I have just bought a 2.0 zetec engine for the capri to transplant in with everything to go in!
but my problem is. i currently have a full tank of fuel with lead replacement juice in it (as the old pinto aint an unleaded engine)
would it be better to run this through the engine till the tanks nearenough empty and whack as much unleaded in as i can to dilute it as much as possible before the zetec goes in
or will it not do any harm to the newer engine, just make it run a little craply for a while as it runs through to pure unleaded??

 

no problem - would only kill the cat. if it had one

 

And lambda sensor - so remove this if it has one until tank is empty.

 

thank god youtold me that one!!! them things are a cow to get off the manifold and replace!

although... i wont be runnin a cat... and will be running weber alpha management system with DCOE's... so it might not even have a lambada to worry about?

 

doh! forgot about the lambda sensor nice one mike

 

probably easier then to run the capri til its empty, drain out whatever is left and fill it with fresh unleaded
