oilyhands Posted January 3, 2019 Share Posted January 3, 2019 I would match the TBs, the higher port line definitely helps airflow. 45mm TBs will be too large and cost you some torque. You dont need too much contact area for the top of the port, 3-4mm is enough, just make sure you use the right gasket and that it also matches the inlet port shape of the head.Oily Link to comment Share on other sites More sharing options...
p.mole1 Posted January 19, 2019 Author Share Posted January 19, 2019 It fired up eventually once I realised the spark plug leads were wrongly positioned on the distributor cap, the huge flame out of the throttle body give it away. I was running very lean but I haven't put Oilys engine map in yet and I only had it running in the garage to check for leaks.My water rail is a poor fit and used to leak it needs either bending or bit grinding off the mounting point on the head. Since I've just had it powder coated I tried running a bead of RTV onto the gasket bolting it on loosely waiting for it to cure then bolting it down and it seems to have worked.I'm quite surprised how it ticks over you would think it had standard cams in, should have gone for something wilder?

p.mole1 Posted January 27, 2019 Author Share Posted January 27, 2019 It's all in and ready to go! just need some dry salt free roads to give it a test. I'm expecting to need clean underpants after the test ! . The Radtec radiator fitted a treat and actually allows the nose cone to fit easily for the first time Link to comment Share on other sites More sharing options...
p.mole1 Posted January 27, 2019 Author Share Posted January 27, 2019 Luckily the excellent engine I bought from Nick Basset came with the rather nice latter cam cover which cured my oil leak Link to comment Share on other sites More sharing options...
revilla Posted January 27, 2019 Share Posted January 27, 2019 Good luck! Interested to see how it goes. I'm sure you'll finally be happy with it. The VVC mechs off that head are now all built up and timed up on my spare engine thanks Link to comment Share on other sites More sharing options...
p.mole1 Posted January 28, 2019 Author Share Posted January 28, 2019 Glad the VVC mechs have gone to a good home, their can't be many new unused ones knocking about. Took the car out for a quick run today just to check everything, no coolant or oil leaks. It seems to go ok and really seems to pick up at around 5000 rpm but I couldn't open it up, will have to wait for some decent weather. Link to comment Share on other sites More sharing options...

Leadership Team SLR No.77 Posted January 31, 2019 Leadership Team Share Posted January 31, 2019 Re: the water rail.Fit the rail with a new gasket and a thin bead of sealant (Loctite 5926) on each side of the gasket, and fasten up tight at the gasket end ... but do not tighten the bolt that secures the small support tab at the forward end. When it's located at the gasket end check the space behind the support tab and use a suitable washer to keep the tab spaced out from the head. There's generally a small gap, I've yet to come across one where the support tab is hard against the head after tightening the gasket face.Guaranteed not to leak :)Stu.

Wrightpayne Posted January 31, 2019 Share Posted January 31, 2019 I had to bend my water rail as the front tab was hard against the block and holding the flange off. Once bent never had a leak and as Stu noted I did need a washer too after tweaking it!Another thing that can cause leaks is the two flange bolts bottoming out in the head. A washer may suffice or shorten / replace the bolts.Ian Link to comment Share on other sites More sharing options...
p.mole1 Posted February 2, 2019 Author Share Posted February 2, 2019 Hi Ian,My water rail was the same as yours, i didn't want to bend mine as it had just been powder coated. It seems leak free, the RTV seems to have done the trick Link to comment Share on other sites More sharing options...
p.mole1 Posted February 12, 2019 Author Share Posted February 12, 2019 Took the car out for a run today, but cold track day tyres and and damp roads are not a good combination.I couldn't give it more than half throttle without loosing traction. Hopefully I will have my Quaiffe diff built up and in by March. I hope to have it on a rolling road by then. Link to comment Share on other sites More sharing options...
revilla Posted February 12, 2019 Share Posted February 12, 2019 Well at least that sounds promising. Link to comment Share on other sites More sharing options...
p.mole1 Posted February 13, 2019 Author Share Posted February 13, 2019 Went out today, dry roads and it all was going well, managed to give it full throttle until I developed a huge misfire. I had no tools and had left my mobile in the garage! Managed to limp back 10 miles on 3 cylinders. Turns out I was expecting too much from the Magnecor leads and one popped off no 4 cylinder. I need to get a set of leads 10 mm longer. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted February 14, 2019 Leadership Team Share Posted February 14, 2019 Just the plug 10mm longer or the complete lead? If it's the complete lead you really need a little more slack than that!Stu. Link to comment Share on other sites More sharing options...
p.mole1 Posted February 17, 2019 Author Share Posted February 17, 2019 New radiator leaking! not impressed it has a very small pin hole/porous were the temperature switch is welded in Link to comment Share on other sites More sharing options...
PROBE2 Posted February 17, 2019 Share Posted February 17, 2019 Is that a new radtec radiator? Sorry to hear that, I bought one same time as you so will check mine in particular around the temp switch Link to comment Share on other sites More sharing options...
7 wonders of the world Posted February 17, 2019 Share Posted February 17, 2019 Alicool http://www.alicool.co.uk/ Sadly Radtec seem to suffer from a lot of these problems judging by the number of similar posts - not sure how well new units are pressure tested prior to dispatch Link to comment Share on other sites More sharing options...
p.mole1 Posted February 18, 2019 Author Share Posted February 18, 2019 Thanks alloy radiators do seem to have some problems! it's a tiny leak but it shouldn't have one and it could get worse. Also my Accusump has failed yet again. When it works it's a good system however the pressure switch which is set to 35 psi keeps failing. This one lasted probably less than 100 cycles!The switch cost £102 on closer inspection it is just a 1/4 NPT oil pressure switch and they are just not designed to handle the current from a solenoid and the contacts are failing. I am hoping Merlin Motorsport will refund me and I am going to use an adjustable oil pressure switch and run it through a relay to take the load off the switch contacts, hopefully that will fix the problem.

p.mole1 Posted February 19, 2019 Author Share Posted February 19, 2019 Not impressed with the Accusump switch, I cut it open and the contacts have burnt out. Link to comment Share on other sites More sharing options...
Steve Cragg Posted February 19, 2019 Share Posted February 19, 2019 Also had a problem with my Radtec rad but to be fair to them they responded very well. Sent me a replacement immediately and I used the packaging from the replacement to return the damaged rad.Obviously prefer not to have the problem in the first place but couldn't fault their handling of it.Steve Link to comment Share on other sites More sharing options...
elie boone Posted February 20, 2019 Share Posted February 20, 2019 P.M.1 is that the EPC system ? i had it on a Ultima and never had a problem with it. Link to comment Share on other sites More sharing options...
p.mole1 Posted February 20, 2019 Author Share Posted February 20, 2019 Hi Elie, the Accusump is controlled by a solenoid which is switched via a pressure switch. The pressure switches are oil pressure light warning switches and are not designed to handle the load imposed by a solenoid and they burn out in a few cycles!

p.mole1 Posted February 26, 2019 Author Share Posted February 26, 2019 I've got say very disappointed by the response from the vendor about my Accusump switch which lasted one track day and couple of trips on the road. The switch cost over £100 and they seem to think because it has been used I cannot claim a refund!. Can you name and shame? I have returned them an email quoting the sale of goods act, lets see what happens Link to comment Share on other sites More sharing options...
