Hey guys, has anyone tried to test the compression of their R56 MCS/JCW?

I just bought a compression tester, and have since discovered that our spark plugs are not the traditional M14 and M18 thread sizes, and by having a look at some knowledgeable poster's threads, that our spark plugs are M12x1.25.

Does anyone make an adaptor from M18/M14 to M12x1.25? I've rung loads of people with no luck at all. They would also have to be able to ship to Australia.

Thanks in advance,

Elie

 

Try snap on tool guy. I bet their compression testing kit for like $250 has it =p

 

I tried them already, they can't help me :S

Thanks though

 

Wow. I'm disappointed in them

 

The snap on or matco kit comes with the proper adapters I have two one here at the shop and one at the house. just an FYI a healthy N12 or N14 should have around 175 to 180 psi of compression.

 

Thing is, I don't want to buy a new kit, as I already have a tester. But thanks for the specs

 

Proved me right. Thanks lol. I felt stupid for a second

 

I'm not saying you were wrong, I was just saying that Snap-on didn't want to sell me anything separately

 

Do you have a harbor freight or northern tool in Austrailia. if so try there
