well my 87 turbo II started to lose almost a quart of oil a week and i've noticed that the oil cooler lines are leaking a little. i'll need to replace them soon but i was wondering what is all involved in the replacement. the step by step if you will. any hints and tips are welcome. also which oil lines do you guys recomend? rb, mazdatrix or cork sports? or does it really matter?



thank you in advance

 

you can reuse the 4 banjo bolts, and copper washers. It's pretty easy to get the lines off the block. One is a 17mm, I'm not sure what the other is. But the oil cooler's mounts are rubber so it makes it hard to break the bolts loose on it w/o removing it.



there are 4 10mm nuts holding the oil cooler in place. Just unsrew those and take it out from under the car. It's much easier to work on that way anyways.



Remember what angle and which lines when where when you take it off, because once it's mounted it's hard to tighten them down on the oil cooler it'self.



Block is pretty easy.



Very simple setup. 4 bango bolts 8 copper washers a 17 mm wrench or breaker (impace helps when you have to cooler out) I think the other size is like 22 mm, maybe 24mm. It's a big one. Your gonna make a mess tho.

 

mazdatrix and CS are the same ones. CS just has them cheaper. Definately get SS lines. You will need a 23MM socket and wrench for the job. And lots of towels!



lol



Santiago.

 

so there should be nothing in the way except for the lower plastic cover to get the lines out right? also the ss lines fron cs bolt right up to the block and the oil cooler? if so i'll be ordering mine today

 

A cheaper and more cost effective alternative is to remove your old lines. Take them to a local hydraulic shop and have them rebuilt.

 

i have a lot of stuff taken off of my car right now, so I'm not sure if the a/c condensor will get in the way much, but the oil cooler is only held by 4 10mm nuts. My a/c is gone so I had loads of room to work with.



it's as simple of a setup as a radiator, one line in, one line out. I thought the oil cooler would be more complex too.
