Re: oil filters

[jtrealty@xxxx]

I have not opened a purflux filter so I can't say with certainty but 
the spring loaded valve you are refering to is the bypass valve. On 
many filters there is incorporated inside a valve so that in the event 
the filter gets too plugged up it allows the pressureized oil to 
bypass the filter. The logic is that at least oil still gets to the 
internals even though it is not filtered. The specs vary widely so in 
general it is not a good idea to stick on any filter that physicaly 
fits without knowing about the valving and ratings. IMHO the Purflux 
is not so hard to get or so expensive that it is worth the possible 
risks. If you are having trouble getting it call a Delorean vender and 
order 2 so you have an extra! For those of you who think it is too 
expensive go see what filters for Jaguars cost!
