Started the service this past Friday as its winter time and the car is up on jack stands. I got all the belts replaced and plan on doing the spark plugs, distributor cap & rotors, fuel filter, air filter, and some other odds and ends. Just wanted to say this is a great forum for help and the DIY's posted on p-car and pcarworkshop are great and easy to follow.

Have fun with those plugs. 11 of them are simple.

Good deal, Andy! While you're in there, you may want to take a good close look at the plug wires, especially around the lower plugs. Cracks are common at this age/mileage. So if you're doing plugs anyway, replace the wires as well if you have lots of cracking, especially cracking deeper than the outer insulation. BUT, the wires are pricey!! If you don't find cracks, check em again in 30K when you replace plugs again. Have fun

I just completed all of those items a couple weeks ago with help from rennlist and pcarworkshop. It could not have gone much smoother with these great resources. You might also want to replace the SAI valve while you are in there. My biggest obstacle was the lower bolt on the rear muffler bracket (discussed on pcarworkshop). I almost stripped it and it would be a major pain in the **** to fix if I had. I would recommend removing the top bolt first and then 'rock' the bracket to help break loose the lower bolt. It will make sense when you see it.

Don't forget to replace the cabin filters and cleaning the ISV.

Good luck let us knoew how it works out.

On the lower bolt for the muffler bracket use a in line type wrench to break it loose. Space is tight so you might want to use an inline type of wrench that's thinner, my Sears craftsman works fine for this application.

The 12th plug is not that hard...just be patient and it will all work out!

i thought that the SAI valve was only on '96+ 993's? I have a '95, so does this apply to me?

Andy,

There is also a SAI valve and a air pump on the 95s. The good news is that even if it fails it will not set off any CEL, the bad news is that you have no idea if it is even working or not since it will not set off the CEL. If the SAI valve fails the exhaust gas blows backwards upstream hopefully the check valve above the SAI valve will do it's job to block it, but if that fails the hot exhaust gas will blow back to the air pump, and pretty much ruins the pump.

The hardest part on the 12th plug is not to strip the allen bolts that holds the engine shourd. Use a long allen socket type tool, due to the lack of head room space if you use a short allen socket it will not seat on the allen bolt properly and for sure you will strip it.

Tell me about it. It was a real Bi**h Robin gives a good advice re: long allen socket - see my woes on pcarworkshop! The lower bolt holding the bracket was also a pain as well - had to remove the heat exchangers.

If his '95 is an early production version, it may well not have an air pump and SAI. For his sake, let's hope that's the case.
