Oil Leak - Intake Side of Engine.

[MARKx4]

Thankyou for the pics, where do they plumb into and do you have a return line to the sump?

From memory the pipes from the injector pump to the injector have to come off.
It's more time consuming than challenging.

have just fitted oil catch to my 4jb1t had oil both before and after turbo and some traces of of blue smoke, only had the catch on 3 days now and already noticing a marked improvement inlet to turbo now much dryer and blue smoke seems to have cleared up now

next step is to plumb catch drain into dip stick with a one way valve so collected oil gets reused

sounds like the catch will help things

i need a catch can still too... mine still uses a little oil, has got better after changing the air filter
wat size fittings are you guys running on yours?
and im guessing it easier to buy one with the in, out, drain and atmo fittings in it already

Generally we dont run the breather to atmosphere. In normal applications it is better to but if used off road its another place water can get in. We plumb it onto the intake at the same point it was fitted to before the catch can was fitted

Here is some pics of DIY oil catch i have just installed

basically made from a drinking flask, domestic plumbing fittings and stainless steel wool

the catch was fairly simple but the one way valve took a little more time to refine

thanks to pig75 for the idea to use a ball bearing i was able to achieve this

The bearing needs to be about 1 to 2 mm smaller than the fitting you are placing it in if its to big the oil wont drain past if its to small it wont close i used a washer to make a seat for bearing to stop at
first tried the none return valve in a vertical position but pressure from sump was not enough to cause valve to close
using valve in horizontal position worked perfectly

Managed to do hole thing for $20 as had most fittings already lying around

the T connection into dip stick is only temp at the moment am having one welded on next week

hope this is helpful to anyone looking to build there own and thanks again to pig75 for the inspiration with none return valve

regards

post edit 02.08.2010 this catch design was to small and the inlet pipe was to close to the bottom of catch can

If you can find a broken 3.1 engine the dipstick tube is the same but already has a connection for the pipe

[steveNZ]

Good thinking i know a guy with one in a field still got block and dip stick intact will give him a call
if not have a spare pipe from blown 2.8 so will get T welded or braised on in future using a modified compression fitting from 12 mm aircon at the moment, was a bit of play in it so it took a bit of packing should be good for the short term

thanks for the info alan
