So so so so SOOOOOO down, messaging u. Could get that 25% of the missing fun back:wanna pick up a troopy I bought in IL and drive it to Utah?
Yea I figured. That’s why I was so confused, unless I just lost all oil pressure and it spun a bearing and really messed with the pistons causing such a drastic change in PSI.Something is up with the compression.
#1 and #2 were 450 and 425 respectively before the engine came out of the silver Troopy.
(My gauge broke before I could do #3 & #4)
Always can try a different one at some point, this one was brand new than @LuckyDevil just got, you would think it’d be somewhat accurate. If the head gasket did let loose then why does knocking get louder when you’re at the bottom end of the engine, like significantly louder?If thats the case, then most likely a head gasket or loosened head all the way. I "almost" find it impossible that it went from over 400psi to barely 320ish.
Now it's either some serious gauge discrepancies or the gasket let loose.
@theglobb do you have another gauge to try?
Either way, a mechanical knocking is a bad sign.
It wasn’t overheated at all though. Temps running cool on my factory and aftermarket temp gauge 180f when things started getting funky and 185 by the time I shut the engine down while driving. Shot up to 210 since I shut my engine off under load while moving all abruptly, still nothing insane or near overheating… aftermarket temp gauge is in the side of the engine block so I would’ve thought I would see a change in temp that’s noticeable… might not have time to pull the head for a while, I get back after this trip and gotta pack for college. I’ll see what time I can spare.Swallowing a cracked exhaust seat after overheat will cause knocking and damage a piston maybe or maybe not beyond repair. Bits of steel will embed in the aluminum piston. In my case it didn't damage bore, rod, or crank. broken rings causing piston slap is more of a "tick" than a "knock". lots of smoke from the oil fill is sign of overheat...........on my 3BII a repaired freeze(by previous owner) plug blew along with all the water from the engine at 60mph on the highway. Water went away from the temp probe and I never saw the guage go up, and I was monitoring it.................I think when J. pulls his head the problem will reveal.
Also just fyi, this didn’t work out. As cool as it would’ve been, it also would’ve been pretty sketch driving a turbod 2H with 620,000kms that far especially with my recent luck with Toyota IDIs. That shouldn’t be turbo’d. He was lucky enough that his transport truck ended up working outSo so so so SOOOOOO down, messaging u. Could get that 25% of the missing fun back:
We are going to glacier!!! Probably on the 20th or 21st, don’t know how we’d meet up if cellular reception is bad. Shoot me a PM with your number and hopefully I’ll be able to check out your prado!!!So awesome that you were able to get on the road, would be even more awesome to caravan with a Troopy! If you feel like driving 2.5hrs north from Missoula give me a shout, Glacier National Park is only 45 min. from my place and well worth the trip. I need a good excuse to take the Prado out anyway!
Isuzu 4BD is supposed to be a good engine and significantly quieter than a cummins 3.9 4BT. If you do the research and figure out the engine to H55F adapter please post. Good luck.Yea I figured.

Future engine thoughts…
That Isuzu 4bdt1 is looking pretty appealing, especially for price/performance. Odds are I won’t be able to pick up a decent 13 or 14B for less than 5-6k that I can find or have been offered. I could pick up an old Isuzu NPR for 2-3 grand or cheaper. Then the additional costs of fabrication and adapters etc etc. then sell the rest for scrap or part out. also with the amount I drive my car I’d much prefer diesels efficiency and simplicity compared to an electronically controlled V8. 4cyl much easier to work on, mechanical diesel much simpler, etc etc. time will tell
Are really the 14Bs so pricey in the States?Future engine thoughts…

Should you choose SE Asia for that just ask.I barley recall being 18-20, broke and full of ideas.
You will figure it out, best lessons are often learned the hard way.
Old man advice; travel overseas as much as you can before you are 30-35yrs old. Besides school, I would put all my money and effort into that if I was you. Troopies are a tough one when you are young and broke.. Latin America is GREAT and CHEAP if you do the backpacker thing.
Have fun!
Cheers

i put a 4BD1T in my FJ55 back in the day, GREAT engine, adapting was a pain and hasnt gotten any better over the years, its a shame really.Isuzu 4BD is supposed to be a good engine and significantly quieter than a cummins 3.9 4BT. If you do the research and figure out the engine to H55F adapter please post. Good luck.
Last Saturday. It's the 4th Saturday of the month.How long are you staying in SLC? I think they're doing cruisers and coffee on saturday.
nope, been doing tons of research for the past hour or so. Seen it done many many times before on mud. Many different ways to do it, well like 4 different ways. I’ll keep y’all updated once I find a clear routehave you made sure you can acquire whatever way to adapt a 4BD to your H55f?
