SiC Posted January 28, 2018 Author Posted January 28, 2018 Video proof. For all we know you could of just had the electric drill on it!Funnily enough I was trying to figure how I could mount my phone to record the journey. Might see if I can get a phone mount.
SiC Posted January 28, 2018 Author Posted January 28, 2018 A really boring video that you probably don't want to watch on the oil pressure and how it is now. It has a weird spike around 1250rpm where it peaks and then drops down. Maybe the valve is a bit sticky at the moment? [Video]
Guest Hooli Posted January 28, 2018 Posted January 28, 2018 Probably about the speed the relief valve opens as pressure increases from the pump? richardthestag 1

Six-cylinder Posted January 28, 2018 Posted January 28, 2018 The oil pressure shows a little lower than mine, but not so low as to not drive it. Just get on and use it, build up your confidence with it and you will start to enjoy it. richardthestag and SiC 2
busmansholiday Posted January 28, 2018 Posted January 28, 2018 Quick blast around the M32, M4 and M5 will soon get your confidence back in it.
SiC Posted January 28, 2018 Author Posted January 28, 2018 Decided to get this rheostat out and give it a clean. Required taking the rev counter out for access and unfortunately some of the flaky dash paint came off. If this behaves itself this year, I may treat it to a dash repaint next. Contacts were filthy but it looks to be an original part. Insides weren't much better. Spent half hour giving it a good clean up with contact cleaner, a Dremel, wire brush and a bit of sandpaper. In putting it back together and looking how it rotates, I realised that last night failure wasn't a failure. It was the car fixing itself! Turns out the dimmer knob goes a distinctly old British car way - not what you expect. It goes minimum brightness to maximum brightness, hit a detent and then off. I.e. if you turn up to max brightness and go past that, it turns the dash lights off. How bizarre way of working! Actually it's not really, looking at how it works, it's much easier to design the mechanism having an off position like this. Basically the spec seemed to be written by an engineer for ease of mechanical design, rather than a designer for ease of use. mat_the_cat, danthecapriman, richardthestag and 3 others 6

Just get on and use it, build up your confidence with it and you will start to enjoy it.It used to be around 60-65psi before I changed the oil+filter+pressure relief spring. If I don't get a higher pressure on the next oil change, I'll probably put a shim on the relief valve to boost the pressure a tad. Six-cylinder 1
Sigmund Fraud Posted January 28, 2018 Posted January 28, 2018 Just make sure that increasing the oil pressure won't lead to premature failure of the oil pump and timing chain... SiC 1
SiC Posted January 28, 2018 Author Posted January 28, 2018 Just make sure that increasing the oil pressure won't lead to premature failure of the oil pump and timing chain...The great John Twist reckons that one shim to boost it to 70-75 psi is ok. If I get 60-65psi on the next oil change though, I'll just leave it be. I have noticed since the oil change & filter the pressure builds up nearly instantly and no tapping on startup. Not sure if the original filter didn't have a anti-drainback valve or the new pressure relief valve fixed it.
purplebargeken Posted January 28, 2018 Posted January 28, 2018 Anti-drain back filters required for small Triumphs too.

Royale80 Posted January 28, 2018 Posted January 28, 2018 Old cars do need to be driven, lay ups causes all kinds of misery. I agree. Just been out in the Royale for a 40 mile jaunt-to visit the MIL-I use it one week-the Senator the other. Seems to keep them running. Steve
PhilA Posted January 28, 2018 Posted January 28, 2018 Psh, that's not a weird spike. That's normal for oil that's a bit too thin and a gauge that's been sitting up for ages. Bourdon gauges never move smoothly by themselves slowly anyway. That's why you were tapping it at the end, do you realise... Pressure relief is a bit sticky. Drive it about, change the oil when it starts to turn color and enjoy the car. Phil SiC 1
SiC Posted January 28, 2018 Author Posted January 28, 2018 Next step is to give it a bit longer run locally (10 miles?), then a trip to the garage near work for the tank and slightly stripped wheel stud to be changed. If it's behaved itself on that, trips into work. Unless I get another car sooner, then the MGB will be put into the garage until the spring/summer. Sigmund Fraud 1

xtriple Posted January 28, 2018 Posted January 28, 2018 I changed the oil pressure relief valve and spring on mine and the oil pressure became annoyingly low. Put the old ones back and it was fine. Not sure that the new ones from Moss are any cop to be honest. It does look like the pressure is building nicely then the relief valve is kicking in too early. I was about to say the rheostat is doing what it should but you got to it before I could share my profound knowledge SiC 1

Perfect for me to go for a potter around country roads north of here, after work in the evenings.

I was about to say the rheostat is doing what it should but you got to it before I could share my profound knowledge Good to know. Possibly this new spring isn't as strong. I've changed too many variables to know what might have caused the drop in pressure now. The new spring was definitely longer though - but I guess doesn't mean the strength was more.
