Time to Replace the old F Engine (1 Viewer)

[mrboatman]

I`ve had some blow-by for the past 3 months or so well actually a lot of blow-by. So I did a compression test and it went #1=132 #2=60 #3=135 #4=137 #5=146 #6=155. So today I stuck a bore scope in to #2 spark plug hole and now I know why so much blow-by.

very handy gadget the bore scope. I'm not sure what I'm seeing in that pic, but it looks bad.

Exhaust valve in head? if so just get a new head. All the other numbers are good.

I wish that is the top side of the piston you can see part of the top ring. But it still runs good just has lots of blow-by

that is the top side of the piston

And is that a corresponding notch or groove in the cylinder wall?
Time to move up to the mighty 2F.

Thanks for showing that pic. I have a lot of blow-by in my early '63 ('64 1F) but my compression numbers are all really good. Good luck with "fix" or replacement.

Looks like the mess I was in.

Where have I seen that before (lol)

Haven't you guys heard of JB Weld?
On a side note, I bought a cheap scope online on a whim and I love it. I’ve looked in engines, dryer vents, attic, bird houses, spied on my kids. They are great!

Now that would create an issue.

Do a “dumbed down 2f”. I did it on mine and it is a major improvement.

Thats the plan I`ve already got a "wanted" ad in the classifieds.

Well found a nice 2F from a 84 FJ60. Thanks @Trail Rated Got it home and unloaded and power washed today. Now to start the desmog

Your 40 winch hoist is pretty awesome.

A gin pole is a really useful piece of equipment.

Yes it is. It makes lifting and moving heavy items a little easier.

Got some time today and ran a compression test. these were a cold engine. I was happy
#1 = 160
#2 = 150
#3 = 150
#4 = 150
#5 = 155
#6 = 160

Nice compression numbers!

Don't dumb it down too much. Keep that carb!

I'm about to start hooking up the vacuum lines on the desmoged 2F I got from an 83' FJ60 in my 69' and have realized that if I use the non USA carb I bought instead of the stock one I give up a bunch of vacuum ports that are essential to the HAC and ICS. One thing I really disliked when I used to drive the 40 with the 1F was how it bogged down and ran really rich at high altitude. Coming from sea level so barely made it over most the passes in the Sierras.
