I recently replaced the engine in my 92 and we used a fork lift to pull the whole drive train it was very sketchy to say the least. I will say that the effort was worth it, she runs better than I imagine and I didn't think the old engine ran that bad and it was on its death bed.
In my experience with weight handling/bearing equipment the safety factor is a 5:1 ratio. I think you'd be ok and any area of concern could probably be shored up with more support/gussets or beefed up suspension. Hey you can build anything, it's just a matter of $$$ and imagination.
Just...
For what it's worth I took the head off and sent it to the machine shop. I did need some new valve seats but the head was actually in really good shape. The "corrosion" I was worried about was only casting material.
I was impressed that the cylinders still had cross hatching (a little wear on...
Good logic, thanks. Other than the coolant leak in the front of the engine that prompted this exploratory, the old girl runs pretty good. Don't fix it if it ain't broke applies. I appreciate the help.
Look "thru" the coolant in the head. The shadow is jagged corroded metal that easily bends and flakes off. The "shell"of the head is fine, I'm worried about the channels and cooling ports inside being corroded so bad that they fail.
Ok for some reason my photos will now post. Look thru the coolant and you can see the jagged metal reaming from what has rusted away. When I got this FJ is was running rusty water at the coolant.
Just looking for a good mechanic in the southern Va/ Northern NC area? I need someone to look at the head on my 1992 FJ80. I just don't know enough about how the head is constructed to know if the corrosion I found inside the head is terminal.
This is where the t housing bolts to the head. Look thru the coolant and see the "missing" metal. Do I now have more surface area for cooling or do I run the risk of major failure? My plan is to drive my family of 6 across Canada to Alaska......
Anyone removed their thermostat housing to find severe corrosion in their head? No major cooling problems other than coolant leak while warming up at idle (what prompted my looking to begin with). I guess I'm wondering if I should run it or replace the head before she fails.
This is a 1992...
X2 on useless gasket! Same thing... turned to mush. This has been a blessing in disguise, though. The T housing was actually cracked and the base (where it mounts to the head) didn't have a gasket. So I have all the parts on order and hopefully this will solve my coolant leak during warm up...
Yes, that is correct, bubbles are coming from the T Housing. On my way to first team Toyota in Chesapeake va. I'll let you know what the results are. Thanks for the quick feed back. This place has been great for my FJ!
