NLA mercruiser exhaust valve seals
Hi,
I need some (exhaust) valve seals which from GM (OEM) are no longer available…
It’s for a mercruiser (marine) engine 350 cu OD522972
OEM part # 26-852936 which is NLA, is umbrella style seal.
(exhaust) valve dimensions are 1.50X4.923 X .3710
OEM mercruiser # 87284 (valve)
valve stem dimensions are 11/32 op top (so using the same retainers as the inlet valves) then becoming bigger in diameter to 3/8.
Intake valves uses (positive) seal Felpro SS72527 ? But intakes stem are only 11/32.
Base on cylinder head all the same (intake and exhaust)
BB umbrella seals are 3/8 but too wide at the base in the head.
So I’m looking for or umbrella style seal 3/8 top opening but same base dimensions as Felpro SS72527 or positive seal also 3/8 top but same base dimensions as Felpro SS72527
Who can help me out?
