Tim Bell Posted May 7, 2018 Report Share Posted May 7, 2018 Need to replace Head Gasket on 1147 engine which has been boiling over (not thermostat and not radiator cap). Notice there is std head gasket and then copper ones too. Copper ones are three times the price, but are they better? Have people fitted both over time and if so, which to get?

Clive Posted May 7, 2018 Report Share Posted May 7, 2018 What brand are the non-copper? I think at least the early 1200 engines used a copper gasket from the factory, maybe all. Look for a payen gasket, usually guarantees quality. Link to comment Share on other sites More sharing options...
Tim Bell Posted May 7, 2018 Author Report Share Posted May 7, 2018 I was looking at Rimmer Bros website, but there are also a couple on Ebay. Similar price. Link to comment Share on other sites More sharing options...
Anglefire Posted May 7, 2018 Report Share Posted May 7, 2018 I got my head gasket (albeit for a Spitfire) from Paddocks. Payen- came in a complete kit of gaskets as it was nearly as cheap to do so. Link to comment Share on other sites More sharing options...
Anglefire Posted May 7, 2018 Report Share Posted May 7, 2018 Not paddocks - though I thought it was! I could have sworn it was. But seemingly not now! Link to comment Share on other sites More sharing options...

Rickoz59herald Posted May 13, 2018 Report Share Posted May 13, 2018 Hi Tim We’ve had head gasket issues with dads 948 Herald. Any head gaskets for the 948 are hard to find, so dad had been using the steel shim gasket. Gaskets still failed. Talking to a race engine builder, the head and block has to be dead flat. Even a 2 thou dip between cylinders can be a weak spot. If you plan to use a shim gasket, spray each side of the gasket with a copper gasket spray and leave to dry. Carefully torque the head up in three stages, and again after the engine has been run. I’ve found a copper gasket and hoping that it will fill any minor imperfections. I’ve been told that these need a light smear of grease to help them seat. Good luck Rick Link to comment Share on other sites More sharing options...
