The original 2.5 engine needs some service like new belt and adjusting the valve clearance, when the engine is really hot you can hear the crank make a clock noise (don't they all!)
So this engine will need some work, this 2.5 is a great engine but it;s a big step back compared to the 3.0 24V.
I have the following engines laying around but they all have some mechanical failures.
164 3.0 24V cranck bearings, no valves
164 3.0 24V broken belt and damaged crank
155 2.5 12V damaged sump ( damaged crank and valves)
164 3.0 V6 12V 1 melted piston
75 3.0 V6 12V perfect condition.(spare engine for my 75 24V)
Could yo guys advise me on a good mix of parts from these engines.
3.0 12V with 24V pistons for 10:1 or 2.5 with 3.0 pistons (2.

3.0 with 2.5 heads (smaller valves)
