If certain intake gaskets are used, then it's possible to get a coolant leak into the heads.
The rear main seal is also a trouble spot as there are two seal halves, along with side seals, since the block is a skirted design. Different windage trays and oil pans can also play havoc here as they block the return in the rear main cap.
All of these things need to be watched carefully upon assembly. Otherwise it's smooth sailing. |
FE's are tricky to seal properly.
My 428 was built and the BOZO used red silicone on the intake gaskets.
The gasket slid and coolant was in the motor
oil.
Rear mains seals are difficult to get to stop leaking on these engines too.
