What does the failure look like has the head fallen of the valve or have you lost the stem as well
Generally speaking these are very good engines with few real problems having said that Mermaid do push the power from designed power of 70 hp

Yes the head has come of the valve stem the last one that went shaterd cracking the piston in two the engine only had 10hrs on it Many thanks Jamie.

Do you know what state the valve guides are in one tell-tail of a problem will be excess smoke and oil-use which is difficult to define with a Ford if in doubt get the head done, skim, new guides, check valves and check alignment on rockers etc Des

On second thoughts don’t put the old valves back if you have valve guide wear problems because they may already be stressed and likely to fail although new valves will be expensive it is false economy to not change them. Des
