Area Representative Nick Bassett Posted November 8, 2022 Area Representative Share Posted November 8, 2022 Hi folks,Anybody got any tips for removing the KV6 TBs/inlet manifold from a VHPD head?The issue is there is a horizontal bar that sits on top the inlet manifold holding the IACV and the 4 recessed cap head bolts (holding this bar to the inlet) sit directly below a lip on the top of the cam carrier, so it seems impossible to access these cap heads, unless a cut down allen key is the answer? I'm concerned that using an allen key could damage them, making them even harder to remove!The annoying thing is, if recesses were cut into the side of the lip attached to the cam carrier, they could be made easily accessible from the top down.Pic attached, with two of the cap heads circled in blue (lifted from DVA website - thanks Dave!)

Leadership Team SLR No.77 Posted November 8, 2022 Leadership Team Share Posted November 8, 2022 I used to use a cut down hex key when I had KV6 bodies on my previous car. The pipe you're trying to remove is the air transfer pipe connecting the IACV to all four inlets.The photo you've linked to is most likely my current car, although Dave and the original owner had converted it to Jenveys by the time I bought it. Nothing wrong with KV6 TBs though.Stu. Link to comment Share on other sites More sharing options...
Area Representative Nick Bassett Posted November 8, 2022 Author Area Representative Share Posted November 8, 2022 Thanks Stu - I did wonder if the cut down allen key is the route to this.Another concern I have is, could I get enough purchase on these bolts using just an allen key? I guess being an alloy pipe, the bolts won't be too tight? Famous last words...!! Link to comment Share on other sites More sharing options...
TomB Posted November 8, 2022 Share Posted November 8, 2022 Are you sure you need to remove that rail to get them off the engine? I dont recall having to take it off to remove them. Ill try and remembe to have a look at mine later on. Link to comment Share on other sites More sharing options...
Area Representative Nick Bassett Posted November 8, 2022 Author Area Representative Share Posted November 8, 2022 Tom - yes I think so as the pipe masks one of the inlet bolts... will take another look tonight. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted November 8, 2022 Leadership Team Share Posted November 8, 2022 Nick, as Tom is touching on, is there any reason why you're trying to dissemble them on the engine rather than just undoing the (8?) bolts that anchor the bodies to the head and removing the complete assembly as one?

Area Representative Nick Bassett Posted November 8, 2022 Author Area Representative Share Posted November 8, 2022 Stu - I'm trying to strip as much off the engine as I can before I take it to DVA later this month. Link to comment Share on other sites More sharing options...
TomB Posted November 8, 2022 Share Posted November 8, 2022 Hi Nick, I can confirm I don't need to remove the IACV rail to get my KV6 manifold off. It's tight & takes some time, but I've only ever undone the nuts pictured below with an open ended spanner, and the other nuts and bolts with normal sockets or hex bit sockets.I hope this helps, cheers Tom Link to comment Share on other sites More sharing options...
Area Representative Nick Bassett Posted November 9, 2022 Author Area Representative Share Posted November 9, 2022 Thanks Tom - mine seems to have just cap head bolts fitted, meaning an open-ended isn't an option.I'll take another look at the weekend to see what's possible...CheersNick Link to comment Share on other sites More sharing options...

oilyhands Posted November 11, 2022 Share Posted November 11, 2022 Once apart, the ladder ledge can be modified to improve access to the top rail mount bolts and the underside of the rail can be modified to ease access to the two manifold bolts. I have done this a number of times.Oily Link to comment Share on other sites More sharing options...
Area Representative Nick Bassett Posted November 11, 2022 Author Area Representative Share Posted November 11, 2022 I was hoping you were going to say that Dave! Thanks. Link to comment Share on other sites More sharing options...
oilyhands Posted November 11, 2022 Share Posted November 11, 2022 I can make those mods when the engine is in bits..Oily Link to comment Share on other sites More sharing options...
Area Representative Nick Bassett Posted November 14, 2022 Author Area Representative Share Posted November 14, 2022 Progress update: after a bit of head scratching yesterday, I got my trusty Dremmel tool out and started gently grinding away the cam ladder shelf that was preventing access to the IACV tube bolts and it worked! Now have much better access to these and have managed to undo 3 of the 4! The last one is putting up a fight as it's rounded slightly, but I'm going to invest in some long reach hex bits for my ratchet and hoping that will do the trick in getting the little blighter out! It's currently being soaked in a cocktail of WD40 and Plus Gas...Any other thoughts on how to get this final one out gratefully received!
