I will support the "Some do/Some don't"
FOr example I had a job done twice this Spring. I blew an exhaust manifold to exhaust pipe gasket. AKA Donut.
In VA I went to a Multi-vehicle service center. Took 'em like 4 hours due to a stud with stripped threads. Where as I could have had that stud out of there in under 20 minutes easily (YES I am qualified to do that work though not licensed, Just don't care to roll around in the dirt doing it Mechanic had nice clean shop floor to roll on) it took him 4 hours.
600 bucks and that was Friday Afternoon.. Mondy morning the el-cheapo aspbestos I assume gasket was once again HISTORY.
Got back to MI (I had it replaced in VA because where i was going at the time Id never gone before so Lola was my guide (GPS) and I can't hear her going up hill in the mountains with that donut gone.. I can't hear myself THINK with that gasket gone
when it went the 2nd time I was on roads I've traveled before with a printed guide so I did not need LOLA's voice)
The mechanic took one hour (Minimum billing) and used a Sintered Metal Gasket.. May well outlast me .
When I say I could have had that stud out in 20 ninutes....H
The one and only NEW car I ever owned came with a Sintered metal gasket (International Harvestor calls them a Fire Ring by the way it fits a SCOUT and though I did not have a SCOUT same exact part as it happens)
Well it had no "Retainer" so it slid out over time and I had to replace it.. Finally I could not get one so I put in an aspbestous gasket (The car maker was expermenting with teh Metal gasket and .. Well they had a lot of complaints I gather) The fiber gasket lasted less than a week. So after a couple of those (I got real good at replacing them) I got ahold of the maker (I only lived a few miles from their HQ) and a warehouseman who recalled the name of the supplier.. A specality metal company
Called them and they gave me the International Harvester part number
Well the nice thing about living in Detroit is LOTS and LOTS of automative/truck dealers so I visited teh IHC dealer in Dearborn. Got a pair of "Fire Rings"
Modified one so I could use the retainer ring from the fiber ring.
lasted till the exhaust rusted out (Many years)
YES. As I said. I know how to do this stuff.. Of course one stud broke on the car so I had to drill it out and put in a bolt.. So i even know how to do that and 4 hours there is no excuse for.
But some shops do a good and honest job..
Was chatting with some fellow customers of my favorite Mobile RV tech yesterday She's the RV GIRL (Well that's her license plate) And I told of our first meeting..
She installed a Trac Bar on this rig.
First she spread a tarp so she did not have to lay on rocks (Can't say as I blame her)
Then she spread out and READ the step by step instructions... WHY I like her more than many men SHE read the instructions
. She was smiling at that one.
She's also cheaper by 15 dollars than the shop I go to and they are the cheapest shop in the area.
(THey make it up on volume) but Racheal does not do engine work.
She was fixing their plumbing
And I'm having her re-caulk (routine) my roof. She bends better than I do.
