Gazzar Posted September 24, 2019 Author Share Posted September 24, 2019 Definitely cam pulley. Now, the question is; why has it moved? Quote Link to comment Share on other sites More sharing options...
Gazzar Posted September 24, 2019 Author Share Posted September 24, 2019 It's actually about 1mm out of alignment, I think. Hopefully it's a loose bolt. I've just taken the IP off, so will look at that age I've posted the pump off for a performance tune. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted September 24, 2019 Share Posted September 24, 2019 Can only be a loose pulley, really... or perhaps snapped cam, but let's not go there yet Quote Link to comment Share on other sites More sharing options...
Gazzar Posted September 24, 2019 Author Share Posted September 24, 2019 Thanks Bowie. It was running really well, when I decided to investigate (excluding the knock) so I hope, very much, that you are wrong on the broken cam front. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted September 24, 2019 Share Posted September 24, 2019 Stranger things have happened.... saw a cam which was snapped one cylinder in, allowing it to still drive the rest of the camshaft running the engine perfectly, albeit with a few cylinders that had slightly retarded cam timing. Made a horrid noise though Anyway, I am quite sure it is just a loose pulley Quote Link to comment Share on other sites More sharing options...
Gazzar Posted September 24, 2019 Author Share Posted September 24, 2019 Errrrrr. No. This is unusual. The bolt was finger tight, or even loose. But there was worse to come. Quote Link to comment Share on other sites More sharing options...

western Posted September 24, 2019 Share Posted September 24, 2019 That would create a knock, what's the cam like, I replaced my cam with a new one during my rebuild, still have the old one here if you would like it. nothing major wrong just wanted to fit a new one in new bearings, its actually the same cam as in the 2.5n/a & TD engines. you can get a gear from Turner Engineering https://www.turnerengineering.co.uk/err-666-pulley-camshaft-c2x20634827 it's not madly expensive either imho.

Gazzar Posted September 24, 2019 Author Share Posted September 24, 2019 Thanks Western, for the offer. I'm reluctant to take the head off, to be honest, I fear that I might start rebuilding the engine! You do have to take the head of to do the cam shaft, right? I'll inspect the keyway in a minute, and if its okay, then I'll leave it be. Even if I Loctite it into the keyway, I should be all right. Big turner order coming up. 1 Quote Link to comment Share on other sites More sharing options...
Gazzar Posted September 24, 2019 Author Share Posted September 24, 2019 Is there a disco 1 parts manual anywhere on the internet? I've the defender one, can't find the disco version. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted September 24, 2019 Share Posted September 24, 2019 Nasty, would have broken because the bolt was loose. If the cam is OK (probably if you ask me, the cam is much harder than the pulley) then it could be a very lucky find.... 1 Quote Link to comment Share on other sites More sharing options...

Gazzar Posted September 24, 2019 Author Share Posted September 24, 2019 Thanks Western. I appreciate it. The keyway looks, not perfect, but okay. I'l loctite in the key when I do the job, some 660 should do the trick. Right, a BIG order heading Turners way. Quote Link to comment Share on other sites More sharing options...
steve b Posted September 24, 2019 Share Posted September 24, 2019 Apart from the keyway and the shaft diameter ( measure) I would look at the rear register face for the pulley on the cam and maybe check for run-out if you use the cam when you put the pulley on and torque it up , it looks like you have escaped a big strip down , so all good and change the oil seal ! cheers Steve b Quote Link to comment Share on other sites More sharing options...
Gazzar Posted September 24, 2019 Author Share Posted September 24, 2019 Good point, I need to order a dti and base. I've ordered a new thrust plate, hopefully that will set everything back to true. And seals and gaskets and all sorts. Not cheap gaskets but also wasn't paying jlr prices for gaskets, my God, they know how to charge!

reb78 Posted September 24, 2019 Share Posted September 24, 2019 This is why I was asking about loctiting these gears on to the cam and crank shaft in the defender forum recently. I am going to continue putting a little loctite on there - it prevents any movement i think. It shouldnt happen if the bolt is tight but I have seen threads like these occasionally and think loctite may help things stay put. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted September 25, 2019 Author Share Posted September 25, 2019 I suppose it's the fear of difficult disassembly, in a cramped space, that puts people off the idea. I'll be certainly doing it in future, mild Loctite, not the high strength stuff. And clean all blind holes with oodles of brake cleaner.

Mo Murphy Posted September 25, 2019 Share Posted September 25, 2019 Gaz, I have a good cam gear here which came out of mine when I changed the front end to Defender spec. Yours for the price of postage. Any good to you ? Mo Quote Link to comment Share on other sites More sharing options...
Gazzar Posted September 25, 2019 Author Share Posted September 25, 2019 Thanks Mo, I'm good. New is only £50, so went with that. I do have a spare engine, that, one day, I'll rebuild properly. Nowadays, I don't even have time to strip it down! One day. I'll do everything! Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted September 25, 2019 Share Posted September 25, 2019 👍 no problem mate, thought I'd offer as I know how the solution to these problems can add up ! Mo Quote Link to comment Share on other sites More sharing options...
Nonimouse Posted September 25, 2019 Share Posted September 25, 2019 Do you need a decent cover the for the chest? I have a spare you are welcome to, along with a 200tdi air box You could rebuild the damage by using a copper woodruff key and building up around it with weld... The cam/oil way issue is where, when the engine is thrashed within an inch of it's life, after spending 100k pootling about (imagine LR 90 with 1.667 T box and 205/26's doing 80 on the M5) it can move forward in the cam chamber(?)/ This then exposing an oil gallery at the rear of the engine (handily accessed by the core plug at the back) and the oild pressure drops through the floor Only fix is strip to block and drop down to the local engine guru to have new white metal bearings installed and line bored Quote Link to comment Share on other sites More sharing options...
