Pete There's loads of ramps for sale around me on the old facebook. Quite cheap too. I may put some "stuff "in until i get to have a proper look.

Indeed it does, the PO of my car must have mixed the two as the block and rad were clogged. It was one of the reasons I decided to strip the engine and rebuild it correctly. Many cock ups were found and the effort was worth it. Iain Link to comment Share on other sites More sharing options...
Paula Posted November 5, 2023 Author Report Share Posted November 5, 2023 (edited) I've changed the oil and added some SIP (god that stuffs thick!). It's a lot quieter now but i'm still not happy about the diesel engine type growl. There was some metal in the filter bowl, like fillings. Not much, but that's a worry too. He was very smokey when started after the oil change. That got a lot better, but didn't go away after a run. I'm still not confident enough to use him for longer journeys.

Pete Lewis Posted November 5, 2023 Report Share Posted November 5, 2023 smokey after an oil refill is the excess oil going down the valve guides there not as good as when 50 yrs ago if the rumbling keeps rambling then you may have to have a look at the crank brg shells have you checked no exhaust is making contact anywhere and being overdrive then worth a look at the tail mount , if that gives up it has metal to metal contact on the chassis plate also check engine mounts see if the stg rack is getting too close to the sump just points where contact will give you expensive noises into the body hope that helps Pete 1 Link to comment Share on other sites More sharing options...
Peter Truman Posted November 5, 2023 Report Share Posted November 5, 2023 A slight diversion but still an oil pressure issue, on Friday I started the daughter Mk2 Spit to take it a short drive just checking things before its run home to her 350klm away. It hadn't run for over a month so I did the dead pan start ie choke in spin the engine to the count of 15 then pull the choke out and spin the starter an immediate start with NO rumbles. I let her warm up ie electric fan cuts in then engage reverse and start to back her out THEN I notice the oil pressure gauge is reading less than 15psi (normally 55plus) SH+T run her back into the garage a blip of the throttle still 15psi?? Thinking back to a similar problem with my Vitesse in the early 70's on an early morning run to Teeside Airport the wife was going on a business trip to Yugoslavia I noticed the Vitesse oil pressure had dropped from its normal 80psi to under 40 I backed off and got her there on time, so in the car park I dismantled the Pressure Relief Valve refitted it and all back to normal, car still going strong to this day with no issues or reoccurance and NO engine rebuild YET! So I strip the Spits oil relief valve down no dirt so refit and retry oil pressure still only 15psi? Now the oil pressure gauge is in a mini dash arrangement mounted in the radio space of the Spit dash anti scuttle shake H frame, so me thinks is it the oil pressure gauge, so I try a replacement gauge out of a spare Spit dash board I have start the engine oil pressure immediately over 55psi, BUGger the gauge has failed! So why I have the old presumably failed oil pressure gauge out of the mini dash I retry it an immediate 55psi reading WHAT gives! Now I'd recently had the gearbox cover and H frame out to insulate the cover with Dynomat and top the gearbox up, when refitting the mini dash with oil pressure and voltmeter I noticed the instrument bulb in the oil gauge had failed so I replaced it, in fact I did both gauges, the replacement bulbs being the same volts and watts, but the actual bulb glass section was not spherical but an elongated say 15mm of glass, on viewing the bulb in its gauge mounting I found the longer bulb fouled the bowden tube mechanism I can't repeat what I said! be it enough that I have stocked up with the original fitment bulbs and the long bulbed bulbs are in the rubbish bin. What a waste of a couple of hours, always use original fitment!! 1 Link to comment Share on other sites More sharing options...

JohnD Posted November 6, 2023 Report Share Posted November 6, 2023 (edited) The danger, Paula, is that the standard oil pressure switch triggers at less than 10psi! So if it goes on while you are running, then your oil pressure has been dangerously low for a long time! Other switches are available, that trigger at, say, 25, or else you can get them that are easily adjustable, so you can make your choice - you do need a gauge for that! See Merlin Motorsport for one. https://www.merlinmotorsport.co.uk/s?search=Adjustable+oil+pressure+switch John Edited November 6, 2023 by JohnD 1 Link to comment Share on other sites More sharing options...
Paula Posted November 6, 2023 Author Report Share Posted November 6, 2023 I actually fitted an adjustable one to my campervan. Felt a bit naughty, but it's running great and i've done some long trips. In fact it's becoming my daily driver, which isn't ideal! I may have to bite the bullet and buy a little cheap modern car. What i really need is a garage! Link to comment Share on other sites More sharing options...
Paula Posted February 4 Author Report Share Posted February 4 Hello! I’ve bought a oil pressure gauge from Amazon. it’s telling me. At about 1000 rpm it’s 50 PSI At about 2000 rpm it’s 80 PSI This is ok isn’t it? it’s still very smokey. I’m thinking of sending the head away for a check and refurbish. Is that the best next move? maybe just ignore the rumble of the engine for now. Link to comment Share on other sites More sharing options...
Pete Lewis Posted February 4 Report Share Posted February 4 thats good readings there is only one quoted by triumph thats 40-60 at 2500rpm ( thats from memory not the book ) if you do need to have the head looked you know where i am Pete 1 Link to comment Share on other sites More sharing options...

johny Posted February 4 Report Share Posted February 4 Ok it'll drop as you get to fully hot and also of course as the oil gets older👍 Have you done a compression test at all? I think a sudden increase in oil smoke is more likely to be a broken ring than valve guides as they only wear slowly.... Link to comment Share on other sites More sharing options...

Pete Lewis Posted February 5 Report Share Posted February 5 (edited) did the smoking appear suddenly of its crept up from good to bad over time ?? always do this test with all plugs out and throttles held open one silly way to get smoke is overfilled dashpots the overspill runs down gets in the mixture and then fumes out the exhaust also blocked breather systems there can be a gauze in the rocker cover vent that gets clogged need to dig it out for a wash up Pete Edited February 5 by Pete Lewis Link to comment Share on other sites More sharing options...

It had some serious overheating issues then the smoke started quite quickly. Sounds serious to me. The plugs are very oiled up and the rocker cover had splatters of oil around the breather Link to comment Share on other sites More sharing options...
JohnD Posted February 5 Report Share Posted February 5 Yes, Paula, as Pete says, compression test indicated. If blow-by is increased due to failed piston ring seal, then much more crankcase gas, with oil spray up into the rocker cover and out through the breather. A quick test would be to remove the breather while running. A gentle breeze out is normal, a mighty wind is not! Absolute compression numbers not relevant - you're looking for equal pressures across the block. John Link to comment Share on other sites More sharing options...
Pete Lewis Posted February 5 Report Share Posted February 5 2 minutes ago, JohnD said: you're looking for equal pressures across the block. Ha if you read my troubles with a payen HG we managed equal all at zero across the block !!!!! pop the filler cap off if its as john says your in for maybe a gasket change if its more of e steam train then expect deep rooted wear in the piston area def have alook at the rocker cover for a blocked gauze at the breather outlet do the cheap fix first Pete Link to comment Share on other sites More sharing options...
Paula Posted February 5 Author Report Share Posted February 5 (edited) OK compression test was 90 PSI almost exactly on each cylinder. Popped the cap off and hardly any wind at all coming out of it. It was still very smokey. (see video) and growly. So i thought i'd take it for a run to get it up to temperature and do another oil pressure test. Now here's where it got a bit weird After about 15 mins in traffic and slow driving the smoke cleared up. Buy the time i'd got back home there was no smoke and the engine wasn't growling any more. It's running very nicely but the temperature gauge only ever got to about a 1/4. But it is a bit cold. Normally a run like that would be on the edge of over heating. Maybe i'd over filled something and now it's all cleared out? Maybe he wanted me to plug lots of gauges in him to show i care? So now it's sounding great., Running great and not smoking at all.
