Pe-90 w/ 0470 cylinders Gaskets 8-bolt?

1)Best place to find gaskets? Anything i should know? Reason is one is wet all around and dripping. Very slowly but dripping. That same cylinder is the one that occasionally has a "Tik tik tik"....

2)Also, I need the donut seal for the pickup that goes down into the oil pan in front, its seeping out.

3)The pressure tubes coming out of front and top-rear of engine... sometimes i lose some oil through that. Is there a way to eliminate those? or somehow get rid of tube coming up and over the cage?

remember that any condensation runs right back down those tubes and into your engine!

For the rocker cover gaskets, Call aircraft spruce, part #534857.

As stated above, Ducarra aviation will have the o ring for the pickup flange, if you can sneak the flange up off the pan gasket, a bit of brake cleaner to remove oil residue, a thin film of permatex "right stuff" around the sleeve, slide flange back down, bolt it back.


Omit and plate off the rear breather, take front breather, get a hose that is larger diameter, there should be a baffle behind the top accessory plate to keep oil from splashing into the hose.

That was a fun little boat, likely built it 28 or so years ago.
