I’m guessing it’s either the pitch at which the valve guide has been honed, or the angle of the valve seat is off.... but I’ve asked for clarification

Yup, 4 degrees. And for those of you who are wondering what it means for the valve guides not to be concentric.... here’s a quick read https://www.enginebuildermag.com/2013/10/cautioning-on-valve-seat-concentricity/

A little, slightly annoying update. Yet again I’m having to redo work that I’ve already paid a pretty penny for. In the process of having the valve seats cut, Mitch has found that the Ferrea guides on the exhaust side that were installed by Roland Alsop were not machined correctly and were 4deg off concentric. Luckily there is no damage to my SuperTech valves (the joys of Inconel!)So another set of Ferrea valve guides are going in the exhaust side. I was hoping to be able to make Simply Japanese at the end of the month, but this unexpected discovery and associated delayed now makes that unlikely.

Well after getting fed up with 1st Direct Windscreens refusing to admit fault at incorrectly fitting my windscreen, I finally sorted another company to come to my workshop and reinstall my windscreen properly, with the Nissan upper windscreen moulding Annoyingly, I appear to have misplaced the little white block clips for the roof part of the side mouldings. Bloody annoying when that happens!

I wish I knew mate! So the heads are having their valve seats cut at the moment so should be with EPR beginning of next week. Then it’s machine for cam lobe clearance, debur, clean and assemble. After that, front of the engine goes on so it can be timed up. The turbine housings need porting and the hot side parts need ceramic coating. I was hoping to make Beaulieu, but I think that’s unlikely now

New Vibrant Ultra Quiet resonators turned up today... hopefully they’ll save my ears! A slightly unexpected purchase aswell. Saw these on a breaker near me and snapped them up! They need a refurb, but will add to what will eventually be a full Whiteline suspension package

Just noticed, over 5000 thread views in 18 months and over 1000 likes on the cars IG page since January! Wow! All I can say is thanks for the interest, and there’s plenty more stuff planned for the future.... but first things first, I’m looking forward to getting some seat time in the car and enjoying it!

Lower Plenum has now been ported, with the injector entry altered for better dispersion(you can see before porting on the right hand port and after on the left hand port) It's completely matched to the cylinder head ports for optimal flow. The heads have been shipped back to EPR and should be there on Monday for the valve seat cut and assembly

Time to let those 48P’s breath!

For any one who was looking to stay at the hotel but couldn’t due to availability, I’ve just cancelled my room for the night so there should be space

There’s s thought!

On the engine front, the block has had its final debur, clean and paint (not pictured) and assembly will start later today. A couple of interesting point of note: Oil Squirter: as you can see in the bottom pic, they’ve been blanked off. Why? Due to the coatings applied to the pistons, that spray of oil is not needed. That mean less parasitic drag on the internals and reduces windage and potentially less crank case vapours. Block oil restrictions: The OE press in restrictors have been removed and replaced with removable items (to assist any future cleaning should the worst happen) Freeze plugs: I was gonna smacked at how much junk was hiding behind them! Just shows how much cleaning is truly required on an engine rebuild

On a positive note, I got back rear brake calipers back from refurb. As I suspected, I had a couple of sticky pistons due to a build up on aluminium oxide. So after an ultrasonic clean and polish of the pistons, new set of seals they’re good to go I’m hoping, at some point next year, to sort my rear brembo conversion out, but in the mean time these will do

It’s part of the reason. The money would also be better spent on finishing the car at the moment, aswell as saving my passport stamp for a car related overnighter for later in the year.

...

I’m sad to say that I’m not going to make this. Substantial delays state side with my engine build mean I won’t get my engine delivered until a couple of days before the AGM, which simply doesn’t leave me enough time to have the car ready. As we only have one other car, I can’t leave the Mrs and the kids without transport for a weekend. I’m going to push on and have the car back on the road for Simplt Japanese. I’m super gutted about not being able to show those who voted for my car at COTY at the clubs AGM, especially given the 30 year anniversary.

Nice find gaz

I don’t know if you’ve got one on stock Jim, but would it be worth approaching an AC company to see if they can reproduce them?

Sorry, I misread your original question. I’m using a Wix filter that has one built it. However, as I thought more about the bypass issue I realised a couple of things. 1) I’ll be changing the filter every 12 months or 3000 miles anyway, which isn’t going to be enough time to block a filter to the point where I’d need the bypass valve. 2) if I do block a filter that quickly, the engines likely toast anyway so a bypass valve wouldn’t offer me any extra protection

Excuse the crude drawing In short the OEM oil tree has been replaced with a BDE oil tree plate. Hot oil is fed along -10 line to the Improved Racing remote filter head. That will be mounted near the AC dryer. I’ve removed the OE cooler lines to give me more space While the engine warms up, oil is passed through the filter and returned back to the engine bypassing the oil cooler. Once up to 185F, the thermostat directs all the oil through the filter and to the oil cooler. From the cooler, back to the IR filter head and back to the engine.

So I’ve been cracking on with the to do list. Firstly I’ve ordered a few parts. The Improved Racing thermostatic oil filter relation kit and a pair of Vibrant Ultra Quiet resonators (which will replace the useless LongLife resonators in my H pipe). I think the only bits I need to order now are a new oil coolers, some dash 10 braided hose and some AN10 fittings for the remote oil filter and cooler lines This evening I also finished my first attempt at retrimming some interior parts, the rear quarter panel vinyl sections. I don’t think they came out too badly consider my inexperience. The colour is a tiny bit darker and the faux texture differs slightly, but it’s close enough that I doubt anyone would notice
