Do you think I need a new one? B)

Was course opener for the funky elephant road rally on Saturday night, used about 8 pints of water in the process of getting round!

 

Also I don't think this makes for a very free flowing exhaust!

 

Head looks a bit corroded, more pics here - http://www.saywell.net/gallery/headgasket

You could sell the two seperate cylinder bits as timmey mallet lookalike glasses on ebay, they are *rare* you know :)

Mine was the same the first time I took the head off my engine (hadn't blown though). There was a big pile of rusty flakes and silt built up around no.1 liner, make sure you flush it all out!

 

I've had the downpipe go the same way as well. With my current one I've welded the two layers of the dividing wall together to try and prevent them from separating like that...

just took mine off, whats the best way to flush all the flakes, oil and water ? do i need to take apart my cylinder head before i get it skimmed ? what the best way to clean all this up ?

Don't bother skiming the head if it doesn't need doing.

If the gasket looks as bad as that then that's the cause for the head gasket failure.

All garages seem to want to skim heads " Just to be sure" and will tell you it NEEDS doing.

Just look at this post of mine here to prove the know it all Mechanics I talked to (not the helpful forum members) telling me the Head was warped when it's clearly not.

The corrosion is away from the compression ring so you should be fine. Clean it up with a bit of emry paper wrapped around a flat block.

how would i know if its warped or if it isnt ?

 

i dont know of anything i could use to make sure it was perfectly flat

 

and to be honest i dont think my head gaskets been f**ked for that long, so would it even have time to warp ?

 

can liners turn ? because mine look like they have, dunno if thats a problem or not

You do seriously need to check wether the head is warped before you rebuild the engine, or your just wasting your time. Find a straight edge - a metal ruler/large set square etc and place it from corner to corner across the face of the head. Then try to slip a feeler guage between the straight edge and the head, if you can get a feeler guage under it then its warped, youlll have to check what the tolerance is i think it maybe 0.03thou?? If you can fit a bigger feeler guage under than the tolerance youll need it skimming.

 

Rebuild it without skiming the head, and if its warped, itll soon blow again.

 

hope that helps

i got a feeler gauge in of 0.18mm, the tolerance is 0.05mm :unsure: so i'll have to get it skimmed.. i did used a 2 foot aluminium ruler so i dont know how accurate these are, not too sure if the stainless steel rullers are better..

Your best to get it skimmed then mate just to make sure. My head had warped by over 0.6 thou :) so looks like you got yours early. Anything with a nice straight level edge will do the job, but weve got a 3 foot long set square which works beautifully and is fairly cheap.
