Hey guys, just put my 88 tc back together, and I'm getting a leak just under the oil pressure sending unit. I believe it's from the oil feed line that runs over to the turbo. We had the whole intake off to look at the line, we took it off, but couldn't find any problems. Has anyone had this happen before? I'll probably just buy a new line from Forced4.com, but I just don't understand what would cause this. I didn't see any pinholes, and the fitting seemed ok.
Just let me know.
The lines can crack in that vicinity. It's happened to several people. I'd recommend a new line anyhow if the old one got dried out. Varnish may flake off and plug the turbo oil passages.
This is not an uncommon problem. It's one of the more common places to develop a leak. Don't bother with getting a stock style replacement though. Get a braided stainless line like the one towards the bottom of the page in the following link. It's easier to install in my opinion and you'll have less problems with it in the long run.

Sir you can buy a length of brake tubing at an auto parts store and make a new one. They come in several pre made straight lengths and can be bent into a new line. The stock line is stainless and i make my own from stainless line. But you will need a hydrulic flaring tool. The pre made lengths can be installed. And if you have a flaring tool you can cut to length and reflair. But the pre made lengths can be used and bent to fit. The line is available at any auto store and is cheap. Hope this helps Sir
