Yesterday I decided to tackle that !!!error: Indecipherable SUB-paragraph formatting!!! I have, and here’s the rundown:
Obtain new gasket via mail order
Need to remove exhaust manifold to replace gasket
Need to remove upper heat shield to access manifold
need to remove airbox to remove upper heat shield
need to remove cruise control vacuum servo to remove airbox
Yay, woo! now I can unbolt the manifold. I do this.
Next, I give it a yank, and it doesn’t give, so:
Need to remove downpipe flange bolts to remove manifold
Notice mickey-mouse hose clamp “repairs” from previous owner to settle down rattling heat shield.
Bolts are off, manifold still won’t budge
Maybe need to remove midpipe to allow flex at the flange?
Downpipe is bolted to the crankcase
So I start working the nut I can see on the downpipe bracket, and after realizing I just rounded it, I see that it’s welded to the bracket .
Also notice broken welds on joints between downpipe heat shield and pipe itself
Assume previous owner had tried welding the rattling heat shield in addtion to hose clamping it
Start cursing him for amateurish repairs
Contemplate removing other side of bracket, the part that is bolted to the crankcase
Realize this will open the engine/transmission gasket
I’m not ready for this
I need to drive to work tomorrow
And therefore, for only the second time in my shadetree mechanic career, I gave up and reassembled everything.
So, then I went to bed, and took the workshop manual with me for some light reading.
Notice the nut I was trying to take off is merely a captive nut (welded at the factory, duh) and the bolt which is intended to be removed is accessible on the other side of the downpipe .
