Oil Leak

[jims-terrano]

Discovered an oil leak on the project truck, at first looked like it was oil filter but doesn't look like it now. Had my hand down there and looks and feels like some kind of like a metal pipe and bango bolt. It's just above oil filter and slightly towards the front. This banjo bolt is defo thick with liquid black oil so pretty sure that's the culprit. Banjo bolt feels as if it screws into the oil filter housing but can't be sure.
I've decided not to use it until I've sorted this out. My son is going to try and take a look this afternoon and possibly photos too.

Any advice would be appreciated. If anyone has any photos of a Terrano engine it would be appreciated too.

Thanks

I'm sure a tweek on the bolt would sort it or remove bolt nd renew copper washer as sometimes they can split

OK guys have a look at this, do you think it is this banjo bolt that needs nipping up or the oil filter that's weeping?

As said above I would change the copper washers.

I would try ti tighten up the filter if you can as it's known for the odd one to work a little loose then blast the whole area with a pressure washer & some detergent let it fully dry then cover that area in talc & start the engine up & the talc will pin point where the leak is coming from as it'll turn black, putting a bit of cardboard between the filter housing & cooling fan will help stop the fan from blowing the talc away. It was reported on here quite a few years ago some filter housing were developing cracks in them where the bango bolt go's in hoping this isn't your case but know Cosmic suffered this on his

before you touch it I would liberally spray the area with degreaser then hose it off pressure washer if you have it, that pipe if my memory serves me correctly is the oil feed to the turbo and as such can be prone to cracking, simply because the turbo is on the exhaust manifold and the pipe joins it to the filter housing repeated heating and cooling cycles can cause this sort of connecting pipe to fracture, usually occurs near the banjo due to heat stress when it was brassed at manufacture, Rick

Cheers Rick, will get some degreaser and give it a clean off at the weekend. Now I know it is a turbo feed I think it may be better to leave the car alone until it's fixed.

Wonder if it could of been knocked when the front pipe was replaced?

it might just be that the banjo bolt needs a nip as that is where the oil looks like it is coming from, but it could be running down the back of the pipe, so clean first then check, but it is not a serious leak only a weep so no reason not to use the motor on short runs, but not for plowing up the motorway, Rick

 

[jims-terrano]

Think I might nip it up at the same time as cleaning.

What a shame I've got a lot going on every weekend up to December, probably got Sunday off so fingers crossed weather isn't too bad.

 

[jims-terrano]

Well been and given it a good dose of looking at with Mattsterrano and discovered the oil filter was loose or at least not as tight as I would of expected. So cleaned the area off with rags and started the engine whilst we changed the wheel on the other terrano. Then went back for a look but not good. Oil is seeping out from around the banjo bolt. We are hoping it's just the washers that need replacing as we can't see oil around the metal pipe.

So does anyone know what size the copper washers are?

 

[solarman216]

did you test it for tightness? Rick

 

[jims-terrano]

Forgot to say sorry. Mattsterrano checked it and it's tight.

 

[solarman216]

I would try backing it off and re tightening, failing that I will have a look on my scrapper to see if they are still there, you could also try removing them and annealing them also give you a chance to see if there are any marks of debris that might have got on them when last assembled, I very rarely find the need to renew copper washers, Rick

 

[jims-terrano]

An interesting point Rick, will try slackening and tightening them tomorrow evening. Know annealing was discussed a month or so back but isn't it heating up until it's glowing and quenching in water? Or just heating and letting it cool on it's own. I'm sure my dad's old blow lamp will provide the heat.

yes heat till glowing then drop in water, it will soften still if you just let it cool but scale can remain which you do not want, Rick

 

[jims-terrano]

Cheers Rick, will see what tomorrow evening brings.

OK guys took a good look at this today. I removed the bolt and although I wasn't 100% sure there was anything wrong with the existing washers they did have some marks that could of been cracks and what looked like pitting so off to local motor shop. Got 4 thinner copper washers and fitted those in place doubling up so that it built up the thickness. Started her up and made a cuppa, after a few minuts I wasn't too sure whether that was a drop oil or residue. Had a good feel and yeah defo still weaping. So gave the banjo bolt a nip up and started her up and sat down with my cuppa. Oh dear the weap had turned into a good strong dripping.

So is it because there are 4 washers instead of 2 and they haven't sealed or is it the pipe. I'm assuming it's the pipe but can't really see where it goes. I'm going to let it cool down and remove 2 pf the washers and see if that makes any difference.

Thoughts please?

 

[jims-terrano]

Fingers crossed I might have it sorted but going to keep an eye on it. Removed two of the washers so just using two of the new thinner washers and seems ok. Put it up on ramps and brushed gunk all over underneath and then hosed it off.

Hiya Jim, I've just had a look on mine, is it the pipe that comes up round back of intercooler hose and then back down to turbo?

 

[jims-terrano]

Yeah had a look and yeah think that's it. There are two metal oil pipes I can see going to the turbo and it's the one at the back nearest the head. Hopefully I've got it sorted as I don't really fancy replacing the pipe.

Before I had worked on the project truck I really wouldn't of even tried to fix it so I'm well pleased.
