is there any way of tellin if they are 2wd or 4x4 ones
as they are in the car,the heads coming of soon and want to know if poss
the cars a 2wd but theres no slap,telling me they could be 4x4 ones

 

when did you damage your engine

 

you can tell when the head is off by the look of them.

Sure 4x4 got bigger bowls in the tops of the pistons.

they will have numbers on the edge of the pistons too telling you the size etc..

 

its not, im doin the head gasket
replacin with multilayer and was woundering,


got an oil leak from the gasket so decided to change ,along with the cam belt and other gaskets

 

so with 4x4 pistons in a 2o5 block does this alter the compression

 

only very slightly ,lower iirc

 

...if you put 4x4 pistons in a 2wd block with std thickness head i beleive you get 7.8-1 or 7.9-1 cant remember

 

whats is the head mesurement

 

have you still got the 2wd head on your car?

 

yes, its only done68k
its got a grpa(gasket) on the mo but not sure if been machined before

 

so the comp will be a bit lower then with having the 2wd head mated to 4wd pistons.

Some people get away with just changing to the steel gaskets without skimming.

depends how thick your head is,best to check that first.

 

cheers dave,see you fri all been well

 

 

Oh cool i thought you blew it up for a min

see phil your wrong again

if you have got 2wd unskimmed head and 4wd pistons the compression ratio is 7:7:1 exactly no matter if it's in a 2wd block or a 4wd block

marco

 

Was gonna say that,mine has had a tiny skim and is 7.78:1...

 

...hence why i said i cant remember..it must be nice having reyland give you info ...i was .1 out and you give me shit

 

yes but that 1 could kill an engine

and for the record you would be susprised what i know about the yb engines i have had cossys and pinto powered cars all my life

i dont need martin to tell me what i know

cossy since 92 one of the first to have level 8 and pectel board tuned cossie in the country wire ringed /grp a gasket/ standard comp / yrs ago when you was shiting in your nappy
