Rodbr Posted March 11, 2019 Report Share Posted March 11, 2019 I have in the past used Klingersil material to make gasket I have recently made one for an early thermostat housing I restored. It is extremely hard if you have surfaces that can not be flattened sufficiently. e.g where thermostat seats in housing. Can someone suggest an alternative that has slightly more give? I need to make another for my early thermostat Silicone RTV types etc are not an option. Rod Quote Link to post Share on other sites
Lebro Posted March 11, 2019 Report Share Posted March 11, 2019 (edited) How about cork gasket material e.g. https://www.ebay.co.uk/itm/Cork-Rubber-sheet-Gasket-material-Nitrile-Bonded-250mm-x-100mm-1-5mm-3mm-6mm/222515655251?

roger murray-evans Posted March 11, 2019 Report Share Posted March 11, 2019 Rod, I'm with Bob. Made all new gaskets for my early thermostat housing using 3mm nitrile cork sheet. Can't give you any warranty as havn't started the engine up wet yet. Roger M-E Quote Link to post Share on other sites
Rodbr Posted March 11, 2019 Author Report Share Posted March 11, 2019 Hi Roger/Bob, ordered some from a different supplier as that one was out of stock. Roger, What was the status of your of your top plate? They always seem to be quite heavily pitted and an open gasket allows contact directly with the surface. I'm going to try a full gasket bonded to the plate in an effort to make it last as long as possible. What was your sender bulb area like as I have gone for an adapter to allow for later removal should it be necessary, the threads and chamfer were a bit iffy to create a good seal.

roger murray-evans Posted March 11, 2019 Report Share Posted March 11, 2019 Rod, My top plate was in great condition.I've cleaned/primed/painted it. If it ever perforates, I'll probably reproduce in stainless and paint it. My guage take off is OK, but I shall be cautious, and do as you, with a brass adapter.

Z320 Posted March 11, 2019 Report Share Posted March 11, 2019 Hi, I use cardboard from a simple writing pad for this, slightly put some grease on it and let it lay some days aside. Ciao, Marco Quote Link to post Share on other sites
Geko Posted March 11, 2019 Report Share Posted March 11, 2019 If someone can give me compelling reasons for not using silicone gasket maker for this sort of application, i'm all ears Quote Link to post Share on other sites
Rodbr Posted March 12, 2019 Author Report Share Posted March 12, 2019 Hi Geko, Do you mean apart from the the excess squished out internally blocking the thermostat, water gallery, getting in water pump seal. I'll stick with gasket material until someone demonstrates that it is a viable alternative that you can accurately monitor the excess. Use it on engine seals and run the risk of blocking an oilway at your peril !! I agree with you Marko and this method has been used for 50 years plus but in this case I need a thicker than normal gasket. Rod Quote Link to post Share on other sites
Waldi Posted March 12, 2019 Report Share Posted March 12, 2019 Rod, goingback to your original issue: why do you not flatten the aluminium thermostat house on a flat plate with sanding paper? My housing gasket face was also warped a bit and 5 mins of sanding made i nice and flat. If the gap between housing and pump house is smaller than say 0.05 to 0.1 mm, a standard gasket will suffice. Bolt the therm housing without the gasket and measure the gap with a feeler gauge. Waldi Quote Link to post Share on other sites
Rodbr Posted March 12, 2019 Author Report Share Posted March 12, 2019 Done that. The issue is the recess for the thermostat which has been eaten away and flatting the faces has only reduces the clearance. The raised lip on the Thermostat should sit flush with the surface of the housing. i am reluctant to grind further material away to allow lowering of the thermostat., hence the thicker gasket.
