Not yet. Went to the shop after work: Pulled axles, oil pan bolts, then remembered there are those (3) 6mm bolts you can't get to unless you pull the trans, clutch and flywheel so I changed plans to start pulling engine and ran out of time. Makes me want to modify the pan to make those accessible in the future, but I'd like to look at it all apart again first to make sure it could be done (I'm thinking allen head screws?).

I did, however, get 2 sets of Rod bearings sent over. One set of ACL .000" and one set of +.001" in case I'm close and just need a polish. The more I think about it, though the more I just want to tear it all down and clean it all up again.

Since oil pressure is so good, What I'm worried about is maybe 2 things:
1) A bearing was too tight (which I find hard to believe because I really thought I spent my time measuring everything).
2) trash was in an oil galley and I didn't get it all cleaned out on initial assembly. No 1 rod and main would be the first to take trash that was in the main galley so that could be the cause. Sound REALLY sounded like it was coming from the front of the engine.

Low oil pressure would have seemingly affected no. 6 first.

First day - sinking feeling, followed by a pitcher of beer and some pizza...and NO sleep.

Yesterday - Felt real good and progressed quickly until I realized the trans and flywheel have to come off.

Today - Hey man this thing isn't going to fix itself and the oil pan had to come off anyway to be properly welded so we really aren't that far behind yet.

Who knows what tomorrow will bring?

I really think I should order some main bearings real quick just in case it was trash I could swap the front main out. Actually let me do that real quick!

There's nothing worse than something going wrong and you did everything in your power to prevent it from happening. I know that feeling all too well.

But yeah, that much visible metal is not a normal break in. On a magnetic sump plug it's usually quite a bit of metal but once you transfer to a rag its very very fine

Rod bearings are PERFECT. One has a tiny dent or impression of something soft in it. Journals on crank are perfect look brand new. Dare I pull the girdle to check mains?

A few shavings in oil pan look like aluminum

Here's the second "worst". f05be52c9e2e9b2ece32c2157749b13a.jpg

The others literally look brand new.

Few metal shavings in pan are aluminum...like porting aluminum. Like from my diff install. But dang I cleaned the hell out of that thing before having welded and putting diff in!

Every single main bearing, Rod bearings, cam cap, and anything we can see looks literally brand new. There is nothing wrong with this engine that I can see. My brother thinks it had to be some accessory making the sound or maybe something with a valve spring or lifter (in which case putting the oil pan back togethEric makes no difference now. I'm fixing oil pan and going back together with it all this weekend. I can't believe it honestly but dang like I said I have never had a bottom end problem...everything measured out perfect upon assembly.

Harmonic balancer is tight as heck.

Squirters looked good lots of clearance.

Cam gears tight.

Timing belt lined up and tight.

Only things I can think of is some sort of valve spring issue (but sounded too quick for that) or you are right wrist pin or some kind of head contact (again which is totally doubtful imo).

We looked in cylinders. No issue pretty dark from running rich. We will look again for signs of contact

Well I almost had it all back together but couldn't get the trans stabbed by myself so I should have that all done by tomorrow afternoon and we will see if the ghost knock still exists. I did find a bolt in the bottom of the fan shroud. Silly of me not to look there but I would find it hard to belive that where it was it was causing this noise.

    • Have a vb in honour of the car comming back
    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
