So finally the parts arrived to finish the timing chains, I installed new oil squirters then proceeded to install the timing chains, when I removed all the guides from the old engine stripping it down I could have swore the guides were alloy with plastic coatings, turns out they are all rubber and just gone very hard and turned to plastic along with the two bushes holding the plastic guide on the right of pic two...
Moving along, the head gasket rings sat pretty close to the bore in places i had to file some of the gasket off at the locators on top of the block to get it to sit just right as the pistons come just above deck and didnt want any interference.
I still can't get over how big the ports are on these heads, it's making me think about the exhaust mani that I've got, I'm going to have to do some serious die grinding to match ports
Cylinder head torqued 35nm 70nm then 105nm
Rolled the engine over then went to look at the oil pump then remembered that the pump I is probably in a bad way, I pulled it apart and found very bad scoring and pitting all through it, so went though our stock and found a m52 pump that had a pump wheel, I then found to mount it I had to slot the rear bolt hole about 4mm inwards, also swapped the spring and sleeve from the m3 pump into the m52 so the insides remain the same sort of, I swapped the sprockets over and tig welded the nut to the sprocket and to the shaft, job done
On the top part of the cylinder head applyed some lock tight red sealant replacing the o-rings in between then proceeded to install the cams then I remembered someone saying I have to run a cam trigger wheel on one cam and didn't get any trigger wheels from vac motorsports, they are really expensive so figured I try make one, as there is a 2mm spacer with spline that goes on the end of the cam shafts between the sprocket plates I figure that seens as there is 2mm I can reduce the spacer to 1mm and then cut one of the trigger wheels 1mm from the mating face then I get my 2mm and everything will line up apart from my cam sensor, the trigger will sit 1mm closer inwards to the head as it used to sit after the spacer, I may be able to space out the sensor with a washer time will tell.
Last photo I just sat the covers on, sh*t these engines are cool ?
