I saw that the block had been pressure tested, correct? If so was the manifold included in the test? If not and as you stated things did look good so we can assume it was running fine before. A pin...

BonChance, the manifold end looks pretty poor. The end will need to be filed or machined flat for a good exhaust seal for safety reasons. Per Jim a good deal of patience MAY break the studs loose as...

A std oil pressure gage and a cheap one is just fine. Just like the fuel pressure gages only for higher pressure. You can mount a tee at the "sender port" or the aft port near the oil pressure...

Ando, I'd try a mechanical gage to confirm the electric. Oil pressure would be somewhat constant and not just drop off as you state, perhaps a sender or wiring glitch.

The wire from the coil to the cap. Remember to turn the key OFF in between cranking so you don't "fry" the coil.

The vinegar is a much less caustic acid and does not attack the iron and steel nearly as much as the "acid wash" does. The "acid" will remove some block material while attacking the KRAP in the...

If you have room just add enough line to create a 360* loop with a bit more line OR change the angler of the fitting or the fitting itself.

A pic of the setup would be good.

Perhaps try a vinegar soak first, very easy and letting it set for a couple of days can work wonders in many cases. I suggest this since you replaced the head gasket and cleaned the cylinder walls...

Question Curious indeed

Jerry, good eye!!! Looks like a spam can covered with insulation of some sort. Possibly a "boxed isolated air intake" or an air filter.

Don can you let us know what it is?

I doubt the ethanol content is different. A water separator is quite necessary today due to the ethanol absorbing moisture and contaminating the fuel. Well the condensation in the tank from the warm...

Leaving the key on is leaving the power on to the ignition and it will drain the battery completely. The other downside is that you probably now also have a fried the (dead) coil. When you get some...

Bill, what do you see? I see a clamp almost off the end of the hose and the throttle arm rubs the fuel line, not real good.

In the video are you going from forward to reverse? Or are you just moving the shifter around in the "neutral zone"? I ask this as I see the detent for forward is not engaging.

What John says is good info. Neutral in the direct drive is rather illusive and the adjustments will fix it. First try moving the trans lever back and forth lightly to see if the shaft slows and...

When in neutral you should be able to spin the shaft by hand but not in forward or in reverse when pressure is being applied to the band.

When the engine is idling in neutral it will also spin if...

Lightbulb FYI
