Some trucks have belt driven oil pumps now. MAN, I think, are one. Apparently they are reliable. Not convinced, but I suspect that these new ideas do work well. On version 2.

Just another engineering failure on the puma. I heard a horror story about a low miles defender, only 20k miles, where the main box spud shaft splines failed completely. 20k miles! So, this doesn't surprise me at all.

Well, I've one in. Doing a little bit of cleaning as I go, so it's taking time. One of the issues is that the bush curl on one of the parabolics off true. No surprise that the bush failed, really.

If the tube pivots freely in the plastic, would it have any impact?

I'm going whole hog on the 109. I'll be rebuilding the chassis at some stage, so changing the bush holder, if it gets worn, is no problem. So, remove all the old bush, insert the two plastic bits, sandwiching a few shots of grease, inner tube, tighten up shackles, done? Do they have to be tightened loaded like the genuine?

Thanks nick. I'll try standard, see how they stick the abuse!

I'm going to fit some poly bushes to the 109. I've tried the original type and they failed, so I'll try these with the parabolics. I was watching a YouTube video about fitting a washer/flange to the shackle plate to stop the side of the bush from eating itself on the shackle and it kind of makes sense. If you fitted poly bushes did you do this? Did it help, or did your shackles live happily with the bushes?

Thanks Nick, your blog is an inspiration, I must go through in detail. G

I'm wondering if this is the best route to getting the snorkel fitted. Can it connect to a defender pipe? The snorkel will be exiting, defender style, on the drivers side, RHD. It's a defender turbo, and I'd planned on putting the air filter somewhere on the passenger side wing.

The crazy thing is that it can't cost that much more to get the parts made right first time around.

I've bought a new chest, Turners have them for reasonable money. But the air box? I'd be interested in that. Any photos?

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!

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.

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!

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.

Is there a disco 1 parts manual anywhere on the internet? I've the defender one, can't find the disco version.

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.

Is it new cam time?

Much worse.

Errrrrr. No. This is unusual. The bolt was finger tight, or even loose. But there was worse to come.

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.

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.

Definitely cam pulley. Now, the question is; why has it moved?

You sound like my wife. Thoughts like that result in a Hyundai Rio sitting in the drive.

You are right - replace all. I did think of using the heater, but I LIKE my heater - it works. I think I'll do a tdi cut, and use the tdi inner plumbing parts. That's a fairly well used route and should be easy enough to seal up.
