Im not sure if I can use this but I have a small oil leak from the oil cooler lines im not too worried about it right now, but whenever it decides to gets worse im thinking about either RTV, or maby replacing the O rings? The lines arnt too expensive but im not in any position to be doing big time work on my car since were moving to California next month. Anyone ever tried RTV on these?

 

Would be a temporary fix, wouldnt trust it for too long.


Where exactly along the line are we talking? Quick release? At the block?

Where exactly are they leaking? The banjo bolts use copper crush washers and there are O rings used for the quick disconnects. All these part are available from Mazda.

its .... kinda hard to describe, but its NOT next to the oil cooler itself thank God.. its like... I see the oil leaking from where one oil pipe connects to another one. It looks like a BIG job once again, but dooable. I traced the leaky line and Im sure its an oil line for the cooler. If I dry it up very well ... and I mean VERY well, then use RTV... would it work well?

 

That doesn't sound like too big of a job to me. Like was mentioned before, get the o-rings for the oil line quick disconnect from Mazda. Next time you do an oil change, separate the lines (usually quite easy to do), replace the o-rings and re-connect the lines. Putting RTV around the lines probably won't do anything at all.

 

oh, so I dont have to actually remove the lines to fix the problem, I can just loosen the lines then replace the O- rings?

 

dude if these are your original lines you should just replace them. shortcuts like this result in blown motors.

 

RTV silicone sealant is NOT the solution here my friend. Grab the shop manual and review the oil line circuits. See the O-rings and the C-clips. Realize the potential for a complete engine meltdown. And do it right - fix the problem - never patch, or attempt to patch.

Here, I'll help you....93 shop manual pages D-2, D-8 and D-9. The O-ring is back in a groove in the Female side.

ok its been already a year since ive had this problem and now im finally ready to fix this. Ive realized that the leak appears to be coming from the "quick disconnect" on one of the lines.

I found where the O-rings are located, and ive decided to replace all the oil cooler line O-rings on both lines, along with all bolts and clips. The lines themselves are in good shape, im basically just going to rebuild it, and it should save a lot of money, and the problem will still be solved the right way. Thanks for the help, im glad I didnt decide to use RTV

 

Goodeye Ernesto !!

You can purchase the entire end of the line. Its about $30 from Mazda. Comes with the 0-ring. I am not sure if you can buy the o-ring my itself. Make sure you order the large copper crush washer that goes 0ebtween the line and the end. They are different than the ones that take the banjo from the front cover and oil filter pedestal.

 

Does anybody know what size wrenches to use to remove the Oil cooler line quick disconnnect?

 

22 or 23 mm

Ok so far I have managed to get one connector in, but something weird is going on here. The new connector is on, but for some reason if I twist it with my hand, I can twist the connnector, it kinda feels loose?

The clip is in for sure because if I pull as hard as I can I cannot remove the connector line, but if I twist it, it moves a lot... Is this normal or whats goin on??

 

That is normal for that type of clip.

 

C'mon Ernesto ! You know you are relying on O-rings to seal that connection - not a theaded joint.

Oh... thanks lol well I originally planned on replacing 2 oil cooler lines connectors, but the other one was not leaking, PLUS its all rusted out and when I took the clip off of that one it still doesnt move at all lol I dont think that one will leak since it seems to have welded itself together throughout the years. OK well thats done!
