Hi all, I have a 105 series that the previous owner fitted an 80 series turbo to (max boost 10psi)
I don't know if the turbo is a factor or not but the engine is down on power, has blow-by and the compressions are less than 200psi. It's amazing that it still starts. It holds great oil pressure, uses no water and doesn't overheat so I'm guessing the bearings etc. are all good still
I live on a remote island so getting parts and/or covered spaces to work on a vehicle is hard. I may have access to a good used 1HZ motor but before I spend money on purchasing that I'd like to take a look inside my own engine.
Does anyone know if I can change piston rings with the engine still in the engine bay? Perhaps someone with an 80 series has done this already?
I understand that I'll have to remove the head, sump and conrods. I'm just unclear if there's enough room. It's possible that I'll find cracked pistons or something else serious of course, but if the motor can be 'freshened' in-situ I will have a go at that option first.
