Re: UPDATE! Gas coming out of fuel neck nozzle...
Yes, if you consider all the charcoal canister & fuel vapor stuff as BS.
Gasoline used to take a long time to age, now with the alcohol(or maybe even without) it ages quicker, and venting to atmo might make it even quicker.

Thank You jondee86!! Aftermarket isn't smart enough to include a necessary feature, but they are smart enough to know you aren't going to return it.

Re: UPDATE! Gas coming out of fuel neck nozzle...
The tank's filler neck has a small tube inside it that goes down past the end mounting & turns up into all that space above the entry into the tank, it's a vent. The stock tank, not the poorly soldered aftermarket. When that tube gets fuel in it, like the airlock/p-trap on a kitchen sink,it stop...

Re: Deck plate necessary?
Bore distortion is very pronounced on some blocks, not so significant on others, Any cylinder boring is going to weaken it and higher head bolt torque will increase the effect. EVERY block deforms, its just a question of how much. Does your bore wear look different between the head bolts Vs adjacent...

Re: Cross Plane 4AGE
It's not just regrinding the cam, it's putting the lobes in different places, and a cast iron blank, before factory machining, just doesn't have metal where you'll need it.
Get a sawsall, learn how to weld REAL WELL, cut & paste crank & cam.

Driveshaft in place? Missing clutch disk?
This sounds pretty much impossible to happen otherwise, at least not with out a lotta noise from a clutch disk that's separated from its hub.

Re: .030 Bore on Blue Top.
Be EXTREMELY careful getting those pistons.
I didn't think any machine shop would ever bore a block WITHOUT having a piston in their hands, WAAYY too easy to F it up otherwise. Very bad practice even if they didn't like you.

Re: Flywheel bolts... the lowdown...
Lots'o fretting on all'o them, moving around A LOT before failure. Just too loose/bad install IMO.
Also pretty unevenly on the first one, nothing symmetrical about its wear.
They have to be tightened in STEPS, criss-cross! Also a perfect surface, lapping in might help.

Re: Rear main seal leak? Mysterious loss of oil.
...can it only really leak when the car is under load and other wise it just doesn't or never notice? No. Any leak will get spread all over the underside, except for slow ones that drop off, rather then spread out, when you hit a bump. That seems like a pretty impossible amount to be unnoticeable. ...

Ask friend if it was running those useless ARP head studs that'll restrict oiling.
Polish up the journals and put a nicer radius on their oil ports instead of the sharp chamfer/edge/countersink they've got now.

Re: oil level at idle and at 5000rpm
A little lower then engine off and a little lower still up at 5000. Windage makes it awfully tough to gauge & mostly useless.
Doubt that there's more then a half pint/250cc up top unless G's or tremendous blowby are concerned.

Re: 16v not feeling too great at low speeds.
What's the compression?
Does it miss or surge or feel funny when redlining 2nd & 3rd?
Is the timing adjusted for a smooth fast idle, and octane so it'll only ping/detonate if abused, like trying to accelerate in 3'rd at 2000rpm?

Re: 4age 20v piston to valve question
ALL piston & cam changes should be mocked up!
Then again, if these new pistons are trying to keep it non-interference(NFG, horribly cut up IMO), the even the wildest cam won't come anywhere close in operation & only touch with a belt break or mis-assembled.

Tire pressure, make sure the vacuum advance is working, also ease off the throttle & push into neutral(you don't even have to use the clutch) instead of charging up to a stop light or downshifting double clutching like a jr raceroo to wear the engine & drivetrain instead of the brakes.
