Bridge Port / Coolant Seal Question

[staticpat]

People on here are jumping to conclusions. I'm not mad or trying to trash anyone's work, I just wanted some more insight into the bridgeport. XLR8 actually posted some useful information, thanks for that. I now know that the seal in question will blow out like that over time.

I know the builder and the previous engine owner. It was ran for low miles. but it was in a racecar, so it was ran hard. The builder has offered to take apart the motor and reseat the seal. He didn't have to do that and I appreciate it.

The shop is fine, it wasn't a build problem and I have no problem with the builder. It apparently is the nature of the beast. Now I just need to decide whether to trim the excess seal or pull the motor for overhaul.

No one here is trying to knock the shop (at least not me ) but trust me when I tell you a coolant seal in a new engine poking out like that ***IS NOT THE NATURE OF THE BEAST***

Whether the engine is stock, street, or bridge ported, there's no reason ( otehr then pinching it on assembly) for the coolant seal to dislodge from its oring land. If its properly seated and the engien is assembeled, its physically impossible for the seal to leave the groove unless the groove rots away, or the seal is destroyed by heat or age.

Engine may have ran (and burnt coolant like a mofo) but it is absolutely not normal, or a nature of the beast scenario with a BP.

EDIT: Check this thread http://www.rx7club.com/showthread.ph...hlight=porting

Its got some nice pics of some special bridge ports, you'll notice how the coolant oring land is left intact so the seeals stay in place. If they've ported into that land, thats another reason the seal may have dislodged, and it won't make fora happily running bridgey either.

I used to run a 1/2 bridge engine, and although I faced alot of issues, coolant seals falling in the intake ports was never one of them.
