Turbo oil leak


LotusFella

Recommended Posts

My drivers side turbo is leaking oil so am going to get them both rebuilt at turbo dynamics.  My question is, the nuts are seize on and can’t undo them in situ.  Also 1st gear judders a little so my thoughts were to take engine and gearbox out.  I have a 2 post lift but it’s a small garage and would be easier to remove gearbox first then engine.

Any thoughts suggestions on my plan before I go too far? Is it okay to take out in 2?

 Also i have had a search but can’t find any v8 removal threads. If someone would be so kind as to post up a link I’d be grateful.

Thanks.

Just as an observation, that oil seal is not at the correct depth.  There should not be an air gap between the sealing flange of the driveshaft and the dust seal.   If the seals are not leaking then there is an argument not to disturb them, but next time it`s required I would try to ensure that they seal are driven to the correct depth on each respective side.

Thx. I think they do leak. Either them or the driveshaft pins. Another job to do!  Are they difficult?

do you by chance have an image of what they should look like?

thx

There is a tool designed to acheive the correct seal depth for each side.

Mine leak and I did buy the tool and the seals from SJ Sportscars.  I haven't done it yet.  I would ask how long the operation takes, but know it is a while.  Most people say that these seals are notorious for leaking and even new seals will leak somewhat quickly.  What is your opinion on it Mike?

 

Thanks Mark

In the past I never had any issues with the OEM black rubber seals. Of course the seals themselves are only part of the whole solution.  Always use fresh rubber o-rings for the base of the output shafts and a good quality RTV for the split pins. Provided that the contact surfaces were good and the seal installed at the correct depth, the seals always did their job well.  If the driveshaft seal surface is dirty, it really needs to be prepared with some 1200 grit wet and dry to make it perfect.

In recent years, I`ve experienced more issues with the aftermarket brown rubber seals that are supplied these days.  It is sometimes necessary to shorten the seal spring to increase the tension on the lip.  This is easy enough to do and taking approx 10mm off the spring length will increase the pressure. 

For people who have the Quaife ATB diff installed, there is another challenge due to the absense of provision for the the o-ring seal at the base of the output shafts. As described recently in another thread, I used the `double seal` approach to stop leaks on one side.

I addition to what Mike said above about the ATB, my gearbox had O-rings fitted previously but following the ATB figment and no O-ring, I had new single seals fitted, and not had any issues with leaks. It appears to be random as to whether or not leaks occur.

Support the pressure regulator on the inboard flats of the body and undo the front nut.  Once the torque is cracked-off, the nut is free to move independantly from the pipe.

Thx just had to wiggle it out. 
On separate note I’ve removed the top bolt on the hub but the drive shaft doesn’t quite want to come out. Should that be enough or do I have to remove the spring and tie rod

To remove the driveshafts, I`m a fan of dropping the bottom link at the chassis end and leaving the rest in place.  You will have to pull the hub out a wheel/hub out a fair way to dis-engage the driveshaft.

Looks like you`ve got several things on the go.  Were you wanting to remove the plenum to remove the cam covers once again?
