Suggestions to block off coolant ports (s5 TII)? (turbo coolant feed/heater core)
Hey guys,
My project is getting very close but this is one problem that has been plaguing me for a bit. Engine is a S5 block with S4 internals (for the lower compression rotors).
I need to find a way to blockoff the turbo oil feed (top of rear iron) and the one line for the heater core (under the oil filter pedistal). Heres the catch, I have spent considerable $$$ on this setup, and want something that I can rest assured will hold and not leak causing my engine to overheat.
I would like a solution that is better than "just throwing a hose on and a couple worm clamps sucked tight against a bolt". If anyone has any suggestions please let me know, for the turbo coolat feed I was thinking just using a tap to thread it and then put a bolt in with locktite. But unfortunately the heater core line is much larger and such a setup will not work.
Thanks for the suggestions.

To make sure you guys know the exact ports I am talking about I circled them in red on this picture.
The rad does not have the line because I am using and aftermarket aluminum radiator.
Hmmm that plastic style wine cork is an interesting idea, I would just be concerned about the longevity. Will it be able to hand multiple heat cycles without failing over time. I would like to do this one time and never have to look back.

The turbo oil feed line can be blocked off pretty easily, assuming you're speaking about the outlet on the top of the front iron. You can use a shortened M12x1.50mm bolt, with threads wrapped in teflon tape, with a copper crush warrrsher or o-ring at the base of the bolt head to help seal it up. Hope you already have an idea where you're going to borrow oil for the turbocharger assuming you're still using one.
The way I tackled the larger heater hose outlet on the rear iron was to pull the steel portion out, tap it for 3/4" NPT I think it was, then thread a brass plug in. I also filled in some of the area w/ JB Weld to ensure it wouldn't come out or leak somehow later on.
Hope this helps.

Woops. You mean the turbo coolant feed that normally went to the throttle body's thermowax? You can remove that steel nipple, tap for 1/4"NPT if memory serves, then plug it up w/ a 1/4" NPT plug -- use a metal filler as well to help make sure it doesn't leak. The housing needs to be spotless prior to doing this.

Excellent, so a 3/4" and 1/4" NPT tap, couple NPT plugs, and some JB weld/metal filler. Sounds like a solution I was looking for,just wish I would have done this with the engine still appart. I guess I will just have to run water through the engine to flush out any metal filings to prevent hot spots.
Thanks for the info!
