    Posted: 09 Nov 16 at 15:56
Hi all,
 
Not an upgrade as such (yet). But my oil filter and oil cooler (standard oil cooler) keeps coming loose!
 
Looking around this could be due to an oil pressure issue? I assembled the cooler and new filter to correct torque according to Haynes manual so I am surprised it's come loose again.
 
Has anybody got any advice on this issue? Shall I fit a pressure gauge so I can monitor whether its pressure that is causing this?
 
Many thanks,
 
Adrian

It's a massive nut yes? 32mm I guess it's the oil lubricating the nut.

What torque you using?

Maybe take of the housing and degrease it really throughly and then reassemble?
Mine have never come loose and I just did them up tight ish on a ½" socket?

Thanks for your reply, I checked the cooler/filter had come loose and it hadn't after all. Hence the oil isn't leaking from there.
 
It's all around the sump gasket joint which leads me to think it may need a sump gasket. My quest to find the ideal gasket on the internet hasn't really provided anything conclusive.
 
There seem to be 2 gasket options:
 
- A rubber gasket
- A rubber gasket with a baffle. To complicate things further it sounds like this type would need different/longer sump bolts - although nowhere seems to reveal exactly what type/length of bolt is needed, or give the VW part number, at this stage I have no idea what length bolts are/have been used on the van currently. Also it suggests this type needs the oil pump to be removed, and is recommended to be replaced at the same time?
 
Obviously the oil may be leaking from elsewhere - I've not found a suitable day to really check conclusively.
 
The dipstick tube is loose in the block - its just rattly in there. I popped a copper washer and rubber O-ring from brickwerks in in an attempt to solve that but it has made no difference and basically just got the copper washer stuck. Ideally I'd like to machine a knurled brass or aluminium sleeve to press in but haven't got the time just now. I'm considering chemical metal for the time being? (Or is that a really really bad idea....?) The tube doesn't seem like a legitimate dipstick tube anyway, I wish I could find a supplier of a plug and play tube that would just fit correctly!
 
The van is chucking oil out pretty bad so I've barely used it for weeks now. I don't really have capacity to be able to throw a lot of time at it so just need to solve this as best as I can with a few hours chucked at it here and there.
 
Please help :)
 
Thanks very much,
 
Adrian

Just use the rubber gasket. You don't need the windage tray one.

Dip stick will need a metal sleeve making up to actually fit the whole. The JX one is too small.
I always drilled out the original AAZ dipstick tube as sleeve and then wedged the JX one through that.
They don't actually fit so the rubber washer is useless.
Not sure why this is never mentioned but it is defo the case.

So I've not really made any progress solving this oil leak....
I've been using the van rarely and leaving a small puddle where ever I park up.
 
I think the rocker cover is leaking a bit as well.
 
I could have an overfilled engine, the lack of a useable dipstick is making this difficult.
 
My plan is to change:
 
- sump gasket
- rocker cover gasket
- oil cooler flange to block gasket
 
Does anyone have any suggestions of any others to change while I am there?
 
Also, completely noob question (I've never owned a diesel before). What is the part that is assembled in the same place as a distributor on a GTI 8v?
 
I've tried hunting the net for an answer and I'm not finding one anywhere.....
 
Cheers,
 
Adrian

Thats the vacuum pump, makes sure the servo assist has vacuum in it.  It's driven from the idler shaft and has a keyway in the base to also drive the oil pump
