Cylinder head refurb continues 01-04 Feb 2006
Apologies for the few out of focus shots, I must get a better
The cleaned up valve seats
The other end of the head
Nice and shiny
Valves waiting to go back. The spring compressor that I bought
did not have enough depth and has gone back for a refund. Until it's
replacmemnt arrives I can't fit these......
These are the inserts and air shrouds that the injectors plug
Pretty cacked up. I'm glad that I removed them to clean them
12mm hex bit used to uncrew the top brass bit. You can then
remove the bottom plastic bit by GENTLY tapping on then using the
1/2" drive extension bar and a hammer. You might also want to
try a 13mm hex bit, as my 12mm one was very loose...
Those nicely cleaned valves again
The head now all cleaned up, everything removed (that's going to
be.....). Just have to mask it off now to paint it
I cleaned it up using Flash (orange) and a rotary wire brush in a
I cleaned it all over
Except the underside, which had been skimmed by the machine shop
You can see that I got most of the crud from out of the ports
Also out of the bores into which the injector shrouds go.
It's pretty clean
All masked up, and ready for paint. I used an old camcover to
stop paint getting into the inside of the head. The old spark plugs
were installed to stop the spark plug hole threads from getting
paint on them
Exhaust ports masked off too...
The 2079 crankshaft locking tool, a 27mm socket and a 2 foot long
3/4" drive bar
The crankshaft locking tool goes on here like this (you have to
turn the crank to get them aligned)
I used an axle stand to support the T bar whilst trying to remove
the crank locking bolt.
One Mother of a bolt. They are supposed to be tightened to 450Nm
(340Ftlb or thereabouts), mine was only about 30Nm... If that...
Once you have the end pulley waggled off, you can see how short
the end of the crank is. It only sticks out of the block approx
The end of the crank. I'll be replacing the oil seal before the
pulley goes on.
The crankshaft pulley and damper assembly
Which is fairly cacked up. I'll de-rust this and paint it
4 Allen screws secure the timing belt pulley to the main pulley,
these too will be replaced. The timing belt pulley appears to be in
Back to the head. A quick coat of etch primer
On bothe sides
I used silver hi-temp paint below the exhaust manifold
And then painted the whole head with a metallic silver paint.
It's a fairly close match for the original aluminium. But not
Looks good though.....
