Hi ,i am still using coolant.car runs great.No smoke,no water in oil,trany ect..
Just uses about i quart of water every 50-100 miles..runs at perfect temp. Pulled plugs ,they all look normal.I think my intake must have a leak.
I am scared to pull it off because of the bad wiring on these cars.It has a new harness but o.e. electronic throttle and wire that is part of the it.
=====Has anyone had intake problems on this 94-E420 motor.=====
Strange never runs hot,seems to be normal coolant pressure and any thing i could fix i did.
I work with cars and found some hc's in coolant bottle.But that can still be intake.This has been going on for months but gets a little worse each few weeks
Lost
