Update:
So over the last few weeks I have been sorting out bits for the spare engine (will be used for next season) The plan was to buy something in fairly decent nick and transfer the 421 cams over along with the throttle bodies, tweak the cam timing from how it was originally (was miles off what cat cams recommended to me) and then get the map tweaked to suit.
Firstly I got the new engine off the pallet and loaded it onto the engine stand for inspection. Luckily learning from my mistake the last time I collected an engine and filled the back of the van with oil I checked this one before tipping it upside down and sure enough it was full of oil too! The oil was fairly black so I was a little concerned but once I had the sump off the bores look ok, no crank end float, and the bearings were in good condition.
I am going to be incorporating oil pressure and oil temperature sensors into the new loom so I got my local engineering man to make me up an aluminium boss to be welded into the sump.
The sump was corroded and very coke'd up on the inside so I degreased it as much as possible and my welding chap welded the boss in, I then blasted the sump on the outside and put it through the dishwasher to clean it up good as new
I then removed the rocker cover to paint, this was done by masking up all the bolt heads to stop the bolt seats from being painted. It got etch primered and then sprayed in FF-Racing orange
The block was painted black with VHT and I gave the head a clean up too.
Next up was to assemble the bits together to make sure everything fit okay. The alternator brackets had come back from powder coating so they were fitted but the length of the aux belt meant that once tensioned the alternator touched the underside of the ITB's which it used to do from when it was originally built but as with everything else BTM fixed this by running a slightly shorter belt which dropped the alternator and gave clearance so I did the same with the new brackets.
I then fitted the oil cooler take off and oil pressure tee but unfortunately when the tee is tightened it leaves the sensor hole where the oil filter is so I need to work out a solution for this.
The following day when all the paint had dried it was time to fit the cams and build up the rest of the engine. One of my friends (NorthloopCup) was up near Leeds so very kindly he offered to come along with his Renault timing tools and help me out and also teach me how to fit the cam belt. This went smoothly and I think I would now be able to manage it all on my own in future so massive thanks to Mark for that and all the other help he gives me
Thanks also to Chip and Fred who both offered to come up and do the timing on the engine for me very kind of you to offer!
After this I refit the covers and then fit a new set of spark plugs along with a set of ARP rod bolts. Luckily I realised the torque figures on the rodbolts are in Ib/ft rather than nm as I was going to put them in at 42nm but then read it again and realised!
Then that was it really just a new sump gasket, fit the ITB's and then tension the Aux belt ready to pop it into the the car.
I have now ordered the gripper diff and all being well I am hoping to collect the gearbox from Agency before the xmas break so I can get the box painted and then fitted to the engine ready to go in the car.
All the parts came back from powdercoating so I will start assembling everything together next weekend.
The only thing that I haven't managed to get done to the deadline I set was the shell for welding and painting. I am still working on the setup for the front turrets so this is holding me back as i'm trying to work out the best way forward so the shell won't be going for welding and painting until January which I'm gutted about as I wanted to start the rebuild over xmas but this will still work out okay
Wiring will start in February and when that is done then the car will be ready for shakedown! I make it sound so easy
Thanks as always for reading
