Re: Interested/questions about a motor swap on 98 Eldorado
No, you cannot swap a VIN Y (LD8) for a VIN 9 (L37) or vice versa.
Remember the '99 has the worst HG failure record. If you replace the motor with an untouched one, you may have the same problem down the road. If you replace the motor it would be advisable to pull the heads, drill and tap the bolt holes and insert or stud it. Not doing so is kind of like playing Russian Roulette.
