Team Idris Posted August 23, 2012 Share Posted August 23, 2012 We did the head gasket + new head and still have oil in the water. But only on motorway work. My guess is the oil cooler on the side of the block? Disscuss Pretty fliperty annoying I can tell you. Black oil maybe should have been a give away, and typical of a heat exchanger that only leaks when thermally expanded. Quote Link to comment Share on other sites More sharing options...
sierrafery Posted August 24, 2012 Share Posted August 24, 2012 it seems a good theory... unfortunately they used to fail, expensive stuff, usually they leak out too... there is repair kit now but it's not cheap either http://www.paddockspares.com/td5-oil-cooler-repair-kit.html Quote Link to comment Share on other sites More sharing options...
Team Idris Posted August 24, 2012 Author Share Posted August 24, 2012 I didn't think that was too bad a price considering the production numbers and what a pig they are to make. And way cheaper than the £900 head Should be a good truck when it is done, but still need a look in the clutch. Somebody with a lift and a support frame can tackle that though. Rangy racer is bad enough, and the floor comes out of that Quote Link to comment Share on other sites More sharing options...
RedLineMike Posted August 24, 2012 Share Posted August 24, 2012 looking at that, its given me an idea on how to fit an external oil cooler to my td5 Quote Link to comment Share on other sites More sharing options...
Team Idris Posted August 24, 2012 Author Share Posted August 24, 2012 Woohay, long timey no speaky. I thought about you, being a Td5 man Same here with the external dry cooler idea. Shelves of Serc coolers at work, but how easy to exit the block's oil galleries? So I wrote to Andy Allisport to see if he had any fixes or advice. Nothing back yet, and maybe being a road motor it's best to stick with normal-ish parts. Really it hinged on how the outside of the ally housing looked? Is it plain or is it covered by the spinner and oil filter? Would it need a sandwich block? I'm keen to see what the banjo bolts do, so hopefully Terry will ring us when its in bits Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted August 24, 2012 Share Posted August 24, 2012 We thought of maybe bypassing the thingy somehow. (But never got around to it) Often the leaking ones have a pinhole leak and can be welded. Quote Link to comment Share on other sites More sharing options...
Team Idris Posted August 26, 2012 Author Share Posted August 26, 2012 AHA! Cooler corroded around O ring so the internal O rings popped. The housing has not corroded at the same point, but it has where it goes to the block. So we think best to get a 'complete' package. The housing works out about £140, so not worth welding and milling flat, given the trouble it could cause loosing coolant. Not to mention risk of swalf in the galleries from milling! I have the old housing here all cleaned up. I hope to make a CAD drawing of the hole pattern so anyone on here can get a 19mm ally plate water jetted out. Then you can fit a remote filter housing and the spinner if you feel the need? Quote Link to comment Share on other sites More sharing options...
Team Idris Posted September 16, 2012 Author Share Posted September 16, 2012 A cad drawing of the ally housing gasket is now in the CAD archive. I know you clever bods in-need will soon edit the dxf into a billet take off plate file p.s. It was a right fiddley thing to draw Quote Link to comment Share on other sites More sharing options...
