"Interesting" water leak....
Posted: Mon Apr 06, 2020 1:22 pm
I noticed some water under my Plus 2s the other day. It was dripping off the bottom of the bell housing where it meets the engine. Initially i thought the heater hose that runs across the back of the engine to the thermostat housing (and in fact after removing it it was damaged - a tiny pin prick hole where the pipe was chaffing on the back of the block), but having replaced it, the leak was still present.
To investigate further, I removed the cover plate on the front of the the bell housing. It turns out that the water is dripping from the bottom of the "lip" of the sum where it forms the crank seal. Most of it is dripping straight down and then coming out of the bell housing between it and the cover, but some has obviously been running down the flywheel itself - i have a nice rusty streak across it. This makes me think the water must be coming from above it (and pretty much line with the center of the flywheel).
So the question is, where is the water coming from? I'm "hoping" it's just the rear core plug leaking (but why??) rather than a crack in the block. But before i whip the engine out, any other theories? Also, since the manual implies i can separate the engine from the gear box which the box in-situe (in order to take the engine out on its own), anyone care to comment on the chances of changing that core plug without taking the engine all the way out?
Thanks in advance
