Can anyone tell me how you remove the Cyl head nuts from a Cosworth engine with a Stud and nut conversion done on it?

Nuts are 19mm and having real problems getting a socket through the holes on the head to slacken them off.

Have had 2 sockets (good qaulity impact ones) machined down to fit but they just keep splitting seems to be when the nut loosens for a start that they split

Dont think i can afford to keep buying sockets, the man in the van will be retiring shortly at this rate

Any info much appreciated

Cheers

Same way as you mate. Ground down socket, although from memory i am almost certain teh nuts are 18mm?

ARP Stud and nuts arent that big on mine IIRC. Cant remember the size, but on mine, I used a 3/8 drive socket with an adapter up to a 1/2 drive bar.

Cowboi

just a thought here. but maybe the impact sockets are made from material that dont take well to being ground down.

how about trying a decent quality normal socket.

worth double checking the size of it aswell just in case

I do it same way as JJ for my ARPs on the YB, small socket set so it fits, then an adaptor.

sounds a lot more familiar than all this 19mm stuff mate yes, im sure mine werent that big, and they were definately double hex on mine.

Thanks for the response guys

Nice to know that i am not missing something obvious

definitely six sided nuts as i have 3 of them off but £uck me thats a socket per nut

2x impact ones and a standard Chrome one (which split without even moving the nut)

Guess i'll just have to persevere.
