Re: OEM Upgrade Horn for AE86?

All the above. Yours might only need some tuning. clean its terminals, clean ground if it's 1-wire, clean its relay terminals & contacts, adjust it. That adjustment screw on it, self tapping or threaded& locknut, will change it quite a bit until there's no sound at all at either end of its r...

Re: OST-068: Smok'n

OK.
I'd think that big aluminum ridge around the seat would do more then a bit, but I've got 0 flowbench experience and can only go by what looks aerodynamically pretty to my eye.
Thanks.

Re: Big port overheat problem

Water pump failure is extremely rare, I've never seen one but I've heard of Many water pumps being replaced for reasons only slightly related to it. Not that water pumps don't fail, they leak & their bearing goes bad, but failing to actually pump is almost unheard of, a few have broken impellers...

Re: OST-068: Smok'n

Thanks, looks nice & clean,
Looking at those 3 valves through the intake is always a neat thrill!
Were the other cyls clean & dry & smegma free?

Is there going to be any more finishing/grinding the comb chamber, all the area after the 45, on the 60 to 90 and the ridge around the seat?

Wow, that's a new one!
If the guide's top isn't normally submerged, extra seal or no seal shouldn't oil it up that much, besides it's only 1 exhaust & isn't going to affect the other or the chamber.

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.

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.

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.

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.

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.

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.
