paulob1 Posted July 23, 2014 Share Posted July 23, 2014 She has always run very close to boiling but is now overstepping the mark and overheating...first going to clear out the water and wash her through to make sure we have no silt in the system...the water pump appears to be working fine, the thermostat is removed, we tried that first...but I will replace that.. next going to remove the radiator and give it a good wash out and thorough clean...and remove the 50 years of grunge that has built up on it, hopefully that will help too... but is there anything peculiar to the ferret that I SHOULD LOOK AT TOO. The engine runs sweet and is not being worked hard...so doubt it is anything there but any suggestions gratefully accepted from you more knowledgeable sorts out there..

Richard Farrant Posted July 23, 2014 Share Posted July 23, 2014 When in service this problem often came up and it was usually a build up of debris and dust drawn into the engine compartment, mixed with a little oil and coating the engine side of radiator core.

sirhc Posted July 23, 2014 Share Posted July 23, 2014 Have you cleaned out the relief valve that exits the hull on the opposite side to the exhaust? These are often blocked. Quote Link to comment Share on other sites More sharing options...
antar Posted July 23, 2014 Share Posted July 23, 2014 How do you know that the water pump is working can you see coolant moving ? Have seen Champ water pumps where the impellor has corroded away due to just having water in the system, all appears good from outside but coolant is not being displaced.

MiketheBike Posted July 24, 2014 Share Posted July 24, 2014 Head gasket on the way out? Just resolved an issue on the 101. Coolant gas test was negative, no water on oil, leak down test negative, but under load/speed coolant was being pumped through the rad cap. Head gasket was corroded at one end of the head at the water jacket and pressure from cylinder was being pushed into coolant. Apparently not uncommon on a rover V8, but mabe worth considering on the B60? Quote Link to comment Share on other sites More sharing options...
griff66 Posted July 24, 2014 Share Posted July 24, 2014 read my thread on ferret cooling probs turned out to be, after lots of other options tried, to be the valve that sits on top of rad not allowing system to pressurise properly Quote Link to comment Share on other sites More sharing options...
paulob1 Posted July 25, 2014 Author Share Posted July 25, 2014 will take out rad and give her a clean and also check this relief valve....thanks guys Quote Link to comment Share on other sites More sharing options...
paulob1 Posted August 25, 2014 Author Share Posted August 25, 2014 well removed rad...and found the problem... I had wrapped the exhaust of the engine to try and queiten it as the small connecting pipes simple from no seal at all. however modern wrap is totally useless. it had borken up and spread itself with oil and other contaminant all over the radiator so virtuall blocking it off. a couple of hours cleaning and she is running sweet not overheating and all is fine...now i have to try and find some connecting pipes that are a good fit instead of these ones..anyone found a suitable solution for this...wondering if I cant make up some sort of flxible pipe connection... anyone else found a solution to this Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted August 25, 2014 Share Posted August 25, 2014 You may be able to reclaim the two connecting pipes as I have in the past when new ones were n/a. Clean up the rolled ends and run braze around them then file around them until a sliding fit in elbows, at least they will not rust now.

griff66 Posted August 25, 2014 Share Posted August 25, 2014 scaffolding poles are a very similar diameter yes i know they are alloy or bannisters can sell u some new ones i might even have some floating around! Quote Link to comment Share on other sites More sharing options...
Cold_War_Collection Posted August 25, 2014 Share Posted August 25, 2014 We had two Stainless Steel, heavy wall tube section cut to size. We found when they heated up, they expanded almost perfectly to a sung fit. Cheers Nick CWC Canada Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted August 25, 2014 Share Posted August 25, 2014 As there is a small amount of flex in the engine and transmission mounting the tubes have the swaged ends to allow for movement. If too tight an elbow can crack. I seem to recollect the very early Ferrets had steel tubes with parallel shouldered ends, and think they were changed due to damage of elbows.

paulob1 Posted August 26, 2014 Author Share Posted August 26, 2014 thanks Guys but I think i am going for the flexible pipe route....I can then fix them tightly at each end (somehow yet to be determined) and then fix the flexible hose in between to allow for movement...

griff66 Posted August 26, 2014 Share Posted August 26, 2014 think i would be inclined to get standard parts in better condition when in good condition and when hot the seal is adequate especially for a engine that sits behind crew. Quote Link to comment Share on other sites More sharing options...
cooler07 Posted August 26, 2014 Share Posted August 26, 2014 Here's what I made for Saladin, should work for Ferret if you can find flex pipe that's small enough. Quote Link to comment Share on other sites More sharing options...
paulob1 Posted August 27, 2014 Author Share Posted August 27, 2014 yes Griff sort of agree and the space is very short for flexible pipe....it really needs a compression pipe, that when hot expands easily into the gap and sealing it a bit better...will try to get some new ones and have a go at refitting them...
