I have not found a store opened to buy a suitable Oil Seal. But last the company visit, I get something similar (functionally similar).
The Viton washer between two metal washers https://plus.google.com/photos/11282...18205146693954
The drip test is ok. The test lasted only five seconds, the seat is unrectified.
I also did a restrictor.

Disc thermostat is ready to use -- can be used a oil seal . If oil seal material is Viton when they are equipped with stainless steel springs . Active side is rear bevel .

The price of a oil seal with Viton is below a pound.

You can even modify thermostat wax element and change its opening temperature. I used dubbin wax when overhauling a discontinued thermostat for a Crescent outboard. Has since performed fine for 8 years.

Thermostat for Kangoo I with F9Q 790 engine has rubber disc and seals 100%. Also very easy to replace wax element on this thermostat.

Dacia Logan thermostats original rubber the thaler . For Logan 1 as the Smart thermostat is . Termostat thaler rubber has Freelander 2.0 diesel, but to oil cooler (no. Thermostat PBM100040).
Complementing to the main thermostat, the system can be introduced and heating thermostat matrix . The problem is that I have not found one to 50 Celsius but I know where to use : construction machinery, karts and ATV / quad.
For the construction machinery are too high.
For the karts are too small.
The ATV / quad are suitable but I'm looking for ...
I know the 60C (at Loncin, Bashan, Kinroad ,etc ... made in China) but this thermostat should be located for easy access (at Smart?) and in the front, away from the engine.

Easy to check if seat is perfectly true. Place a round metal disc against seat and you will see gaps. My Gates thermostat had 0.25 mm gap. Fixed after 10 minutes of lapping in seat with special tool seen in one of my previous posts.

So not reclosing the lid, understand . Material deformation caused cooling ?
There is a company here (Cluj Napoca) to produce custom rubber parts . I see if it working and for Viton .

Plastic mouldings always deform a wee bit.

The seat deformed of production or the closure of thermostat housing?
Viton?From this material is sealed the hydraulic cylinders are made. Wahler thermostats were the main valve from VIT. (e.g. VW Touareg 2004) .

Seat lapping tool:


Use valve grinding paste and stick with suction cup to lap in seat. Just like lapping in valves.
