I've neglected this thread for a bit... woops.
Friday:
Finally got the 22 block halves apart, there's a bit of scoring on cyl 3, but nothing more than beast had on his 20R when we tore that down at 118,000km's, so not too bad. Put the block halves in "Mr Washy" to see how they come up, hopefully a couple of cycles should do them fine, and I won't have to sent them away.
Saturday:
So, Blighters head gasket issue is a bit odd. I've just been driving him as normal, thinking, 'fuck it, what's the worse that can happen, I cook this temporary motor?' It's only overheated once since the massive overheat last week, up to 98 deg, not even regestering on the needle, so that's fine... But the thing over the week has began to chew more and more fuel, to the point of smelling like it through town like an ol carbie pile... and is starting to drop the revs when warm (used to only do that when cold). The engines def not happy, but whatevs, maybe I'll just tune the link to compensate, dahahaha.
Welp, new exhaust finally going on tomorrow!
Today:
Well, the fuel smell and consumption culprit showed itself... after dropping my work mate home, we were remarking on how fucking strong the petrol smell had become, and it really was down on power today too... so we popped the bonnet, and injector 2 was bubbling fuel out... nice... Even made a lovely pool on the back of the passenger head... Not dangerous at all...
So whipped home and in 30 mins I had the manifold off, and managed to find how it failed...

A quick wiz with some carbie cleaner to get the muck off them, and I picked some new seals of a BG5 manifold sitting in the garage, re-assembled and test drove. Whole thing from key off to key on was just over 2 hours, nice. In time to watch the sun set. Test drove it (partially to listen to my new exhaust too) and it went well, nice to have my power 90% back, but still a bit stally, so the head gasket is still playing up. Because the drive was a bit spirited, temp got to 100 when we parked, and the overflow had boiled over on the way, but the moment you get moving temp just plummets back to 82deg.
And on the new exhaust, got a local mechanic who likes working on sunday mornings (pics up a fair bit of work doing that) to weld up my fujitsubo.

Sounds really fucking cool, just what I was after. Nice and quiet to drive around, but the moment you put any load on the engine, it's got quite a good noise. And WOT delivers an a decentky loud, rough, cackle (gotta love the N/A's for that). Very pleased indeed.
