<VV> Axle shafts, wheel wobble & detonation.

Hugo!!  You need to remind us of What vehicle you have…  you are not the only on in the UK.

The Detonation?  Engine is overheating!  And when you say the FINS  looked clear from BELOW….. tells me your cylinder baffles are missing!   They FORCE  more air over the heads…   Then you mention leaves….  Time to remove the Fan’s Shroud….  Clean / blowout the oil cooler fins….  Shine a light  from below  and see if passages are clear…  if not make them clear.  See pic!

The main problem 
is it overheats after about ten or fifteen miles - even on a cool 
Florida day - & I have to wait for it to cool down before I can go any 
further. I took the bottom shields off, expecting to find the fins all 
clogged with leaves where the storms had blown them in, but they all 
look clear enough. I was thinking of putting a hose pipe down there 
through the fan & see if anything comes out. Or would an air line be 
better?
And it detonates like crazy - not pinging, but a heavy knock. At first 
I thought it was piston slap, but it doesn't do it from cold. It does 
start doing it before the engine gets the slightest bit hot though - 
before it has even reached running temp I would say. I haven't checked 
things like ignition timing yet. I'm not quite sure which job to tackle 
next, so I thought I'd throw this lot out there to see if anybody has 
any suggestions?
