cracked em?
 

just bought a non running 93 fd

got it running, sounds like a tractor and the engine compartment is full of fumes,

havent found the source of the leak yet but is a crack in the manifold the probable cause?

cheers
will

A little more info is good... External exhaust leak or just the sound and a weird lope? external leaks are usually ok easy to locate if nothings bad(gaskets/manifolds) then a stuck corner seal?

def leaking, think oil metering pump has a fault on it so dosent run very well either,

basicly what has happened is

car has been imported from japan so has been sat on a boat for 3months

then it has been sat in a yard for 4 months

a bloke buys is not really knowing much about them and thinks the rotors gone on it so starts to take it apart. He describes the fault as no power, and back fires when rev'ed which to me sounds like its in a safe mode due to something such as low oil metering pump pressure

i buy if off the bloke half stripped

put it back together and it sounds like the manifold isnt even connected, (ive checked it is)

heard a while ago manifolds are prone to cracking will strip down again this weekend.

car is standard by the way

how do you diagnose a stuck corner seal?

If the oil metering pump is bad, this will cause the car to go into limp mode.
