leaky oil bypass valve
#1
My dad's '88 vert had an oil leak at the oil bypass valve. I removed it, tested the valve just for kicks (149*F, 5mm), and it worked fine. The washer didn't look right, so I replaced the washer and bolt from the one from my parts car, which had a washer that fit properly. Started it up, and it still leaked. So bad that you can wipe it off, and watch a drip form within 15 seconds. Should I just try a brand new washer? What else can we try?
Anyone know the torque value of the big bolt?

I just thought of this, could the oil cooler have a crack in it, like from over-tightening the bolt?
it might. try a new washer first

Like j9 said try a new washer. Obviously make sure everything is clean and apply a fine layer of silicone to both sides of the crush washer before you bolt it together.
If it still leaks it's most likely cracked. It can and does happen.

It's cracked. My dad said he put JB weld on it (yuck), if it still leaks he'll get it welded, I also have a spare oil cooler we could try.
welding works and its cheap

Welding works, but you need to have the weldor preheat to remove the embedded oil. Make sure he knows its an OIL cooler. If he charges more than $50 buy another used cooler
yep. usually welding is like $20-$30
