hi to all,
i am new to this site.
haveing problems with my 1953 f-500 flathead v8 239
thinking that gas is leaking into the crankcase.
i have changed the fuel pump and filter with a off the shelf filter.
i changed the oil after changeing the fuel pump as per fuel pump instructions. i was thinking that this was a good fix,however a short time later it began to run ruff. thinking that iam getting fuel somehow leaking
into the crankcase. how is this happening? does this engine need a compleate rebuild?
i have only owned this truck for a short time, not sure of the in's and out's of the flathead v8. can you help,thank you don.
