it isis gunk the brand name of the product?? - excuse my ignorance, i've never heard of the stuff before joining here, but is it similar to a degreaser?
I sometimes use rubber grease, i use the red rubber grease by PBR. i think castrol makes it too, with the thermostat housing and other water fittings i use grease on the gaskets makes a water tight fit, a old man called mal, he owns an old ford zephr and an old rugby car, he told me the grease bit, i tried it myself and it works great, and if you are lucky when you need to fix something it will come apart easily and if you are more lucky you may even be able to reuse the thermo housing gasket again, or just cut another out of cardboard, if you really dont want to buy cardboard for automotive places, cereal box card board works just fine, my dads father used to use cereal box cardboard with silver frost painted on when he worked on his old post WW2 bedford logging truck, and my grandad would be around 125 years old, he died in 1975, i never knew him as he died 10 years before i was born, my mothers father would be 100years old this year he died in 1996, anyway. if i have any tips i'll let you know guys.Yesterday I put everything back in. Especially the hose between the cilinderhead and block is a crime. vaselin, dishwasherstuff, hot water; nothing really helped. so I fitted the thermostathousing on and by turning the bolts the hose eventually got in place.View attachment 101169
oh ok very interesting never knew that, yeah its a good trick.Thanks Tony, I the dutch army-service/maintanance manual for the land rover it is recommended to put grease on both sides of a new gasket. Works great indeed!
