Final Stage of a Forged 4G15 MIVEC Build - 1005A886 & MD372536 & MN119379

Its been a long road but we are back at it!
Head has been modified & bolted down with the OEM MLS head gasket.

We didn't use any copper gasket spray as previously planned.
Head studs were torqued to 50NM, released and re-torqued to 85ftlb (3 step process).

We installed the studs dry into the block, we bottomed out all studs but the ones in the doles?
For some reason these holes were too deep and wouldn't allow for enough thread engagement on the nut, so we backed them off by one turn.
I may go back and release the studs and torque them once more.

Cam seal install & cam gears
Grey RTV to seal the end cam caps
Re-using seal, grey RTV to be double sure.
Powder coated rocker cover, it really cleans up the engine
<- Timing belt installation tools, setting timing marks TDC
OK! so after installing everything i forgot to install the steel brackets that support the upper half of the timing cover. So i pulled the MIVEC cam forward so i can fit the M10 and properly mount the bracket.
It wasn't needed, but I wanted to do it right.
We decided to remove the aircon, it weighed 8kg. It makes the engine bay so much cleaner. Extra room to fit the motor
