84 300D Turbo Oil Leak and MacGyver Repair

Howdy All -

First the Turbo Oil Return Leak, please confirm the return is a somewhat oval shaped fitting held to the bottom of the turbo with 2 bolts and then is a "squigly" looking pipe into a straight pipe to the pan.

What has been your experiences with pulling those bolts are they breaking off ? I would hate to kill the turbo for a small oil leak.

Ok now for the MacGyver, for the fix it right guys I am sorry, while I was under the car I reached up to grab a light and a rag and accidentaly grabed the small overflow (? ) line that runs from the top of the radiator to the plastic coolant resivour and it came off right at the radiator, to mee they way this piece was molded it looked as if I would have to replace the entire radiator for this tiny piece so I took a sheet metal screw and RTV Orange and screwed it in, I am going to let the car sit for a day before I get it warm and build some pressure in the cooling system, Any thoughts ?
How much pressure is in this cooling system ?

Please don't say buy a new radiator, I could have said that myself

Thanks

Tr0y

my oil return came off w/ no probs

while your mcgyver plug may hold, it does not let air out of the system so it may pool in the pressure reservoir. Pressure that usually passes my the cap may burst hoses. Perhaps before you buy a new radiatior you could thread the old hole and send in a small nipple?? May work, not an incredible amount of pressure on coolant systems, especially on small surface areas.. check your cap for the release pressure

Pressure is 14-22psi depending on what bottle cap you have (100, 110, 120, 140mbar).

Parallel universe type situation. That line from the radiator to the overflow is in the worst possible place. Anytime I'm working on that side of the car I find myself leaning into it. Well, a couple of weeks ago, I leaned into it for the last time--snapped that damned nipple right off. I researched the mcgyver fixes and concluded that a new radiator was less of a risk and would take less time to install than to do the fitting, tapping, etc. And time is more important to me right now. Last Thursday, my indy let me get my car on his rack so I could replace my oil pan gasket. I know, he's a real cool dude. While I was under there I looked up and saw a little leak at the upper turbo drain pipe where it fits into the turbo. So I borrowed a super wild extension and swivel socket and got nasty on that bolt. Well, broke the thing right in two. Did I mention my indy is pretty cool? He let me leave the car on the lift almost all day friday for me to remove the turbo and get that broken bolt out.

My advice would be to get a new radiator (279 for a Behr better than original from Autohasz) and take it easy on those bolts on the turbo. I wouldn't try to fix a little leak there just by tightening. I'd do it the right way--the way I should have done it in the first place--and removed the entire tube and replaced the gaskets and lower grommet all at once. Btw, that lower tube is a pain to get out.

Good luck!
