Off with its head (s)!!!
05. Mar 2009 at 21:05

Had a spare hour this evening so whipped the heads of Mick Dundees car

The engine bay now:

Close up of the bores, note that the crank is set to 30 degrees before TDC and no pistons are at or near TDC and hence its classed as the 'safe' position

And another pile of bits!

The alternator has got to come off yet to get new bearings fitted (very rough).

As I re-build the heads, I will do afew pics plus I will profile the F and N cams used on the 2.6.

You should also be able to see, during the head rebuild, how much better than the 2.5/3.0 the exhaust manifolds are!

Unbelievable Lots of varying pics would be handy for future reference for other future threads etc (eg, someone asked the other day where core plugs were in heads)

I had looked at that earlier, remembering you had mentioned it before, but it does look that clear on photos Undecided

VXL V6 Omega Lord Offline Posts: 5306 Gender:	Re: Off with its head (s)!!! Reply #13 - 05. Mar 2009 at 21:24 Real stupid question here but does the block sit level in the car? I only ask because I notice there is coolant at the back of the reservoir area where the oil cooler sits but not uniformly across the whole of it? Or has all the kit you have removed from the engine lessened the weight of the front of the car?

Wouldn't be a DIS in that shot anyway, its attacehd to the head!

Well get better pics of the pistons once I have cleaned them all up.

The engine bay will get a bit of spit and polish whilst its stripped down to!
