OK... question here... and something for people to contemplate.... People speak frequently of low pressure in Triumph 4 and 6 cyl engines. This too has been bugging me... trying to understand why the pressure would drop so much just from the engine warming up. Some people say it's the oil and a zillion conversations have come up concerning which oil to use. BUT...if that were the main reason it would hold true of other LBC's which I've found not to be true. That is...at least from my own personal observations.... the pressure doesn't drop as much in any other LBC I've owned.
So....after MANY hours of thinking about possible causes.... I pose this question/consideration. Most (newer anyway?) oil pumps for these engines use a steel center star wheel, but an aluminum body for the oil pump. Considering the differences in the expansion coefficients of these two metals.... doesn't it seem quite feasible that that the body to star gear clearances are opening up thus reducing the pressure the pump is capable of producing??? hhmmmm...... the more I think about it...the more it makes sense! Anyone know if anyone still produces a steel bodied pump?!!! Paul Tegler [EMAIL PROTECTED] www.teglerizer.com *** http://www.team.net/the-local *** Your messages not reaching the list?
