.... their english is pretty poor but they try their best.   ....

But is your Deutsch any better than their English?   

I am fluent in several languages, just not german.  I did my best to learn some while i was there, but mechanical parts were not in my dictionary

There's only so much I can fit in this amazing brain of mine 

[Gaffers]

The does look a but close, it was a while since I did mine so I cant remember the clearance.  If you dont want to get it skimmed maybe you can get a metal ruler and some feeler blades to see if it is warped.

edit: is that valve properly seated there?  Besides once you grind the valves in they will sit marginally lower

I'm impressed with anyone who can speak even one other language.

Debs is still the best linguist I know

that the head must have already have been skimmed some time in the past?

how much more can be taken off before the head is no good?

There'll be a minimum thickness for the head somewhere, but the fact the valves are so close to the head's face doesn't mean it's already been skimmed. Where the valve is so close, the piston will have cut outs in the crown to accommodate them.

also will it not rise the compression in the engine???

It will, but only very marginally and not that you'd notice. When you skim a head, you're only removing the very minimum of material to ensure it's flat and maybe remove corrosion around a water way. You'd be surprised how big a step just a 0.005" cut looks.

next was to clean the block,got my scraper and nipped to get some petrol to get it crystal clean!!!!



also gave the pots a good clean (not with scaper lol just petrol,cloth and plenty of elbow grease lol)



happy with that :-) only took about 30mins :-)

so thats every thing cleaned (all mayo gone) labled (so goes back just where it should)

 and as soon as the hg kit arrives (and i get a day off ) will all be put back together and hopefully that will be all the probs sorted :-) well apart from the cracked exhaust manifold but that will have to wait till next pay day lol

[griff2494]

and no when i took the pic of the 1 valve sat in the head it was not sat correctly ie its not ground back in yet nore did it have the spring connected,cant do that till hg kit arrives and i get the new oil stem seals

but up to now the head gasket has been much much easier that the rover 1.8 vvc (twin cam belt) i did in my 16v mini conversion

then again its not back together yet lol its always easy to take things apart,its putting them back together thats the testing bit lol esp getting them to work again lol time will tell

[griff2494]

as you can see on the above pics of the block,the pistons do NOT have indents for the valves,they do curve at the edges but weather this is enought to miss the valves if i get the head skimmed im not sure :-(

anyone no where the min marker on a 2.2 head would be?
or what it would look like???

[Abiton]

Don't forget the thickness of the gasket will add to the clearance. 

[griff2494]

mmmm never thought of that :-)
just going to start a new thread and a google search for where is the marker on the 2.2 head to say the min for purpose of skimming

[PhilRich]

Griff, the cylinder head measurement should be 134mm as this screengrab of TIS2000 shows.  Hope this helps 

[griff2494]

cheers mate :-)

ive just copied that pic mate incase the mods delete it!

but ive got tis2000 myself but dont relay no how to work it ,think i better have a look

once again cheers mate

[griff2494]

erm now im all :-(

after the post ref thickness on the head 134mm
im very :-(
just got the micrometre out and heres the results ,im confussed as the car ran ok




its reading !!!!!!!!!!!!!!!!!  127 mm !!!!!!!!!!!!!!!!!!!!
that means its had 7mm skimmed in the past !! that cant be righ!!!!!!!!!!!!
any ideas
i really need to no if theres a min marker somewhere on the 2.2 head!!!

[Andy B]

....
just got the micrometre out and v......v

That's a vernier aka a very-near 

[Andy B]

see if you can take another piccy without the flash.

It's too difficult to read due to the flash.
