It’s why you can’t put a spin on oil filter conversation kit on. The breather right?

the Vit6 has a open vented tubular crankcase vent in its fitting face to the block is a pack of perforated gauze plates
its worth removing the two bolts ( down near the fuel pump) and clean the plates in case they are clogged
the vent is a long bit of 1" metal pipe exits below the sump flange
Pete
Will do!

I’m going for a big motorway drive tomorrow.
my normal test route. Lots of traffic and a junction on the motorway.Hopefully it will all be fine. I think I over filled it with oil when I added the STP stuff
-
I do have scuba tanks! Maybe i could check with them. Might be too much pressure though.

Going back through my own comments, i've been here before.
I think the chain of events was all from me doing the head gasket and not bleeding the coolant properly. Then over filling the oil.

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. -

did the smoking appear suddenly of its crept up from good to bad over time ??
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

Have you done a compression test at all?
I'll do one tomorrow

Just now, johny said:
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....
I haven't. I can do. I have a gauge

Is that with fully hot and used oil? The relief valve is supposed to open at a max of 55psi but of course both that and the accuracy of the gauge are questionable...
Ah . I'd say i ran it for about 5 mins before checking

just what makes you thing it needs a head off ????
Lots of smoke. So much it's off the road

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
People are often telling me I need my head looking at.
maybe a trip to the mighty Luton! -
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.

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!

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!!
That sounds stressful! maybe it's best not to have a gauge! 😀
I've no idea what my oil pressure is. The light goes off quickly is all i have to tell me.- 1

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
I'm struggling to describe the noise. I'm 90% sure it's coming from inside the engine. I will check all those bits though!
-
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. -

had a donated pair of ramps last month but declined as no one wanted them now wish i could be clever afterwards
belive they went up the tip Grrrr 9 owner moved to france )
tin of STP is simpler but not recommended by the many !!!!
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. -

might be worth dropping the sump and looking at the bearing shell condition(one day !!!)
not a road side task to envy .getting the sump of can be a faf with the oil pump getting in the way
but with the odd knocking and a growl could be worn crank shells
Pete
I'll save that for better weather!
Maybe some ramps too!

I've been out and checked the level and there's no foam.
I went for s drive for about 20mins and it all seemed ok. The smoke cleared up.
I got back and the temp gauge was only 1/3. The thermostat is definitely opening.
Maybe that's all ok now?
Running nicely, But i'm not sure it's sounding as quiet as it used to. Bit of a low end growl. -
-
Also my coolant is red so that's why it's pink foam.
The thermostat is opening now. and he's running nice. i'll check the level again in a couple of hours.
I guess the thermostat is never going to open if it's not in the coolant and just foam.
Really hope it's not the head gasket AGAIN!

I have never seen foam like that when draining the cooling system. Foam is a very poor conductor of heat so that might be the problem. I would flush the system , preferably with a hose pipe, until the water runs clear and without any foam before refilling. It is almost like someone has added screen wash instead of antifreeze, both of which are blue.
I flushed it last week with cleaning stuff. Maybe that caused the foam?
I’ve topped up and I’m running it up to temp now. I’ll let it cool down and check again after

Here's an old picture of a GT6 parked in Harpenden in Hertfordshire some time 1970's i guess.
Thought it might be of interest to someone.
