    Joe Gibbs Racing Oil

    I watched a back to back comparison with penzoil 25-50 on the dyno , then with the gibbs break in oil, then the #6 syn race oil. This was done in a 410 sprint car engine that was brand new and never raced before. I also feel it was done in the correct ways to be 100% on the up and up. The gibbs...

    Dirt racer's engine goes up in smoke........

    It ran 13 races.. any issues like that would likely have surfaced long before that. 44H

    Dirt racer's engine goes up in smoke........

    If you had a magneto issue as you stated and #8 was the one burning colder, my guess is that you likely hydro locked that cylinder at some point with fuel and it bent the rod. at that point it was a matter of time before it went boom, but without looking at things close its all speculation. 44H...

    harbor freight tools

    in tools... ya tend to get what ya pay for in most cases. Some of the Harbor freight stuff is more than adequate, on other stuff its laughable. its more or less a trial and error type thing really, I have alot of H.F. stuff but when it comes to important stuff I spend the extra few bucks, and...

    STUCK FILL PLUGS... ANY IDEAS ?

    are these the square 1/2" drive type plugs.? if so, I suggest a breaker bar/extension setup and steady constant pressure over air ratchet type load. once out obviously anti-seize and less torque is to be used. but heat around the plug and do it with the bar in place as it will act as a heat...

    Torque wrench problem

    this is straight off the craftsmen site verbatim : * If any Craftsman hand tool ever fails to give complete satisfaction, return it for free repair or replacement. doesn't seem too cloudy to me.... 44H

    Exercise Interval for Emergency Generators

    I have been in charge at several diff. companies that relied on some very very big emer. gen. and among strict maintenance and impeccable records it was almost always once a month, and no less than 60 minutes. mainly for a full heat cycle and load variation and then we also tested the main UPS...

    undercarriage rustproofing?

    they make a spray on under coating in a spray can. if ya do it yourself, I would get it as high up as possible, get the tires / wheels/ etc off . and then mask well and take your time. A new mustang isn't already undercoated..???? to some degree atleast? 44H

    Torque wrench problem

    its a craftsman.... return it. lifetime warranty, no questions asked, if in fact you wanna go that route. nostalgia is great but has no place in regards to torque wrenches in use. wall hanging , great, head bolts, not great. it is likely the engagement dog or the center gear. it could likely be...

    Could this actually work

    Thats not new technology by any means.. just in this application it is. but your water heater has had this exact same technology for a long time. it works there, logic dictates it would work anywhere almost. but is it needed..? some areas i'm sure it is, others not likely.. 44H

    Cooler line pressure drop

    Why would you have that sort of pressure drop in only 5 foot of straight tubing..? you lose flow at any bend or drastic change of direction, but if the line is not flexing under pressure, which there's no reason it should be to any sizeable amount, then other than minimal friction losses your...

    Foam filter or paper filter

    in that environment i'd definately go w/ the foam filter. they've proven themselves for better than 25 years in motocross, dez., etc. get the foam, use the right oil, and clean it properly, all things will be good. 44H

    Tire Siping

    No worries, there's plenty to be done with those from what I see. you can horizontal cut the center 2 strips every inch or so. theres no edges or grooves of any kind in the center so I see those wearing somewhat faster ., they can do quite a bit there though, it shouldnt cost all that much for...

    Uni filters

    An 89 rmx was / is a 2-stroke. I suppose you could do a OA on the tranny oil but the guy doin it may fall over when he sees whats in there. aluminum, brass, steel, likely a good amount of sand, etc... which is why we changed it out every other ride. the main bearings are separate anyway and they...
