I've had my hands full with this restoration and the dreaded work. I finished the valve cover job in the end and completed everything else I set out to do. The cams on both sides looked spotless and I couldn't see any wear on the lobes. I must've spent the good side of two hours cleaning all of the surfaces before putting the new valve covers on. All of the parts used were Nissan OEM direct from Japan. It's been over two months now since I did this job and it seems to have fixed the oil leak. D/S Cams A small pea-sized amount of Permatex RTV in the corners like the FSM states. New Valve Covers On Upper Plenum: Before Upper Plenum: After It was vapour blasted if anyone wants to know. I applied XCP Rust Blocker Clear Coat so it should stay nice and shiny for years to come. Separately, I had the strut bar and all of those small brackets (incl. PS reservoir and coolant tank) around the engine bay powder coated. Engine Bay I forgot to mention that I also replaced all of the old hoses with silicone hoses. The two hoses for the heater core were absolutely welded on! I had to break out the scalpel and use plenty of elbow grease. I also had a small oil leak around the oil cooler after a routine service using Castrol 5W-30 and a K&N oil filter (HP-1008). I followed the usual steps: primed the filter, applied a bit of new engine oil to the gasket and torqued to spec, so I'm not sure why it started leaking. Oil Leak I thought it might've been the oil cooler gasket so I replaced that. The photo is pre-replacement. Oil Cooler Gasket However, that still didn't fix it. In the end, I just bought a new Nissan OEM oil filter from eBay and put that on, which sorted it immediately. I can't say I'll be in a rush to buy another K&N filter anytime soon.

The Kebab Hopefully, it's heading off for sandblasting, welding and paint later this month but getting everything organised and lined up is proving to be difficult. I also removed the rotten sills as it just made sense to do it before it went in for sandblasting. There is an Instagram account I created to document the full restoration. Feel free to follow along at @thesuzukicappuccino. Edited April 14 by polaris 3 Quote Link to comment Share on other sites More sharing options...
davey_83 Posted April 14 Share Posted April 14 I was going to say it looks like the filter was defective and leaking from the seam sadly. I've used K&N oil filters in the past without issue, just one of those things I guess unfortunately. Well done on the hoses, powder coating, upper plenum and valve covers, all looks grand. 1 Quote Link to comment Share on other sites More sharing options...
polaris Posted April 14 Author Share Posted April 14 (edited) I forgot to mention the results of having the fuel injectors cleaned, which a few people might find interesting. I used Mr Injector UK at a cost of £141.48 (incl. delivery) for all six injectors. Fuel Injector Service Report As you can see, they were in pretty good shape to start with. However, there's been a noticeable improvement in fuel economy. I know correlation doesn't imply causation but I think it's valid to say in this case. The last six fill-ups have all shown above-average MPG. The green line is when they were cleaned.

RobPhoboS Posted April 15 Share Posted April 15 Funnily enough I had contacted him as well last week about having my set serviced but the price is more 😆 £22.50 per injector (includes full testing, spray analysis, cleaning internally, flushing the debris from within, final flow testing and balance matching the set) The kit of parts is installed at a separate cost, likely £15.48 for a 6 cylinder kit containing new upper and lower Viton seals. The return postage would be £15.00 within the UK. I still want to have it done, just as they've not been serviced before. Quote Link to comment Share on other sites More sharing options...

I just dug out the original email he sent me, and yeah, he has put his prices up. Still worth it though.

RobPhoboS Posted April 16 Share Posted April 16 For sure I still want them serviced just as they're nearly 20 years old 🥴 And I just want to make sure they're in good condition before another remap. I had presumed that it was going to be around £165-ish anyway, and he seems like a good one to use. 1 Quote Link to comment Share on other sites More sharing options...
