Kires Posted May 20, 2017 Share Posted May 20, 2017 I'll be using the oil cooler assembly from an 83 turbo. It's being connected to a rebuilt engine that was based on a non-turbo block. Both the cooler hookup and the block have bypass valves. I see no reason for there to be two bypass valves and I'm worried that they'll just make it so that less oil gets cooled and filtered, so I'd like to block one of them off. My question is this. Can I simply pack JB Weld over the block's bypass valve, then sand it smooth once it cures? Or should I pull the valve out and use something like a smaller freeze plug or something? I'm assuming I don't want two bypass valves because in the turbo block, the bypass is filled and covered by a slug. I'm pretty sure covering it with jb weld would be fine, but I'd like to be a more than 'pretty sure' before I start doing permanent-type things to the lubrication system. Thanks!

Use a core plug (aka freeze plug) Quote Link to comment Share on other sites More sharing options...
zxturbo Posted June 2, 2017 Share Posted June 2, 2017 Take it out and use a 3/8 NPT tap. Then use a 3/8 allen head plug. Very easy took me all of 5min. Quote Link to comment Share on other sites More sharing options...
fraz Posted June 2, 2017 Share Posted June 2, 2017 What's the easiest way to get it out? I struggled a bit to get the tube out that holds the spring and ball. Got it out in the end and also tapped to 3/8 npt Quote Link to comment Share on other sites More sharing options...
zxturbo Posted June 20, 2017 Share Posted June 20, 2017 Sorry I have been away. My mom has been in the hospital with congestive heart failure. I'm glad u got it out. The 3/8 NPT tap is the easiest and fastest way. Quote Link to comment Share on other sites More sharing options...
