Colin Lindsay Posted October 1, 2020 Report Share Posted October 1, 2020 4 hours ago, Pete Lewis said: my battery 250lb impact wrench was no use just 2 purfectly proportioned old codgers on a 3ft breaker bar I managed to find the huge screwdriver I once used to jam the camshaft of a 1500 Spitfire, through the fuel pump aperture, whilst I stood on a six foot breaker bar, trying to undo the front pulley. The screwdriver ended up slightly... curved and the pulley stayed put for days. An impact wrench took the pulley off in seconds. Having said that, fan of impact wrenches as I am, I'm worried that stud extractor would snap studs rather than undo them? Link to comment Share on other sites More sharing options...
johny Posted October 1, 2020 Report Share Posted October 1, 2020 ouch! I wonder what that did to the cam chain😬 Link to comment Share on other sites More sharing options...
Colin Lindsay Posted October 1, 2020 Report Share Posted October 1, 2020 That's why the pulley came off... chain, tensioner and all seals replaced. If it affected anything else... well, we haven't found it yet. Link to comment Share on other sites More sharing options...
Paula Posted October 1, 2020 Author Report Share Posted October 1, 2020 I used my new endoscope camera to get a good look. Ignore the cotton bud! I was cleaning the area before insertion. 😳 My Movie 2.mp4 Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 1, 2020 Report Share Posted October 1, 2020 cant tell but guess thats with feargal running ? if so then its combustion pressures making the bubbles back to try a re torque before you get carried away, have you been loosing coolant without knowing where its gone ??recently any misfire when starting from overnight ??? due to coolant in the bores those are some simple signs the gasket has failed badly a few bubbles escaping may just be its not clamped enough start there before you get carried away with ripping it to bits , most gasket failures get combustion silly high pressures gasses into the water jacket rather than a few psi of coolant getting into bores , as compression explosive is far more powerful than the the coolant pressure Pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted October 1, 2020 Report Share Posted October 1, 2020 Ooooohhhh... that's not good! That's a lot of fluid loss. It looks like it's with the engine running, Pete, and that's being blown out rhythmically as the engine rotates. Head off! (BTW what endoscope did you buy, Paula?)

poppyman Posted October 1, 2020 Report Share Posted October 1, 2020 Further to what Pete say's above, take the plugs out that end.... You will probably find a very nice clean one and that will tell you for sure. Tony. Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 1, 2020 Report Share Posted October 1, 2020 if it was a composite or copper gasket i would agree but this has the thin steel shim they dont blow apart as there are no crimped on fire rings its all a one piece lump of tin motto do the easy first , then go mad at it Pete Link to comment Share on other sites More sharing options...

It doesn't look like a lot to me, just a small bit of bubbling. I'm with Pete - try the re-torque first. Link to comment Share on other sites More sharing options...
Colin Lindsay Posted October 1, 2020 Report Share Posted October 1, 2020 It's more than a slight weep; it's bubbling out and after a few miles of driving would be a substantial loss to the system. Not the sort of thing that will be sorted by a bottle of Bars Leaks or the like; so I'll stick with my own - personal - opinion that it's a lot, and needs a bit of work.

NonMember Posted October 1, 2020 Report Share Posted October 1, 2020 I agree that Bars Leaks won't help because it rarely does. But I think the bubbles you're seeing are combustion gasses and it only needs a tiny bit of coolant to be present for that sort of effect. Given that it's a 1600 with the tin gasket, it's likely it will respond to re-torqueing. If not, then you're right that the head needs to come off, but I don't think there's a lot of coolant loss (and Paula didn't report coolant loss).

Paula Posted October 1, 2020 Author Report Share Posted October 1, 2020 It was running yes. i have been losing coolant. But not lots. After my Weymouth trip it took quite a bit, maybe 3/4 of a pint, but that was a 300mile trip. sometimes it does take a bit to get all the cylinders firing, but this morning it was fine and it’s running very nicely. I might as well do a re toque first. Hopefully in the next couple of days. I’m still using it. Hope that’s ok. Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 1, 2020 Report Share Posted October 1, 2020 as for Bars leak pellets we fitted one in the bottom rad pipe of every truck to solve early life seepage from so many pipes and hoses that was up till 93 , maybe things have moved on but they and k seal are a leak stopper not a repair agent to solve all ills Paula's is bubbling so compression is escaping to atmosphere pete Link to comment Share on other sites More sharing options...

I hope it is an easy fix, but my idea of little coolant loss is a few drops; everything else is sleepless nights for me and one eye on the temp gauge! I'm just concerned that the gases are blowing a lot out as spray, and it's worse than it looks... but here's hoping. 1 Link to comment Share on other sites More sharing options...
Paula Posted October 2, 2020 Author Report Share Posted October 2, 2020 Ok so things that have to come off for access to the head nuts is Exhaust manifold rocker cover anfd rocker shaft? Do i need to get the inlet manifold and carbs off too? Will i have to completely remove the manifold or just pull it out of the way? I'm going to try and have a go tomorrow before work Link to comment Share on other sites More sharing options...

I'm going to try and have a go tomorrow before work Just remove one item at a time until you can access them all. With regards to the manifold you may be able to just slide it out of the way, provided the connections etc are long enough to do so, and make sure you don't let it hang off anything that might bend or snap under the weight, like a pipe or a cable. 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 2, 2020 Report Share Posted October 2, 2020 yes there should be enough flex to clear to just get to the nuts . the down pipe is the most rigid controller but both manifolds will lever out the way you dont need a lot if you remove the bolts from the dumb bell clamps it worth cleaning the threads so you dont get any its tight but not clamping oddities as the crud in the thread can block retightening.

Pete Lewis Posted October 3, 2020 Report Share Posted October 3, 2020 paula while its raining you may save some coolant loss if you just undo the rad filler to its fist click , keeps the cap on but stops any pressure building up do any head work when the suns back Pete Link to comment Share on other sites More sharing options...
