Gazzar Posted January 16, 2020 Author Share Posted January 16, 2020 But on the topic of oil pressure, where is the best place to plumb a gauge in? I know it's the filter at the moment, but that's before the bearings, so I'd never know if the cam followers are getting enough lube.

Use a tee in the filter housing port for the low pressure light switch, so you can use that switch and a pressure sender or capillary line. Holden Vintage and Classic sellthem and the instruments.

Snagger Posted January 16, 2020 Share Posted January 16, 2020 If you want oil temperature, and don’t mind spending a bit extra, then Holden also do the 3-in1 LR gauge with fuel in the bottom arc (where the charge light normally is) water temp on ones side and oil temp on the other. No need for a voltage regulator on that unit, either, as it’s incorporated in each individual gauge. I got one for about £80 in 2005. Smart way of getting the extra reading without mounting more round dials on the dash. But if you’re already going to fit a pressure gauge and don’t need space for other gauges, then a pressed panel to mount two small Smiths oil gauges would be a good solution, and I think you can get classic Smiths combined oil temp and pressure gauges. Not sure which turns out dearer, but they have it all on their site, and using the Smiths Classic gauges with black face and black bezel matches very smartly with the original Jaeger instruments.

Snagger Posted January 16, 2020 Share Posted January 16, 2020 Got a bit more expensive in the last 15 years, but worth it if the other gauges are past their best: https://www.holden.co.uk/c/hardware/gauges/other_gauges Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 16, 2020 Author Share Posted January 16, 2020 Ouch! I think having two gauges on another panel would look well. I'm a while away from that, so I'll not look at the lovely gauges for a bit. Quote Link to comment Share on other sites More sharing options...

They do whatever I want 'em to as I'm currently programming it it's the first prototype but I couldn't resist posting. 1 Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 16, 2020 Author Share Posted January 16, 2020 Sounds Wizard. I think if I get the engine running, I'll be happy enough. I've Saturday set aside to finish the clean up. Hopefully my mate of a mate will steer me in the right direction next week, and I can start the rebuild. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 18, 2020 Author Share Posted January 18, 2020 More cleaning today. Crankshaft first. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 18, 2020 Author Share Posted January 18, 2020 Etcetera. I remembered to remove the pivot pilot bush. Using an old pinion and some scabby grease. I was surprised when it actually worked. I had to break up the bush to get the pinion to complete the removal. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 18, 2020 Author Share Posted January 18, 2020 I cleaned up the conrods and the pistons next: Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 18, 2020 Author Share Posted January 18, 2020 Takes quite a while to do this. I also broke 2 oil control rings, which are tricky to remove. Piston 3 oil control ring was stuck into the groove. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 18, 2020 Author Share Posted January 18, 2020 I really don't know what's worn out, or what's good for another 50,000 miles. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 18, 2020 Author Share Posted January 18, 2020 I also cleaned the cam followers and tappets. I think this one is worn: Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 18, 2020 Author Share Posted January 18, 2020 The rocker gear is all a bit marginal, I think. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 18, 2020 Author Share Posted January 18, 2020 The pads on the rockers show wear. And I'm not convinced by the bushes. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 18, 2020 Share Posted January 18, 2020 The crank journals looked like it is probably due a grind. Pistons don't look terrible, rings obviously replace.... Check the pads on the rockers, but also need to disassemble to check for scoring on shaft/Rockers. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 18, 2020 Share Posted January 18, 2020 Ah, pics, rocker pad looks pretty good to be honest, as do the bushes. 1 Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 18, 2020 Author Share Posted January 18, 2020 The rocker shaft has significant witness marks where the rockers were. I think I'll replace the rockers and the shaft anyway. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 18, 2020 Author Share Posted January 18, 2020 The crank feels really smooth, mirror like, but the photos don't reflect that, I think there's particles in the light oil I've sprayed on the journals. I hope to get a more experienced opinion on Tuesday. If it were me, I'd stick new shells on, and call it fine. But I'm of Yorkshire Scots descent, so have a tendency to exhibit tight fistedness. I know of this tendency, so try to compensate. 1 1 Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 18, 2020 Author Share Posted January 18, 2020 The valves have a lot of deposits. Is this normal. I took two out, and started to clean, but ran out of time. I think I'll replace the valve with deposits. If they aren't mad money, I might do both. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 18, 2020 Share Posted January 18, 2020 Yes, being coked on the back is normal. Stick them in a pillar drill and clean them up with wire brush, emery, whatever you like Quote Link to comment Share on other sites More sharing options...
