TCA Tech Tip of the Month

GREAT OIL FILTER TIP - BEWARE!

The good oil filters that we are used to getting at our local Peps Boys may be lost and gone forever. Whenever I go in the store I always check to see if they have Corvair oil filters available and if they do, which is quite often, I snatch up a few for my supply shelf. Purolator has been the brand that I have been buying and using successfully for years. I recently discovered that they have changed their design and, as usual, the new one does not work very well, if at all.
The outer seal design has been changed from an inserted rubber seal to a donut-looking seal that slips around the outer edge of the filter housing. “No harm, no foul”, you say? Well, According to JR Read, a fellow Virtual Vair member, the new outer seal is so thick that it does not allow the inner seal to fully seat into the oil filter housing, thereby allowing oil to bypass the filter altogether. JR went to the trouble of cross-sectioning one of the castings and mounting a new filter on it to prove his point. The old ones came in a white box and the new design comes in a blue box.
