2nd post in day seems like I'm not having much with my 75
The past few weeks the car had developed a tick on start up I thought it would be the tappets but it started getting worse it lasted longer than few seconds sometimes a couple of minutes so I bought a can of seafoam threw it in and for a day the noise did come back but today it did again this morning so I'm starting to think that perhaps it's not the tappets the noise seems to be coming from drivers side rear but I couldn't pin point it. It does come up with revs but it's more prominent on idle. Also the engine is very smooth and feels completely normal even when the tick is present which baffles me even more.
I'm going to include a video it's not the best as it's from the cabin but you can hear the sound
