Does Jim do on-site “vacation” trips?
I’m guessing a lot of these “issues” apply to 1F engines?
Are you familiar with the term “force multiplier “?

Just curious. But if a 2f head is shaved to the maximum with stock pistons, what does it up the compression ratio to?Yes, in December I was on a real vaca and met up with a couple Mudders to deliver a desmog, carb & dissy, as well as look over their FJ40's and discuss what to to do and why to do it.
3 days ago I was in Colorado, laying hands on a forlorn FJ40 that just wouldn't run right after a new (rebuilt) engine, new (rebuilt) manifolds, new (rebuilt x2) carb and new (good used ) dissy. It runs great now.
For a $50,000 vehicle, it might be worth $3,000 to fly in an expert.![]()
2f with domed pistons, stock head, bored .030 over.Which head & pistons? What size bore?
It is about 470 miles.
Road trips are cool, go for it!

The usual items that need attention on a rebuilt 78 2F: check for correct pistons, install correct spark plugs, carb re-rebuilt correctly, jetted for altitude, flatten & seal carb insulator, correct the hatchet desmog, dissy tested, junk chicomm parts replaced (air filt, PCV, fanclutch...), break-in engine, retork head & re-adjust valves, timing set for altitude,...Really interested to know what that one in Colorado needed. Great work Jim![]()
I'm not one for opinions, sorry.@FJ40Jim What is a "normal" turn around time to rebuild either a F or a F.5 engine. My 1970 FJ40 F engine has compression numbers which are lacking consistency although it runs very well. I have a F.5 that is available for purchase and if the newer engine would be a better fit for rebuild, I assume (I hate that word) it would be a better engine and maybe easier to rebuild. Your expert opinion please.
I think that this was what happened to my '75 with a leaky windshield washer nozzle and the hood down.When storing an engine outside, don't worry about covering it. The air cleaner will do a good job of collecting rainwater and trickling it down the air cleaner stud. The water will coat the carburetor and cylinders w/ open intake valves w/ a coat of protective rust.
