Review on Dorman 917-377 Oil Dipstick for Engine by Nathan Guzman

Not a fan of this dipstick. First, it didn't work right away on my 5.3 LS engine. I had to twist the tip to get through the bends in the dipstick tube. The probe itself is very thin and bends easily. This forced me, as a last resort, to replace the damaged OEM stick that came with my newly purchased used truck. I ended up buying the factory direct from my local GM dealer for about $5 more than the aftermarket version. Do yourself a favor and buy it once from the retailer.
