[Healeys] texas cooler

[Andy Thorp]

The PO of my car inadvertently ruined the engine in 2000 miles by using the original oil filter. The bypass valve in the filter head was stuck open with crud which effectively eliminated the filter from the system and scored all the bearings.

Re the first start no oil pressure problem with a spin-on filter-  the drain back valve flap takes a few psi to push it open and a dry oil pump can't make any pressure. Just unwind the filter a couple of turns and crank it for a few seconds to let the air out, then you are in business.

Pic attached of a spin on filter fitted into the original housing to get around the problems of the old filter without the ugliness of the spin on ones. 

Andy.

 This subject interests me
 because I find my engine's oil pressure takes a little
 longer than I would like to come up, when cold. I
 haven't timed it, so it's just an impression. I have
 the original canister type filter arrangement.Having said
 that, it's always full of oil when I change it.

 Prior to the rebuild I had installed an oil filter
 conversion which worked just fine.  After rebuild, we could
 not raise oil pressure (yes, the spin on was replaced
 correctly) after trying numerous times.  Replaced the spin
 on conversion with the original unit and instantly got
 pressure.
