My '72 2000 GTV has 30% leak down in #3 cylinder, with the apparent culprit being the exhaust valve guide. Temp check of the headers as the engine warms up shows #3 consistently 20-30 degrees below the others. Pistons are stock but hi-lift cams were installed back in the '90's by previous owner.
Q1-Should I go ahead and get the valve job done now to correct this problem? What is downside of driving it this way to failure or until leak down is greater? Q2-How difficult is it to pull the head and take it to someone for rebuild as opposed to paying someone to do it? I am reasonably good mechanic, but no experience w/Alfa engine work. Q3-What should I expect to pay for a complete valve job at an experienced Alfa shop? I am in SF Bay Area, so lots of options out there.
