Hi, guys,
So... I need a second guess... I'll try to keep this short. Mine is a D50 89' 4x4 with the G54B. I bought it 2 months ago knowing the head gasket was blown and had to be replaced. I've not removed the head yet but I ordered a small bore camera to look inside the cylinders. I think not only the head is gone but also the block looks toasted but I'm not a pro so could you guys give me your opinion?
These are the links for the videos I took, sorry for the quality, the steadiness and my face. I was trying the get an overview of the cylinders but it was not easy. Also a picture of the sparkplug if it can help in any case.
Cylinder #1 : https://youtu.be/YdioWYR03JU
Cylinder #2 : https://youtu.be/0z55KMRKgZc
Cylinder #3 : https://youtu.be/McEKgVCTtJg
Cylinder #4 : https://youtu.be/WaIXsQHhF50
Cylinder #1 & 4 looks OK but if you look closely there something that look like a crack on the #1. Would it be possible the block be cracked between two chambers considering what you see on all the videos...!?
Cylinder #2 is the worst, look like there is metal bits in there, parts disintegrated from the head?
Cylinder #3 looks better than the second but there black spots on the walls, from overheating?
Most of the walls have vertical mark which I think is a pretty bad sign...
I'm pretty bummed tbh, I feel dumb not doing this before ordering parts, brake, alternator and other stuff. My plan was to, worst case scenario, take the head to a machine shop during the winter if warped or if not salvageable buy a new non-jet head. Now it seem like the whole thing would need to got out and it's not the same deal. I've considered swaping the engine at first for a 4g63 but KM145 you know... or maybe swap the head... In any case, it involve a lot for now and I was hoping to at least get the truck back on the road with the current engine for a little while.
The truck runs, I've started it for about 3-5 minutes twice, seemed like there was a power loss but it was at low speed and I kept crossing my fingers its was only a matter of cleaning the carb or broken vacuum lines.
Anyway, pretty disappointed right now but maybe you guys have a different opinion on the state of this engine and have suggestions for me if you had to be on this situation. Let me know.
Thanks,
