    89 SHO Compression Test Results

    I decided to do a compression test on the front 3 cylinders since they’re easily accessible, in my quest to find a miss……. #4 is 170, #5 is 210 and #6 is 170PSI Within the spec of 171 to 199, BUT more than a 10% diff between the highest and lowest. Thoughts?

    Coolant leak - use stop leak?

    Anyone actually find valve shims that needed replacing?

    I worked at a Ford dealer in the 1990s, the service manager had a 1989 SHO and did his due diligence for his 60k and then 120k service. His advice when I had my first SHO was to use a quality oil and not bother with the checking for clearance and use shims unless you hear clattering. The wear...
