[QUOTE="t_jones98, post: 116599, member: 20639"] Picked up a non-running 751C with the Peugeot in it, has some of the details of work done over the years but I doubt all. Been sitting for the last couple. One of the invoices that I received from the previous owner was for a cylinder head replacement, but no idea why. I started the cleaning process, new filters, battery, etc. Bypassed the fuel tank (haven't had a chance to flush it yet). Bled the fuel system all the way to the injectors, appears to be getting fuel, not sure about the pressure to the injectors from the seemingly problematic Lucas injector pump. Won't start. Ok, fair enough, next step, compression testing (PSIs are approx) Cyl 1 - 325-350 Cyl 2 - 325-350 Cyl 3 - 200 Cyl 4 - 75 Leads me to two conditions: 1. Cylinders, pistons and rings 2. Due to a new cylinder head, the valves were not shimmed correctly With my "test/fix/replace the least expensive first" attitude, next step is to pull the valve cover and check for valve clearance. Followed by removing the head and checking the cylinders visually, valves and seats and such. Which leads me to my main question here... can you remove the head without removing the exhaust and intake manifolds and other items that you can't really see from the back of the machine? I'm trying to do this without pulling the engine. [/QUOTE]
