dodgedavidson Posted February 20, 2021 Share Posted February 20, 2021 I'm looking for a VVC timing belt cover, the inner part that goes up against the block. Mine has split and is rubbing against the pulleys. Rover part number is LJR104760. Anyone have one lurking around? Link to comment Share on other sites More sharing options...
revilla Posted February 20, 2021 Share Posted February 20, 2021 These really are hen's teeth now, largely on account of scrapyards' habit of snapping them in two when removing a head to sell the head and block separately as they can't be bothered to undo the crank pulley and take off the lower belt cover!I've been trying to get hold of them for engine builds for a long time now. I've had them on back order with Rimmer for I think about three years ... they keep sending me updated delivery dates but nothing ever appears.Similarly with all the usual suppliers, nobody has them in stock.They do occasionally come up on eBay, very occasionally new but mostly used, and even decent used ones come up very infrequently and fetch very high prices now.It is possible to cut down a non-VVC part to make something quite workable. Non-VVC covers are still a little easier to obtain for now. I think for my next builds I'll try to make up a template to cut to. Beware there were definitely two different non-VVC ones and one is quite a different shape at the bottom and the bolt holes don't line up, so you need to start with one that looks the same shape at the bottom end.Shooting myself in the foot here but ... There's one on eBay right now. Going for the best part of £70! If it's still up for sale when I get onto the next build I'll have to buy it despite the price, but since I have sat here mopping up most of them that come up for a while if you want to jump in ahead of me I'll give you a head start: https://www.ebay.co.uk/itm/MGF-MG-TF-VVC-160-147-TIMING-CAM-BELT-COVER-REAR-SECTION-/353383567618?_trksid=p2349624.m46890.l49292Cheers,Andrew Link to comment Share on other sites More sharing options...
dodgedavidson Posted February 21, 2021 Author Share Posted February 21, 2021 Thanks Andrew, I hadn't seen that, you are very generous sir, I've bought it. Like you say very difficult to find but I've only been looking for a couple of weeks. I cleaned up mine yesterday and thought I might be able to put a plate on the back across the crack (at the top 12 oclock) but then realised it was also cracked but not broken yet at the 3 o'clock position, very wobbly and the pulleys have scored the backplate. Next idea was modifying a non VVC one, the screw holes look to be in the same place but I wasn't sure if the cross section profile was the same. Should I not use it for any reason I will pass it to you for the same price. Cheers, Roger Link to comment Share on other sites More sharing options...
revilla Posted February 21, 2021 Share Posted February 21, 2021 I was wondering about cutting down a non-VVC cover for a while. In the end I bought a non-VVC belt cover to play with and convinced myself it wasn't possible because the bottom section of the cover was so different. I'd got one of these:What I needed was one of these:Recently I was sent a VVC engine for rebuild which already had a cut-down non-VVC cover installed and it was a neatly done job and worked well, so it's definitely a possible "Plan B" for the future.For the longer term I'll need to find a solution anyway so letting one slip away only brings the inevitable forward a bit Link to comment Share on other sites More sharing options...
Mechanical Moz Posted February 21, 2021 Share Posted February 21, 2021 You could have a good one scanned and then 3D print replicas, it may be prohibitively expensive though. I threw a perfectly good one away a few years ago, it didn't even cross my mind that it would be something that would be difficult to obtain sorry.

dodgedavidson Posted February 21, 2021 Author Share Posted February 21, 2021 Andrew,I'm making a hopeful assumption, that once I've converted to non VVC the standard front cover (without the VVC bulge) will fit, is that the case? Link to comment Share on other sites More sharing options...
revilla Posted February 21, 2021 Share Posted February 21, 2021 Yes, it will. You'll still need the VVC inner part (which we've been discussing) to fit around the blanking kit, but yes I'm pretty sure the flat "lid" should then fit fine. Link to comment Share on other sites More sharing options...
rj Posted February 21, 2021 Share Posted February 21, 2021 Andrew: The simple solution is to have it made from carbon fibre :-p The problem with 3D printed items is that most of them don't last very long, and one thing I'd not like to detoriate intot the cam belt is the cover.

revilla Posted February 21, 2021 Share Posted February 21, 2021 Hi Regin,Yes I agree, and I think when I looked at it before, most of the 3D printing materials available wouldn't stand up to the heat of being bolted to the head very well?Carbon fibre sounds like they might be a bit expensive!I think for now making up a template to allow me to cut down non-VVC covers reliably to a repeatable pattern should suffice.When they run out, then it might be time to look at fabrication (if there's still demand). Same for oil pickup pipes etc.Cheers,Andrew Link to comment Share on other sites More sharing options...
rj Posted February 21, 2021 Share Posted February 21, 2021 You could mill a spacer from alloy and have flat sheets simply cut to shape. The outer shape of the spacer should be like the shape of the current cover. And then just be a thin wall except where bolts go in to fix the flat sheets. I've been thinking of doing something like that - just because I can ;-) Link to comment Share on other sites More sharing options...
