Rocker cover gasket time, but do I go balls deep?

Post by Mr Footlong » Wed Feb 20, 2019 1:30 pm

Hi guys

Dropped the old girl into my local garage to have a look over the engine and try to figure out why I am smelling what I thought was burning PS fluid. Smell is noticeable especially when the car has been sitting for a week or so, which she does a lot these days. The found no sign of PS fluid leaking and I had checked, the res is sitting on max, but I had noticed that the rocker cover gaskets were looking increasingly leaky, which they have been since I bought her in 2011! I guess that when she has been sitting around for longer periods, more oil has somehow wept on to the manifolds, hence why it is only really noticeable when sitting around for days.

They quoted me 1.5 hours for the NS and 14 hours for the OS, their book must be saying engine pull for the NS as usual I expect.

I have my the chosen specialists (MRC, RD Garage Services in Shepperton and SJB Autotech) putting quotes together for me now, as I am thinking get the engine pulled for the following reasons -

1. The TC has been a fecking trooper, but has been tired since I bought her over 7 years ago now, with the usual hard as hell bang on downshifts sometimes if using kickdown. Jules and I just use the paddles and drop her down a gear or two before we want to baboon it, and she is perfectly happy doing that, we never forget to do that these days. I have a spare TC sitting in a box in my garage, could get that shipped to Yankland and uprated, plop that in one time.

2. Possibly send the gearbox off to say Chester Transmissions etc for a look over/recondition one time?

3. I know that the turbos must have slight weeping on the oil seals, as when she has been sitting around and you fire her up, you can get a little bit of smoke. I really do mean little, but enough to tell and again, they have done bloody well, especially with the extra boost they have been pushing through all these years. Either get them reconditioned or uprated one time? Would be rude not to squeeze some more power out of her if easy enough to achieve, she still hasn't hit 90k yet

4. Look at other general stuff like Bufkin pipe mod etc. and anything else that is far cheaper to do while the lump is out of the car.

I am pretty sure I am right in thinking north of £5k for that lot, but having a wife that says it is the right thing to do, that beast has been so reliable over the years and that she doesn't want me selling the old girl, isn't making it easy for me to say no..... In the daft Bint's own words "I can't help loving the 6's so much!", so it looks like we will continue to own two.

Thoughts, comical or otherwise, appreciated.

CheeRS,

Nick :)

I'd wanna be sure that the banging into gear is definitely the TC and not the gearbox on the way out. It would be a wounder to do all that and get it back together only to realise that it had to come out again. How much are ZF remanufactured boxes going for these days and do they come with the TC? Don't think I'd bother getting it modified. Just all new OE stuff.

I don't think I would go nuts modifying it either. You've got the C7 for autobahn storming and porka shaming. Might as well keep the C5 tiptop and fairly original. It'll thank you for it in the long term. Horses for courses, innit?

Best quote I got for a refurbished 5HP24 in France is 4800 eur excl. VAT, including the TC and oil.

Shopp, but she really isn't very standard as is, that ship sailed a long time ago. The usual intermittent TC error code(s) have flagged on Vagisil since I bought her and the gearbox is as good as gold, except for sometimes banging down into a lower gear a bit when using kickdown, but we haven't used kickdown at motorway speeds in I can't remember how long. The annual/bi-annual gearbox fluid/filter changes make no difference, it just plods along as it has done for the last 30k miles with me.

I figured, have the gearbox looked at and Valve body while it was off the car and I don't know the history of the spare second hand TC I have sitting in the garage, so would want that rebuilt anyway, I don't see the point in keeping OE spec is I can uprate it without sacrificing driveability. MRC specifically reigned the "torgues" in at 832Nm and were certain that she would happily kick out more on a better TC.

I figured I could get a decent transmission specialist to take my existing box in, give it a thorough checkover, possibly renew some bits and perhaps be looking at 2.5k or so for that, I don't really want to swap out the whole box.

Resale/residual value is of absolutely no importance to me whatsoever, mechanical reliability/strength along without sacrificing driveability is what is important to me and both Jules and I are far happier and comfortable in the C5 when "making progress" well in to three digit land on the speedo compared with the C7, I don't think I have even done over 140 in the new one yet, doesn't feel anywhere near as planted as out lovely old turnip. Don't get me wrong, the C7 is fecking awesome, but more in an "oh my God I genuinely think I am going to die if we hit the slightest deviation in the road" when flooring her :D.

Looks like car and wife are keepers!!

Getting stuff redone in US is a faff with customs etc - I think I'd go straight to ZF and get a recon unit from them.

Go for it! :redrs4:

Pricey. Could be cheaper in the UK possibly. Still, could be worth it for peace of mind. How long was the warranty?

/Actually, if a gearbox place is charging 2500 quid to "fix" a box without TC and oil, I think I'd rather pay the extra 1.5k or so to get what is essentially a brand new box except for case. You'll just have to buy one less TV this year, Footers.

See, I can't think of anything happening in the TC that would cause banging when changing down. I'm no expert on all the voodoo going on inside, no doubt, but AFAIK the TC only tries to lock up when you are accelerating at part throttle and the converter speed is already at 90% of the desired coupled speed.

MRC told me my TC was the culprit for my occasional banging. It basically slips under full load for a second, when it should be locking. Then it suddenly locks, which is what the bang is. At least that is what I am led to believe. Mine only does it occasionally and tends to be when flooring it in a higher gear.

As OP, if you use the paddles and drop the gears it tends to be ok. I also never use Kickdown these days just to try and eek a bit more life out of it. After being mapped it's fast enough for the time being without the need for Kickdown.

I’ve sent my spare TC off mate for uprating(not to the USA) and it will handle up to 950nm so there is some where else to send it I don’t want to say to much yet as I’m waiting to get it back but soon as I do I’ll let everyone know who and how much it all cost

Still can't believe we haven't found a place over here that'll do box upgrades. If I wasn't stoopid busy at work and I liked you, I'd strip it a do it for you :wink:
Think every c5 has had weeping rockers.

If the box/engine are pulled there's loads that could be looked at, 5k isn't too bad a price, especially they way you throw it away.

Just to be clear : the price is for a box refurbished directly by ZF Germany, along with the warranty (one year or 100,000km).
I'm sure cheaper prices can be found from other sources. But as you said, 'peace of mind'...

Did my N/S rocker cover gaskets again the other day. Looked like it was weeping at the back down onto the manifold and absolutely stank. I added a touch of silicone this time to locate the gasket a bit better in the rocker cover slots.

Seems to have worked a treat this time. Completely dry around it now and no dodgy smells.
