: D Hi I have recently rebuilt my 1985 model 2.6L LWB ex army series 3 Landrover engine. Standard pistons were not readily available so I installed very similar pistons that had a marginally higher gudgeon pin. I expected lower compression but went ahead. The motor is running really well on LPG and has plenty of grunt but when I tested the compression it came up at 100psi not the 170 that would have come from the standard pistons.
My question is:
Can I expect any future trouble from having the reduced compression and do I need to start hunting for the standard pistons?
Thanks for any help you can give.
Regards Aussie Ken.
