Technical Headgasket change question

[LanciaMad]

How important is it to skim the head when changing the gasket?

Anyone done it without skimming?

To do the job properly, skim it.

It will fail again quickly if you don't.

What about if its not failed and changing it as a precaution?

Still skim it. Very false economy not to, and gives a perfect mating face, which is, of course entirely different to a 'cum face'.

Ok, thanks

always skim the head if you have the engine out skim the block too

No point in skimming the block. Just make sure it's as clean as clean can be.

Always the best option is to have the head skimmed, just had one done for £30 at a local engineering place

how much should be skimmed off the head?

 

[arc]

the min amount to make it flat

Skimming the head will make it perfectly flat again or near enough and ensure that there is a tight fit between the new gasket and the head.

Your engineering shop wiill take a wee bit at a time off the head until they get to a flat surface.

just for the record i didnt get the head skimmed, just cleaned it as much as i could. Cars fine so far, will let yous know when it next goes like.

 

[LanciaMad]

6 months on and still going strong

i never skimmed mine think its only neccisary if it overheats and warps slightly?? i could be wrong and when i do my next engine i will skim it so i ensure its reliability
