1973 MGB (No O/D)
Start car, minor mechanical noises, warm car up (drive 1-2 miles) and loud
knocking starts, no rumble or slap, noise is now there in idle, does not
increase with load. Timing set, valve lash set, carbs set. Is it the Rod Big
end
bearings?? How can I prove this??
If so...
Q1. Can the sump be dropped without removing any other parts ??
if so...
Q2. Can the Rod Big End Bearings be replaced this way (by me, in the
driveway???)
Q3. READ MY WRITS(!!) Engine OFF, Ignition OFF, pull car into sun in driveway
Tach reads 0 r.p.m.... sun warms up car, tach starts to read... After a while
(with a COLD Unstarted Engine) Tach reads over 3000 r.p.m. HELP!!
