Nothing needed but a wash and spray detail. And a ride to the mountains where its only 85°.    

Although I am a little troubled that my new timing belt still whines a lot. Last time I had it done the mechanic told me Its normal for them to make a little noise when theyre cold. Its when they dont that you have to worry. It gets quieter when it warms up, but it never goes away. Im coming up on my 1500 mile check and re-tension, so Im going back to my regular guy down in Las Vegas.

Timing belt is a non-tension item due to the hydraulic tensioner on the motor doing the work. It is the balance shaft belt that has to be manually adjusted after a couple thousand miles.

Gotcha. As long as the timing belt was properly tensioned in the first place. Given the quality of the shops work, I have my doubts.



(My serpentine belt was so loose it squeeled like a banshee when I started it up)

Then again, it might be my own damn fault. It had been 6 years, but only 7,000 miles since my last belt service so, like an idiot, I only replaced one pulley that was a little iffy.

On our cars you cannot get the timing belt tension wrong, they never make a noise, its always the balance belt that whines, and always because they are to tight

Waylander is correct - the timing belt is kept under constant, correct tension by, well, the timing belt tensioner.  The only way the timing belt's tension could be off would be if the tensioner failed somehow.

 

Getting the balance shaft tension just right is a tricky operation.  It needs to be looser than appears reasonable to prevent it from whining, but you have to be very careful to get the clearance between the belt and the roller above it just right - if the gap is too large, particularly if the belt is on the loose side, you risk skipping teeth on the belt.  And of course, changing the gap also impacts the tension, so getting everything right involves a lot of iteration, which can get very time-consuming.  I've done the job many times, yet I always dread it.

I have a feeling that it was the first time the shop had ever done one. Locally famous Porsche shop, but deals with 911s and 356s. I was a fool to let them do it.

At least re-tensioning the belt doesn't involve much disassembly - just a lot of patience.

dl476, I have done the same thing and ended up with a mess. 911 and 356 are different vehicles then 968,s

Washed the 968 today.  Then clay bar, then polish, then ceramic shiny finish.   Car looks great.  I’m beat!

Blue clay bar from Amazon.   Some leftover Chemical Guys lubricant, ran out, made my own (dish soap & water @16 to 1).  Sonax Profiline Perfect Finish, Turtle Wax ICE Seal N Shine Hybrid Sealant Spray Wax.  Don’t know if it’s the best, I kind of checked reviews on Youtube and Amazon.

So it wasn’t a ceramic based product?

It’s a hybrid of wax and ceramic coating properties, whatever that means.

I use the griots product and was very pleased with it.

Had it smog tested today .  Unlike other states , Kaliforniastan still requires all cars newer than 1976 to be tested, and there is nothing on the table indicating this will ever change anytime soon ..

So I took it to a place which is a major foreign high-end automobiles service  shop, which also does emissions tests.   My friend just had his Ferrari smog tested there last week .   So what’s the point of this post you ask ?   I’ll tell you :  every single technician in that shop came over to gawk at the car close up, in total admiration ..comments poured in.  Several  said it’s one of the nicest automobiles they’ve  seen,  many were surprised by the like-new shape of the paint after nearly 30 years , while most were blown away by seeing the supercharger and then realizing it’s CARB certified.     Nice affirmation of this great car !! 

p.s. passed the test ( easily ) as usual .  Even though I wasn’t sure the secondary air  system would be ready since I only drove it for about five minutes to the shop, after sitting still in the garage for about three weeks, But it was perfectly fine .

After a friend attended a PCA tech night put on by The Rag Company, I bought some Opticoat No Rinse car wash and their HyperCoat ceramic coating. After doing the ONR, I decided I should clay bar it before I coated it, so I did. Likewise Amazon clay bars, 2/$10.  

 

The ONR was pretty slick (pun intended) but attracted dust like crazy. When the HyperCoat finally got here, I ONR’d it again and did the coating. Couldn’t have been easier. Spray it on, rub it around, buff it off. 

 

btw: I’ve washed my car more in the last week than I have in the last three years. 



After ONR, pre-clay bar:

   

post clay bar and HyperSeal. 

   

 

The slight difference you can see in the pics is 10X more apparent IRL. It really brought out the deep purple in the Midnight Blue paint.

In related news, I put my pans and splitter back on today after taking them off prior to getting my belts done. Does anyone have installation instructions for a DR-1 splitter? I’ll be damned if I can remember how those little tabs go on the end pieces. 

 

As for my belts, I’ve had sufficient time to process the fiasco it became. I’m going to post it in the repairs thread tomorrow. Teaser: I came within 10-15 miles of grenading my engine. Totally my fault.

Had ours smog tested a couple days ago (in Nevada), as always no problems.



Before then, on 4/30, we took it to Luftgekuhlt (normally only for aircooled Porsches, but this year they added a second day for air or water cooled Porsches) at Mare Island (Vallejo, CA). It was a very good day.



When we arrived, there was a special area for those that showed up in a Porsche. And, after we parked and were walking about 100 ft to have our tickets scanned, already a couple people were looking over the 968.



The night before we attended a BBQ (arriving in the 968) with a 914 (Air Cooled Porsche) Bay Area, CA crowd. Again she got lots of attention



My contention is that due to the very limited production added to the fact that few Cabriolets were imported to the USA (only 2,008 imported to North America), many just don't know about them. Also, now that she's about 30 years old, there are lots of younger drivers that missed out on the opportunity of seeing or getting one from a dealer showroom.
