I've been waiting for John or somebody over at Accufab to talk about ther new product but I guess they are just shy. This isn't meant to be a plug for John as much as a word of caution to the community.
First this has not happened to me or anyone I know of... but I heard that John at Accufab had seen a few cars, then a few more, that had a crushed oil filter (Including the center plastic support). Now it should be noted that if John is looking at a motor it's typically heavily modified and blowing out 1000+ hp but regardless of power, the oil filter being crushed was not a thing that made sense... even on those big hp motors. After a lot of head scratching, I think the prevailing logic was that the owners were taking the cars out, probably more often around this time of year when cold temps are setting in, these cars would be allowed to warm up according to the engine temp gauge (water temp around motor), then given a good throttling. Here is the problem, temp gauge reflects water getting warm, oil takes longer to get warm but that delay is magnified by the large dry sump reservoir. SO... the oil was still very 'thick.' The problem may be further aggravated by the amount of ethanol fuel used in the cars (or even methanol when talking to Johns customers) and the chemical affect on the plastic support structure inside the filter.
Its not going to be a common problem but something to think about as the weather gets cold (or slighter cooler for you SoCal boys). The oil filter is after the oil pump and the flow is from the outside of the filter, inward so the any crushed plastic support would be in dangerous proximity to the internal oils "squirters" (I think that's the term, oil jets didn't seem right).
Accufab basically fixed the issue by making a stainless steel filter replacement. It will not be able to scrub the oil as well as a paper filter but it will likely flow much better, be reusable and hold up to just about anything on the greesy side of pure lard.
**if a mod wants to remove the link, it won't bother me. I don't know if Accufab is still a sponsor here or not. I would want my friends tell me about this item and the related issue and that's is genuinely my only motivation here.
cheers
