ih8mud community!
This is my first post. I've been learning from this forum for half a year now.
Thank you to all the active members who posted all that helpful information!
I lived in Canada for the last 4 years and a friend of mine, also a cruiser geek has sold me his 1983 BJ60 3B with H55 transmission. I was hooked right away and spent an entire winter restoring it and dreaming about the places to go to. I fabricated a heavy duty roof rack, swing arm bumpers, etc. I think I will post a restoration documentary at some point...
About 2 month ago I left Canada to go on a road trip around the USA from Toronto, down the east coast, through a lot of national parks and up the west coast again. Most of the problem that have appeared were easily fixed due to this amazing forum!
Now, it's time to become an active member myself and maybe help out some people with similar problems through publishing this one:
About 500 miles ago I experienced a power loss. I was going on the highway (with 60 mph max speed) and all of a sudden I couldn't climb the smallest hills anymore. Shortly before that I noticed that the engine makes a more distinctive clacking noise, mostly noticeable in lower rpms. I thought that my valve clearances were off maybe, even though I adjusted them about 6000 miles ago.
At this point I should probably mention that I am not an experienced mechanic at all and most of my knowledge comes from researching things online.
Anyways, I adjusted the valve clearance (They were off) and thought that would fix the problem. For some reason the clearance had changed rapidly during 6000 miles of driving, which is a mystery to me too... Sometimes when I experience the power lossand I am not even able to get up a hill in 3rd gear the engine starts to overheat as well, once to the point that I had to stop and cool down. I only have the factory gauge though. (I know it's not very precise) I would say it's about 30% less power. My friend assumed that I have air in the system. This was true, I bled the system and injectors and found a few bubbles. That still didn't fix the problem tho...
I'm just gonna list the things done to the engine to simplify this thread a bit: (Nobody wants to read an essay )
The problem:
- 30% power loss(even on flat road) Appears often, and disappears sometimes after having cooled down a bit. Then all of a sudden all the power comes back.
- overheating during power loss(especially when going up any bit of slope)
- louder clacking sound then usual
- Some black smoke when shifting down or accelerating. (I am in New Mexico right now with 8000 feet altitude. I have read that it is normal because of the air intake...)
Before I left i did this to the engine:
- I changed all the fluids, (Engine, transmission, transfer, diferentials)
- Changed oil filter and fuel filter. (Bled the system)
- Adjusted valve clearances.
- Lubricated hubs and joints on propeller shaft
- Started mixing in a bit of 2 cycle oil and injection cleanerin the tank.
What I have done to fix the problem:
- I changed the hand priming pump (Bosch) The old one was leaking and I assumed air to get in.
- Bled the system again
- Checked all the fuel lines for leaks even the one that goes into the tank. (Cut a maintenance door inside the truck to look at the fuel line) Everything was fine. The bottom got oilsprayed, most of it is pretty messy but very well preserved.
- Changed the air filter
- Checked propeller shaft and other parts for loose connections and play. (Propeller shaft was loose but the noise was the same after tightening it)
- checked coolant. (It looks green yellow ish and is a bit foggy but it doesn't look oily or so.
- checked water hoses, everything seems to be fine, Theradiatordoesn't leak either.
What I plan on doing next:
I bought seafoam to clean the engine. (Fill up the fuel filterwith it) Since the amount of miles on the engine (possible without any conditioners etc) is unknown, (odometer broke at 336.000km) there could be a lot of dirt that might have seized up an injector. I have read that a seized connector could cause a clacking noise as well. An of course a power loss...
- Should I try to mess around with the fuel setting on theinjection pump?
- I just found out that my fan is loose on the shaft, which would mean that it slips on the shaft when it has to work hard/has more resistance. I felt the nut but i could feel some pins (probably a lock nut I assume). What's the best way to tighten that? I doubt it has anything to do with thepower losstho (correct me if I am wrong)
- I also just saw one of the hoses with the banjo connection, going to the fuel filterhas quite a few cracks. Can it be that it's sucking air through them? I think it would leak diesel if they would have a hole somewhere... or maybe not? (I guess I should replace it anyways...)
I apologize for this essay like thread, I really hope to fix this problem since I am going to drive through the hot canyon lands soon... Please let me know if anything needs clarification, or if you need any more information to help me solve this problem. I very much appreciate all of your help! Thanks in advance!
