Here's a thought. What about drilling out the drain hole as indicated, then pressing in a metal tube from the drain hole exit to below the engine.

Hook up a Shop-Vac to the tube to create positive ventilation under the plenum when you're washing the engine, to avoid drowning your starter.

:dontknow: eh?

great idea! then you could also blow it out if it gets clogged


even keeping the hood down and the engine dry, the LSV was one filthy puppy after 104k miles

gee I never noticed this before but the hole in the back of the block does have a drain hose on my 95


that would also be prone to clogging up based on the gunk accumulated under the plenum

Re: Drill a hole in your engine block???
 

Had the car for about 3 months, first time I took the plenum off, got some coolant on top of the engine, so naturally I hosed it off when I put it all back together. Next week starter wouldn't even click when the engine was hot from a 10 minute drive.

Replaced starter with an ebay NOS and DRILLED THE HOLE as per the service bulletin. Cleaned out the original hole as well and cleaned out any gunk or tiny leaf bits that could plug the holes. Tested the ability to drain water out with just the original hole and with the additional 3/8" hole using a hose. Drains much faster (3-4x faster) with both channels. Wish someone who owned the car over the past 29 years had done it for me.

Get a new 3/8" Titanium drill bit and it will cut through the block like it's made of butter. I created a 45 degree guide out of cardboard cut 6" x 6" to help align the drill. I was off by a little bit, but it still worked great. Took off the plenum and the fuel line between the two fuel rails. Don't need to remove the fuel rails or the injector housings.
