robin craig Posted February 12, 2012 Share Posted February 12, 2012 I was speaking with someone yesterday who stated that there were variations in the design of the J60. I am told that some had dry liners and some did not and there is a way to tell the difference by the engine serial numbers. Can anyone shed some light on this subject?

0 Manylandrovers Posted September 10, 2014 Share Posted September 10, 2014 Looks like it will have to be banisters; no-one does individual pistons anymore.... does anyone know the part number of the thick exhaust valves that a j60 has? regards, Andrew Quote Link to comment Share on other sites More sharing options...
0 Manylandrovers Posted October 13, 2014 Share Posted October 13, 2014 Well, I managed in the end to get 2 Pistons from David Manners and a second head from the jag spares day at the NAC. Not a bad day in all! Gasket from xmod and the rebuild can start:-) Quote Link to comment Share on other sites More sharing options...

0 datadawg Posted March 13, 2015 Share Posted March 13, 2015 I am buying a Fox now in UK and after reading this thread, my excitement of purchase has now turned to trepidation. I plan to having the Fox completely overhauled before importing it to US, which will include engine removal for painting, etc. Is there anything that should be done/serviced/checked regarding the engine (other than fluid changes), to be "safe", since it's going to be out and easy to do? The work will be done by Baz at trackfix. Quote Link to comment Share on other sites More sharing options...

0 teletech Posted May 27, 2015 Share Posted May 27, 2015 I found the following article very interesting in considering the 4.2 engine. It would seem that the latest block and crank should be used and rebuilt carefully if one must run a petrol motor. Careful consideration of bearings might help with the oil starvation that seems to cause so many thrashed blocks. http://www.jagweb.com/aj6eng/xk-engine/index.php Quote Link to comment Share on other sites More sharing options...
0 Grasshopper Posted May 27, 2015 Share Posted May 27, 2015 Thanks for posting, interesting article. It does explain why these engines are quite fragile, especially in an AFV (for which they were not designed or intended). Running in that sort of an environment can't have done it any favors, I can see a few reasons (other than to run on low grade fuel) why they were de-tuned. Made me think maybe I ought to prioritize an engine service! Quote Link to comment Share on other sites More sharing options...
0 teletech Posted May 27, 2015 Share Posted May 27, 2015 I was planning on putting a 4.2 back in but it really gave pause thinking about all the potential failure points. It actually seemed like decreasing the displacement might have been a better way to do the de-tune as some thicker cylinder walls would have helped things but I suppose Jag would have had to make some investment for that to happen. If one wanted to spend a lot of time and some money one *could* build one that had a reasonable expectation of a long life but it would take some doing: mid-80s crank with polished gallery bores and chamfered holes , late block (carefully magnifluxed), new pistons, flow the head, balance everything, add the groove in the crank journal bearing, carefully selected thermostat (what a thing to have to worry about)... what have I missed? I guess it's a reminder to change oil frequently and verify your rust inhibitant in your coolant. I have used water-wetter in the past in some road-going vehicles and it seems to help. And of course to have a recovery plan! Quote Link to comment Share on other sites More sharing options...
0 datadawg Posted December 5, 2015 Share Posted December 5, 2015 Photos of my Fox's engine before and after OH. I can see the ribs but that's the extent of my expertise on identifying it. I believe it is not the original engine. Any ideas from the learned what type it is? Quote Link to comment Share on other sites More sharing options...

Careful consideration of bearings might help with the oil starvation that seems to cause so many thrashed blocks. http://www.jagweb.com/aj6eng/xk-engine/index.php Are they really that bad in privately owned CVRT's though..? Certainly the 5.9's are more robust, but provided you're not wringing it's neck and you watch oil levels etc is it that big a problem? At the end they had all been further detuned to 175bhp I believe... I have sold a few of these engines recently and they've not all been trouble free. One of my customers managed to put a two inch hole in the block, but he had spent the last 2 years bouncing it off the limiter - I declined a refund!! By all means if you have to rebuild an engine, you may as well do it to the best possible standard, but if it ain't broke don't fix it!

0 Braillescaledave Posted December 17, 2015 Share Posted December 17, 2015 The J60 was also fitted to some 'R' series Dennis fire appliances- Not a great success according to my old dad- said they accelerated well, just couldn't keep it going- Not surprising really, 16t full-up fire engine being a somewhat different kettle of fish...

I was speaking with someone yesterday who stated that there were variations in the design of the J60.
I am told that some had dry liners and some did not and there is a way to tell the difference by the engine serial numbers.
Can anyone shed some light on this subject?
