Brian - Ben is actually the son of a neighbor. He loves old cars and started helping me work on them when he was 10. We probably want to wait on any article until we see how the second part of the drive goes lol!

Day 2. 8 July 2021
Arrived safely in Concord, NC about 2:30 pm. 135 miles. Lots of rain but no car issues other than wipers sluggish at times. Dont know if it is the wiper motor or boost pump. Both have been replaced but the wiper motor was several years ago. No matter will troubleshoot after we get home.
Toured the Mustang Museum, pretty nice.
More pics to follow later tonite.

Day 1 Final
We got into Roxbury NC a little after 6 pm after a run of over 200 miles this afternoon. Total mileage for the day about 320 miles. Route was MD 28 to US 15 South, following all the way to intersection US 360 South at Wylliesville VA, following that to US 501 and into Roxboro. The car ran perfectly. Considering how hot it was today I was worried but nary a hiccup.
Tomorrow will be a run thru the remains of the storm into Concord.

Brian:
Thanks for the offer! Sorry to miss you this time, once my copilot heard you used to work for NASCAR he wanted to meet you! Anyhow, we will be in Concord until Sat AM. Thanks for the BBQ recommendation, will check it out tomorrow night!
Cheers Dave
PS I have a film of the 1940 Daytona Beach Beach/Road Race. My grandfather had it and I got it when he passed on. My grandfather thru the Daytona Exchange Club was one of the sponsors and was friends with Bill France for many years. Who should I speak to at the NASCAR museum about this?

Prologue 2
Had to show this. Ben, my copilot for the trip, torquing down the front wheels (did a front brake job last week and it drastically improved things).
Same guy doing the same thing 5 yrs ago (11 then, 16 now and driving!)
So I think we are set. Probably brought too many car parts but since this is the first long trip I am being cautious. Weather will be hot tomorrow, cooler and rain on Thurs once we get closer to Concord. Wish us luck!
Cheers, Dave

Prologue 6 July
Well it's on for tomorrow! The car is 90% packed.
All this is for the car! Clothes will go into the back seat. Sorry for the huuuuge photo size. I appears my quick resizing SW has fled the scene.
Ready to go
Well that is it on photos for this post. Looks like it will be > 93 degrees tmw so that will be a good test.

Actually I have a Carter WCD 663S. My install of the vacuum lines isn't stock so may not help you much. I will see what I can do while on the trip.

Thanks! Jack, yes I will be doing US highways and State roads. Going down US 15 most of the way, then avoiding Winston-Salem/Greensboro by using NC 49. Going to break it up into 2 days each way.
Cheers, Dave

All:
Thanks for the encouragement. I did check all of the valves just last week. Only 1 a bit loose, number 6 intake I think. I tend to leave mine a tiny bit on the loose side as I would rather put up with a small bit of noise rather than risk burning a valve.
As far as this being a valve issue, I did do the oil test and compression test which was fine at 100 lbs on #4 so I am thinking more along the rings side.
Although I should add that there has been a double tap noise that has been there for a while. I did a post on this last winter I think. It sounds like the tap is coming from down lower in the engine but sounds going through metal can fool you as to location. I did do a remove-spark-cable test on all cyls and the tap did not go away so I don't think it's from a connecting rod. Also the tap seems to be on cam rpm rather than crank.
I have a setup where I can detect noise using a vibration to sound transducer and, using an amp and noise cancelling headphones, can really pick out noises in the block. I tried that on the tap but still could not isolate. It sounded a bit like in the cylinder 3 area. Perhaps a dragging lifter. Anyhow, more troubleshooting will have to wait until I get back. I hope that sound I hear isn't whistling past the graveyard!
Cheers, Dave

In prep for my upcoming trip next week (see here:
) I am going over the car with a fine toothed comb. I noticed a small periodic dip in the vacuum at idle, not much (an inch or less) but it wasn't there before. As part of the process I did a compression test. I haven't done one in about 3 years. As a reminder, the rings and valves were redone in 2014.
Compression test results. Starting at #1 going back: 110 105 100 80 100 105 105 110 Notice the dip in #4. I shot some oil in there and it came up to 100. So maybe rings not broken in properly, or my careful ring clocking got declocked somehow, or something more serious? I did a cylinder balance test at idle, and sure enough, all of the others dropped about 50 RPM while #4 only dropped 20 to 25 RPM. I could not specifically tie in #4 to the slight vacuum dip, however. May be 2 different issues.
Double checked ignition - spark voltage is the same across 3, 4, and 5. Swapped out the #4 spark plug - no change. Plugs all looked normal including #4. One interesting thing - if I do the balance test at 1000 RPM, the drops are all the same, #4 is good. So it appears it is what it is for the time being.
Since I am planning on taking a trip of about 750 miles total, does anyone see any problems in going ahead with this? 20 lb drop in compression is a significant but not huge amount. And the tailpipe sounds clear, no apparent missing. My plan is to monitor, paying attention to vacuum as usual, and maybe doing a quick compression on #4 at about the trip halfway point. I don't see me risking any catastrophic damage by doing this at this point. We all know these engines are very tough.
Anyone disagree with my approach? Comments? You can follow me on the trip at the link above to see what happens!
Cheers, Dave
