Turbo Oil And Cooling Lines

[Trevsked]

Doesn't sound very promising for my cars future. Once I get my wheels back I guess this will be first on the list.

I think these parts have to be treated under preventative maintenance. If they look iffy then change them.

Pity really as I was planning to pull the engine later this year to do the belts, tensioners and those manifold heat shields. I was just hoping they would have lasted til then.

Oops..... that will be a nice little bill then

'little bill' ????

Mechanic has warned me already to expect the full 'WILLIAM'

Guys, Need a bit of advise here - basically i am faced with having to replace ALL the water & oil feeds to the turbos on my V8, but what i really need to know IS - is this do-able with the engine still in the car!???

My cousin has already taken two of the hoses off (the one that runs up to the "T" piece!), but as for the others he's telling me that he can't even see them or feel them so it's NOT looking good, But if at all possible i would like to try and DIY swap all the hoses myself without having to revert to the possibility of taking the engine out, but from what i have been told it looks next to impossible to do!

Keep in-mind that we DON'T have access to a pit or ramp/ramps and that this will have to be done with the back end of the car up on axle stands if we/ I give it a shot, as the car is now effectively immobilsed! If it's a definite no-go then the car will simply have to be trailered to a specialist and go from there, but i'd like to think there's atleast a chance we can save ourselves several hundred pounds in Labour charges if we can do the swap between us!!!!!!!

Am i dreaming, or is it do-able with the right tools and a dose of luck and patience!???

Im REALLY hoping so as i've spent over £2k already getting/doing various bits this year already!!!!

[mike_sekinger]

Yes - the turbo hoses can be replaced with the engine in-situ.

It is a case of the right procedure, tools and, as you say, patience.

The hoses themselves are going to cost you upwards of 500GBP if you go OE.

Hi Mike,

Thanks for the reply, and i have to start out by saying that that's a relief! I know my cousin is convinced that it's a definite "engine out" job, but if you say it CAN be be done engine in situ then it could well save me £££'s!

Could you (or anyone else for that matter!) give me any pointers on how to proceed though!? Is there anything that will have to come off to allow access to any of the pipes (engine mounts, or does it mean dropping the turbo's themselves off!?)

If i can get a general idea of what i need to do that'd be great so i know where to start and what to do/ what not to etc!

As for the cost of the pipes - then tell me about it!, I've already bought n payed for them - got em from SJ!

We did look at getting hoses fabbed up, but the place my cousin went to to try weren't able to get anywhere near tbh, o.d of hoses was a lot bigger etc, so we plumped for buying all new o.e stuff as i wanted to make sure we'd have no issues with routing of pipes etc! We would have tried harder to source some aftermarket jobbies, but i want to get the esprit up and running again soon as poss so i can swap it for my CTR and my cousin can hopefully then do some work on that for me!

[Trevsked]

Blue Harbour,

As you got all the hoses from SJ what did the total come to? I had a look on his site and it looks like £100 a hose x 8 so £800 plus a few gaskets and washer so would think it is around £1000.00?

Had you bought them from me or Strattons you'd have got 10% off as a full forum member!

[Trevsked]

Bibs,

Get a price if you would for these and post it up. There are loads of V8's out there with the same issue and we need a "kit price". I am sure we would all want to buy from other people than SJ but as he is one of the few with web prices advertised it makes it the simplest route and that road is the easiest travelled.

Trevor.

A list of parts is perhaps a start. If anyone has additions to this please feel free. In an earlier post I assumed there were 8 pipes but it seems there are only 6.

A918E6087F x8 Banjo washers

A918E0189F Coolant Pipe retrun RH

A918E0194F Turbo oil feed RH

A918E0188F Coolant pipe feed RH

A918E0030F Gasket elbow to turbo x2

A918E0190F Pipe turbo coolant feed LH

A918E0191F Pipe tuirbo coolant return LH

A918E0187F Pipe turbo oil feed LH

A918E0181F Hose sump to turbo long

A918E0023F Plenum gaskets x2. I don't know if it is reuired to remove the plenum but I would be doing this to change mu Idle Air Control Valve and it may make access to the engine a little easier.

Trevor.

[Bibs]

Thanks Trev, leave it with me!

[mike_sekinger]

A list of parts is perhaps a start. If anyone has additions to this please feel free. In an earlier post I assumed there were 8 pipes but it seems there are only 6.

Yes - only 6 pipes. The oil returns are cast pipes from the turbos direct to the sump (via silicone coulings).

Cheers,

Bibs,

Great work and thanks for getting the prices. Will be in touch.

I made my own SS lines for about 300-400US!!

12mm to -4AN adapter for the oil feed lines.

-4AN feed lines 13" long with straight on one end and 90 degree on the other

-6AN coolant feed line with straight on one end and 90 degree on the other, I put in block adapters for the coolant feed lines that were straight block thread to -6AN (can't remember the block thread and size off the top of my head.

-6AN coolant return lines with proper turbo to -6AN adapters.

I can dig up the block adapter info but on the turbo side I was mating to a GT28 BB CHAR to my turbo connections

[blue harbour]

As part of attempting to do this job tomorrow (oil and collant pipe renewal) I have been advised that we'll need to drop the aircon pump out of the way to get access to one of the unions/pipes - is this accurate, and if so how do we relieve the tension on the serpentine drive belt!? Is it done by going off the bolt on the tensioner itself and cranking it counter clockwise or i see there is a square slot further up on the arm- do you use this, and what size is this whole (1/2"???)

We will be doing this without the aid of a ramp btw (don't know whether that will have any bearing!?)

[mike_sekinger]

HI Matt,

Use the square 1/2" drive on the arm to relieve the aux. belt tensioner - moving anti-clockwise.

If you are also replacing the coolant feed adaptor fittings into the block, then the use of some Loctite 572 thread sealant is a good idea.

While you have the AC out of the way, you could also check the LH exhaust manifold heat shield for cracks. These cause the awful tinny vibration and that would be a chance to replace, since it is practically impossible when everything is together.

Good luck.

[blue harbour]

Hi Mike- Cheers for the reply!

I do know that there is a heatshield that's going/rattling, but because of how much i've already spent i never ordered any as it's not that bad atm, Question is though if whilst were doing the pipes we do find the culprit and we do decide to try and remove it is it a must that it's replaced!?, or do some folks run without them!?

I did see some uprated jobbies on Ramspott, but like i say i didn't commit due to the money i've already committed so far!

Cheers Matt!

[mike_sekinger]

Hi Matt,

I wouldn´t recommend running without the heat shields unless you were using coated manifolds.

I do have a bunch of spare ones if you do find that yours are cracked. Just drop me your address and I´ll stick some in the post if you want.

Keep us posted.

Cheers,

Mike S

[blue harbour]

Well were "nearly" there!

We've got all but one of the pipes fitted (you can probably guess which one has been left till last!)

What i could do with knowing is whether (when we attempt to/look at dropping the AC compressor) will we need to drain it, or can you leave it connected!?? I ask because the pipes that come off it are metal jobbies and not flexi's so i can see it being a huge PITA, and from weve been told even after dropping the compressor there'll still be little room to work!

This is NOT a job i'd ever want to do again- everything has been a massive PITA, from stupidly innacessible bolts/unions to having to cut spanners or shave down 1/4" drive adaptors to get us clearance to put ratchets on sockets! Really horrible job, and imho anyone who tackles and conquers this job (especially in the way we've had to do it!) deserves a flippin medal like a bin lid and a looooong well earned rest!

Just hope we CAN do this last (worst) hose as this will have saved us £££'s in labour costs!

[Sparky]

Finally catching up with a bit of Lotus work, I went round Trev's this afternoon to have a crack at his S350 lines which were pretty rough. We managed 5 of the 6 in 5 hours, and only had to mod one spanner. We're saving the best(!) one till last, and, with considerable luck and an inexhaustible supply of expletives, will hopefully see it back on the road tomorrow.

[redshift]

, and only had to mod one spanner.

Let me guess... LH oil feed on the top of the turbo??

Absolutely b******r all clearance to work with. God knows what tools they have in the factory to do this.

[Sparky]

Smartass!

[Trevsked]

Didn't do any work on the car over the Bank Holiday weekend but got a couple of hours on it tonight. Replaced the left hand turbo coolant pipe that runs forward to the block. This is by far the most awkward of all the turbo hoses and caused a lot of head scratching and searching through different sockets and ratchets to get the right combo to get the job done. Not easy but can be done with patience. I looked at a couple of pics of the engine and diagrams in the workshop manual over the weekend and thought It would be simply removing the A/C compressor but once back under the car this is not an option. My method was to remove the turbo inlet hose, oil filter and engine mount. With these out of the way access to the block fitting is just possible.

Have just had my turbos replaced and had the hoses done at the same time. Engine in situ. turbos from R&B. The hoses I got from Pete at PNM at the Lotus Donington event and paid a very VERY reasonable price.

Here's the finished article...

and the kit...

Edited December 11, 2011 by CharlieC

[peter_england99]

Hi CharlieC, How much did you pay for the hoses for both turbos?

Regards,

Peter.

[V8 FOU]

Just ordered a kit from PNM today - 3 different kits available, most comprehensive one is about £360. Made sense to do this while the engine is out for belts, mounts, tanks etc etc
