/New-to-Me Engine, what's missing

[Goach2]

Before the engine was rebuilt, I cleaned and painted all the engine tin and seals, replaced all the fuel lines (yes, even the evap system), cleaned out the tank and replaced the injectors.

What's a 'wideband'?

Check every FI part individually.
Look up the part number to be sure it's the right part.
Numbers and test procedures are both in the Bentley.

If you're going to use your 50-year-old wiring harness it better be a good one.
There are also procedures for leak-testing all of the components for air leaks caused by wear and old age.
Search 'smoke machine'..
This is beyond the scope of the Bentley because these things were new and/or available new.
Like the S-Boot, TB bushings, dipstick boot and.. On and on.

I like my Innovate wideband.
There are cheaper ones.
Often you can borrow or rent one just to get tuned.

Ever hear some dummy say something like "so easy to work on"
"Motor comes out with only four bolts"
"simple and basic"
They have no clue... Today, you have to pay your dues.

What’s That Noise?!?

[Goach2]

Not much of the FI system was on the motor when I bought it, so most of it (and all the rubber components) are brand new. I will have to look into the leak test.

The bus runs well and doesn't smoke. When it starts, it typically stalls once right away, then can start and will run fine. It's the fuel economy that seems to be off the most. If I recall correctly, I may not have changed out the cold-start injector. Could these symptoms be related to that?

Also, I believe I have to change my brake master as there's leakage there. when I pump the brakes, sometimes I can almost stall it out.

The fuel/air gauge sounds like a good investment, for any vehicle.

So, I was hoping to get a little help from the builder, but with the pandemic, it looks like I'm going to have to tackle the engine tuning myself

Since it's rebuild, it's had a pretty steady leak. I know everyone says they all leak, but I was hoping that this particular leak might be something that I can take care of. Here are some pics, from underneath, closer to the driver's side:

I took these a while ago, so if more reference is needed, I will take some more.

A common source of oil leak is from a bad temperature switch.
They may seal well at the threads, but oil will spray out around the electrical connection.

Cross your fingers this is the source of your leak.
If so, it's a cheap and easy fix.

As for your question about the CSV, it only sprays for a couple seconds when you first crank the cold engine.

Clatter is right about the tuning. It’s not hard to get it Togo down the road. And it will seem like it runs “well enough”. But often it can run a lot better and a better tune plays a big part in engine longevity.

It's a little buried presently, but perhaps this weekend I can get it out and do some troubleshooting.

Pumping the brakes for sure can stall it out, but I believe holding the pedal down allows the RPMs to rise back up again.

For vacuum leak, do I just start pulling hoses off, one at a time, to see if any do not affect the idle? Are there any in particular I should pay attention to?

I will check the temperature switch for leaks and clean up the oil to see where the fresh stuff leaks out of.

After the engine was rebuilt, it was just dropped back (or lifted) into the bay and driven up onto the trailer for the trip home. No other adjustments have been made... yet.

I would get rid of that oil pump and put in an original. I had the same pump you have and got an original from mofoco in Wisconsin no more leaks.

Thanks crownline, I'll add that to the list for the next time the engine is out.

Nice, I like the idea of the old paint sprayer, and I have one of those laying around!

Going to attempt a full tune-up for the first time. I was thinking about picking up something like this:

It's older, but has everything I could need. Will this be sufficient?

Tune-up step 1 complete, adjusted the valves tonight. Most were tight, so much needed adjustment and I'm curious to see how it improves performance (tomorrow). Nice and clean inside:

Also, how do not crimp/bend such a thin gauge?

Next, warm up, oil/filter change and basket clean out.

One would usually use a 0.006" steel feeler gauge to adjust the valves. Brass feeler gauge are included in some sets for adjusting the clearances for magnetic pickups and such.

Remember if you take the taco plate off when you put it back on Only tourque it to 9 ft lbs.
As clean as those heads look I would leave it alone.

This is the first oil change after a complete rebuild, shouldn't the screen be checked for filings?

You can check. I think the filter will catch anything. Just be sure to not over tighten that when putting it back on.
