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.

Test drive complete. Good hour drive including traffic and motorway. I think he deserves a wash now!

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

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.

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

I'll do one tomorrow

I haven't. I can do. I have a gauge

Ah . I'd say i ran it for about 5 mins before checking

Lots of smoke. So much it's off the road

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!

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.

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.

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.

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.

Been using 4 Life https://shop.tssc.org.uk/product/forlife-radiator-fluid-5-litres

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 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
