FTFY mate. Good for you for being just respectable enough to teach us that taking responsibility is taking the higher road and going above and beyond.
+1.
TLDR:
OP brings car in for service, completes service and goes home
Grinding noise along the way, finds that engine splash under shield has broken due to missing hardware not being reinstalled by tech
Contacts shop and owner, back and forth etc.
Car is brought back in for a 2nd time, supposedly fixed
OP goes home again, only to find it's been fixed with some bolts, a ziptie, and another random bolt.
More back and forth
OP at least now has a new splash shield so he's going to install the bolts himself
I don't know why some of you guys are finding the faults so hard to comprehend
Must feel pretty breezy up in that ivory tower when you tell OP he should have resolved this in private. You guys know that his first post about this was way back on June 24th, right?
