986 3.2 home engine rebuild

[OldManMo]

Next day we got to work as soon as he came home from school.

Oil squirters go in



Bearings


Things are bit too heavy now so I stepped in. All bearings lubed up and crank on


and back together. A bit of panic at this point as the crank did not spin as freely as I though it would. My son then pointed out what we saw on Jakes video that the carrier must be torqued down first. Good he was paying attention when we watched the DVDs

[OldManMo]

so he then torques the bolts


and once torqued and witnessed it spins sooooo smoothly


next the IMS goes on with new scrapper, bolts, guides, chain and bearing. Again torqued to the right setting and witnessed







Notice above the superfinishing media in the dowel, already been removed. Carrier is now wrapped in plastic film to protect it from dust etc while the next steps are in progress

So will share what we did next soon as need to take photos but they include pressing in a new small end bushing for each con rod, drilling oil hole, honing bush and balancing con rods within 1g of each other. I used an engineering company for this

All pistons are new so piston pin was honed to small end bushing, and pistons were balanced to within 0.4-0.5g of each other.

The next step would be to attach the con rods then drop the carrier into the block. Will post soon I promise

Oh yes forgot to mention that we removed the broken exhaust manifold bolts and tapped in new threads after we sent the heads to be cleaned.



Heads have all new valves, spring, washer, collets, guides, seats etc and will be cut to a three angle profile
