Hey Gene, How do you install timing cover with motor in boat

[Hardtop Trophy]

Ok, Gene, I am at my wits end!

I have 1995 Trophy, 2359, with 5.7 litre, Thunderbolt IV. Alpha 1 Gen II.

I think I found my oil leak (crankshaft seal ). I didn't think anything of it and I pulled the timing cover. I am now ready to re-install the timing cover with the oil pan intact and motor still in the boat. I can not find a way to push hard enough to compress the rubber gasket that rides on the oil pan/to timing cover and pop it in.

Do you just run a LARGE BEAD of silicone, let it firm up and then install the cover without the rubber gasket?

I am ready to do that now! Please help!! :cry:

Here's the procedure....I assume you have a tin front cover... On the inside of the lower cover is a "channel" the seal rides in. You take a set of snips and cut the upper corners of the inside lip at an angle, about 90* or so. So if you are looking at the inside of the cover, the top of the channel is cut straight horizontal. You will trim it so the inside lip will be a straight vertical cut instead. I'm guessing you will remove about a 1/4 " by 1/2" triangle of metal from each upper corner. I usually take a smidge off the seal ends also. That would be the really small tapered edge that seals between the block and pan. This will allow the cover to slide back in the block. Take some yellow death, gorrilla snot or 3M quick dry trim adhesive and glue the seal into the groove. Let it set a while. Loosen the front 2 bolts on each side of the oil pan a little. Clean everything again, brake clean or acetone. Put a thin bead of RTV on the outside surface of the seal and in the gap between the oil pan and block. Set the timing cover in place on bottom and use two smallish phillips screwdivers about 1/2 way up on the cover. Place the drivers through the bolt holes in the cover and into the matching hole in the block. You then apply downward pressure on the drivers while applying pressure against the cover with your thumbs. The cover should just slide in. Much easier to do than describe though.... PLEASE call if you need any verbal guidance . Number is in the addy forum.
