"The lock washer is flimsy and too large for the head of the bolt causing said washer to split apart and fall off if a person puts any decent torque at all on the bolt."
"Says it fits a 2000 Corvette (LS1, only 1 option for the engine) and it is soooo much smaller than the original bolt."
"Lock washer cheap and spread apart at proper tq."

Best Automotive Performance Engine Oil Drain Plugs

Fumoto F-106N Engine Oil Drain Valve
Incorporating Fumoto's most compact ball valve, Fumoto's FN series valves are designed to fit cars, light trucks, vans and select commercial engines. Ideal for drawing small sample of oil for oil analysis.
Reviews
"I put one on my old car back in 2008 and after 207,000 miles, I got rid of the car and sadly my Fumoto went with it. I loved the one on my old car so much, I bought this one for my new car. - No Mess - Putting a hose on the end made it easy to direct the oil into the oil catch container."
"The lever is designed spring loaded and keyed so it can't simply swing open and start dumping oil. Attaching a hose prevents splashing of scolding hot engine oil."
"On the 2001 Suburban [with a 5.3 liter V8], the threads on the oil drain required adding an extra gasket so the Qwik Valve would be oriented with it's release tab away from the ground. [see pics for right and wrong orientations; pix are from a '95 Saab 9000 Aero] If you prefer a longer, brass adapter for the Suburban, there is one available: Fumoto Valve Adapter ADP-107 (12mm-1.75) The Quik Valve folks are aware of potential issues with low ground clearance, especially if you're off-roading or four wheeling, so they do sell a clip that provides an extra measure of 'lock' on the tab to keep it from pivoting open if you snag a branch, etc. You simply reach the small locking tab, pivot it up slightly, then rotate it toward the drain port [approx 90 degrees] and the oil will flow. This is not a factor with the QuikValve fitting: when you rotate the tab, the brass and stainless steel sleeve pivots [looks like it's inside a nylon bushing] to open a good sized hole, approx 5/16"."
"I did my first oil change yesterday since i installed the valve and wow it made my whole process so much faster and easy!"
"To general a fit, should be model specific because of oil pan clearances."
"I had the last oil change service install it instead of putting the plug back in."
"Perfect for diy oil changes such as myself."
"This drain valve makes oil changes cleaner."

Best Automotive Performance Engine Main Bolts & Studs

ARP 2504202 Stud Kit
Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned, something that won't happen with inferior quality head studs. ARP studs are thread rolled after heat treat, which gives them about 1000 Percent (that's ten times) better fatigue strength than those studs that are threaded prior to heat treat. This procedure (done only to the shorter studs) more equalizes the "stretch" of both studs, which makes for a more consistent clamping force and one that compensates for head gasket compression when the cylinder heads are installed. Thread Rolled After Heat Treat, Which Gives Them About Ten Times Better Fatigue Strength Than Those Studs That Are Threaded Prior To Heat Treat.
Reviews
"With the problems that plague the Ford 6.0L diesel power plant, when it came time to repair the inevitable head gasket failure, installing these ARP head studs was an absolute necessity."
"This product is the reason why many of the 6.0L trucks are still on the road."
"I did remove cab and heads and had the heads checked."
"A must for the Powerstroke 6.0."
