Essex Roller rockers

Thanks those are all worthwhile points. I suppose the one that had me a little hooked was the thought of increased ratio - valve lift - power but the clearance/tappety thing is also worthwhile - I spent ages with mine recently to solve that

Yes that's what I thought. It can't have moved by much though, just a 2 or 3 mm I think
When you say shimming in order to avoid taking apart, is that shimming between door and hinge or between hinge and body or something else? I suppose it will be necessary to detach the hinge anyway

Essex Roller rockers

What's the advantage o using these? Is there a change to ratio and therefore valve opening? If so what does that achieve power wise?

Spegru SE6a

A bit of a faux pas this weekend when the wind took the drivers door and swung it open hard. Since then the door edge catches the edge of the dorr opening as it opens, making a nasty creaking noise as one beit of fibreglass grates over another. I've had a good look around and cant see any visible da...

Tappet adjustment query

just by way of completeness, I thought I'd remeasure with a feeler guage while changing the cork gaskets. Perhaps oddly they all measured up fine albeit very tight on the guage. Just one seemed a bit too tight - seemed to be 0.2 vs 0.3mm (Inlet on No2) so I loosened that a bit. Hard to say whether t...

Essex head gasket failed?

I looked at those but was unsure whether it was a header tank or an expansion tank. In the end I bought another cheapo item 321417918816 which definitely has a pressure cap 2.5 Litres but no sight tube. Not fitted it yet though....
I'm just wondering whether it will help anything

Essex head gasket failed?

Regarding heater tanks & Expansion bottles, I have been wondering about repacing my plastic expansion bottle with an alloy Expansion tank plumbed into the the bottom heater hose. The objective being to reduce/ eliminate water loss with (effectively) a larger radiator top tank. After all this is how ...

Rear Wiper & Park Position?

I've just uploaded a couple of videos showing what happens to the rear wiper as it parks and the motor internals as they park. It seems that the motor actually changes direction via a reversal in polarity. A bit weird really. I wonder if any other cars have this system? https://www.youtube.com/watch...

Tappet adjustment query

I managed to upload a video of me using the dial guage and some of the troubles I had with it to begin with. I got better at it later on!

I think hope this is showing 0.30mm on an inlet!

Tappet adjustment query

Sideways movement can cause a big change in the reading (say 0.3mm) caused I think by the the uneven top surface plus the fact that the rockers can also rock sideways a bit - which not only alters the reading if the guage is not centred but i think also changes due to the way the rocker sits on the ...

Tappet adjustment query

well it turned out that my dial guage, or rather its very simple stand would not allow be to attach it anywhere useful - so I bought another one of ebay that has a multi position arm. It has a magnetic base and I attached it in various places on the side of the cylinder heads and exhaust manifold. T...

Rear Wiper & Park Position?

Stainless and GRP are both inert but a combo of different light exposure and dampness under the plate will certainly affect how it all looks once the plate is off

BTW I wanted to post a video of the motor park in action but the system doesnt like MP4

Rear Wiper & Park Position?

An Update. Wiper is now working properly. I would say 'normally but indeed what it does is very strange and a 'Dance' is probably a good description. The insides of the motor are different to others of a similar appearance It seems that the parking mechanism involves a reversal of motor polarity and...

Auto to Manual conversion 6B/GTC 2.8

Does this RX8 gearbox work out with the 3 litre Essex to replace the Type F? I note that someone on Ebay is doing an adaptor plate for the Essex https://www.ebay.co.uk/itm/303229326887?_trksid=p2045573.m570.l5999&_trkparms=gh1g%3DI303229326887.N36.S1.R1.TR2 but is advertising it to replace the Type ...

Rear Wiper & Park Position?

That's very interesting. That linked topic diagram reveals a very odd motor crank arm. Looks like this is not just a standard lucas motor. I might even take it out for a look inside... It's not parking right now but I wonder if that's because If messed up the connection behind the rotary switch But ...
