JK oil leak

[Jeep'ers]

Yep if it’s coming down round the bell housing it looks like it’s the oil cooler adaptor...

In the past year I’ve done this job three times, twice with different mechanics the first over torqued the part cracking it, the second using a silicone on the o rings and it also failed at the sensors, third time I’ve done it myself and has stopped the leak completely, however I didn’t tighten to 12nm only 9 so I’m going back in today to tighten to the right spec...

Not a hard job to do, just messy... took me about an hour or two to complete.

All three coolers were aftermarket but I suspect the first two were duds.

The mopar part isn’t that much more expensive , give Sutton’s parts distributor in lidcombe a call or Peter warren parts in Warrick farm a call... they should have one..

Common problem on the pentastar

Also if you’re going to do this job yourself, get the lower intake seals as well both upper and lower, also doing the spark plugs at the same time as you’ll have access to all of them

Are you thinking of a DIY?

Yeah I’ll do it myself.

Just spoke to Sutton’s, god that part is expensive 550.

I bought a cheap eBay one second time round and it lasted a month... in saying that they refunded the money
