Hi guys so I have a customer's car in ready for some fab work and something has caught my eye & I believe it's going to cause alot of issues but the customer has been reassured by his engine builder that its fine. But basically they have put a 10mm spacer under 1 engine mount to keep the sump off the steering rack. The mount isn't even sitting flush on the chassis either. Refer to 2nd picture. I will let the pictures do the talking. 

Appreciate any feedback you might have.

In my opinion the motor needs to come out and the sump needs to be notched around the rack. 

You Can see in this pic here where the issue is and it's already been rubbing. 

What issues do you smart gents foresee happening in this situation?

That is pretty ghetto. Considering if you are messing around with a dry sump it is a serious build, not a backyard shit box.

no way would i be ok with that, especially considering it is an AWD car.

Yep it's a serious bit of kit. I wouldn't be happy with it either. 

Think it would eventually crack the sump?  

Diff is obviously gunna be loaded up more on 1 side than the other. Especially when the motor running and twisting under power!

As you can see the engine mount is floating on the chassis already

Ally fretting on steel cross member is either going to wear it paper thin, or cause fatigue.  Problem in the making.

Also I'd reckon the mounts require a zero set - twisting it (power train) while tightening it all down is only going to introduce stress points under load as you say.

Matt's solution looks the goods.

Had same issue - but did something about it.

Thanks mate! That was exactly what I was thinking needed to happen. Unfortunately the owner is going to run with the spacers as he has been reassured there wont be a problem

Wow really?   

I don't think I would like a sump resting on, or chafing on, the subframe like that.   Ironic that you would put a dry sump in for ultimate reliability in oil supply, and then let something like this through.

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
