Not sure what to do.
I am coming to an impasse with the Buick, and I am not sure which way to go with it.
167k miles have since come and gone since it first saw the light of day in April 1993.
Coolant leak from Throttle Body Gasket (getting worse)
Likely original Lower Intake gaskets.
Uneven firing issue that I suspect is either ignition related, or a vacuum leak,
Running a custom intake, that really is screaming for a FWI (custom rice pipe, to stock accordian, dumb, I know)
Currently getting 13mpg (stop and go probably to blame for some of that, but not all)
Prolly due for full tune up (plugs, wires, o2, etc)
Not 100% sure, but I believe the cat converter is toast.
Choice 1: Take the car to a local mechanic, pay someone to tear down the top end, replace all gaskets from the LIM on up and be done with it, and do tuneup when I can get around to it, with cat converter after that.
Pros: Car is in and out in one day, and doesn't have any real down time.
Cons: I don't get to see the process, and doesn't allow me to be as thorough as I would like to be
Choice 2: Buy a $500 beater, pull the Buick in to the back yard, and take my time on it. Replace LIM gaskets, replace vacuum lines, full tune up, maybe relocate evap canister for FWI, etc.
Pros: Car gets the TLC it deserves after almost 4 years of merciless beating from me, will probably track down the funky motor mount, etc.
Cons: Sourcing and dealing with a beater while work is being done, much more to go wrong, etc.
What should be known: This scope of work I would like done is probably something that could be done with 3 or 4 beers at a meet. I have a tendency to get frustrated after a bit, and if the car is apart, and I need to drive it the next day, that is when the stupid stuff happens, because I am rushing and frustrated. I would expect the Buick to be down for 2-4 weeks to get the level of attention I want to give it, without setting fire to it.
I have most basic tools necessary, the only thing I may need might be something related to the fuel system fittings, and I have an area I believe I can work easily in. Weather is not a factor this time of year, unless it is rainy or something.
I know this is long winded and repetitive, but I am looking for advise on which way would be best to go, or any other options overlooked. Getting kind of tired of the car as well, and don't have the love for it I once had. Not by any fault of it'* own, just want something different.
