That was excellent TY the best one I’ve watched because I had no mark for crankshaft sprocket and the TDC on the pulley being straight up was great info. I have a housing pointer for that and was trying to determine what notch was TDC
Do you have spark, fuel, and compression? Check for spark and check for pulse at your fuel injectors. Make sure they’re powering on and clicking. Let me know what you find.
Howdy. I have a new-to-me 1998 Nissan Pathfinder 4x4, automatic, 3.3L VG33E 4th VIN digit "A" motor, made 10/1997. It has one or more bad piston wrist pins, and a confirmed bad crankshaft due to excessive bearing failures from oil loss. Does anyone know if the pistons in a 1996-2004 Pathfinders, QX4, Frontier, or Xterras can be removed and reinstalled through the bottom of the motor (oil pan), with the motor still installed? I also have a bad crank so I have to have it removed and machined too. The rest of the motor is clean, no oil burning, and low miles (165,000). I hate to swap it for an unknown possible problem motor if I can do it this way instead. I haven't been able to find anyone online who has accomplished this, but maybe it's not possible due to clearance or whatever. Do ya know, or take a guess if ya been under one like this? Thanks much!
I think it would be very difficult nearly impossible to remove the crankshaft and piston with the engine still in the vehicle but if you could get the crankshaft out, yes the piston could come out through the bottom of the engine.
