Gazzar Posted March 5, 2020 Author Share Posted March 5, 2020 Nope. But all metal except the sealing surface. It comes with a applicator. It looks good. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted March 5, 2020 Share Posted March 5, 2020 Ah, hadn't realised what style it was. Yes, doesn't look bad, presume that is loctite type stuff around the outer edge. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted March 5, 2020 Author Share Posted March 5, 2020 Yes. I'm going with it. Most of the brands are in the same price range. Landrover is, as usual, 6 times the price. And probably the same part.... Quote Link to comment Share on other sites More sharing options...
lo-fi Posted March 5, 2020 Share Posted March 5, 2020 Rear crank seal... Can you not measure it and buy a Corteco seal? Many tears when that fails Quote Link to comment Share on other sites More sharing options...
Gazzar Posted March 5, 2020 Author Share Posted March 5, 2020 Yes, it's an option. I've been focusing on the Landrover suppliers. I'll try find a lookup. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted March 5, 2020 Author Share Posted March 5, 2020 Where would I shop for corteco seals? Local bearing place?  Quote Link to comment Share on other sites More sharing options...

Short intake runners will rob you of many low end torques, smoothness, efficiency and ponies. Plugging numbers in here highlights that you want looong runners. You're not trying to build a high rpm race engine. I've seen first hand what happens when this is ignored - funnily enough on a carb > efi converted engine. Guy built himself a very clever manifold that sat right in the valley all nice and neat with multi point injection. Intake runners of about 1.5". It ran like utter garbage. Popped, farted and backfired off idle no matter what the settings, gutless through mid range, disappointing even screaming, guzzled fuel. 70bhp (flywheel) from a freshly rebuilt 2.8 litre engine with a brand new Kent cam. Swap to an original carb manifold with single point throttle body injection and she woke up. Different engine. Smooth, torquey, powerful. Have a play with the calc, it'll show you the way to a good result Something similar to that diesel manifold might kinda work, but it'll be a long way from optimal. Stuck. No idea the duration of a standard cam.  Help? Quote Link to comment Share on other sites More sharing options...

Gazzar Posted March 5, 2020 Author Share Posted March 5, 2020 Where is the runner length calculated from? And is my sums right? 11 before top dead centre =11 Top to bottom =90 47 after bottom dead centre Total = 148? Â Quote Link to comment Share on other sites More sharing options...
Gazzar Posted March 5, 2020 Author Share Posted March 5, 2020 It's not, is it? I need another 90. Quote Link to comment Share on other sites More sharing options...

Gazzar Posted March 5, 2020 Author Share Posted March 5, 2020 It's still nearly a foot and a half!?!?! Ummmm. Single point injection with a carb manifold. Multi point is OUT. Quote Link to comment Share on other sites More sharing options...

No, it'll be pulsed just 4x more often - you don't need to time the fuel squirts to coincide with anything, after all carbs are just a continuously leaky bucket. It's sometimes advantageous to fire fuel at the back of a closed valve as it atomises the fuel and cools the valve. You can also prat around with the settings in MS to do more smaller squirts per cycle which can smooth out fluctuations in the fuel rail... but that's waaaaay over what's worth worrying about in an old Land Rover.

I think you are getting a little hung up on these numbers to be honest! Point me at one non-sports/supercar engine that has runners that are more than a foot long, and I will think it worthwhile. You can of course run a plenum, and then runner length is not so important.... But whatever, anything you can cobble together craft together carefully will fit as long as they aren't ridiculously short. Quote Link to comment Share on other sites More sharing options...

Gazzar Posted March 6, 2020 Author Share Posted March 6, 2020 Thanks, learning as I go... Plenum. I know nothing about plenumi, or plenums. Thanks, still good with SPI stuck on a series manifold. Â Quote Link to comment Share on other sites More sharing options...

That's really useful, thanks. I presume the injector can cope with the workload. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted March 6, 2020 Share Posted March 6, 2020 Yup, if it is up to the power level it will be fine, SPI tend to run larger injectors for this reason. Quote Link to comment Share on other sites More sharing options...
