I put the pressure tester on the car at 7:00am this morning at 14 psi.
It dropped to about 11 psi in about 10 hours. Hum!
Don't know if this is normal or not.
One thing I know though, I'm not 100% sure the tester itself is leak free. The cap, the hose, the gauge, the pump...
I removed the spark plugs tonight and look in every cylinder with my camera.
Didn't see anything beside carbon build-up and a drop of oil (I think) in cylinder #8.
That's good.
Here's two of them.
And all spark plugs look quite the same. Very good I think.
I put them on the car this spring. I did maybe 1000 miles since.
Let me know what you think.
I removed the thermostat and will test it tomorrow.

If it tests good, I'll get to the pump.
Thanks.
Not to get off the subject, i became nervous when I first took a look at my sparkplugs, the insulators were white like yours, is this NORMAL? most plugs I have pulled from cars and bikes have been tan in colour, which is what I have been educated that they should be.
+1. When my head gasket failed on my 84, the associated spark plug looked steam cleaned. To quote Sesame Street, it was clear that "one was not like the others."
If it was me, considering the condition of your plugs, no oil in your coolant, no coolant in your oil, no white smoke, etc., I'd move on to the T-stat--remove it and throw it in hot water to see if it does its thing.
The thermostat is removed and will test it today at the job.
When I removed the first plug, I freaked out because it was that nice (white isolator). I thought "that's it".
But after removing the second one, then the third one, etc., I told to myself that I could not have a blown head gasket on every cylinder!
I'm also curious to know why they're that nice. The ones I removed before were not that nice. They were all black.
Few things come to my mind on this:
- Of course they only have 1000 miles or so.
- Maybe when it overheated, it cleaned the isolator.
- With the old plugs, the car had a 75 degree thermostat. I put a 83 degree one last year. The car is definitely running warmer with the 83.
Which is a good thing. With the 75, it was most of the time right after the first white line on the gauge. It even stayed under the first line on an entire trip with outside temperature of about 2 degree C! Now, it's always right before the second white line.
I think that with the 75 degree thermostat, it was running too rich most of the time. But that's me...
Anyway, if the thermostat tests good, I'll get to the pump.
Curious to see the coupler...
I would suggest you replace,
the thermostat, inner rear seal and O ring,
heater control valve and short hose,
coolant cap and water pump and timing belt.
Why ?
all of these parts will be in service for the next 6 years or more,
no sense in putting used parts back in now.
JMHO
One has to wonder if a 75C thermostat is better then why would Porsche not fit such? The fan programming is not designed for this and when I tried a 75C thermostat it seemed as though some funny things happened during our cooler months when the cooling system was not really challenged and I chose to run with the a/c turned off.
Ditched that thing and I run with the stock thermostat.
Hopefully Bertrand will get to the bottom of his issue quickly whatever the cause- just goes t show that no matter how well one looks after these things they wil always have a tendency to find some way to bite you in the *** [or the wallet]!
When I did my water bridge I replaced everything. i never really paid any attention to the temp marked on the new thermostat. That said my car's indicator is just right of the last white indicator line (as is normal). But there is only 2mm of distance before the indicator hits the red...and that I don't like. I wish the engine ran a little cooler and the indicator was closer to the middle of the gauge.
I changed my spark plugs this spring. With the old plugs, the car had a 75 degree thermostat until last year when I put a 83 degree. The car is definitely running warmer with the 83 degree.
Which is I think a good thing. Where it's designed to run. With the 75, it was most of the time right after the first white line on the gauge. It even stayed under the first line on an entire trip with an outside temperature of about 2 degree C! Now, it's always right before the second white line.
I think that with the 75 degree thermostat, the car was running too rich most of the time. Not 100% sure on this but...
I never found anywhere a good reason to put a 75 degree thermostat.
If I remember well, I thought, like you say, that it would be a good thing to do so.
Now, I don't think it was a very good idea...
