I have a 1990 Honda accord ex. So I’m replacing the cam and crank seal and well I want to know if there is any other seal I need to look at or replace. Not trying to take the timing cover off to replace any seal I missed. Going to do the balance and timing belts along with the water pump since it’s definitely needed. There is definitely a leak since I found dry residue at the bottom of the timing cover and well the cam seal looks dry, imma still replace it but is there any other seals I’m missing??

 

Well, there is a front crankshaft seal, but from my experience the only real oil leak on the front of these engines is from the oil pan as well as valve cover. The valve cover s also like to leak into the spark plug holes.

With my 6 or so 90-93 accords, I have never seen a cam/crank seal leak. But they are over 30 years old. Just make sure to buy quality or you may cause a leak.

 

Yeah I got fel pro seals for both and well the valve cover did leak. Found signs of oil residue in the spark plugs holes and well 2 of the spark plugs had oil on them and when I removed the valve cover, there was oil passed the seal. I see where it could have leaked down since you see old oil coming from the cover. I just want to replace them since I’m already doing the water pump and timing belts. Also someone already loosened the crank bolt so since I don’t have a crank tool yet, might as well inspect and replace them since it sat for 8 years

 

Whoops. I forgot to mention the crank balancer shaft seal. I always forget that these Hondas have 2 timing belts... (3 seals in total under the timing cover)

 

Where would that seal be located at?! If anything imma check to see how it looks once I get the cover off before I start replacing anything. I know for certain there is a valve cover leak and surprisingly the belt don’t show signs of oil residue at all and looks completely dry and a lot of life on it. I’m sure in the 30 years the seals have been replaced since I doubt it’s the original seals from factory
