose the bottom bolt - clever me 
Modifying my ECU holder tomorrow, then can mount my ecu and plug the remainder of my loom in. Currently having major trouble with my hubs, got one driveshaft out now after giving it some stick in the press at work, when I got the drivers side in the press though had upwards of 35 ton on it and it refused to move  so I heated the whole thing up until what I think was all the bearing grease was smoking, still nothing with over 35 tons of pressure on it - what a swine ! Soon as I sort another hub and a coolant elbow I can hopefully get her started up |
