Scotts90 Posted February 13, 2018 Share Posted February 13, 2018 The old girl is feeling poorly. On driving home from uplifting the suspension for the td5 I noticed that the old tdi was beginning to smoke rather more than usual. It was "normal" for it to have some black smoke when hauling from low down the Rev range but this usually cleared as the boost wound up...however we now have predominantly white smoke with some blue in between. It's idling rough too, almost sounding as if on 3cylinders. Theres no pressurisation of the coolant hoses and the temp gauge is sitting bang on its usual spot, no mixing of fluids (yet). It got a head gasket a couple of years ago but this showed with the aforementioned symptoms. (Poor heater, erratic temp gauge, hard hoses) Theres a fair bit of pressure evident on removing the oil filler cap. So, initial thoughts are head and/or gasket issues. Since owning it's always had some blue smoke when cold but cleared when up to temp and it's overdue some TLC. Mulling over a few options; 1) cheap option...whip off head and hope it's the gasket. (Albeit this doesn't solve the startup smoke) 2) disco engines are available...buy/swap over the defender parts then rebuild original 200 at some point 3) buy recon block and head and transfer ancillaries over 4) send original unit for recon Having a spare engine appeals, especially as the pickup is missing one... thoughts and opinions appreciated guys Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted February 13, 2018 Share Posted February 13, 2018 I suppose the main consideration is how long you can have her off the road , and does this mean your going to rebuild the pick up you brought for spares ? Personally I’d go for the disco engine the rebuild her latter , you’ll then have your spare engine and it’ll be cheaper than taking it to someone to do it for you and you should then be able to solve all the problems. cheers Ian Quote Link to comment Share on other sites More sharing options...
Scotts90 Posted February 13, 2018 Author Share Posted February 13, 2018 Being off the road isn't too much of a problem, however I'm an impatient sod. I'd much rather drive the 90 than the D5 or the daughters' Adam. Ice doesn't lend itself to using the Blackbird either... And yes, the pickup isn't being scrapped.

Maverik Posted February 14, 2018 Share Posted February 14, 2018 Just having a head overhaul really helped my ageing 200 to perk up no end. I've got a disco 200 sat in the yard with a tarp over it, with the intention of stripping it down to rebuild to a plane block for when it would be needed, I'd just swap over the ancillaries etc. After having a whole disco 200 previously installed I wouldn't go back to one now I have a defender set-up, the non standard parts thing drove me insane.

Scotts90 Posted February 14, 2018 Author Share Posted February 14, 2018 I've got a 200 tdi disco lump enroute. Just in the process of ordering up some gasket kits to swap over the front case/flywheel housing and inlet/turbo. Quote Link to comment Share on other sites More sharing options...
SanDiego110 Posted February 14, 2018 Share Posted February 14, 2018 I had the same symptoms (crankcase pressure, white smoke) with my 1989 2.5 td, and it was the head gasket. Changed it out and it runs good now, no smoke. Quote Link to comment Share on other sites More sharing options...
Scotts90 Posted February 14, 2018 Author Share Posted February 14, 2018 The symptoms do point toward a head gasket failure, if the head wasn’t showing signs of wear then I’d have just taken the gamble on replacing it. Having a working replacement will allow me to get this one refurbished at my leisure. Also having a set of spare ancillaries is handy.

Maverik Posted February 15, 2018 Share Posted February 15, 2018 Oh and having my head re-built, I used to get some pretty heavy breathing - oil depositing (small pool) into the neck of the filter box, since the refurb, I don't get any of that. If I was you I'd do a top end overhaul for medium term, then get a spare engine built up ready for long term. Quote Link to comment Share on other sites More sharing options...
Scotts90 Posted February 15, 2018 Author Share Posted February 15, 2018 I did consider a re-con head to swap over but I got a whole engine with some new recent parts (turbo/starter/ injection pump) for a fair bit less than a head from turners. I really want to get cracked on with the td5 as the shed being in a mess does my nut in, the engine swap will be an interim fix. Quote Link to comment Share on other sites More sharing options...
Maverik Posted February 19, 2018 Share Posted February 19, 2018 Not cheap, but its given my aged 200 a really nice lease of life, quite horrifyingly actually - just shows how rough it had become. Quote Link to comment Share on other sites More sharing options...

Scotts90 Posted February 19, 2018 Author Share Posted February 19, 2018 Pulled the head off (easy now ) and found an intact gasket but cyl3 pooled with oil, evident wear in the bores too. So, major surgery is underway... Quote Link to comment Share on other sites More sharing options...

Must admit your bores look to be in better shape than mine prior to the re-bore. Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted February 20, 2018 Share Posted February 20, 2018 Any pics of the wear in the bores? I'll be taking the head off mine when I do the chassis swap and it would be good to know what I'm looking for as I've never had it apart to that extent.

western Posted February 20, 2018 Share Posted February 20, 2018 my bores could have been honed & new standard size pistons fitted [3 of the old pistons had a semi circular hairline crack on the thrust side] Have a very close look at your pistons too, so decided to have the block bored 20thou oversize to remove some dark stained areas & new pistons were fitted.

cackshifter Posted February 20, 2018 Share Posted February 20, 2018 I think if you have to replace pistons, unless maybe because something has dropped in, you are better boring, then you are having a clean start. Quote Link to comment Share on other sites More sharing options...
