brian-nz Posted February 19, 2017 Report Share Posted February 19, 2017 Hi All There was a recent thread which I cannot now find. I too have an oil leak around the oil filter. Before replacing the oil filter I tightened the nut holding the spin on adapter. This was loose and oil leak fixed there, however another leak has developed or likely to have been there all along. It appears to be coming from the gasket between the engine and oil filter head. Can just undo the bolts holding it to the engine and take out as one unit and replace the gasket or is it not as simple as that? Regards Brian Quote Link to post Share on other sites
foster461 Posted February 20, 2017 Report Share Posted February 20, 2017 Cant think of any major issues Brian. The oil pressure line banjo needs a couple of copper washers so it may be prudent to replace those too as you will have to disturb that connection to get the unit off the engine.

monty Posted February 20, 2017 Report Share Posted February 20, 2017 If it is a spin-on conversion then the most likely cause is a leak between the head unit & adaptor. There is an o ring between the two & I have always had a problem getting a decent seal. Quote Link to post Share on other sites
brian-nz Posted February 21, 2017 Author Report Share Posted February 21, 2017 Thanks guys Took the unit off yesterday and the gasket was hard and brittle and can see why it wasn't holding in the oil. Also one of the bolts was stripped which wouldn't help. Have made up a new gasket and will put back together later in the week. I had previously tightened the spin on adapter so should not leak there anymore. Will I need to undo the pipe at the gauge end to pump oil up to it Regards Brian Quote Link to post Share on other sites

Having air in the oil pipe can have a beneficial effect. The air acts as a damper and stops the needle bouncing around should there be any pulsing in the oil supply. As for normal operation, the oil will quickly compress the air and it will work fine. Roger Quote Link to post Share on other sites

Hamish Posted February 21, 2017 Report Share Posted February 21, 2017 Agreed 100psi in any medium is 100psi. It's when you mix the medium in the same system you don't want squishy soft air in your brake system ???? Quote Link to post Share on other sites
