Default My WYAIT story-update on poor running issue.

It all started when I noticed my radiator was leaking a little, passenger side near the upper hose. I figured the seal on the end tank was bad as I didn't see a crack, so I pulled the radiator, ordered a new seal and took it too a shop to have the tank popped off and back on with the new seal. He shined a light in the end tank and showed me the crack that I missed. So, I ordered a new tank.

But, I noticed that with the radiator out, there was a lot of open space under the hood and it seemed like tearing all that down for the radiator work was a good start to a motor mount job, which means an oil pan gasket job as well, which means do the steering rack bushings while i'm down there. Well, one thing led to another and here's what I've done over the last few weeks.

Solid motor mounts
Silicon oil pan gasket
Solid Delrin steering rack bushings
Synthetic motor oil
Drained tranny and diff and filled with synthetic
Replaced clutch master and slave cylinders and the blue hose
Short Shifter, shifter bushings, shifter cups
Advanced timing with Porken's 32vr
Replaced tires with Potenza RE-01R's
Touched up caliper paint


Did I miss any wyait's?

how was the clutch master a "WIAIT" operation?
How did you do it? traditional pain, or through the wheel well hole, or replace the guts from the inside? Ive never done one and might do mine some time soon.

I did my clutch master a few months ago "the hard way" and it wasn't as bad as people make it out to be. Removing the brake master makes a lot of extra room to work with.

to add to your progress you should also consider replacing the oil cooler lines , only caveat is to not remove the fittings that are screwed into the block, they will usually POP off pieces of the threads and then it may leak, just counter hold them when undoing the lines.
You can have the lines rebuilt at any good hose shop.
Also you may want to back wash the AC condenser with a hose , spray from behind and watch all of the dirt and small rocks come out

clutch mc when I was at it wasn't that bad... unbolting and not removing the brake booster was helpful when I did it on my 79. I did forget to put the clamp on the blue hose at the MC nipple.. :-( Not too bad overall. :-)

Well, the clutch master and slave weren't so much a WYAIT as a WIID (while it is down). :-)

I went the route of the hole, but I just cut a flap instead of a complete hole. It was easy to seal it back up.

I might go ahead and do the oil cooler lines as well, good suggestion.

Power steering lines leaking? That's probably the only other WYAIT that I can think of.

Oil cooler lines and PS lines are dry. There were so many other things I considered doing, drilled rotors and new pads, X-over, fote injectors, knock sensors, steering wheel, GTS or aero mirrors, porken tensioner, plenum spacers, etc, but my bank account said nuh uh. This will hold me over for a while.

if you can spin the oil cooler fitting in the end of the line it should have a new hose/crimp

Don't forget the resevior with its built in filter.

I'm tackling a similar leaking radiator and am going to also replace all of the coolant hoses, thermostat, heater control valve, expansion tank cap, ditching the air pump, brakes: rotors, pads, painting calipers, brake lines, m/c, slave, hard line, oil change, should probably do the diff oil too, hadn't thought of that, all accessory belts, tires, and a few other things I'm not remembering.

Also looking for some cheap used Sparco, Corbeau, Recaro's to gain some much needed head room.

Good to hear the clutch m/c may not be as brutal as I have heard.

Good time to clean up the engine bay and it doesn't cost anything except some rags and labor.

Also recheck the power steering hoses right below the reservoir to make sure they're not seeping. If they haven't been replaced now would be a great time to get them done since they're easily accessible. They're notorious for leaking as others have mentioned.
