    Posted: 06 May 2022 at 2:04pm
My 7020 has started leaking antifreeze/coolant from around one of the injectors. Ive tried tightening the two bolts holding it in with no change. Wondering if the olives at the top of the injector work as a seal and a dust cover?
The tractor has no white smoke. No overheating. No milky engine oil but it does bellow out black smoke if under pressure? Wonderiging if its a bad injector or head gasket Or the pre cups?
Any help is much appreciated

head removal. I'd be trying some ceramic seal to seal it up.
