Picking back up on the 993 Leaf green car… I am back in town in Chicago so time to get the engine assembled for this one. Both of my full time engine builders are flat the F out on other customers cars so I had to step in and get this one done. Feels good to be back at the tool chest doing things for a change.
Block is prepped. Acetone the surface is all done so it is grease free for final assembly.
Sealant laid out and ready. I take an acid brush and dab it out. Those things always lose hairs. Flat rate trick is put a dab of super glue on the base where it goes into the handle. Then crimp it down hard with a pair of pliers. That keeps the hairs tight and they wont come off on the surface. Saves a bit of time.
Sealant applied and smoothed out. Less is more here. You want it to cover but still be translucent. Just a tiny bit of squish when it is bolted together.
Time for sewing class. I am well aware that aircraft procedure is two lines of thread continuous but I only use one. Never had a leak or a failure. We can debate that till the cows come home but we have had incredible results using this methodology.
Slam it home. Key here before you get the journal bolts in is to leave it up on the shuffle pins so that the sealant doesn’t harden. That allows you time to get the bolts all fitted with the o rings while the sealant stays fresh and unhardened.
Final product. Perfect amount of sealant squish (subjective I am sure). But anything leftover on the inside is just washed away and dissolved when you start the engine. The outside is wiped off so it looks like we were never in there.
Tomorrow is deck height, long block assembly, cam thrust and cam timing!
Thanks for following along!
