what is this called? (the gauge looking thing not the wire that connects it). i have a leak and it needs replacing
would you be talking about the oil pressure switch? If it's leaking from the thread and the switch still functions properly, remove it, clean the thread, add some sealant and re-install.
thats the one thank you i just did exactly that now i dont have to go to the shop
its a pretty comon occurence... let us know how it goes
