Hello.
Recently my 07 AT FJ started to make a metallic sound when starting, I ignored it and it became constant with the driving, I thought it might be that the lifter valves were dry so I checked the engine oil level and it (inexplicably) ran out of oil. I added 4qts more of oil and continued driving hoping the lifter valves will get charged of oil and stop the sound of them hitting the camshafts. The sound became louder and the car lost a lot of power so I went to the mechanic and just with the sound he said that he was 99% sure that the issue was at the crankshaft, maybe the crankshafts rod bearings and maybe even the crankshaft itself got unbalanced. The strange thing is that the oil level light or the check engine light never showed up, and it never overheated.
My FJ is currently at the workshop and they are taking out the entire engine to check what happened, but I will probably need to do a complete overhaul, or at least for sure all piston rings, oil pump, bearings and washers and rectify the crankshaft. I already did the timing chain kit with all the gears and vvti stuff like 20k miles ago. And I think the pistons will not be necessary, the engine has 112k miles and it has never overheated.
Does anyone has done a complete rebuild to a 1GRFE? (1st gen, single vvti) and maybe can share a list of parts needed or a kit that comes with all the parts and even experiences/reviews of the quality of the products.
We (the mechanic and me) think it will be better to do a complete overhaul than to buy a used engine, because here in costa rica, when buying and used engine we only get 1 month warranty, and the engine can be more damaged than mine, so doing a complete rebuild will maybe cost the same or a little bit more but I got my engine almost good as new.
All the help and comments will be appreciated.
